there's a separate `add-dex-tests` task for that -- Dex stores tasks in `.dex/tasks.jsonl` at git root or pwd, found via `dex dir` - -## update-loop-for-dex - -- Replaced `readTasks`, `countTasks`, `updateTaskStatus`, `writeTasks` imports with dex functions: `isDexAvailable`, `dexStatus`, `dexListReady`, `dexShow` -- DexStatus.stats uses different field names than TaskCounts: `completed` vs `complete`, `inProgress` vs `in_progress` -- Added `isDexAvailable()` check early in loop to fail fast with helpful install instructions -- The agent prompt now includes next task context from `dexShow()` when available (id, name, description, blockedBy) -- Removed TASKS.md file existence check since dex manages tasks, kept PROMPT.md check -- Existing loop.test.ts tests will fail because they rely on TASKS.md file format - these tests will be updated in `update-loop-tests` task -- Non-loop tests (84 tests) continue to pass, loop tests (11 tests) are expected to fail until mocked -- The loop still references TASKS.md in the prompt and files array - this will be updated when PROMPT.md template is updated - -## update-status-command - -- Replaced imports from `src/tasks.ts` with imports from `src/dex.ts`: `dexStatus()` for counts, `dexListReady()` for next task -- `DexStatus.stats` uses `completed` (not `complete`), `inProgress` (not `in_progress`), and includes `pending`, `blocked`, `ready` counts -- Added guard for division by zero when `stats.total === 0` in progress bar width calculation -- `dexStatus()` includes `inProgressTasks` array directly, no need to filter separately -- `dexListReady()` returns tasks sorted by priority, so first element is the next task to work on -- The status command uses `task.name` (from DexTask) instead of `task.content` (from old Task interface) - -## add-tasks-to-dex-migration - -- Reused `parseTasks` from `src/tasks.ts` directly in `parseTasksForMigration` - no need to duplicate parsing logic -- `importTaskToDex` runs dex commands sequentially: add task, set dependencies, update status -- Dex block command uses `--by` flag: `dex block --by ` -- For completed tasks, used `--result "Migrated from TASKS.md"` to provide context -- Added `importAllTasksToDex` helper function that returns a `MigrationReport` with success/failure counts -- Type imports require `type` keyword due to `verbatimModuleSyntax` in tsconfig - -## add-dex-migration-prompt - -- Used `node:readline/promises` `createInterface` for interactive prompts - cleaner async/await pattern than callback-based readline -- `checkNeedsDexMigration()` checks both TASKS.md existence AND `.dex/tasks.jsonl` emptiness/absence to determine if migration needed -- Used `getDexDir()` from dex module which returns null when dex directory doesn't exist (dex dir command fails) -- Exported `MigrationChoice` as enum with values `Port`, `Archive`, `Exit` for type-safe choice handling -- Keep colors object local to module for console output styling - pattern used across other commands -- The 11 loop.test.ts failures are expected and documented in learnings - they depend on TASKS.md workflow and will be fixed in update-loop-tests task - -## add-dex-migration-execution - -- `executeDexMigration()` dispatches to three helper functions based on MigrationChoice: `executePortMigration`, `executeArchiveMigration`, `executeExitWithDowngrade` -- Port migration: init dex → parse TASKS.md → import each task via `importTaskToDex()` → remove TASKS.md on success -- Archive migration: create timestamped backup with `-pre-dex` suffix → move entire `.math/todo/` → init dex → recreate `.math/todo/` with fresh PROMPT.md and LEARNINGS.md from templates -- Archive has rollback: if `dex init -y` fails after moving todo dir, it restores the backup directory -- Used `rmSync` for deleting TASKS.md and `renameSync` for moving directories (synchronous is fine for single operations) -- `migrateTasksToDexIfNeeded()` is the main orchestration function - returns `MigrationChoice | undefined` to indicate what action was taken -- Exit handler uses `process.exit(0)` after printing downgrade instructions - clean exit, not an error -- Timestamp format uses ISO format with colons/periods replaced by dashes for filesystem compatibility (e.g., `2026-01-29T14-14-58-pre-dex`) - -## integrate-dex-migration-check - -- Migration check is placed in `main()` after parsing args but before the switch statement, ensuring it runs early -- Help commands (`help`, `--help`, `-h`, `undefined`) are excluded from migration check to allow users to see help even before migration -- `migrateTasksToDexIfNeeded()` handles all the orchestration internally - just need to call it and let it run -- If user selects "Exit", the function calls `process.exit(0)` internally, so no return value handling needed for that case -- For "port" or "archive" choices, the function returns and execution continues to the requested command -- 11 loop.test.ts failures are pre-existing (documented in previous learnings) and will be fixed in `update-loop-tests` task - -## add-dex-migration-tests - -- Replaced integration tests for `importTaskToDex` with mocked unit tests to avoid dependency on dex CLI availability -- Used in-test mock modules that track executed commands rather than actually running dex commands -- Mock approach: create a mock function that records what dex commands would be called (dex add, dex block, dex complete, dex start) -- Tests verify correct command sequence: add task first, then set dependencies via block, then update status -- Added tests for error cases: failure on add, failure on block (dependency not found) -- Existing tests for `checkNeedsDexMigration()`, `parseTasksForMigration()`, and archive backup structure already had good coverage -- Pre-existing 11 loop.test.ts failures are unrelated - they're from dex integration in loop.ts and will be fixed in `update-loop-tests` task - -## update-init-for-dex - -- Removed `TASKS_TEMPLATE` import since dex manages tasks, only create PROMPT.md and LEARNINGS.md -- Used `isDexAvailable()` to check if dex CLI is installed before attempting initialization -- Used `getDexDir()` to check if `.dex/` already exists and reuse it (returns path or null) -- Run `dex init -y` only when dex is available AND no existing .dex directory found -- Added helpful warning message when dex CLI is not found, with install instructions -- Updated "Next steps" to show `dex add "Your first task"` instead of editing TASKS.md -- 2 init.test.ts failures are expected - they check for TASKS.md which we no longer create -- Init test updates are deferred to separate `update-init-tests` task per task dependency graph - -## update-iterate-for-dex - -- Added `dexArchiveCompleted()` function to `src/dex.ts` that wraps `dex archive --completed` and returns archive count -- Iterate command now archives completed dex tasks instead of backing up TASKS.md to `.math/backups/` -- LEARNINGS.md is still backed up to `.math/backups/` with a timestamped filename (e.g., `LEARNINGS-2026-01-29T14-49-27-000Z.md`) -- Removed dependency on `generatePlanSummary` and `TASKS_TEMPLATE` since we no longer use TASKS.md -- Changed backup flow: instead of copying entire `.math/todo/` to a summary-named backup dir, we archive dex tasks and backup only LEARNINGS.md -- Updated "Next steps" message to show `dex add` instead of editing TASKS.md -- Added `isDexAvailable()` check at start of iterate to fail fast with helpful error message -- The archive output parsing uses regex to extract count from "Archived N task(s)" format - returns 0 if no match -- No iterate.test.ts exists, so no test updates needed for this task - -## update-prompt-template - -- Rewrote `PROMPT_TEMPLATE` in `src/templates.ts` to replace TASKS.md-based workflow with dex commands -- Key changes to "The Loop" section: replaced steps about reading/updating TASKS.md with dex equivalents: - - `dex list --ready` to find eligible tasks - - `dex start ` to mark in-progress - - `dex show ` for full task context - - `dex complete --result "..."` to mark complete -- Added new "Dex Commands" reference table with all key dex commands and their purposes -- Updated "Dependencies Matter" sign to reference `dex list --ready` instead of manual status checking -- Kept all four existing signs intact: One Task Only, Learnings Required, Commit Format, Don't Over-Engineer -- Updated Directory Structure to remove TASKS.md reference (now just PROMPT.md, LEARNINGS.md) -- No tests for template content itself - changes are documentation-only -- Pre-existing test failures (13 in loop.test.ts and init.test.ts) are unrelated - they're from dex integration and will be fixed in `update-loop-tests` and `update-init-tests` tasks - -## update-existing-prompt-md - -- Updated `.math/todo/PROMPT.md` with dex instructions matching the new `PROMPT_TEMPLATE` from `src/templates.ts` -- Key customization: kept project-specific Quick Reference commands (`bun test`, `bun run typecheck`, `bun ./index.ts `) rather than using placeholders -- The template in `src/templates.ts` has generic placeholders (``, etc.) for new projects, but the live PROMPT.md should have actual commands -- Documentation-only task - no code changes, no new tests needed -- Pre-existing 13 test failures (loop.test.ts, init.test.ts) are unrelated to this task and documented in previous learnings - -## add-dex-tests - -- Created `src/dex.test.ts` with 22 unit tests covering the dex module -- Tests focus on type interfaces, JSON parsing, and simulated function behavior since actual dex CLI calls are difficult to mock -- Used pattern of "simulate" functions that replicate the error handling logic without actual shell calls -- Tested `DexTask`, `DexTaskDetails`, and `DexStatus` interfaces with sample JSON responses -- Archive output parsing tests verify regex extraction of "Archived N task(s)" format -- Edge case tests cover: all optional fields populated, nested children in subtasks, malformed JSON handling -- All 22 tests pass independently; pre-existing 13 failures in loop.test.ts and init.test.ts are separate tasks (`update-loop-tests`, `update-init-tests`) -- Pattern: when mocking shell commands isn't practical, test the JSON parsing and error handling logic by simulating command outcomes - -## update-init-tests - -- Used `mock.module("../dex", ...)` to mock `isDexAvailable()` and `getDexDir()` functions from dex module -- Created `createMockShell()` helper function that returns a mock `Bun.$` to intercept `dex init` calls -- The mock shell returns a no-op result for all commands rather than calling the real shell - avoids actual shell execution during tests -- Key tests: (1) PROMPT.md/LEARNINGS.md created but not TASKS.md, (2) dex init called when no .dex exists, (3) dex init NOT called when .dex exists, (4) dex init NOT called when dex unavailable -- Module-level variables (`mockDexAvailable`, `mockDexDirPath`, `dexInitCalled`) track mock state and are reset in `beforeEach()` -- Cast the mock shell function using `as unknown as typeof Bun.$` to satisfy TypeScript since we're not fully implementing the shell interface - -## remove-tasks-module - -- Deleted `src/tasks.ts` since dex now handles all task management -- Moved `Task` interface and `parseTasks()` function to `src/migrate-tasks.ts` to preserve migration functionality -- Updated imports in `src/migrate-to-dex.ts` and `src/migrate-to-dex.test.ts` to use `src/migrate-tasks.ts` instead of `src/tasks.ts` -- Added `parseTasksForMigration()` as an alias for `parseTasks()` for backwards compatibility in test files -- The 13 pre-existing test failures in `loop.test.ts` and `init.test.ts` are NOT caused by this task - they were already failing due to dex integration changes -- Those test failures will be fixed by separate pending tasks: `update-loop-tests` and `update-init-tests` -- Migration tests (19 tests) all pass after the changes, confirming the parsing logic works correctly in its new location - -## update-loop-tests - -- Bun's `mock.module()` is the proper way to mock ES module imports - direct property assignment fails with "readonly property" error -- Mock functions must be declared at module level and then re-assigned in `beforeEach()` to reset state between tests -- When a mock function needs arguments, use `mock((_param: Type) => ...)` syntax to satisfy TypeScript -- Created helper functions `createMockDexStatus()`, `createMockDexTask()`, `createMockDexTaskDetails()` to easily construct mock data with overrides -- Tests no longer create TASKS.md files - they mock `dexStatus()`, `dexListReady()`, and `dexShow()` instead -- Added new "runLoop dex integration" test suite with 6 tests covering: dex availability check, dex status errors, no tasks error, in_progress warning, completion success, and task details in prompt -- The `mock.module()` call affects the module immediately for ESM imports, so re-importing with `await import("./loop")` in each test ensures the mocks are used -- Pre-existing init.test.ts failures (2 tests) remain -
