just updated console messages +- Updated two console message locations in `plan.ts`: success message (line 229) and warning message (line 236) +- Removed unused `join` import from `node:path` since we no longer construct the todoDir path locally +- No plan-specific tests exist (`src/**/*plan*.test.ts`), so relied on typecheck and existing test suite to verify changes + +## update-status-command + +- Simple change: imported `getTodoDir` from paths module and passed it to `readTasks()` +- The `readTasks()` function already accepts an optional `todoDir` parameter with a default of `join(process.cwd(), "todo")` -

this change only affects the default when no parameter is passed +- No tasks-specific tests exist in `src/tasks.test.ts` - tests are in the later `add-paths-tests` task +- Existing tests (loop.test.ts, commands/init.test.ts) pass because they already create `.math/todo/` structure from previous migrations +- Pre-existing test failures in `ui/app.test.ts` are unrelated -

creates more meaningful backup names like `core-infrastructure/` instead of `todo-1-16-2026/` +- Backups now go to `.math/backups//` instead of project root - keeps project root clean +- Added `migrateIfNeeded()` call at start - ensures legacy `todo/` users are prompted to migrate before the command runs +- Added `mkdir(backupsDir, { recursive: true })` to ensure `.math/backups/` exists before copying +- Updated all console messages to reference `.math/todo/` and `.math/backups/` paths +- Imported `mkdir` from `node:fs/promises` for async directory creation +- Counter-based naming still works for duplicate summaries (e.g., `core-infrastructure`, `core-infrastructure-1`, `core-infrastructure-2`) + +## update-prune-module + +- Simplified `findArtifacts()` by removing the `directory` parameter - it now always scans `.math/backups/` using `getBackupsDir()` from paths module +- Removed `BACKUP_DIR_PATTERN` regex entirely since we no longer need to distinguish backup directories by name pattern - anything in `.math/backups/` is an artifact +- This is a breaking change for the test file which still passes directory parameter - `update-existing-tests` task will fix those tests +- The change makes the module simpler: no pattern matching needed, just list all subdirectories of `.math/backups/` +- Verified the implementation works manually by creating test directories in `.math/backups/` and running `findArtifacts()` +- The prune command (`src/commands/prune.ts`) already calls `findArtifacts()` without arguments, so no changes needed there + +## update-prune-command + +- Verified that `src/commands/prune.ts` already correctly uses the updated prune module - no code changes were needed +- The command imports `findArtifacts`, `confirmPrune`, `deleteArtifacts` from `../prune` and calls them correctly +- Since `findArtifacts()` now internally uses `getBackupsDir()`, the command automatically targets only `.math/backups/` contents +- The test file `src/prune.test.ts` has failing tests because it still passes a directory argument to `findArtifacts()` - this is expected and will be fixed in the `update-existing-tests` task +- Pattern: when a module's API changes (like removing a parameter), the consuming code may not need updates if it was already using the simpler form of the API + +## update-templates + +- Added "Directory Structure" section to PROMPT_TEMPLATE Quick Reference documenting `.math/todo/` and `.math/backups//` paths +- Relative references to TASKS.md and LEARNINGS.md within the template don't need path prefixes - the template is placed in `.math/todo/` so relative references work correctly +- No template-specific tests exist in the codebase, and this is a documentation-only change, so no new tests were required +- Pre-existing test failures in `src/prune.test.ts` are from `update-prune-module` task changing the `findArtifacts()` function signature -

good coverage for a simple module +- Pattern: when verifying path modules, test both exact values AND structural properties (is absolute, has correct parent-child relationships) +- Task was effectively a verification task - confirmed existing tests are sufficient and passing + +## add-migration-tests + +- Expanded existing `src/migration.test.ts` from 7 to 14 tests covering the four areas specified in the task +- Testing interactive readline prompts is complex in bun:test - workaround was to test the file-moving behavior by directly calling fs operations (simulating what `performMigration` does internally) +- Added tests for: legacy directory with multiple files detection, non-matching files in legacy directory, file content preservation after migration, and new directory detection independence from file contents +- Pattern: when you can't mock internal functions easily, test the behavior at the integration boundary by replicating what the internal function does and verifying pre/post conditions +- Pre-existing test failures in `src/prune.test.ts` are unrelated - caused by `findArtifacts()` signature change in `update-prune-module` task, will be fixed in `update-existing-tests` task + +## add-summary-tests + +- Tests already existed in `src/summary.test.ts` with comprehensive coverage (8 tests, 8 expect() calls) - likely created during `add-summary-generator` implementation +- Existing tests cover all key scenarios: phase name extraction, max 5 words truncation, task ID fallback, special characters handling, ultimate "plan" fallback, empty content, multiple phases (first one used), and numbers in phase names +- All tests pass - no additional tests needed as the coverage is already comprehensive +- Pattern: when implementing a module (like `add-summary-generator`), it's valuable to write tests alongside the implementation rather than deferring to a separate test task - this leads to better coverage and faster feedback loops +- Pre-existing test failures in `src/prune.test.ts` are unrelated - will be fixed in `update-existing-tests` task + +## update-existing-tests + +- Only `src/prune.test.ts` needed updates - `loop.test.ts` and other test files were already updated during earlier tasks +- Key changes to prune tests: + 1. Tests now create directories in `.math/backups/` instead of directly in `TEST_DIR` + 2. `findArtifacts()` now takes no arguments - it always looks in `.math/backups/` via `getBackupsDir()` + 3. Updated backup directory names from date-based (`todo-1-15-2025`) to summary-based (`core-infrastructure`) to match new naming convention +- Required adding `process.chdir(TEST_DIR)` in `beforeEach` so the paths module resolves `.math/backups/` correctly relative to the test directory +- Updated 7 test cases to reflect the new API and directory structure while preserving test intent (empty dir, find dirs, numeric suffixes, ignore files, non-existent dir, absolute paths) +- Test count increased from 10 to 15 tests due to clearer test separation and the new directory structure requirements + +## validate-full-workflow + +- All 95 tests pass with 217 expect() calls - solid test coverage for the migration +- Manual validation of all 6 commands confirmed full workflow works with `.math/` directory structure: + - `math init`: Creates `.math/todo/` with PROMPT.md, TASKS.md, LEARNINGS.md ✓ + - `math status`: Reads tasks from `.math/todo/TASKS.md` correctly ✓ + - `math plan`: Prompts for user input and works with `.math/todo/` structure ✓ + - `math run --dry-run`: Starts agent loop, reads files from `.math/todo/` ✓ + - `math iterate`: Backs up to `.math/backups//` and resets files ✓ + - `math prune`: Finds and deletes backups from `.math/backups/` only ✓ +- Migration from legacy `todo/` to `.math/todo/` works correctly - prompts user, moves files, removes old directory +- Help text (`math --help`) correctly references `.math/` paths throughout +- The migration is seamless for existing users - they get prompted once, then everything just works diff --git a/todo/PROMPT.md b/.math/backups/core-infrastructure/PROMPT.md similarity index 93% rename from todo/PROMPT.md rename to .math/backups/core-infrastructure/PROMPT.md index 961243b..f069a9e 100644 --- a/todo/PROMPT.md +++ b/.math/backups/core-infrastructure/PROMPT.md @@ -97,12 +97,17 @@ Only commit AFTER tests pass. | Action | Command | |--------|---------| | Run tests | `bun test` | +| Run single test | `bun test src/path.test.ts` | | Type check | `bun run typecheck` | | Run CLI | `bun index.ts ` | | Add changeset | `bunx changeset` | | Stage all | `git add -A` | | Commit | `git commit -m "feat: ..."` | +**Directory Structure:** +- `.math/todo/` - Active sprint files (PROMPT.md, TASKS.md, LEARNINGS.md) +- `.math/backups//` - Archived sprints from `math iterate` + --- ## Remember diff --git a/.math/backups/core-infrastructure/TASKS.md b/.math/backups/core-infrastructure/TASKS.md new file mode 100644 index 0000000..3b6d547 --- /dev/null +++ b/.math/backups/core-infrastructure/TASKS.md @@ -0,0 +1,153 @@ +# Project Tasks + +Task tracker for multi-agent development. +Each agent picks the next pending task, implements it, and marks it complete. + +## How to Use + +1.

-
-## mock-loop-interface
-
-- Created `src/agent.ts` with an `Agent` interface that defines `run()` and `isAvailable()` methods
-- The interface uses typed events (`onLog`, `onOutput`) for streaming updates to consumers
-- `LogEntry` has categories: info, success, warning, error - matches the existing loop.ts color scheme
-- `AgentOutput` is raw text with timestamps for agent stdout/stderr
-- `OpenCodeAgent` wraps the real CLI using `Bun.spawn()` to capture output streams
-- `MockAgent` is fully configurable: logs, output, exitCode, delay, and availability
-- For tests, use `!` non-null assertions when accessing array elements after verifying length with `toHaveLength()`
-- The mock can be reconfigured mid-test using `configure()` method for testing different scenarios
-- Keep test mocks simple - just arrays of strings and basic config objects, no complex simulation
-
-## loop-dry-run
-
-- Added `dryRun` and `agent` options to `LoopOptions` interface
-- When `dryRun: true`, the loop skips git branch creation and uses MockAgent instead of OpenCodeAgent
-- The `agent` option allows injecting any Agent implementation for testing or custom behavior
-- Replaced `process.exit(1)` calls with `throw new Error()` for better testability
-- Tests need `pauseSeconds: 0` to avoid the 3-second default pause between iterations
-- TASKS.md format uses `###` (h3) for task IDs, not `##` (h2) - important for test fixtures
-- When testing agent invocation, need pending tasks - if all tasks complete, loop exits before calling agent
-- Event callbacks (onLog, onOutput) forward agent events to the loop's console.log and stdout
-
-## output-buffer
-
-- Created `src/ui/buffer.ts` as a shared module for storing loop logs and agent output separately
-- Reused the `LogCategory` type from `src/agent.ts` to keep categories consistent (info, success, warning, error)
-- Used callback-based subscriptions with `Set` for efficient add/remove operations
-- Subscription functions return an unsubscribe function (closure pattern) for clean cleanup
-- `getLogs()` and `getOutput()` return copies of arrays (`[...array]`) to prevent external mutation
-- The `clear()` method was added for buffer reset while keeping subscriptions intact
-- Tests verify that subscriptions continue working after clear() - important for reconnection scenarios
-- Kept the module simple with no dependencies beyond the LogCategory type - YAGNI principle
-
-## stream-capture
-
-- Added `buffer?: OutputBuffer` to `LoopOptions` - optional so non-UI mode continues to work unchanged
-- Used a factory function pattern `createLoggers(buffer?)` to create log functions that write to both console and buffer
-- The loggers are created at the start of `runLoop` and passed to `createWorkingBranch` via a `Loggers` interface
-- Agent output is captured in the `onOutput` event handler: writes to both `process.stdout` and `buffer?.appendOutput()`
-- The optional chaining (`buffer?.appendLog`) ensures graceful fallback when no buffer is provided
-- Console.log calls continue working for non-UI mode - the buffer is purely additive
-- Tests mock both `console.log` and `process.stdout.write` to verify output goes to both destinations
-- Buffer subscriptions work in real-time - subscribers receive entries as they are appended during loop execution
-
-## bun-server
-
-- Bun.serve() returns a server object with inferred type - no need to import `Server` type explicitly (it requires a generic argument anyway)
-- For WebSocket upgrade, use `server.upgrade(req, { data })` inside fetch handler - if successful returns truthy and you return `undefined`
-- `routes` object handles static routes, `fetch` function handles dynamic routes and WebSocket upgrades
-- WebSocket handlers receive `ServerWebSocket` where T is the data type attached during upgrade
-- For tests, use different ports per test to avoid conflicts (8315, 8316, etc.) since tests may run in parallel
-- `afterEach` with `server.stop()` ensures clean teardown between tests
-- WebSocket tests need proper timeout handling with Promise wrappers around event callbacks
-- Placeholder responses are simple - just return `new Response()` with appropriate headers/status
-
-## websocket-streaming
-
-- WebSocket data can hold unsubscribe functions directly - `{ id, unsubscribeLogs: (() => void) | null, unsubscribeOutput: (() => void) | null }`
-- When a client connects: (1) send connected message, (2) send history, (3) subscribe to buffer updates
-- History message includes both logs and output in a single `{ type: "history", logs: [], output: [] }` message
-- New entries are sent as individual `{ type: "log", entry }` or `{ type: "output", entry }` messages
-- On disconnect, must call the unsubscribe functions and set them to null to avoid memory leaks
-- Tests for WebSocket message timing can be flaky - avoid sequential `await receiveMessage()` calls across multiple sockets
-- Better pattern: collect all messages in arrays via `onmessage` handlers, then filter and assert after a small delay
-- Exported `WebSocketMessage` type for type-safe parsing in tests and future frontend code
-- The `BufferLogEntry` and `BufferAgentOutput` types needed to be imported from buffer.ts for the message types
-
-## html-shell
-
-- Bun's HTML imports allow `./app.tsx` to be referenced directly in script tags - Bun handles the transpilation automatically
-- Used `
