name: undercity description: Dispatch tasks to the undercity orchestrator for autonomous batch execution. Use when adding tasks, checking status, or running parallel work. Ideal for multi-task workloads that benefit from autonomous verification. allowed-tools: Bash(node ./bin/undercity.js:), Bash(pnpm start:)

Undercity Task Orchestrator

Dispatch work to undercity for autonomous, parallel execution with built-in verification (typecheck, test, lint).

When to Use Undercity

Good fit:

• Multi-step tasks that can run independently
• Batch refactoring across many files
• Work that benefits from verification loops
• Tasks to run overnight/in background

Skip undercity for:

• Single quick fixes (do directly)
• Questions/explanations
• Exploratory debugging

Commands

Add a Task

Copynode ./bin/undercity.js add "task description"

Examples:

Copynode ./bin/undercity.js add "Fix all TypeScript strict null check errors in src/"
node ./bin/undercity.js add "Add JSDoc comments to all exported functions"
node ./bin/undercity.js add "Migrate deprecated API calls to v2"

Add Task with Context (Handoff)

Pass context to help workers start with relevant information:

Copy# Pass files you've already analyzed
node ./bin/undercity.js add "Refactor auth module" --files-read "src/auth.ts,src/types.ts"

# Pass notes about decisions or constraints
node ./bin/undercity.js add "Fix validation bug" --notes "Issue is in validateInput(), not the schema"

# Pass full context via JSON file
node ./bin/undercity.js add "Implement feature X" --context ./handoff.json

Context JSON format:

Copy{
  "filesRead": ["src/api.ts", "src/types.ts"],
  "decisions": ["Use zod for validation", "Keep backward compatible"],
  "notes": "Auth token is in request headers"
}

Check Task Board

Copy# All tasks
node ./bin/undercity.js tasks

# Only pending
node ./bin/undercity.js tasks pending

# Only completed
node ./bin/undercity.js tasks complete

Mark Tasks Complete

Copy# Mark task as complete
node ./bin/undercity.js complete <task-id>

# With resolution notes
node ./bin/undercity.js complete <task-id> --resolution "Fixed in commit abc"

# With reason (alias for --resolution, useful for closures)
node ./bin/undercity.js complete <task-id> --reason "Already implemented"
node ./bin/undercity.js complete <task-id> --reason "Deferred"

Start Autonomous Execution

Copy# Process all pending tasks
node ./bin/undercity.js grind

# Limit concurrent workers
node ./bin/undercity.js grind --parallel 2

# Process specific number of tasks
node ./bin/undercity.js grind -n 5

Monitor Progress

Copy# Live TUI dashboard
node ./bin/undercity.js watch

# Current status snapshot
node ./bin/undercity.js status

# Rate limit status
node ./bin/undercity.js limits

Workflow Patterns

Batch Task Setup

Add multiple related tasks, then let grind handle them:

Copynode ./bin/undercity.js add "Migrate UserService to new auth pattern"
node ./bin/undercity.js add "Migrate OrderService to new auth pattern"
node ./bin/undercity.js add "Migrate PaymentService to new auth pattern"
node ./bin/undercity.js grind --parallel 3

Conservative Execution

For careful work, run single-threaded:

Copynode ./bin/undercity.js grind --parallel 1

Check Before Starting

Always verify what's queued:

Copynode ./bin/undercity.js tasks pending

Task Description Guidelines

Write clear, actionable task descriptions:

Good:

• "Fix TypeScript error TS2345 in src/api/client.ts"
• "Add input validation to all POST endpoints in src/routes/"
• "Replace deprecated lodash _.pluck with _.map"

Vague (avoid):

• "Fix bugs" (which bugs?)
• "Improve performance" (where? how?)
• "Clean up code" (too broad)

Output Modes

Undercity auto-detects output format:

• TTY: Human-friendly with colors
• Pipe: Machine-readable JSON

Force a mode:

Copynode ./bin/undercity.js tasks --human
node ./bin/undercity.js tasks --agent

Important Notes

• Tasks execute in isolated git worktrees
• All changes verified (typecheck, test, lint) before commit
• Tasks merge to main serially (no conflicts)
• Failed tasks can be retried with model escalation
• Check node ./bin/undercity.js limits before large batches
