description	Fetch, implement, and close GitHub/GitLab issues sequentially (one main issue starting with PRD:/feat: at a time). Handles parallel subtasks, dependency parsing, worktrees, and env propagation.

Work on Issues

Fetches GitHub/GitLab issues, triages, implements sequentially (one main issue at a time), runs find-mismatch reviews, and closes.

1. Tracker Setup

Detect host via git remote -v. Set $TRACKER to gh or glab. Terminologies:

• GitHub: pr / comment
• GitLab: mr / note

---

2. Phase 1: Fetch & Triage

1. List open issues: Use gh issue list --state open --json number,title,labels or glab issue list -O json.
2. Filter: Keep only main issues (title starts with PRD: or feat:). Others are skipped for auto/batch runs (but allowed if explicitly picked).
3. Choice: User selects issue number or onwards mode.
4. Pre-checks:
   • Verify open (Skip if closed).
   • Detect PRD/Epic by label PRD or title prefix PRD:. Skip implementation, add to $PRD_TRACKER for auto-close check.
5. Read Details: Fetch full issue view and comments (gh issue view --comments / glab issue view --comments).
6. Assign & Label: Mark in-progress, remove needs-triage.

---

3. Dependencies & Linking

Parse ## Blocked by in issue body (matches #42 or full issue URL) to build DEPS[issue] = [blockers]. If possible, create native tracker links (e.g., GitLab API /links with is_blocked_by or GitHub sub-issues API with blocked_by=true). Fall back to text references.

---

4. Phase 2: Implement (One Main Issue at a Time)

1. Create Worktree:

   git worktree add .claude/worktrees/issue-<number> -b work-on-issue-<number>
   

2. Copy .env files: Copy .env and .env.* files into worktree directory.
3. Dispatch Sub-Agent (subagent_type: "full-stack-engineer" inside .claude/worktrees/issue-<number>): Prompt spec:

   Implement issue #<number>: <title>.
   Acceptance Criteria: <AC>
   Branch/Worktree: work-on-issue-<number> in .claude/worktrees/issue-<number>
   API/best-practices: Search via `context7` or web.
   Compile/Lint errors: If 3+ consecutive failures, check Reference Directories (<RefDirs>) to align configurations.
   Parallel subtasks: Decompose & dispatch sub-agents if tasks are independent (no shared files/dirs).
   Post-implementation: Run `find-mismatch` skill on modified files only. Auto-apply confirmed fixes without prompting. Re-run tests.
   Output: Summary, find-mismatch fixes, tests run, and commit hash.
   Commit format: `fix: resolve #<number> — <short description>`
   

4. Verify: Check output, diff, and run tests.
5. Commit: Ensure changes are committed in worktree (fix: resolve #<number> — <desc>).

---

5. Phase 3: Submit & Close

1. Create PR/MR: Link to issue using "Closes #".
2. Auto-Merge: Merge immediately (squash & delete branch).
3. Comment: Post summary of implementation.
4. Close: Remove triage/progress labels, add ai-agent-closed, and close issue.
5. Propagate .env files: Copy modified env files back to main working directory before worktree removal:

   WT=.claude/worktrees/issue-<number>
   for wtf in "$WT"/.env "$WT"/.env.*; do
     [ -f "$wtf" ] || continue
     base=$(basename "$wtf")
     if [ ! -f "$base" ] || ! cmp -s "$base" "$wtf"; then
       cp "$wtf" "$base" && echo "Propagated $base back"
     fi
   done
   

6. Clean up:

   git worktree remove .claude/worktrees/issue-<number>
   git branch -d work-on-issue-<number>
   

---

6. PRD Auto-Close

After closing a sub-issue, check all PRDs in PRD_TRACKER. Read PRD description/links. If all referenced sub-issues (#42 etc.) are closed, close the PRD and remove from PRD_TRACKER.

---

7. Subtask Parallelization

Decompose main issue into subtasks if:

• Touch non-overlapping files/folders.
• Independent outputs (no order dependency). Keep sequential if they share files, have strict flow dependencies, or need configuration first.

Subtask Prompt Spec:

Implement subtask for issue #<number>: <title>.
Subtask: <details>
Working Directory: .claude/worktrees/issue-<number>
Scope: Modify <MAY_MODIFY>, DO NOT modify <MUST_NOT_MODIFY>.
Compile/Lint errors: If 3+ consecutive failures, check Reference Directories (<RefDirs>).
Post-implementation: Run `find-mismatch` on modified files, auto-fix.
Verification: Run relevant tests. Return summary, modified files, test results.

---

8. Execution Modes

Batch & Onwards Mode

1. Fetch all open issues, filter to main issues (PRD:, feat:).
2. Parse DEPS map from issue bodies, set formal links.
3. Show progress table: | Issue | Title | Type | Blocked By | Agent | Status | PR/MR |
4. Loop:
   • Select next issue with zero unresolved blockers. Skip closed or PRD issues.
   • Dispatch sub-agent to worktree.
   • Run verification -> PR/MR merge -> close -> env propagation -> clean up -> check PRDs.
   • Re-evaluate dependencies. Repeat.
5. Re-fetch all open issues after finishing (Outer loop) to pick up new main issues. Exit only if no open main issues remain or user interrupts.

Single Issue Mode

Execute the selected issue solo. Skip dependency graph processing.

9. Labels & Helpers

Label	Meaning	Color
PRD	Parent tracking issue	#0075CA
in-progress	Active	#E4E669
ready-for-agent	Ready for agent	#0E8A16
ai-agent-closed	Closed by AI	#5319E7

To apply labels, try updating directly. If not found, create label first (e.g. color #E4E669 for in-progress) and retry.

10. Edge Cases

• No CLI: Use APIs directly or ask user to install gh/glab.
• Conflict/Cycle: Report circular dependencies, skip affected issues.
• External Blockers: Treat open external issues as unresolved blockers.
• API Link Failure: Fall back to text references.
• No Main Issues: Inform user, ask if they want to process non-main issues.
• Env files gitignored: Env files must be propagated back before worktree removal to persist across runs. Do not commit secrets.
