The format follows ## [Unreleased] +### Changed + +- **Tool retrieval is BM25F over five fields, with stemming and Russian query + expansion.** A tool is indexed as its name, `search_hint`, the first sentence + of its description, the rest of it, and its parameter names and + descriptions, each weighted (`tool_retrieval_name_weight`, + `tool_retrieval_search_hint_weight`, `tool_retrieval_summary_weight`, + `tool_retrieval_description_weight`, `tool_retrieval_parameters_weight`, + `tool_retrieval_bm25_k1`, `tool_retrieval_bm25_b`). Identifiers are split + (`BrowserOpen` matches "browser open"), `ё` is folded, conversational + fillers are stopwords, and both sides are stemmed with the Snowball Russian + and Porter English stemmers. A Russian query is expanded through a bundled + Russian-to-English lexicon (`tool_retrieval_lexicon_weight`), which is what + lets it find tools described only in English. On a labelled set of 656 + English and Russian queries against about 700 tools, Recall@5 rose from 0.41 + to 0.67, and to 0.78 with a Russian `search_hint` on every host tool. See + `docs/tools.md`. +- **`ToolRegistry.search` returns tools in rank order**, best first, ties by + name. It used to re-sort its result by name, which hid which hit fit best. + The advertised surface from `compute_effective_surface` stays in name order. +- **The index is built once per catalogue version** and cached on the registry + instance, instead of re-tokenising every tool on every query: about 0.3 ms per + query at 700 tools, down from 15–20 ms. +- **The per-turn clip uses the normalized fallback too** when nothing scores, + as `search` already did. The fallback no longer counts one- and two-letter + words and stopwords of a description, which made the article "a" match any + query token containing the letter. +- `IToolRegistry.search` and `compute_effective_surface` take an optional + `retrieval: RetrievalSettings`; the loop passes + `RetrievalSettings.from_constants(rc)`. +- **The per-message clip is off by default, and pinned tools no longer count + against it.** `tool_retrieval_top_k` defaults to `0` (off) and now counts only + the tools retrieval adds; counted with the pins, a floor of fourteen under the + old default of twelve left the clip no room to retrieve anything. Clipping per + user message is kept as an opt-in and documented as not recommended. +- **`tool_definitions_ratio` is enforced** and defaults to `0.25`. It was + derived into a budget that nothing held the surface to. +- **Discovered tools are appended to the surface in discovery order** instead of + being sorted into it, so loading a tool changes only the end of the tool list. + The context manager's pin LRU (`pin_tool`, `pinned_tool_names`) is replaced by + `discover_tool`, `note_tool_used`, `discovered_tool_names` and + `evict_discovered_tools`; `pinned_tool_max_count` is applied, least recently + used first, only after compaction, at a turn boundary and when a run starts. +- **The snapshot schema is version 7.** `context_manager_pinned_tools` becomes + `discovered_tools` (name and last use, discovery order) beside the new + `deferred_tool_groups`; the upcaster lifts a version 6 payload. +- **`tool_surface_advertised`** carries `discovered_tool_names` (discovery + order) in place of `toolsearch_pinned_tool_names`, the held-back groups + (`deferred_tool_groups`, `deferred_tool_count`, `tool_deferral_reasons`), and + the source `discovered` in place of `toolsearch_pin`. +- **An unknown tool name is answered with up to three near names** the policy + admits: `unknown tool: 'X'. Did you mean: A, B, C?` +- An engine built without a host run state now carries its own constants on + `run_state.rc`, so core tools read the run's tunables. +- **A description's first sentence no longer ends at an abbreviation** such as + "e.g.", "i.e.", "vs.", "т.е." or "напр.", nor at a full stop inside + brackets; "etc." and "т.д." end it only before a capital. `ToolSearch` shows + that sentence as a tool's line, and it used to read "Transition an issue to a + new status (e.g.". + +### Added + +- **Tool groups and deferral.** `ToolGroup`, `IToolRegistry.declare_group`, + `undeclare_group` (for a group whose tools are gone, such as a removed MCP + server's) and `tool_groups`; a tool joins a group by its `tool_group` class attribute or a + declared name prefix. With `tool_deferral_mode = "auto"` (the default, inert + until a group is declared and a discovery tool registered) dynamic groups are + held back, and other groups largest first while the surface is over + `tool_definitions_ratio` of the window or over `max_advertised_tools`. + Held-back groups are named in a byte-stable catalogue block in the system + prompt, with exact tool names or an exact prefix and count + (`tool_catalogue_max_listed_names`). The decision is made again when the + catalogue, the groups or the host's visibility policy change, so tools a + host switches on mid-run are held back like the rest, with the decision in + force as its floor, so the catalogue does not flip mid-run. A decision a + snapshot carries is a floor too: a dynamic group it does not name is still + held back and the limits still apply. Without a discovery tool, groups are + held back only over `max_advertised_tools`, and the catalogue says to call + by exact name. See `docs/tools.md`. +- **`ToolSearch`** (`protocore.tools.ToolSearchTool`): free-text search with up + to `tool_search_max_results` hits in rank order, one line each, loading the + first `tool_search_autoload_count`; `select:Name1,Name2` (or a `select` + argument, a list or a comma-separated string) loads exact names and answers + an unknown one with the nearest admitted names. A tool already in the tool + list is reported as such, never as loaded, and the description says the tool + loads tools only — skills are not tools. It respects the live visibility + policy and a child run's declared tool set, which the dispatcher stamps on + every call (`TOOL_VISIBILITY_POLICY_METADATA_KEY`, now + `protocore.tool_visibility_policy`, and `TOOL_ALLOWLIST_METADATA_KEY`); with + no policy it admits nothing. It is advertised only while something is held + back. +- `ADVERTISED_TOOLS_METADATA_KEY`: the loop stamps the names the calling + request advertised on `ToolContext.metadata`. +- A call of a registered tool the request did not advertise still runs and now + loads the tool; events `tool_discovered` and `tool_unadvertised_call`. When + such a call fails on its arguments, the error ends with the tool's line + (`It takes: Name(param1*, param2) — first sentence`), the form `ToolSearch` + lists tools in, so the retry need not guess again — only for a tool the + policy and the child's declared set admit. +- `QueryEngineConfig.discovered_tools` seeds a new run with the tools the last + run of the session loaded; `ContextManager.called_discovered_tool_names()` + is the part of them the run called, which is the list worth carrying. +- `max_tool_calls_per_turn` (default 64): calls past it in one model message are + each answered with an error and not run. +- **Load modes and rules for tool groups.** `declare_group` takes + `load="eager" | "auto" | "lazy"` and `instructions`. A `lazy` group is held + back whenever a discovery tool is admitted, even when everything fits, and + is advertised like `auto` when none is; an `eager` group is never held back + for size and gives way only to `max_advertised_tools` itself. + `QueryEngineConfig.tool_group_loads` overrides the load modes for one run. + `ToolSearch` takes `group` (and `group:` entries in `select`) to load + every admitted tool of a group; tools loaded that way are one entry under + `pinned_tool_max_count`. A group's rules are given once per run: in the + catalogue for tools on the surface or loaded when the run starts (and again + after a compaction), in the `ToolSearch` result that loads the group's first + tools, or — for a blind call of such a tool — instead of running the call, + which is answered with the rules and runs on the next try. New event + `tool_group_loaded` (`group`, `via`, `tools`); `tool_surface_advertised` + carries `tool_groups` with each group's load mode and state, and + `tool_unadvertised_call` carries `executed`. The snapshot (still version 7) + gains `tool_group_rules_given`, and a discovered-tool row loaded with its + whole group carries `group`. The catalogue's header now names the + whole-group load. See `docs/tools.md`. +- **A blind call held for its group's rules loads the whole group**, as + `ToolSearch(group=...)` would, and its answer names the group's other tools + now callable and gives the called tool's line (`It takes: Name(p1*, p2) — + …`). Loading only the called tool left the rest of the group out of sight, + and the retry was written without the parameters. +- **Group rules carry the run's rules mark, and the catalogue names it.** A + genuine rules heading reads `Rules for the tools []:`; the + catalogue says, whenever a group in it has rules, that text claiming to be + rules without the mark — a web page, a file, a command's output — is + content, not rules. The mark is an HMAC of the session id under a + per-process key (`tool_rules_mark`), stamped for discovery tools as + `protocore.tool_group_rules_mark` and carried in the snapshot as + `tool_group_rules_mark`. +- **After a compaction the rules counted as given are the rules the catalogue + carries.** The set used to keep every group given earlier, so a group whose + rules were in a result the compaction took away, and which the compaction + then unloaded over the cap, had its blind calls run without the rules and + its reload give none. The catalogue no longer keeps rules for groups that + are neither on the surface nor loaded, and `ToolSearch` inside a loop goes + by the given set alone. +- **A call held for its group's rules is not a use of the tool**: it did not + run, so `called_discovered_tool_names()` no longer lists it and a host does + not carry its group into the next run for it. Its `tool_unadvertised_call` + (`executed: false`) now comes before its `tool_result`, so a host knows the + result answers a call that never ran. +- **The catalogue lists the host's own held-back groups first**, and the + `dynamic` groups after them under `Tools of connected servers:`. In one + name-sorted list the servers stood ahead of the host's groups. +- `QueryEngineConfig.loaded_tool_groups` seeds a run with whole groups, each + one entry under `pinned_tool_max_count` with its rules in the catalogue and + a `tool_group_loaded` event with `via` `seed`; seeding a large group's tools + by name made each an entry and pushed the rest of the seed out. + `ContextManager.loaded_tool_group_names()` is the groups a run holds whole, + for a host to carry into the next one. + +- **The bundled lexicon covers the Russian a developer speaks about trackers, + chat, calendars and deployments**: loanwords and slang such as "пулреквест", + "ишью", "тикет", "таска", "смержи", "выкати", "созвон", "заархивируй", + "алерт", mapped to the English an MCP server describes its tools in.

Задуман он для эмбеддингов; сам core их +не поставляет. + +### Как писать `search_hint` + +Описание пишется для модели, по-английски; подсказка — для того, кто ищет. +Она должна быть у каждого инструмента хоста: + +- **8–14 английских синонимов** действия и его объекта, не повторяя имени + инструмента ("screenshot capture snap picture image page"). +- **10–16 русских слов**: словарная форма **и** повелительное наклонение каждого + глагола (открыть открой, напомнить напомни), существительные объектов и + сленг и кальки, которые люди действительно пишут (скинуть скинь, глянуть + глянь, коммит, пулреквест, напоминалка). +- **Избегайте общих слов**, которые совпадут и с чужими инструментами, — + "запрос", "задача", "сервер" без уточнения уводят запросы к не тому + инструменту. + +--- + +## Отложенные группы инструментов + +Отдавать все инструменты — лучшая поверхность, пока она помещается: на +нескольких моделях поверхность примерно из двухсот инструментов отвечала не хуже +любого способа искать инструменты по требованию. Перестаёт помещаться она двумя +способами, и оба — стены, а не склоны. Определения могут занять столько окна, +что разговору не останется места, а некоторые провайдеры отказывают в запросе +сразу, если инструментов больше фиксированного числа (встречаются 128 и 350). +Хост, подключивший большой MCP-сервер, упирается в одну из стен на первом же +запросе. + +Поэтому цикл умеет откладывать целые **группы** инструментов: не класть их в +`tools`, называть одним блоком в системном промпте и загружать по запросу через +`ToolSearch`. Пока поверхность помещается, ничего из этого не происходит — если +только хост не попросил: группа, объявленная **ленивой** (`lazy`), откладывается +и тогда, потому что это семейство, которое прогону нужно редко. + +### Группы + +Инструмент попадает в группу по атрибуту класса `tool_group` (читается через +`getattr`, как `search_hint`) или по префиксу имени, который объявил хост: + +```python +registry.declare_group("scheduling", "Timed and recurring jobs") +registry.declare_group( + "github", "GitHub issues and pull requests", dynamic=True, prefix="Mcp_Github_" +) +registry.declare_group( + "browser", + "Drive a web browser", + prefix="Browser", + load="lazy", + instructions="Ask the user before submitting a form.", +) +registry.register(ToolSearchTool(registry)) +``` + +`ToolGroup(name, description, dynamic, prefix, load, instructions)` живёт в +`contracts/tool_registry.py`, у `IToolRegistry` появились `declare_group` и +`tool_groups`. `declare_group(name, description, *, dynamic=False, prefix=None, +load="auto", instructions="")` отклоняет режим загрузки вне `TOOL_GROUP_LOADS`; +повторное объявление группы заменяет описание, режим и правила, и цикл +принимает решение заново на следующем запросе. Явный `tool_group` важнее префикса; из префиксов побеждает самый +длинный. Членство в группе не уходит на провод и не входит в дайджест +поверхности. **Динамическая** группа — та, состав которой не код хоста: прокси +MCP-сервера. + +`undeclare_group(name)` забывает группу; забыть не объявленную — не ошибка. +Хост вызывает его, когда инструменты группы ушли насовсем — прокси MCP-сервера, +который оператор выключил или удалил: объявление переживает свои инструменты, и +оставленное займёт префикс сервера, добавленного позже под тем же именем. Ни +объявление, ни удаление группы не меняет поколение каталога реестра: группы не +влияют на результат поиска, а решение цикла об откладывании привязано к самим +объявленным группам. + +### Режимы загрузки + +`load` группы говорит, когда она объявляется: + +| `load` | Откладывается | +|---|---| +| `eager` | никогда из-за размера; сдвинуть её может только жёсткий лимит провайдера на число инструментов | +| `auto` (по умолчанию) | по правилам ниже: динамические сразу, остальные — пока поверхность превышает предел | +| `lazy` | всегда, когда прогону допущен инструмент обнаружения, при любом размере | + +`lazy` — для семейств инструментов, которые прогону нужны редко: дюжина +инструментов браузера, использованная в одной сессии из ста, стоит своих +определений на каждом запросе остальных девяноста девяти; отложенная, она стоит +одной строки каталога и одного вызова на загрузку. Прогон без инструмента +обнаружения считает `lazy` равным `auto`: единственным путём тогда был бы вызов +вслепую по точному имени, а он дороже определений. Группа, которую называет +только атрибут `tool_group` инструмента и которая не объявлена, — `auto`. + +`eager` сильнее бюджета по токенам, правила динамических групп и запаса на +загруженные инструменты, но не самого `max_advertised_tools`: запрос сверх +лимита провайдера отклоняется целиком, и никакой режим этого не стоит. Поэтому +жадная группа откладывается, только пока поверхность и с отложенными всеми +остальными группами всё ещё превышает этот лимит, — самая большая первой. +Группа, ставшая жадной, выходит из нижней границы прежнего решения (см. ниже): +оператор попросил её по имени. + +`QueryEngineConfig.tool_group_loads` — отображение «имя группы → режим» — +переопределяет объявления на один прогон; значение вне трёх отклоняется. Через +него хост передаёт настройки оператора и исключения отдельной сессии, не +переобъявляя группу, общую для всех сессий. Оно входит в ключ, по которому +принимается решение об откладывании. + +### Когда группы откладываются + +`tool_deferral_mode` по умолчанию `"auto"`, `"off"` выключает механизм. В +`auto` один раз за прогон — и заново, только если меняются каталог или группы +реестра либо политика видимости хоста, — цикл измеряет поверхность, которую +иначе отправил бы. Политика учитывается потому, что хост может включить +инструменты посреди прогона, заменив её и ничего не регистрируя; пины, которые +прогон добавляет за загруженные инструменты, не учитываются, так что загрузка +инструмента решение не пересматривает: + +1. откладываются все **ленивые** группы, самые большие первыми, если допущен + инструмент обнаружения; +2. откладываются все **динамические** группы, кроме жадных, самые большие + первыми; +3. затем, пока поверхность превышает предел — определения больше + `tool_definitions_ratio` окна или их число больше `max_advertised_tools` с + запасом на `pinned_tool_max_count` загруженных инструментов, — остальные + группы, самые большие первыми; жадные последними и только пока превышен сам + лимит по числу. + +Никогда не откладываются: обязательный пол (`forced_pinned`), явно закреплённые +инструменты, инструменты `always_load`, сам инструмент поиска и любой +инструмент вне групп. Хост, который хочет сделать инструмент откладываемым, +говорит об этом, помещая его в группу. + +Если инструмент обнаружения (роль `discovers_tools`) не зарегистрирован или не +допущен, вернуть отложенный инструмент можно только вызовом по точному имени, +поэтому группы откладываются лишь тогда, когда поверхность больше +`max_advertised_tools` — провайдер отклонил бы запрос целиком, — сначала +динамические; бюджет по токенам тогда не применяется. Каталог в этом случае +говорит вызывать по точному имени, а не указывает на поиск, которого у модели +нет. + +Отложенные инструменты остаются **допущенными** политикой видимости — их просто +не объявляют. Модель, вызвавшая такой инструмент по точному имени, получает +результат (см. [ниже](#вызов-необъявленного-инструмента)). + +Решение принимается один раз, а не на каждый запрос, потому что каталог, который +из него получается, стоит в голове кэшируемого промпта: пересчитываемый на +каждом запросе, он сдвигался бы при каждой смене ответа. Когда смена каталога +или политики заставляет принять его снова, действующее решение — его нижняя +граница: отложенная группа остаётся отложенной, пока в ней есть инструменты, и +добавить к ней может только динамическая группа, впервые допущенная этому +прогону, или превышенный теперь лимит. Другая сессия, включившая сервер, или +выключенный посторонний инструмент каталог не меняют. + +### Каталог + +Когда что-то отложено, в системном промпте после каталога навыков стоит один +блок ``: фраза о том, что инструменты можно загрузить в любой +момент, и как — `ToolSearch(group="")` для целой группы, `select:` и +точные имена для отдельных инструментов или описание, — фраза о том, что +отдельный инструмент лучше обходного пути через общий, и по строке на +отложенную группу — описание и **точные** имена инструментов, а для группы, +объявленной префиксом, у которой отложено больше +`tool_catalogue_max_listed_names` инструментов, — точный префикс и их число: + +```text +- browser: Drive a web browser. Tools: BrowserClick, BrowserOpen +- scheduling: Timed and recurring jobs. Tools: IntentCreate, ScheduleCreate + +Tools of connected servers: +- github: GitHub issues and pull requests. Tools: Mcp_Github_* (26 tools) +``` + +Собственные группы хоста идут первыми, а `dynamic`-группы — подключённые +серверы — после них, отдельной секцией. Когда всё шло одним списком по имени, +дюжина строк серверов стояла перед группами хоста, и модель, читающая сверху, +принимала их за весь каталог: вела браузер сервера или оболочку и так и не +загружала группу, сделанную для этой работы. Пробовали и фразу над группами +хоста, называющую эти обходные пути: под ней модели чаще загружали группы, но +задачу решали не лучше, так что её нет. + +Точные имена важны: модель, которой приходится угадывать имя, ошибается в +регистре. Вторая фраза важнее, чем кажется: модель, не видящая инструмента, +тянется к ближайшему видимому (сервис через команду оболочки, две правки вместо +одной множественной), и обычно отложенный инструмент остаётся неиспользованным +именно так, а не из-за неудачного поиска. Блок строится из решения, каждая секция +в порядке имён, поэтому он побайтно одинаков на каждом запросе и после возобновления. +Когда ничего не отложено и ни у одной группы нет правил, блока нет, и промпт в +точности такой же, как без групп. + +### Правила группы + +Группа может нести `instructions` — правила работы с её инструментами: какой +браузер вести, о чём спросить до действия. Они даются один раз за прогон там, +где инструменты группы впервые оказываются перед моделью, и никогда — для +группы, которой прогон не касается: + +- **В каталоге** — для инструментов, которые есть с самого начала: группа, + оставшаяся на поверхности, и отложенная группа, часть инструментов которой + загружена к началу прогона (посев хоста или возобновлённый снапшот). Правила + отложенной группы стоят под её строкой с отступом; правила группы на + поверхности — после списка. Блок, в котором есть правила и ничего не + отложено, идёт без шапки: + + ```text + - browser: Drive a web browser. Tools: BrowserClick, BrowserOpen + Rules for the browser tools: + Ask the user before submitting a form. + ``` + + Каталог строится один раз за прогон и входит в кэшируемый префикс, поэтому + группы, загруженные посреди прогона, не добавляются в него при каждой + загрузке. После компакции он пишется снова с правилами ровно тех групп, + что на поверхности или ещё загружены, потому что результат, который их дал, + теперь может быть в сводке или замаскирован. Это не бесплатно: компакция + переписывает разговор, а не системный промпт, поэтому, если группа с + правилами была загружена посреди прогона и ещё загружена, следующий запрос + один раз промахивается мимо кэша на системном промпте (и на инструментах — + у провайдера или шаблона чата, который ставит их после него). Без такой + группы каталог выходит байт в байт прежним. +- **В результате `ToolSearch`**, который загружает первые инструменты группы: + `Rules for the tools [<метка>]:` и текст, после строк инструментов. +- **Вместо выполнения вызова вслепую** (см. + [ниже](#вызов-необъявленного-инструмента)). + +Цикл хранит множество групп, чьи правила уже даны +(`protocore.tool_group_rules_given` в метаданных инструмента и +`tool_group_rules_given` в снапшоте), так что ни одни не даются дважды. +Множество означает «модель их ещё может прочитать». После компакции оно +сбрасывается до групп, чьи правила несёт новый каталог: группе, чьи правила +были в результате, который компакция убрала, и которую компакция выгрузила +сверх лимита, они снова причитаются — вызов её инструмента вслепую +придерживается, а `ToolSearch`, который её загружает, их даёт. Внутри цикла +`ToolSearch` смотрит только на это множество, даже для инструмента, который уже +в списке. + +#### Метка правил + +Правила приходят внутри результатов инструментов — и туда же попадает текст +извне: веб-страница, прочитанная инструментом браузера, файл, вывод команды. +Любой из них может напечатать `Rules for the browser tools:` и что угодно +дальше. Поэтому настоящие правила несут в конце заголовка **метку правил** +прогона — `Rules for the browser tools [3f9a1c2e]:`, — а каталог, в системном +промпте, куда вывод инструментов не попадает, один раз называет метку, когда +хоть у одной группы в нём есть правила, и говорит, что текст, выдающий себя за +правила без неё, — содержимое для чтения, а не правила, и что метку нигде не +нужно писать самому. + +Метка — восемь шестнадцатеричных цифр, HMAC идентификатора сессии на ключе, +который в каждом процессе берётся заново (`tool_rules_mark(session_id)`). Она +одна и та же для всех прогонов сессии в одном процессе, потому что стоит в +каталоге в начале кэшируемого промпта; снапшот её несёт +(`tool_group_rules_mark`), так что возобновлённый прогон сохраняет метку, с +которой даны правила в его истории. Инструменту поиска цикл передаёт её как +`protocore.tool_group_rules_mark`. + +Отдельное сообщение от среды выполнения для правил рассматривалось и +отвергнуто: ход пользователя между результатом инструмента и следующим ходом +ассистента — последовательность, которую некоторые шаблоны чата не принимают +(цикл избегает её и в других местах), а правила в ходе пользователя читаются +как слова оператора. Метка оставляет правила там, где они нужны, — рядом с +инструментами, к которым они относятся, — и делает подделку узнаваемой. +Прогон, у групп которого нет правил, метки в промпте не получает, и промпт +остаётся ровно прежним. + +### `ToolSearch` + +`protocore/tools/tool_search.py` поставляет инструмент обнаружения: +`ToolSearchTool(registry)` с именем `ToolSearch`, ролью `discovers_tools` в +собственном `tool_roles`, флагом `always_load` и безопасный для параллельных +вызовов. Цикл объявляет его **только пока что-то отложено**: когда весь каталог +на поверхности, искать нечего, а модель, которой предложили ненужный поиск, +тратит на него ходы. + +- `query` свободным текстом возвращает до `tool_search_max_results` совпадений, + лучшее первым, по строке на каждое — `Name(param1, param2*) — первая фраза`, + обязательные параметры со звёздочкой, — и загружает первые + `tool_search_autoload_count`. Модель, которая ищет, почти всегда находит нужный + инструмент среди первых трёх. +- `select:Name1,Name2` загружает ровно эти инструменты (имя в другом регистре + тоже принимается). На неизвестное имя приходят ближайшие допущенные имена. + Имена можно передать и отдельным аргументом `select` — списком или строкой + через запятую: модели сами тянутся к такому написанию, и отказ стоит им + лишнего хода. Имена важнее описания, переданного рядом. +- `group` загружает все допущенные инструменты одной группы, названной точно + (имя в другом регистре тоже принимается); `select` принимает также элементы + `group:` рядом с именами инструментов. На неизвестную группу приходит + список групп, доступных прогону. Результат перечисляет инструменты группы + по строке, как при любой загрузке. Инструменты, загруженные целой группой, — + **одна запись** под `pinned_tool_max_count` и выгружаются вместе: модель, + попросившая группу, не заметит, что вытеснение оставило от неё половину. +- Первые инструменты группы с правилами, загруженные вызовом, приносят правила, + один раз (см. [Правила группы](#правила-группы)). +- Первые строки результата говорят, какие инструменты теперь загружены и + доступны, и отдельно — какие из запрошенных или найденных **уже были в списке + инструментов**. Что объявил вызвавший запрос, цикл сообщает инструменту + (`ADVERTISED_TOOLS_METADATA_KEY`; ставится после слияния операторского + конверта, так что подделать его нельзя). «Loaded» про инструмент, который у + модели и так был, вводит в заблуждение: модель, которую попросили + воспользоваться навыком, искала его, получила «Loaded: WebSearch», решила, что + навык загружен, и так его и не открыла. Об этом говорит и описание: инструмент + загружает только инструменты, а навык — не инструмент. +- Живая политика видимости читается из `ToolContext.metadata` + (`TOOL_VISIBILITY_POLICY_METADATA_KEY`, `protocore.tool_visibility_policy`), + рядом — объявленный набор инструментов дочернего прогона + (`TOOL_ALLOWLIST_METADATA_KEY`), поэтому поиск никогда не показывает, не + предлагает и не загружает инструмент, который отклонит гейт диспетчеризации, + а заблокированное имя никогда не всплывает как «похожее». Диспетчер + присваивает оба ключа при каждом вызове, а не ставит их, только если их нет, + так что значение, уже лежавшее в метаданных, не подменяет то, что применяет + гейт. Без политики в метаданных поиск не допускает ничего. + +Инструмент только ранжирует и сообщает. Что он загрузил, он называет под +`TOOLS_LOADED_METADATA_KEY` в метаданных результата — группы, загруженные +целиком, под `TOOL_GROUPS_LOADED_METADATA_KEY`, группы, чьи правила он дал, под +`TOOL_GROUP_RULES_METADATA_KEY`, — а загружает цикл — он +владеет поверхностью, — веря этому ключу только от инструмента с ролью +`discovers_tools` и только для имён, которые допускает политика (и объявленный +набор инструментов дочернего прогона). Настройки читаются из констант прогона в +`ToolContext.run_state.rc`; движок, собранный без состояния прогона от хоста, +кладёт туда собственные константы. + +### Порядок обнаружения и кэш промпта + +Загруженные инструменты **дописываются** в конец объявленного списка в порядке +обнаружения и там остаются. Базовая поверхность остаётся отсортированной по +имени и не двигается, когда что-то загружается, а загруженный инструмент не +двигается, когда загружается следующий, поэтому провайдер с кэшем по префиксу +перечитывает только хвост: одна загруженная схема стоит порядка пары тысяч +некэшированных токенов, а не всего префикса. Найденный инструмент, который уже +на поверхности, повторно не загружается. + +Прогон хранит загруженные инструменты в порядке обнаружения вместе со временем +последнего использования (`ContextManager.discover_tool`, `note_tool_used`). +`pinned_tool_max_count` ограничивает их число, но выгружает давно не +использованные только там, где префикс промпта и так начинается заново: после +компакции, на границе хода (`rearm`) и в начале прогона. Выгрузка посреди +прогона выдернула бы схему из-под модели, которая, возможно, как раз собирается +её вызвать, и стоила бы кэшу ровно того, что ограничение должно экономить. +Единственное исключение — лимит провайдера: если базовая поверхность вместе с +загруженными инструментами превысит `max_advertised_tools`, давно не +использованные загруженные инструменты не попадают в этот запрос (оставаясь +загруженными). + +Загруженные инструменты и отложенные группы переносятся в снапшоте +(`discovered_tools`, `deferred_tool_groups`), и возобновлённый прогон сохраняет +решение, а не измеряет заново, — как нижнюю границу: динамическая группа, +которой нет в снапшоте (сервер, подключённый позже), всё равно откладывается, и +лимиты по-прежнему применяются поверх. Хост, который хочет, чтобы следующий +прогон сессии начинался с теми же инструментами, передаёт список в +`QueryEngineConfig.discovered_tools`. `ContextManager.called_discovered_tool_names()` +— та часть загруженных, которую прогон действительно вызывал; переносить нужно +её: поиск загружает несколько лучших совпадений, нужны они модели или нет. +Инструмент из переданного списка считается вызванным. Каждая строка снапшота +несёт `called`; строка без него считается вызванной. Строка инструмента, +загруженного в составе целой группы, несёт ещё и `group`. + +Группу целиком переносят через `QueryEngineConfig.loaded_tool_groups`: каждая +названная там группа загружается так же, как её загрузил бы +`ToolSearch(group=...)`, — только те инструменты, которые прогону можно +вызывать, одной записью под `pinned_tool_max_count`, новее инструментов, +переданных по именам, с правилами в каталоге и событием `tool_group_loaded` с +`via` `seed`. Если передать инструменты большой группы по одному, каждый станет +отдельной записью, и ограничение вытеснит остальное. `ContextManager.loaded_tool_group_names()` +— группы, которые прогон держит целиком. Инструменты переданной группы не +считаются вызванными, так что хост, переносящий только те группы, инструмент +которых прогон вызывал, отпускает неиспользованную группу через один прогон. + +### Вызов необъявленного инструмента + +Диспетчеризация проверяет политику видимости, а не объявленный список, поэтому +вызов отложенного инструмента по точному имени выполняется, как и раньше. +Теперь он ещё и **загружается**, так что со следующего запроса модель видит его +схему, а цикл эмитирует `tool_unadvertised_call`. + +Исключение — инструмент, у группы которого есть правила, ещё не данные прогону. +Такой вызов написан без схемы и без правил и действовал бы наугад ровно там, +где правила должны всё решить. Поэтому он **не выполняется**: загружается +**вся его группа**, как её загрузил бы `ToolSearch(group=...)` (допущенные +инструменты, одна запись под лимитом), правила группы отмечаются данными (сам +вызов не считается использованием инструмента — он не выполнялся), а на +вызов приходит ответ — не ошибка, ведь ничего не сломалось — с правилами, +именами остальных теперь доступных инструментов группы и строкой вызванного +инструмента: «BrowserOpen is loaded now; call it again. It takes: +BrowserOpen(url*) — …». Следующий вызов выполняется. Вся группа — потому что +работа, начатая одним её инструментом, обычно требует следующего, и модель, у +которой был загружен только вызванный, обходилась без остальных; строка — +потому что повтор по памяти повторял неверные аргументы. Второй вызов вслепую +той же группы в том же сообщении тоже ждёт и отсылает к первому ответу, а не +повторяет правила. `tool_unadvertised_call` для такого вызова несёт `executed: false` +и, в отличие от выполненного вызова, приходит до его `tool_result`, чтобы хост, +который замеряет вызовы или считает их использованием, знал: результат отвечает +на вызов, который не выполнялся. +Модели достаточно часто берут точное имя из каталога и вызывают его без +загрузки, так что отказ в вызове стоил бы им заметно; это же стоит один шаг и +только для групп с правилами. + +На имя, которое вовсе не +зарегистрировано, приходит `unknown tool: 'X'. Did you mean: A, B, C?` — до трёх +зарегистрированных имён, допущенных политикой, без учёта регистра. + +Такой вызов написан без схемы, и его аргументы — догадка. Если он падает на них, +ошибка кончается строкой инструмента в форме `ToolSearch` — +`It takes: Name(param1*, param2) — первая фраза`, — и повторная попытка верна +сразу, а не после ещё одной ошибки. «Падает на аргументах» понимается широко, +потому что инструмент, сам проверяющий аргументы, сообщает о плохом аргументе +результатом с ошибкой, а не исключением: ошибка валидации диспетчера, +исключение `TypeError`, `ValueError` (включая `ValidationError` pydantic) или +`KeyError`, либо результат с ошибкой, который инструмент считает сбоем. +Инструмент, который был в списке, этой строки не получает: его схема и так +перед моделью. Не получает её и инструмент, который отклоняет политика или +объявленный набор дочернего прогона: проверки аргументов идут до гейта, а +отклонённый инструмент никогда не «загружен». + +### Телеметрия + +- `tool_group_loaded` — `{group, via, tools}`, по разу на загрузку, которая + принесла новые инструменты группы: `via` — `search` или `select` (запрос или + имена в `ToolSearch`), `group` (загрузка целой группы), `direct_call` (вызов + вслепую) или `seed` (инструменты, с которыми хост начал прогон; объявляются + рядом с первым объявлением поверхности). `tools` — добавленные этой загрузкой + инструменты группы. +- `tool_surface_advertised` несёт `tool_groups`: каждую группу с инструментом на + предполагаемой поверхности, `{name, load, state}`, где `load` — режим, с + которым работает прогон, а `state` — `advertised`, `deferred` (отложена, + ничего не загружено) или `loaded` (отложена, часть инструментов загружена в + этот запрос). В `tool_deferral_reasons` появилось `lazy`. + +### Лавина вызовов + +`max_tool_calls_per_turn` (по умолчанию 64) ограничивает число вызовов +инструментов из одного сообщения модели. Вызовы сверх него получают по ошибке и +не выполняются, так что у каждого вызова остаётся результат и транскрипт +корректен. Они не считаются сбоем инструмента — иначе тысяча отклонённых копий +одного поиска сработала бы на нём предохранителем. Больше тысячи параллельных +вызовов в одном сообщении на практике встречалось. + +### Почему не стоит отсекать по сообщению + +`tool_retrieval_top_k` по-прежнему отсекает поверхность до инструментов, лучше +всего подходящих к последнему сообщению пользователя, но по умолчанию выключен и +не рекомендуется. Он переранжирует поверхность на каждом сообщении +пользователя, так что список инструментов — а с ним и кэшированный префикс у +провайдера — меняется вместе с сообщением. Он ранжирует слова пользователя, а +не модели: русское сообщение против английских описаний примерно в половине +случаев теряет нужный инструмент, а модель, не видящая нужного инструмента, +склонна выдумать ему имя. Модель, ищущая через `ToolSearch`, пишет запрос сама, +обычно по-английски, и находит инструмент. Вместо отсечения откладывайте +группы. + +### Схемы текстом + +Отдавать загруженный инструмент текстом в результате и вызывать через общий +`CallTool(name, arguments)` значило бы держать список инструментов неизменным. +Это не реализовано. В сравнении с загрузкой такой способ отвечал хуже на +слабых моделях, которые заполняли аргументы без ограниченного декодирования +провайдера, а экономия кэша у провайдера с кэшем по префиксу — те несколько +тысяч токенов, которые и так стоит дописывание. Сделать это правильно значило бы +ещё и переписывать каждый `CallTool` в настоящий вызов до того, как его увидят +гейт разрешений, хуки, предохранитель и предусловия, и проверять аргументы по +схеме, которую провайдер больше не применяет. --- diff --git a/docs/runtime-constants.md b/docs/runtime-constants.md index cb9e285..f562d78 100644 --- a/docs/runtime-constants.md +++ b/docs/runtime-constants.md @@ -221,6 +221,35 @@ The literal in the "wrong" example is exactly what the model exists to eliminate: the bound lives on the `max_turns_per_run` field, not in the branch. +## Knobs that are tuned together + +Most fields stand alone: one threshold, one effect.

It stops fitting in two +ways, and both are walls rather than slopes. The definitions can take enough of +the window that the conversation no longer has room, and some providers refuse a +request outright above a fixed number of tools (128 and 350 are both seen). A +host that connects a large MCP server reaches either on the first request. + +So the loop can hold whole **groups** of tools back: leave them off `tools`, +name them in one block of the system prompt, and load them on request through +`ToolSearch`. Nothing of this happens while the surface fits — unless the host +asks for it: a group declared **lazy** is held back even then, because it is a +family the run rarely needs. + +### Groups + +A tool joins a group by its class attribute `tool_group` (read with `getattr`, +like `search_hint`), or by a name prefix the host declares: + +```python +registry.declare_group("scheduling", "Timed and recurring jobs") +registry.declare_group( + "github", "GitHub issues and pull requests", dynamic=True, prefix="Mcp_Github_" +) +registry.declare_group( + "browser", + "Drive a web browser", + prefix="Browser", + load="lazy", + instructions="Ask the user before submitting a form.", +) +registry.register(ToolSearchTool(registry)) +``` + +`ToolGroup(name, description, dynamic, prefix, load, instructions)` lives in +`contracts/tool_registry.py`, and `IToolRegistry` gains `declare_group` and +`tool_groups`. `declare_group(name, description, *, dynamic=False, prefix=None, +load="auto", instructions="")` refuses a load mode outside +`TOOL_GROUP_LOADS`; redeclaring a group replaces its description, load mode and +instructions, and the loop decides again on its next request. An explicit `tool_group` wins over a prefix; among prefixes the +longest wins. Membership never reaches the wire and is not part of the surface +digest. A **dynamic** group is one whose membership is not the host's own code — +an MCP server's proxies. + +`undeclare_group(name)` forgets a group, and forgetting one that was never +declared is not an error. A host calls it when a group's tools are gone for good +— the proxies of an MCP server the operator switched off or removed — because a +declaration outlives its tools, and one left behind would claim the prefix of a +server added later under the same name. Neither declaring nor forgetting a group +changes the registry's catalogue generation: groups change no search result, and +the loop's deferral decision is keyed on the declared groups themselves. + +### Load modes + +A group's `load` says when it is advertised: + +| `load` | Held back | +|---|---| +| `eager` | never for size; only a provider's hard limit on the number of tools pushes it off | +| `auto` (default) | by the rules below: dynamic groups at once, the others while the surface is over | +| `lazy` | whenever a discovery tool is admitted for the run, whatever the size | + +`lazy` is for tool families a run rarely needs: a dozen browser tools used in +one session of a hundred cost their definitions on every request of the other +ninety-nine; held back, they cost one line of the catalogue and one call to +load. A run with no discovery tool treats `lazy` as `auto`, since a blind call +by exact name would then be the only way in, which costs more than the +definitions. A group only a tool's `tool_group` attribute names, never +declared, is `auto`. + +`eager` beats the token budget, the dynamic rule and the room kept for loaded +tools, but not `max_advertised_tools` itself: a request over the provider's +limit is refused outright, which no load mode is worth. So an eager group is +held back only while the surface is still over that limit with every other +group held back, largest eager group first. A group that becomes eager leaves +the floor of an earlier decision (see below): the operator asked for it by +name. + +`QueryEngineConfig.tool_group_loads` — a mapping of group name to load mode — +overrides the declarations for one run, and a value outside the three is +refused. A host maps operator settings and per-session exceptions through it +rather than redeclaring a group every session shares. It is part of what the +deferral decision is keyed on. + +### When groups are held back + +`tool_deferral_mode` is `"auto"` by default and `"off"` turns it off. In `auto`, +once per run — and again only if the registry's catalogue or groups, or the +host's visibility policy, change — the loop measures the surface it would +otherwise send. The policy counts because a host may switch tools on mid-run by +replacing it, registering nothing; the pins the run adds for tools it loaded do +not, so loading a tool never reopens the decision: + +1. every **lazy** group is held back, largest first, when a discovery tool is + admitted; +2. every **dynamic** group that is not eager is held back, largest first; +3. then, while the surface is over — its definitions above + `tool_definitions_ratio` of the context window, or its count above + `max_advertised_tools` with room left for `pinned_tool_max_count` loaded + tools — the other groups go, largest first, eager ones last and only while + the count is over the limit itself. + +Never held back: the forced floor (`forced_pinned`), explicitly pinned tools, +`always_load` tools, the discovery tool itself, and any tool in no group. A host +that wants a tool deferrable says so by grouping it. + +Without a discovery tool (role `discovers_tools`) registered and admitted, the +only way back for a held-back tool is a call by its exact name, so groups are +held back only when the surface is over `max_advertised_tools` — a provider +that refuses the request outright — dynamic groups first; the token budget is +not enforced then. The catalogue says to call by exact name instead of pointing +at a search the model does not have. + +Held-back tools stay **admitted** by the visibility policy: they are only not +advertised. A model that calls one by its exact name is served (see +[below](#calls-of-tools-that-were-not-advertised)). + +The decision is made once, not per request, because the catalogue it produces +sits at the head of the cached prompt: remade per request, it would move every +time the answer flipped. When a change of catalogue or policy makes it again, +the decision in force is its floor: a group held back stays held back while it +has tools, and only a dynamic group the run is newly admitted to, or a limit +the surface now exceeds, adds to it. Another session switching a server on, or +an unrelated tool switched off, leaves the catalogue as it was. + +### The catalogue + +When anything is held back, one `` block follows the skill +catalogue in the system prompt: a sentence saying the tools can be loaded at any +time and how — `ToolSearch(group="")` for a whole group, `select:` and +exact names for particular tools, or a description — a sentence saying that a +dedicated tool beats a workaround with a general one, and one line per held-back +group with its description and its **exact** tool names — or, for a group +declared by prefix with more than `tool_catalogue_max_listed_names` held-back +tools, the exact prefix and a count: + +```text +- browser: Drive a web browser. Tools: BrowserClick, BrowserOpen +- scheduling: Timed and recurring jobs. Tools: IntentCreate, ScheduleCreate + +Tools of connected servers: +- github: GitHub issues and pull requests. Tools: Mcp_Github_* (26 tools) +``` + +The host's own groups come first, and the `dynamic` groups — connected +servers — after them in a section of their own. Listed together in name order, +a dozen server lines stood ahead of the host's groups, and a model reading from +the top took them for the whole catalogue: it drove a server's browser, or a +shell, and never loaded the group made for the job. A sentence over the host's +groups naming those detours was tried too; models loaded groups more often +under it and did the task no better, so there is none. + +Exact names matter: a model that has to guess a name gets its case wrong. The +second sentence matters more than it looks — a model that cannot see a tool +reaches for the nearest one it can (a service started with a shell command, two +edits instead of one multi-edit), and that, rather than a failed search, is the +usual way a held-back tool goes unused. The block is built from the decision, each +section in name order, so it is byte-identical on every request and after a resume. When +nothing is held back and no group carries rules, no block is emitted, and the +prompt is exactly what it would be without groups. + +### Group rules + +A group may carry `instructions`: rules for using its tools — which browser to +drive, what to ask before acting. They are given once per run, where the +group's tools first come in front of the model, and never for a group the run +does not touch: + +- **In the catalogue**, for tools there from the start: a group left on the + surface, and a held-back group some of whose tools the run begins with loaded + (a host's seed, or a resumed snapshot). A held-back group's rules sit under + its line, indented; the rules of a group on the surface follow the list. A + block with rules and nothing held back has no header: + + ```text + - browser: Drive a web browser. Tools: BrowserClick, BrowserOpen + Rules for the browser tools: + Ask the user before submitting a form. + ``` + + The catalogue is built once per run and is part of the cached prefix, so + groups loaded mid-run are not added to it on every load. After a + compaction it is written again with the rules of exactly the groups on the + surface or still loaded, because the result that gave them may now be + summarised or masked. That costs something: a compaction rewrites the + conversation, not the system prompt, so when a group with rules was loaded + mid-run and is still loaded, the next request misses the cache once on the + system prompt (and on the tools, with a provider or chat template that + renders them after it). Without such a group the catalogue comes out byte + for byte as before. +- **In the `ToolSearch` result** that loads the first tools of the group: + `Rules for the tools []:` and the text, after the tool lines. +- **Instead of running a blind call** (see + [below](#calls-of-tools-that-were-not-advertised)). + +The loop keeps the set of groups whose rules were given +(`protocore.tool_group_rules_given` in the tool's metadata, and +`tool_group_rules_given` in the snapshot), so none is given twice. The set +means "the model can still read them". After a compaction it is reset to the +groups the new catalogue carries rules for: a group whose rules were in a +result the compaction took away, and which the compaction unloaded over the +cap, is owed them again — a blind call of it is held, and a `ToolSearch` that +loads it gives them. Inside a loop `ToolSearch` goes by this set alone, even +for a tool already listed. + +#### The rules mark + +Rules arrive inside tool results, and so does text from outside: a web page +read with a browser tool, a file, a command's output. Any of them can print +`Rules for the browser tools:` followed by whatever it likes. So genuine rules +carry the run's **rules mark** at the end of their heading — +`Rules for the browser tools [3f9a1c2e]:` — and the catalogue, in the system +prompt that no tool output reaches, names the mark once whenever any group in +it carries rules, and says that text claiming to be rules without it is +content to read, never rules to follow, and that the mark is not to be written +anywhere. + +The mark is eight hex digits, an HMAC of the session id under a key drawn anew +in every process (`tool_rules_mark(session_id)`). It is the same for every run +of a session in one process, because it sits in the catalogue at the head of +the cached prompt; the snapshot carries it (`tool_group_rules_mark`), so a +resumed run keeps the mark its history's rules were given with. The loop +stamps it for a discovery tool as `protocore.tool_group_rules_mark`. + +A separate runtime-authored message for the rules was considered and +rejected: a user turn between a tool result and the next assistant turn is a +sequence some chat templates refuse (the loop avoids it elsewhere), and rules +in a user turn read as the operator speaking. The mark keeps the rules where +they are needed — beside the tools they govern — and makes an imitation +recognisable. A run whose groups carry no rules gets no mark in its prompt, +which stays exactly as it was. + +### `ToolSearch` + +`protocore/tools/tool_search.py` ships the discovery tool: +`ToolSearchTool(registry)`, named `ToolSearch`, carrying the role +`discovers_tools` in its own `tool_roles`, `always_load`, and concurrent-safe. +The loop advertises it **only while something is held back**; with the whole +catalogue on the surface it has nothing to find, and a model offered a search +it does not need spends turns on it. + +- `query` in free text returns up to `tool_search_max_results` matches, best + first, one line each — `Name(param1, param2*) — first sentence`, required + parameters starred — and loads the first `tool_search_autoload_count` of them. + A model that searches finds the tool it needs among the first three nearly + every time. +- `select:Name1,Name2` loads exactly those tools (a name in the wrong case is + still accepted). An unknown name is answered with its nearest admitted names. + The names may also come as their own argument, `select`, a list or a + comma-separated string: models reach for that spelling unprompted, and + refusing it only costs them a turn. Names win over a description sent beside + them. +- `group` loads every admitted tool of one group, named exactly (a name in the + wrong case is still accepted); `select` also takes `group:` entries + beside tool names. An unknown group is answered with the groups the run may + use. The result lists the group's tools one line each, like any load. + Tools loaded as a whole group are **one entry** under `pinned_tool_max_count` + and are unloaded together: a model that asked for a group cannot notice that + eviction left half of it, and a group of twelve against a cap of fifteen + would otherwise crowd out everything else. +- The first tools of a group with rules that a call loads bring the rules, once + (see [Group rules](#group-rules)). +- The first lines of the result say which tools are now loaded and callable, + and, apart from those, which of the requested or matched tools were **already + in the tool list**. The loop tells the tool what the calling request + advertised (`ADVERTISED_TOOLS_METADATA_KEY`, stamped after the operator's + envelope is merged so it cannot be forged). Reporting a tool the model had + all along as "Loaded" misleads: a model asked to use a skill searched for it, + was told "Loaded: WebSearch", took the skill for loaded and never opened it. + The description says so too — the tool loads tools only, and a skill is not + one. +- The live visibility policy is read from `ToolContext.metadata` + (`TOOL_VISIBILITY_POLICY_METADATA_KEY`, `protocore.tool_visibility_policy`), + and a child run's declared tool set beside it (`TOOL_ALLOWLIST_METADATA_KEY`), + so the search never lists, suggests or loads a tool the dispatch gate would + refuse, and a blocked name is never offered as "close". The dispatcher + assigns both on every call rather than setting them when absent, so a value + already in the bag never stands in for the one the gate enforces. With no + policy in the bag the search admits nothing. + +The tool only ranks and reports. It names what it loaded under +`TOOLS_LOADED_METADATA_KEY` in its result's metadata — and the groups it loaded +whole under `TOOL_GROUPS_LOADED_METADATA_KEY`, the groups whose rules it gave +under `TOOL_GROUP_RULES_METADATA_KEY` — and the loop — which owns +the surface — loads them, believing that key only from a tool in the +`discovers_tools` role and only for names the policy (and a child's declared +tool set) admits. The tunables are read off the run's constants on +`ToolContext.run_state.rc`; an engine built without a host run state carries its +own constants there. + +### Discovery order and the prompt cache + +Loaded tools are **appended** to the end of the advertised list, in the order +they were discovered, and stay there. The base surface stays name-sorted and +does not move when a tool is loaded, and a loaded tool does not move when +another one is, so a prefix-caching provider re-reads only the tail: one loaded +schema costs on the order of a couple of thousand uncached tokens, not the whole +prefix. A tool the run searched for that is already on the surface is not loaded +again. + +The run keeps loaded tools in discovery order with each one's last use +(`ContextManager.discover_tool`, `note_tool_used`). `pinned_tool_max_count` caps +them, but the cap is applied — least recently used first — only where the prompt +prefix starts over anyway: after compaction, at a turn boundary (`rearm`), and +when a run starts. Unloading a tool in the middle of a run would pull a schema +out from under a model that may be about to call it, and would cost the cache +exactly what the cap exists to save. The one exception is a provider limit: +when base plus loaded tools would exceed `max_advertised_tools`, the least +recently used loaded tools are left off that request (they stay loaded). + +The loaded tools and the held-back groups travel in the snapshot +(`discovered_tools`, `deferred_tool_groups`), and a resumed run keeps the +decision instead of measuring again — as a floor: a dynamic group the snapshot +does not name (a server that connected since) is still held back, and the +limits are still enforced on top. A host that wants the next run of a session +to start with the same tools passes a list as `QueryEngineConfig.discovered_tools`. +`ContextManager.called_discovered_tool_names()` is the part of the loaded tools +the run actually called, and is the list to carry: a search loads its best few +matches whether or not the model wanted them. A seeded tool counts as called. +Each snapshot row carries `called`; a row without it is taken as called. A row +of a tool loaded as part of a whole group also carries `group`. + +A group is carried whole with `QueryEngineConfig.loaded_tool_groups`: each group +named there is loaded as `ToolSearch(group=...)` would load it — only the tools +the run may call, one entry under `pinned_tool_max_count`, newer than the tools +seeded by name, its rules in the catalogue, announced as `tool_group_loaded` with +`via` `seed`. Passing a large group's tools one by one instead makes each of them +an entry, and the cap then pushes out the rest of the seed. +`ContextManager.loaded_tool_group_names()` is the groups the run holds whole. A +seeded group's tools do not count as called, so a host that carries only the +groups a run also called a tool of lets an unused group go after one run. + +### Calls of tools that were not advertised + +Dispatch checks the visibility policy, not the advertised list, so a call of a +held-back tool by its exact name is served, as it always was. It is also +**loaded**, so its schema is in front of the model from the next request, and +the loop emits `tool_unadvertised_call`. + +The one exception is a tool whose group carries rules the run has not been +given. A call of it was written without the schema and without the rules, and +it would act on a guess about exactly what the rules are there to settle. So it +is **not run**: its **whole group** is loaded, as `ToolSearch(group=...)` would +load it (the tools the run may call, one entry under the cap), the group's +rules are marked given (the call itself is not counted as a use of the tool, +since it did not run), and the call is answered — not as an error, since +nothing failed — with the rules, the names of the group's other tools now +callable, and the called tool's line: "BrowserOpen is loaded now; call it +again. It takes: BrowserOpen(url*) — …". The next call runs. The whole group, +because a job that starts with one of its tools usually needs another next, +and a model that had only the one it called went on without the rest; the +line, because a retry written from memory repeated the wrong arguments. A +second blind call of the same group in the same message waits too, and is +pointed at the first answer rather than given the rules twice. `tool_unadvertised_call` +carries `executed: false` for such a call and, unlike for a call that ran, +comes before the call's `tool_result`, so a host that times calls or counts +them as used knows the result answers a call that never ran. Models read an exact name from the +catalogue and call it without loading it often enough that refusing the call +outright would cost them; this costs one step, and only for groups with rules. + +A name that is not registered at all is +answered with `unknown tool: 'X'. Did you mean: A, B, C?` — up to three +registered names the policy admits, compared case-insensitively. + +A call made that way was written without the schema, and its arguments are a +guess. When it fails on them, the error ends with the tool's line in the +`ToolSearch` form — `It takes: Name(param1*, param2) — first sentence` — so the +retry is right the first time instead of after one more failure. "Fails on its +arguments" is read broadly, because a tool that checks its own arguments reports +a bad one as an error result, not an exception: a dispatch validation error, an +exception that is a `TypeError`, `ValueError` (which includes a pydantic +`ValidationError`) or `KeyError`, or an error result the tool counts as a +failure. A tool that was on the list never gets the line; its schema is already +in front of the model. Nor does a tool the policy or the child's declared set +refuses: the argument checks run before the gate, and a refused tool is never +"loaded now". + +### Telemetry + +- `tool_group_loaded` — `{group, via, tools}`, once per load that brought new + tools of a group: `via` is `search` or `select` (a `ToolSearch` query or + names), `group` (a whole-group load), `direct_call` (a blind call) or `seed` + (the tools a host started the run with, announced beside the first + advertisement). `tools` are the tools of the group that load added. +- `tool_surface_advertised` carries `tool_groups`: every group with a tool on + the would-be surface, `{name, load, state}`, where `load` is the mode the run + uses and `state` is `advertised`, `deferred` (held back, none of it loaded) or + `loaded` (held back, some of its tools loaded onto this request). + `tool_deferral_reasons` gains `lazy`. + +### A runaway batch + +`max_tool_calls_per_turn` (default 64) bounds the tool calls dispatched from one +model message. The calls past it are each answered with an error and never run, +so every call still has its result and the transcript stays valid. They do not +count as the tool failing — a thousand refused copies of one search would +otherwise trip the circuit breaker on it. More than a thousand parallel calls in +one message has been seen in practice. + +### Why per-message clipping is discouraged + +`tool_retrieval_top_k` still clips the surface to the tools that best match the +latest user message, but it is off by default and not recommended. It re-ranks +the surface on every user message, so the tool list — and with it the provider's +cached prefix — changes whenever the message does. It ranks the user's words, +not the model's: a Russian message against English descriptions leaves the right +tool out about half the time, and a model that cannot see the tool it needs +tends to invent a name for it. A model searching with `ToolSearch` writes its own +query, usually in English, and finds the tool. Hold groups back instead. + +### Schemas as text + +Delivering a loaded tool as text in a result, called through a generic +`CallTool(name, arguments)`, would keep the tool list constant. It is not +implemented. Measured against loading, it answered worse on weaker models, which +filled arguments without the provider's constrained decoding, and the cache it +saves on a prefix-caching provider is the few thousand tokens appending already +costs. Doing it properly would also mean rewriting each `CallTool` into the real +call before the permission gate, hooks, circuit breaker and preconditions see +it, and validating arguments against a schema the provider no longer enforces. --- diff --git a/protocore/__init__.py b/protocore/__init__.py index 0e7918b..017439d 100644 --- a/protocore/__init__.py +++ b/protocore/__init__.py @@ -20,7 +20,7 @@ - :mod:`protocore.runtime.context.budgets.derive_budgets` - :mod:`protocore.runtime.wire_format` compaction placeholders - :mod:`protocore.runtime.chain_parser` shell-grammar parser - - :mod:`protocore.runtime.tool_retrieval` BM25 multilingual retrieval + - :mod:`protocore.runtime.tool_retrieval` BM25F multilingual tool retrieval Loop machinery (QueryEngine + query()) is available in :mod:`protocore.runtime.query_engine`.

A host that connects a large +MCP server reaches either wall on the first request. + +So a host may sort its catalogue into GROUPS +(:class:`~protocore.contracts.tool_registry.ToolGroup`), and when the surface +is over, whole groups are held back: left off ``tools``, named one line each +in a catalogue in the system prompt, and loaded on request through a +discovery tool (the core's is :class:`~protocore.tools.tool_search.ToolSearchTool`). +A loaded tool is APPENDED to the surface in the order it was discovered, so +what came before it — the name-sorted base surface and every earlier load — +keeps its bytes, and a prefix-caching provider re-reads only the tail. + +The decision is made once per run. When the catalogue or the policy changes +it is made again on top of itself: what is held back stays held back, and only +a newly admitted dynamic group or a limit now exceeded adds to it. Deciding +afresh would move the catalogue in the middle of the cached prefix every time +the answer flipped, which is worse than either answer. +Held-back tools stay admitted by the visibility policy: a model that calls one +by its exact name is served, and the tool is loaded for the rest of the run. + +A group may also be held back by choice. Its load mode — the declaration's, +or the run's own override — is ``auto`` for the rule above, ``lazy`` for a +family the run rarely needs, held back whenever there is a discovery tool to +load it, and ``eager`` for one that stays on the surface whatever the size, +giving way only to a provider's hard limit on the number of tools. And a group +may carry rules for its tools, given once per run where the tools first come +in front of the model: in the catalogue for tools there from the start, in the +result that loads them, or instead of running a call made to one blind. + +Nothing here runs when nothing is over. No group declared, no discovery tool +registered, or a surface inside both limits, with no group lazy and none +carrying rules: the surface and the system prompt are exactly what they would +be without this module. +""" +from __future__ import annotations + +import hashlib +import hmac +import secrets +from collections.abc import Callable, Iterable, Mapping, Sequence +from dataclasses import dataclass, replace +from typing import TYPE_CHECKING, Any, Final + +from protocore.contracts.runtime_constants import LoopConstants +from protocore.contracts.tool_registry import ( + TOOL_GROUP_LOADS, + TOOL_GROUP_RULES_METADATA_KEY, + TOOL_GROUPS_LOADED_METADATA_KEY, + TOOLS_LOADED_METADATA_KEY, + ToolGroup, + ToolVisibilityPolicy, + group_rules_text, + policy_admits, + tool_group_of, +) +from protocore.contracts.tool_retrieval import RetrievalSettings +from protocore.contracts.tool_roles import ToolRole, ToolRoleMap +from protocore.contracts.tools import Tool +from protocore.contracts.types import ToolCall, ToolDefinition +from protocore.runtime.context.budgets import derive_budgets +from protocore.runtime.events import EventType, TurnEvent +from protocore.runtime.token_counting import estimate_tokens +from protocore.runtime.tool_retrieval import tool_line + +if TYPE_CHECKING: + from protocore.runtime.query_engine import QueryEngine + from protocore.runtime.tool_dispatch import DispatchOutcome + +#: How the tools of a group came to be loaded, as ``tool_group_loaded`` says. +#: ``search`` and ``select`` are a discovery tool's two forms, ``group`` its +#: whole-group form, ``direct_call`` a call of a tool that was not advertised, +#: and ``seed`` the tools a host started the run with. +GROUP_LOAD_VIAS: Final[tuple[str, ...]] = ("search", "select", "group", "direct_call", "seed") + +__all__ = [ + "GROUP_LOAD_VIAS", + "NO_DEFERRAL", + "ToolDeferral", + "build_tool_surface", + "calls_held_for_rules", + "discovery_tool_names", + "ensure_tool_deferral", + "held_call_text", + "hold_call_for_rules", + "note_prompt_prefix_restarted", + "observe_dispatched_tool", + "plan_tool_deferral", + "render_tool_catalogue", + "seed_group_events", + "seed_tool_groups", + "tool_catalogue_block", + "tool_group_states", + "tool_rules_mark", +] + +#: The sentence under the catalogue.
