## Summary

- Put the existing git and test workflows on rails: a repeatable, automated process that can run autonomously, with guardrails and a compact TUI for visibility.

- Flow: for a selected task, create a branch named with the tag + task id → generate tests for the first subtask (red) using the Surgical Test Generator → implement code (green) → verify tests → commit → repeat per subtask → final verify → push → open PR against the default branch.

- Build on existing rules: .cursor/rules/git_workflow.mdc, .cursor/rules/test_workflow.mdc, .claude/agents/surgical-test-generator.md, and existing CLI/core services.

## Goals

- Deterministic, resumable automation to execute the TDD loop per subtask with minimal human intervention.

- Strong guardrails: never commit to the default branch; only commit when tests pass; enforce status transitions; persist logs/state for debuggability.

- Visibility: a compact terminal UI (like lazygit) to pick tag, view tasks, and start work; right-side pane opens an executor terminal (via tmux) for agent coding.

- Extensible: framework-agnostic test generation via the Surgical Test Generator; detect and use the repo’s test command for execution with coverage thresholds.

## Non‑Goals (initial)

- Full multi-language runner parity beyond detection and executing the project’s test command.

- Complex GUI; start with CLI/TUI + tmux pane. IDE/extension can hook into the same state later.

- Rich executor selection UX (codex/gemini/claude) — we’ll prompt per run; defaults can come later.

## Success Criteria

- One command can autonomously complete a task’s subtasks via TDD and open a PR when done.

- All commits made on a branch that includes the tag and task id (see Branch Naming); no commits to the default branch directly.

- Every subtask iteration: failing tests added first (red), then code added to pass them (green), commit only after green.

- End-to-end logs + artifacts stored in .taskmaster/reports/runs/<timestamp-or-id>/.

## User Stories

- As a developer, I can run tm autopilot <taskId> and watch a structured, safe workflow execute.

- As a reviewer, I can inspect commits per subtask, and a PR summarizing the work when the task completes.

- As an operator, I can see current step, active subtask, tests status, and logs in a compact CLI view and read a final run report.

## High‑Level Workflow

1) Pre‑flight

   - Verify clean working tree or confirm staging/commit policy (configurable).

   - Detect repo type and the project’s test command (e.g., npm test, pnpm test, pytest, go test).

   - Validate tools: git, gh (optional for PR), node/npm, and (if used) claude CLI.

   - Load TaskMaster state and selected task; if no subtasks exist, automatically run “expand” before working.

2) Branch & Tag Setup

   - Checkout default branch and update (optional), then create a branch using Branch Naming (below).

   - Map branch ↔ tag via existing tag management; explicitly set active tag to the branch’s tag.

3) Subtask Loop (for each pending/in-progress subtask in dependency order)

   - Select next eligible subtask using tm-core TaskService getNextTask() and subtask eligibility logic.

   - Red: generate or update failing tests for the subtask

     - Use the Surgical Test Generator system prompt .claude/agents/surgical-test-generator.md) to produce high-signal tests following project conventions.

     - Run tests to confirm red; record results. If not red (already passing), skip to next subtask or escalate.

   - Green: implement code to pass tests

     - Use executor to implement changes (initial: claude CLI prompt with focused context).

     - Re-run tests until green or timeout/backoff policy triggers.

   - Commit: when green

     - Commit tests + code with conventional commit message. Optionally update subtask status to done.

     - Persist run step metadata/logs.

4) Finalization

   - Run full test suite and coverage (if configured); optionally lint/format.

   - Commit any final adjustments.

   - Push branch (ask user to confirm); create PR (via gh pr create) targeting the default branch. Title format: Task #<id> [<tag>]: <title>.

5) Post‑Run

   - Update task status if desired (e.g., review).

   - Persist run report (JSON + markdown summary) to .taskmaster/reports/runs/<run-id>/.

## Guardrails

- Never commit to the default branch.

- Commit only if all tests (targeted and suite) pass; allow override flags.

- Enforce 80% coverage thresholds (lines/branches/functions/statements) by default; configurable.

- Timebox/model ops and retries; if not green within N attempts, pause with actionable state for resume.

- Always log actions, commands, and outcomes; include dry-run mode.

- Ask before branch creation, pushing, and opening a PR unless --no-confirm is set.

## Integration Points (Current Repo)

- CLI: apps/cli provides command structure and UI components.

  - New command: tm autopilot (alias: task-master autopilot).

  - Reuse UI components under apps/cli/src/ui/components/ for headers/task details/next-task.

- Core services: packages/tm-core

  - TaskService for selection, status, tags.

  - TaskExecutionService for prompt formatting and executor prep.

  - Executors: claude executor and ExecutorFactory to run external tools.

  - Proposed new: WorkflowOrchestrator to drive the autonomous loop and emit progress events.

- Tag/Git utilities: scripts/modules/utils/git-utils.js and scripts/modules/task-manager/tag-management.js for branch→tag mapping and explicit tag switching.

- Rules: .cursor/rules/git_workflow.mdc and .cursor/rules/test_workflow.mdc to steer behavior and ensure consistency.

- Test generation prompt: .claude/agents/surgical-test-generator.md.

## Proposed Components

- Orchestrator (tm-core): WorkflowOrchestrator (new)

  - State machine driving phases: Preflight → Branch/Tag → SubtaskIter (Red/Green/Commit) → Finalize → PR.

  - Exposes an evented API (progress events) that the CLI can render.

  - Stores run state artifacts.

- Test Runner Adapter

  - Detects and runs tests via the project’s test command (e.g., npm test), with targeted runs where feasible.

  - API: runTargeted(files/pattern), runAll(), report summary (failures, duration, coverage), enforce 80% threshold by default.

- Git/PR Adapter

  - Encapsulates git ops: branch create/checkout, add/commit, push.

  - Optional gh integration to open PR; fallback to instructions if gh unavailable.

  - Confirmation gates for branch creation and pushes.

- Prompt/Exec Adapter

  - Uses existing executor service to call the selected coding assistant (initially claude) with tight prompts: task/subtask context, surgical tests first, then minimal code to green.

- Run State + Reporting

  - JSONL log of steps, timestamps, commands, test results.

  - Markdown summary for PR description and post-run artifact.

## CLI UX (MVP)

- Command: tm autopilot [taskId]

  - Flags: --dry-run, --no-push, --no-pr, --no-confirm, --force, --max-attempts <n>, --runner <auto|custom>, --commit-scope <scope>

  - Output: compact header (project, tag, branch), current phase, subtask line, last test summary, next actions.

- Resume: If interrupted, tm autopilot --resume picks up from last checkpoint in run state.

### TUI with tmux (Linear Execution)

- Left pane: Tag selector, task list (status/priority), start/expand shortcuts; “Start” triggers the next task or a selected task.

- Right pane: Executor terminal (tmux split) that runs the coding agent (claude-code/codex). Autopilot can hand over to the right pane during green.

- MCP integration: use MCP tools for task queries/updates and for shell/test invocations where available.

## Prompts (Initial Direction)

- Red phase prompt skeleton (tests):

  - Use .claude/agents/surgical-test-generator.md as the system prompt to generate high-signal failing tests tailored to the project’s language and conventions. Keep scope minimal and deterministic; no code changes yet.

- Green phase prompt skeleton (code):

  - “Make the tests pass by changing the smallest amount of code, following project patterns. Only modify necessary files. Keep commits focused to this subtask.”

## Configuration

- .taskmaster/config.json additions

  - autopilot: { enabled: true, requireCleanWorkingTree: true, commitTemplate: "{type}({scope}): {msg}", defaultCommitType: "feat" }

  - test: { runner: "auto", coverageThresholds: { lines: 80, branches: 80, functions: 80, statements: 80 } }

  - git: { branchPattern: "{tag}/task-{id}-{slug}", pr: { enabled: true, base: "default" } }

## Risks and Mitigations

- Model hallucination/large diffs: restrict prompt scope; enforce minimal changes; show diff previews (optional) before commit.

- Flaky tests: allow retries, isolate targeted runs for speed, then full suite before commit.

- Environment variability: detect runners/tools; provide fallbacks and actionable errors.

- PR creation fails: still push and print manual commands; persist PR body to reuse.

## Open Questions

1) Slugging rules for branch names; any length limits or normalization beyond {slug} token sanitize?

2) PR body standard sections beyond run report (e.g., checklist, coverage table)?

3) Default executor prompt fine-tuning once codex/gemini integration is available.

4) Where to store persistent TUI state (pane layout, last selection) in .taskmaster/state.json?

## Branch Naming

- Include both the tag and the task id in the branch name to make lineage explicit.

- Default pattern: <tag>/task-<id>[-slug] (e.g., master/task-12, tag-analytics/task-4-user-auth).

- Configurable via .taskmaster/config.json: git.branchPattern supports tokens {tag}, {id}, {slug}.

## PR Base Branch

- Use the repository’s default branch (detected via git) unless overridden.

- Title format: Task #<id> [<tag>]: <title>.

## RPG Mapping (Repository Planning Graph)

Functional nodes (capabilities):

- Autopilot Orchestration → drives TDD loop and lifecycle

- Test Generation (Surgical) → produces failing tests from subtask context

- Test Execution + Coverage → runs suite, enforces thresholds

- Git/Branch/PR Management → safe operations and PR creation

- TUI/Terminal Integration → interactive control and visibility via tmux

- MCP Integration → structured task/status/context operations

Structural nodes (code organization):

- packages/tm-core:

  - services/workflow-orchestrator.ts (new)

  - services/test-runner-adapter.ts (new)

  - services/git-adapter.ts (new)

  - existing: task-service.ts, task-execution-service.ts, executors/*

- apps/cli:

  - src/commands/autopilot.command.ts (new)

  - src/ui/tui/ (new tmux/TUI helpers)

- scripts/modules:

  - reuse utils/git-utils.js, task-manager/tag-management.js

- .claude/agents/:

  - surgical-test-generator.md

Edges (data/control flow):

- Autopilot → Test Generation → Test Execution → Git Commit → loop

- Autopilot → Git Adapter (branch, tag, PR)

- Autopilot → TUI (event stream) → tmux pane control

- Autopilot → MCP tools for task/status updates

- Test Execution → Coverage gate → Autopilot decision

Topological traversal (implementation order):

1) Git/Test adapters (foundations)

2) Orchestrator skeleton + events

3) CLI autopilot command and dry-run

4) Surgical test-gen integration and execution gate

5) PR creation, run reports, resumability

## Phased Roadmap

- Phase 0: Spike

  - Detect test runner (package.json) and git state; render a preflight report.

- Phase 1: Core Rails

  - Implement WorkflowOrchestrator in tm-core with event stream; add Git/Test adapters.

  - Support subtask loop (red/green/commit) with framework-agnostic test generation and detected test command; commit gating on passing tests and coverage.

  - Branch/tag mapping via existing tag-management APIs.

  - Run report persisted under .taskmaster/reports/runs/.

- Phase 2: PR + Resumability

  - Add gh PR creation with well-formed body using the run report.

  - Introduce resumable checkpoints and --resume flag.

  - Add coverage enforcement and optional lint/format step.

- Phase 3: Extensibility + Guardrails

  - Add support for basic pytest/go test adapters.

  - Add safeguards: diff preview mode, manual confirm gates, aggressive minimal-change prompts.

  - Optional: small TUI panel and extension panel leveraging the same run state file.
