 **PR target** — Always target the `develop` branch for PRs to AndyMik90/Auto-Claude, NOT `main`.

+**No console.log for debugging production issues** — `console.log` output is not visible in bundled/packaged versions of the Electron app. Use Sentry for error tracking and diagnostics in production. Reserve `console.log` for development only.

 ## Work Approach

 **Investigate before speculating** — Always read the actual code before proposing root causes. Spawn agents to grep and read relevant source files before forming any hypothesis. Never guess at causes without evidence from the codebase.

AndyMik90	4a75ea9f99	fix: handle unknown SDK message types (rate_limit_event) to prevent session crashes The Claude CLI emits message types like rate_limit_event that the SDK's message_parser doesn't recognize, causing MessageParseError to kill the entire agent session stream. This adds two layers of defense: 1. Monkey-patch SDK's parse_message to convert unknown types into safe SystemMessage objects instead of raising 2. safe_receive_messages() wrapper around receive_response() that filters patched messages and catches stream-level errors gracefully Applied to all agent consumers: session, qa_reviewer, qa_fixer, and agent_runner. Also bumps minimum SDK to >=0.1.39. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-20 11:16:59 +01:00

Andy	819f98d9fa	fix: handle empty/greenfield projects in spec creation (#1426 ) (#1841 ) * fix: handle empty/greenfield projects in spec creation and prevent stuck planning state (#1426) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: address PR review findings - planning_phase_ended bug, type hints, dedup (#1426) - Convert planning_phase_ended to instance attribute self._planning_phase_ended so _run_phases() can mark it True after each end_phase() call, preventing double-end on exception propagation - Add Path type annotation to _is_greenfield_project(spec_dir) - Extract duplicated greenfield detection into _check_and_log_greenfield() helper - Add TaskLogger and types.ModuleType type hints to _run_phases() signature - Simplify redundant SystemExit handler with explanatory comment Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: prevent greenfield false positive on missing/corrupt project index When get_project_index_stats() returns {} (file missing, JSON parse error, or unrecognized format), _is_greenfield_project() now returns False instead of incorrectly classifying the project as greenfield. Also removes unused TYPE_CHECKING import and empty conditional block. --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-18 14:49:05 +01:00
Andy	28a620079f	fix: clear terminalEventSeen on task restart to prevent stuck-after-planning (#1828 ) (#1840 ) * fix: clear terminalEventSeen on task restart to prevent stuck-after-planning (#1828) The terminalEventSeen Set in TaskStateManager was never cleared when a task was restarted. When spec_runner.py emits PLANNING_COMPLETE, the taskId is added to terminalEventSeen. If the subsequent coding process (run.py) fails, handleProcessExited() returns early because terminalEventSeen.has(taskId) is true, silently swallowing the PROCESS_EXITED event. The XState actor never transitions, leaving the task permanently stuck in 'coding' state. Additionally, lastSequenceByTask from the old process would cause events from a new process (starting at sequence 0) to be dropped as duplicates. Fix: Add prepareForRestart(taskId) method that clears both terminalEventSeen and lastSequenceByTask without stopping the XState actor. Call it in all 4 locations where a new agent process is started: - TASK_START handler - TASK_STOP handler (so subsequent restart works) - TASK_UPDATE_STATUS auto-start path - TASK_RECOVER_STUCK auto-restart path Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: add prepareForRestart to TASK_REVIEW rejection path Add missing prepareForRestart(taskId) call before startQAProcess() in the TASK_REVIEW rejection handler. This is the 5th location where a new agent process is started for an existing task, but was missed in the original fix. Without this, if the QA fixer process crashes after a review rejection, terminalEventSeen would cause handleProcessExited() to swallow the exit event, leaving the task permanently stuck.

Andy	fb3a3fbda7	fix: watch worktree path for implementation_plan.json changes (#1805 ) (#1842 ) * fix: watch worktree path for implementation_plan.json changes (#1805) The FileWatcher was always watching the main project's spec directory for implementation_plan.json changes. When tasks run in a worktree, the backend writes the plan file to the worktree directory instead, so the watcher never detected changes and subtask progress was never sent to the UI. Changes: - Add getSpecDirForWatcher() helper that checks worktree path first - Update all 3 file watcher setup locations (TASK_START, TASK_UPDATE_STATUS auto-start, TASK_RECOVER_STUCK auto-restart) to use worktree-aware paths - Add re-watch logic in execution-progress handler: when a worktree appears after task start, automatically switch the watcher to the worktree path - Add worktree fallback in exit handler for reading final plan state - Add getWatchedSpecDir() method to FileWatcher for path comparison Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: address PR review findings - naming consistency, async error handling (#1805) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: address PR review findings for file watcher race condition and error handling - Add pendingWatches guard in FileWatcher.watch() to prevent overlapping async calls from creating duplicate watchers (CodeRabbit critical finding) - Add .catch() to all three fire-and-forget fileWatcher.watch() calls in execution-handlers.ts to prevent unhandled promise rejections - Remove shadowed specsBaseDir re-declaration in autoRestart block, reusing the outer variable from the same TASK_RECOVER_STUCK handler scope * fix: address PR review findings for file-watcher race conditions and variable shadowing - Change pendingWatches from Set<string> to Map<string, string> (taskId->specDir) so re-watch calls with a different specDir are allowed through instead of silently dropped - Add cancelledWatches Set to coordinate unwatch() with in-flight watch() calls, preventing watcher leaks when unwatch() runs during watch()'s await points - Add .catch() handler to fileWatcher.unwatch() call in agent-events-handlers exit handler, consistent with the .catch() pattern used for all watch() calls - Remove shadowed const mainSpecDir re-declaration inside autoRestart block in execution-handlers.ts, using the outer variable from the enclosing try block instead Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: resolve FileWatcher race conditions and unhandled promise rejections - Add supersession check in watch() after awaiting existing watcher close to prevent a later concurrent call from having its watcher overwritten - Return early in unwatch() when a watch() is in-flight to prevent double-closing the same FSWatcher - Cancel in-flight watch() calls in unwatchAll() by marking their taskIds in cancelledWatches before closing existing watchers - Add .catch() to fileWatcher.unwatch() calls in TASK_STOP and TASK_RECOVER_STUCK handlers to surface errors instead of silently dropping them Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: resolve concurrent watch() race conditions in FileWatcher - Make finally block conditional so superseding watch() calls are not wiped out by the superseded call cleaning up pendingWatches - Delete watcher from map before awaiting close() to prevent concurrent calls from double-closing the same FSWatcher reference - Make cancelledWatches cleanup conditional on the call still owning the pendingWatches entry, preventing premature flag removal for concurrent calls - Fix misleading comment about mainSpecDir declaration scope Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: resolve PR review findings for FileWatcher dead code, missing guards, and test coverage - Remove dead code in finally block: after delete(), has() is always false so the inner if was always true; simplify to a single delete + cancelledWatches.delete call (Finding 1) - Add implementation_plan.json existence check in getSpecDirForWatcher before preferring the worktree path, so the watcher is started in the correct directory even when the plan file hasn't been written yet (Finding 2) - Clear pendingWatches in unwatchAll() so in-flight watch() calls can no longer register new watchers after a full teardown (Finding 3) - Also clear cancelledWatches in unwatchAll() since in-flight calls bail via the supersession check and won't clean up the flags themselves - Add comprehensive concurrency tests for FileWatcher covering deduplication, supersession, cancellation, and unwatchAll behaviour (Finding 4) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: use path.join() in file-watcher tests for cross-platform compatibility Replace hardcoded forward-slash strings in getWatchedSpecDir assertions with path.join() so expected values match on Windows (backslash) and Unix (forward slash) alike. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: remove duplicate specDir declaration after rebase The rebase on origin/develop introduced a duplicate `const specDir` declaration that caused TypeScript and Biome CI failures.

Andy	76d1d3b032	fix: resolve Claude CLI not found on Windows - PATH, prompt size, cwd (#1661 ) (#1843 ) * fix: resolve Claude CLI not found on Windows - PATH merge, prompt size cap, and cwd (#1661) Three root causes addressed: 1. PATH overwrite: pythonEnv.PATH was overwriting the augmented PATH (with npm globals) in spawn env. Now merges PATH entries instead, prepending python-specific paths (pywin32_system32) while preserving all augmented entries. 2. System prompt size: On Windows, SDK passes system_prompt as --system-prompt CLI arg. Large CLAUDE.md files exceed CreateProcessW's 32,768 char limit, causing misleading "Claude Code not found" error. Now caps CLAUDE.md content on Windows to stay under the limit. 3. Cross-drive cwd: Agent processes were spawned with autoBuildSource as cwd. On Windows with cross-drive setups, this caused file access issues. Now uses projectPath as cwd since all script paths are absolute. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: address PR review findings - constants, logging, CI fixes (#1661) - Extract magic number 24000 into WINDOWS_MAX_SYSTEM_PROMPT_CHARS constant (set to 20000 for more conservative ~12KB CLI headroom) - Extract truncation suffix into WINDOWS_TRUNCATION_MESSAGE constant - Fix double-print when truncation occurs: only print "included in system prompt" when CLAUDE.md was NOT truncated (was_truncated flag) - Fix CI test failures: update subprocess-spawn tests to expect projectPath as cwd instead of autoBuildSource (matches the #1661 CWD change) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: normalize PATH key casing and fix truncation budget on Windows - Normalize env objects to a single uppercase 'PATH' key before merging to prevent duplicate PATH keys on Windows where process.env has 'Path' and getAugmentedEnv() writes 'PATH'. Without this, Object.keys().find() returns 'Path' first (insertion order), discarding augmented entries, and the final spread produces both 'Path' and 'PATH' keys. Follows the same pattern used in python-env-manager.ts. (#1661) - Subtract WINDOWS_TRUNCATION_MESSAGE length from the truncation budget so the final system prompt stays within WINDOWS_MAX_SYSTEM_PROMPT_CHARS. Addresses PR #1843 review findings NEW-001, NEW-002, NEW-003. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: address PR review findings for Windows PATH key casing and truncation budget - Finding 1 (MEDIUM): Prefer 'PATH' key directly when present in env to avoid insertion-order bug where Object.keys().find() returned 'Path' first on Windows - Finding 2 (MEDIUM): Normalization block (delete stale cased key, write 'PATH') already in place from previous commit; Finding 1 fix ensures envPathKey resolves correctly so normalization fires only when truly needed - Finding 3 (LOW): Subtract header template overhead from max_claude_md_chars to prevent ~44-char overshoot in Windows command-line truncation budget (#1661) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: remove stale 'Path' key after PATH normalization on Windows When getAugmentedEnv() spreads process.env on Windows, the resulting object contains both 'Path' (from process.env spread) and 'PATH' (explicitly written by getAugmentedEnv). The prior normalization block only removed non-'PATH' keys when 'PATH' was absent, leaving the stale 'Path' key when both coexisted. Add a cleanup loop to delete all case-variant PATH keys that differ from 'PATH' after the main normalization, ensuring the child process inherits a single canonical 'PATH' entry with the fully-augmented value. (#1661) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: extract shared PATH normalization utilities and add unit tests - Extract normalizeEnvPathKey() and mergePythonEnvPath() into env-utils.ts as shared, exported helpers to eliminate duplicated PATH key case-normalization logic across agent-process.ts and python-env-manager.ts (Finding 3) - Add PATH normalization call in agent-queue.ts spawnIdeationProcess and spawnRoadmapProcess to fix the same Windows PATH duplicate-key issue that was fixed in agent-process.ts (#1661) (Finding 1) - Add comprehensive unit tests for normalizeEnvPathKey() and mergePythonEnvPath() covering Windows-style 'Path' key renaming, duplicate key removal, PATH deduplication across merge, and Unix separator support (Finding 2) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-18 14:22:23 +01:00
Andy	3cb05781fa	fix: handle planning phase crash and resume recovery (#1562 ) (#1844 ) * fix: handle planning phase crash and resume recovery (#1562) When spec creation crashes, the task gets stuck in "planning" state forever because the backend never emits PLANNING_FAILED to the frontend XState machine. Clicking Resume then also crashes because the resume logic transitions to "coding" state, but there are no subtasks yet. Root causes and fixes: 1. Backend orchestrator (orchestrator.py): - Wrap run() in try/except to emit PLANNING_FAILED on unhandled exceptions - Add _emit_planning_failed() calls at every early return path - Fix spec_dir tracking after rename_spec_dir_from_requirements() 2. XState machine (task-machine.ts): - Add PLANNING_STARTED transitions from error and human_review states - This allows tasks that crashed during planning to resume back to planning 3. Execution handlers (execution-handlers.ts): - Detect error state with 0 subtasks and send PLANNING_STARTED (not USER_RESUMED) - Check actual implementation_plan.json for subtasks instead of task.subtasks.length - Handles both with-actor and without-actor (app restart) code paths Closes #1562 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: address PR review findings - reliable subtask check, spec_dir rename, empty except (#1562) - Move planHasSubtasks calculation (reads implementation_plan.json) before XState handling so the crash-during-planning check uses the reliable file-based check instead of task.subtasks.length - Change rename_spec_dir_from_requirements to return the new Path directly instead of a bool, eliminating brittle directory scanning in orchestrator - Add descriptive comment to empty except clause to satisfy code scanning Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: update tests for rename_spec_dir_from_requirements return type change (#1562) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: address PR review findings for planning crash resume - Update phase_executor.spec_dir and spec_validator after directory rename so subsequent phases don't use stale paths (critical bug flagged by sentry, coderabbitai, and Auto Claude review) - Fix TASK_UPDATE_STATUS handler to use file-based plan check instead of unreliable task.subtasks.length (same #1562 bug fixed in TASK_START) - Replace manual subtask counting with existing checkSubtasksCompletion helper - Use safeReadFileSync instead of existsSync+readFileSync (TOCTOU fix) - Add self.validator update to backward-compat _rename_spec_dir_from_requirements Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-18 14:14:09 +01:00
