Auto Mode
Fully autonomous development. Works through all tasks without stopping until complete.
Current State
!git status --short
!node -e "try{const p=require('./prd.json');const sp=p.sprints?p.sprints[p.sprints.length-1]:p;const s=Object.values(sp.stories||p.stories||{});const name=sp.id||sp.name||p.sprint||'unknown';const done=s.filter(x=>x.passes===true).length;const pend=s.filter(x=>x.passes===null||x.passes===false).length;console.log('Sprint:',name,'| Done:',done,'| Pending:',pend,'| Total:',s.length)}catch(e){console.log('No prd.json')}"
Entry Flow
auto
|-- Activate: write .claude/auto-active
|-- Check prd.json exists?
| |-- No -> Bootstrap from context
| +-- Yes -> Check pending tasks
| |-- None pending -> IDLE Detection
| +-- Has pending -> Execute tasks
|
+-- Execute until done or interrupted
+-- Deactivate: delete .claude/auto-active
Auto-Active Flag (Continuous Execution)
On start, create the flag file:
echo '{"started":"'$(date -Iseconds)'","sprint":"current"}' > .claude/auto-active
PowerShell: @{started=(Get-Date -Format o)} | ConvertTo-Json > .claude/auto-active
This flag tells the Stop hook to block Claude from stopping. Claude keeps working as long as this flag exists.
On exit (user says "done", or nothing left), delete the flag:
rm -f .claude/auto-active
Delete the flag when auto mode ends. If asking the user what's next (IDLE Detection), keep the flag active.
Autonomous Behavior
Do not ask "Should I continue?" or show summaries and wait.
Instead:
- Make autonomous decisions
- Log decisions to
.claude/decisions.md - Keep working until truly done
- The Stop hook prevents Claude from ending — trust it
Persist to prd.json
When findings, scan results, or ad-hoc issues are identified during execution, write them to prd.json as stories before fixing them. prd.json is the source of truth that survives session restarts and /compact.
Lightweight Mode
If the user gives a direct instruction (e.g., "fix this button", "update that copy") rather than saying "auto":
- Skip prd.json and sprint creation entirely
- Just fix, verify, done
- Use prd.json only when there are 5+ tasks to track
Bootstrap (No prd.json)
When prd.json does not exist:
- Read CLAUDE.md, README.md, package.json for context
- Generate 5-10 starter tasks based on project
- Create prd.json with stories
- Continue immediately — do not stop for approval
Pre-flight (Quick)
Before first task:
git status --short
npm run build 2>&1 | tail -5
Skip if takes >10 seconds.
Task Execution
Find Next Task
// prd.json has two shapes:
// Flat: { stories: { "S1-001": {...} }, sprint: "sprint-1" }
// Nested: { sprints: [{ id: "sprint-1", stories: { "S1-001": {...} } }] }
const sp = prd.sprints ? prd.sprints[prd.sprints.length - 1] : prd;
const stories = sp.stories || prd.stories || {};
const storyEntries = Object.entries(stories);
const executable = storyEntries.filter(([id, s]) =>
s.passes !== true &&
(s.blockedBy || []).every(dep => stories[dep]?.passes === true)
);
Execute Each Task
- Read the task description
- Context Loading — read 2-3 similar files to match existing patterns
- Implement the solution
npm run typecheck— fix if failsnpm run build— fix if fails- Self-Verification (see below)
- Update prd.json:
passes: true - Start next task immediately
Context Loading (before writing any code)
- Read 2-3 existing files most similar to what you're building
- Identify patterns: naming conventions, import style, error handling, state management
- Match patterns — do not introduce new patterns when existing ones cover the use case
Verification
| Task Type | Verification |
|---|---|
| UX/UI | agent-browser visual + console + network |
| Feature | Build passes + browser devtools check |
| API | Endpoint returns expected data + network check |
| Bug fix | Reproduce, verify fixed, no new errors |
For UI/API tasks with a running dev server:
agent-browser open http://localhost:3000/path
agent-browser snapshot -i
agent-browser errors
agent-browser network requests
Fix console errors or failed network requests before moving on.
Self-Verification (after each task)
Before marking any task as complete:
1. Type Safety
npm run typecheck 2>/dev/null || npx tsc --noEmit 2>/dev/null
2. Tests
npm test -- --passWithNoTests --watchAll=false 2>/dev/null
3. Self-Review
Run git diff and check:
- No
console.logordebuggerleft in - No hardcoded colors (use design tokens)
- All UI states handled (loading, empty, error)
- No
anytypes introduced - No commented-out code
4. UI/API Change? Browser Verification If agent-browser is available and a dev server is running:
agent-browser open http://localhost:3000/[page]
agent-browser screenshot .claude/screenshots/verify-$(date +%s).png
agent-browser snapshot -i
agent-browser errors
agent-browser network requests --filter api
5. Mark Complete Only after all checks pass. If any check fails, fix it first.
Parallel Execution (Optional)
For independent tasks, launch multiple agents:
Task({ subagent_type: "general-purpose", prompt: "...", run_in_background: true })
Smart Retry
On failure (maximum 2 retries, then move on):
- Log to
.claude/mistakes.md - Retry 1: Different approach
- Retry 2: Simplest possible implementation
- Still fails: set
passes: false, continue to next task
Do not retry a third time. Do not spend more than 10 minutes on retries for a single task.
Commit Cadence
- Commit every 3 completed tasks
- Or after major milestones
- Use conventional commits:
feat|fix|refactor
Token Management
After every 3 completed tasks, recommend /compact:
Checkpoint: 3 tasks complete. Run /compact to reclaim ~40% tokens.
Be concise. Short responses = more runway.
Completion
When all stories have passes === true:
All [N] tasks complete.
Summary:
- [X] features implemented
- [X] bugs fixed
- [X] improvements made
Run `progress` to see full results.
IDLE Detection (Smart Next Action)
If no tasks to work on:
- Are all stories
passes: true?- No: find blocked tasks and resolve blockers
- Yes: continue to step 2
- Output completion summary for current sprint
- Assess context to decide next action:
Decision Matrix
| Signal | Action |
|---|---|
| TODOs/FIXMEs in code | Brainstorm (auto mode creates stories) |
| Console.logs left in | Quick cleanup sprint |
| No tests exist | Suggest test sprint |
| Build warnings | Fix warnings sprint |
| Clean codebase | Ask user (see below) |
Auto-Continue (Obvious Work)
If brainstorm scan finds 3+ actionable improvements, auto-create next sprint and continue:
Sprint [N] complete (8/8 tasks).
Scanning codebase... found 5 improvements.
Creating Sprint [N+1] and continuing.
Limit: 1 auto-generated sprint per session. After that, ask the user.
Ask User (No Obvious Work or Limit Reached)
Sprint [N] complete (8/8 tasks).
What's next? (Recommended: ship)
1. ship - Deploy current work
2. audit - Deep quality check
3. brainstorm - Find more improvements
4. Done for now
Use AskUserQuestion with these options. Pick recommendation based on context.
Keep .claude/auto-active flag while asking. Only delete it if user picks "Done for now".
Quick Reference
| Situation | Action |
|---|---|
| No prd.json | Bootstrap from context |
| All done + issues found | Brainstorm (auto-creates stories) |
| All done + clean code | Ask user for next action |
| All done + already auto-sprinted | Ask user (limit reached) |
| Build broken | Fix first |
| Task fails | Retry 2x, then skip |
| UX task | Browser verify |
| Blocked task | Skip, work on unblocked |
| < 5 tasks, no sprint | Work directly |
