fix(hook): treat configured installs without prefs.json as returning users#1152
Conversation
…users
is_first_time() in the keyword-detector UserPromptSubmit hook treats a
missing ~/.ouroboros/prefs.json as a genuine first run, so the welcome
skill-suggestion is injected on every keyword-less prompt (and every
/ouroboros:* command). welcomeCompleted/welcomeShown are only written by
the skippable welcome flow, so a user who ran `ooo setup` (registering the
MCP server, writing config.yaml/credentials.yaml/ouroboros.db) but skipped
the welcome has no prefs.json and is re-nagged forever, across sessions.
Add _has_prior_install_state(): when prefs.json is absent, fall back to
concrete install signals (~/.ouroboros/{config.yaml,credentials.yaml,
ouroboros.db} or an MCP registration) before declaring a first run. A
pristine home still reports first-time, so genuinely new users keep the
welcome experience.
This completes the prefs-migration fix from Q00#663 for the case where
prefs.json was never created at all.
Relates to Q00#659

LGTM — approving. Two non-blocking nits below; happy to merge as-is or fold them in here. Heuristic is well-grounded. I traced each marker to its writer to confirm the discriminator is reliable:
Each of these only appears once real setup or runtime work has happened, so Nit 1 (non-blocking): malformed-prefs asymmetry. The PR's thesis is "install markers override a missing Nit 2 (non-blocking): exception-handling contract. Re: the prior approval — the Roadmap note: this is outside the AgentOS Track A/B/C scope tracked in #961 — pure plugin-onboarding hook fix — so no tier-gate sequencing applies. Thanks for the careful root-cause writeup and the red→green verification. Approving; let me know if you'd like to address the nits in this PR or in a follow-up and I'll merge accordingly. |

Address review nits from Q00#1152: - Add test_malformed_prefs_stays_first_time_despite_install_markers: a malformed prefs.json (parses to a non-dict) stays first-time even when install markers exist, pinning the intentional asymmetry vs. the missing-prefs branch so a future reader does not "fix" it by routing the malformed branch through _has_prior_install_state(). - Comment that branch in is_first_time() to document the asymmetry inline. - Note in _has_prior_install_state()'s docstring that it has no try/except of its own and relies on is_first_time()'s fail-open handler. No behavior change -- comments, docstring, and one regression test only. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Thanks for the careful re-review — folded both nits into Nit 1 (malformed-prefs asymmetry): did both (a) and (b) — the comment explains the intent, the test makes it enforceable so a future refactor can't silently drop it:
Nit 2 (exception-handling contract): added a docstring paragraph to No behavior change — comments, docstring, and one regression test only. |

Issue #659 Requirements
| Requirement | Status |
|---|---|
Existing valid prefs without welcomeCompleted must not nag forever. |
MET — scripts/keyword-detector.py:213 accepts welcomeCompleted/welcomeShown, and scripts/keyword-detector.py:215 treats any non-empty valid prefs as returning-user state; covered by tests/unit/scripts/test_keyword_detector.py:33 and tests/unit/scripts/test_keyword_detector.py:41. |
/ouroboros:welcome --skip must write the key consumed by the detector. |
MET — skills/welcome/SKILL.md:82 merges both welcomeShown and welcomeCompleted without deleting existing keys. |
| Setup/seed star prompt must not overwrite welcome prefs. | MET — skills/setup/SKILL.md:88 and skills/setup/SKILL.md:92 require merge/preserve behavior; skills/seed/SKILL.md:388 and skills/seed/SKILL.md:392 do the same. |
Configured installs with missing prefs.json must not be treated as first-time forever. |
MET — scripts/keyword-detector.py:203 falls back to _has_prior_install_state(), which checks install markers and MCP registration at scripts/keyword-detector.py:184; covered by tests/unit/scripts/test_keyword_detector.py:49, tests/unit/scripts/test_keyword_detector.py:61, and tests/unit/scripts/test_keyword_detector.py:71. |
| Pristine homes must still receive first-run welcome. | MET — absent prefs plus no install markers returns first-time through scripts/keyword-detector.py:203; covered by tests/unit/scripts/test_keyword_detector.py:80. |

Why this is merge-safe
-
Heuristic is grounded, not fanciful. Each install marker was traced to its writer in the previous review pass:
config.yaml/credentials.yaml→create_default_config()insrc/ouroboros/config/loader.py, only on theooo setuppath.ouroboros.db→ SQLite event store (src/ouroboros/persistence/event_store.py) + brownfield store (src/ouroboros/persistence/brownfield.py), default~/.ouroboros/ouroboros.db.- MCP registration →
is_mcp_configured()already in this module.
None of these appear in a pristine home, so the discriminator cannot mis-classify a true first-run, andtest_pristine_home_is_still_first_timelocks that contract in.
-
Intentional asymmetry is now load-bearing, not accidental. The
not isinstance(prefs, dict)branch deliberately does not route through_has_prior_install_state(): a corrupt prefs file is a stronger signal than orphan markers, and re-running welcome rewrites it cleanly.e55aebaaadds both an inline comment and a regression test (test_malformed_prefs_stays_first_time_despite_install_markers) so a future refactor cannot silently "fix" this into a regression. -
Exception contract is now documented.
_has_prior_install_state()deliberately has notry/exceptof its own — exceptions propagate tois_first_time()'s outer handler, which fails open to first-time (safe direction: a transient stat error surfaces the welcome rather than suppressing it). The docstring now states this explicitly. -
Test coverage is targeted and proportional. Six new tests pin all behavior changes:
test_missing_prefs_but_config_yaml_marks_not_first_timetest_missing_prefs_but_db_marks_not_first_timetest_missing_prefs_but_mcp_registered_marks_not_first_timetest_pristine_home_is_still_first_time(regression guard for the discriminator)test_malformed_prefs_stays_first_time_despite_install_markers(asymmetry guard)- plus existing
test_missing_prefs_file_is_first_timeis preserved unchanged.
-
Not over-engineered. The helper is 15 lines of body, the wire-up is a single line, and the four marker checks are each independently justified (different setup paths leave different traces). No new abstractions, no new state, no new config surface, no new dependencies. I considered whether the markers could be collapsed to just
ouroboros.db; they can't — a config-only setup or MCP-only registration leaves no DB. -
Outside the AgentOS roadmap. Re-checked against the Meta SSOT: AgentOS roadmap sequencing (#920–#960) #961 SSOT and the AgentOS-roadmap-warden tracks: this is a plugin-onboarding hook fix touching only
scripts/keyword-detector.pyand its tests. It is not a Track A (ooo runfat-harness), Track B (ooo autoself-healing), or Track C (AgentOS substrate dump Agent OS roadmap: makeooo runtrustworthy with a fat harness execution path #920–Agent OS HITL: standardize WAIT/RESUME ask-user and approval contract #960) deliverable, and no tier-gate sequencing applies. It is correctly flagged as such in the bot review. -
CI is fully green on the final commit. All 8 checks pass on
e55aebaa: Ruff Lint, MyPy Type Check, Bridge TypeScript, Test Py 3.12 / 3.13 / 3.14,enforce-boundary,enforce-envelope. I also re-ranuv run pytest tests/unit/scripts/test_keyword_detector.pyandruff checklocally one55aebaain an isolated worktree — 40 passed, ruff clean.
Verdict
Approving for merge. The fix is minimal, well-scoped, fully tested, documented, outside the roadmap-sequencing gates, and has both human and bot approval on the final HEAD with all CI green. Ready to merge.

What Improved
- Added
_has_prior_install_state()so configured installs withoutprefs.jsonare treated as returning users instead of receiving the welcome suggestion indefinitely. - Added focused regression coverage for config marker, DB marker, MCP registration, pristine-home behavior, and malformed-prefs asymmetry.
- Preserved adjacent welcome/setup/seed prefs contracts: skip writes
welcomeCompleted, and setup/seed mergestar_askedwithout deleting welcome keys.
Issue #659 Requirements
| Requirement | Status |
|---|---|
Existing valid prefs without welcomeCompleted must not nag forever. |
MET — scripts/keyword-detector.py:213 accepts welcomeCompleted or legacy welcomeShown, and scripts/keyword-detector.py:215 treats other non-empty valid prefs as returning-user state; tests at tests/unit/scripts/test_keyword_detector.py:33 and :41. |

Test Coverage
Targeted coverage is adequate. tests/unit/scripts/test_keyword_detector.py:49, :61, and :71 cover the three new missing-prefs returning-user signals; :80 preserves pristine first-run behavior; :87 pins the malformed-prefs asymmetry. Existing prefs compatibility is covered at tests/unit/scripts/test_keyword_detector.py:25, :33, and :41. I ran SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 uv run pytest tests/unit/scripts/test_keyword_detector.py -q because the artifact checkout has broken VCS metadata; result: 40 passed. I also ran SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 uv run ruff check scripts/keyword-detector.py tests/unit/scripts/test_keyword_detector.py; result: all checks passed. All newly added logic has corresponding tests.
Design / Roadmap Gate
Aligned. design_context.md:12 through :20 identifies #659 as the relevant design signal, and design_context.md:68 through :75 shows no separate roadmap gate beyond advisory AgentOS context. Current HEAD evidence is confined to scripts/keyword-detector.py and tests/unit/scripts/test_keyword_detector.py; it does not alter AgentOS runtime, persistence schema, workflow, or public API contracts.

Summary
scripts/keyword-detector.pyinjects the welcome<skill-suggestion>block onevery keyword-less prompt (and every
/ouroboros:*slash command) whileis_first_time()returnsTrue.is_first_time()treats a missing~/.ouroboros/prefs.jsonas a genuine first run — but a fully-configured user canlegitimately have no
prefs.json, so the welcome suggestion fires forever, acrossevery session.
This is the same class of bug as #659 (fixed in #663), for the sub-case #663 did
not cover:
prefs.jsonnever created at all, rather than created withoutwelcomeCompleted.Impact
welcomeCompleted/welcomeShownare only written by the (skippable) welcomeflow. A user who ran
ooo setup— which registers the MCP server and writes~/.ouroboros/config.yaml,credentials.yaml, andouroboros.db— but skippedthe welcome has no
prefs.json, so:/ouroboros:*command (no natural-language keyword match) gets it too;Observed in the wild:
~/.ouroboros/fully populated (config.yaml,credentials.yaml,ouroboros.db,mcp-server.pid) withouroborosregisteredin
~/.claude/mcp.json, but noprefs.json— the nag fired on every prompt.Root cause
#659 itself suggested an
ouroboros.dbheuristic as one option; #663 took thelighter
welcomeShown+not bool(prefs)migration, which only helps whenprefs.jsonalready exists.Fix
Add
_has_prior_install_state(). Whenprefs.jsonis absent, consult concreteinstall signals before declaring a first run:
~/.ouroboros/config.yaml,credentials.yaml, orouroboros.dbexists, oris_mcp_configured()).A pristine home still returns
True, so genuinely new users still get thewelcome experience; the existing
test_missing_prefs_file_is_first_timeispreserved unchanged.
Testing
4 new cases in
TestFirstTimePrefs(tests/unit/scripts/test_keyword_detector.py):config.yaml / ouroboros.db / MCP-registered → not first-time; pristine home →
still first-time (regression guard).
Verified red→green: the three "configured" tests fail on
mainand pass withthis change.
Relates to #659.
