Setup Atdd Pipeline

/setup-atdd-pipeline

One-time per-repo configuration. Produces .atdd-pipeline.json at the repo root, which every other skill reads at the top of its workflow.

When to use

• First time the plugin runs in a repo.
• After moving the repo to a different tracker.
• Whenever .atdd-pipeline.json is missing.

Interview

Ask, in order. If the answer is unclear, push back; do NOT guess.

1. Tracker. Where do scenario sub-issues live?
   • github — gh CLI, parent / US / scenario hierarchy.
   • local — markdown files under .atdd/issues/ (no remote tracker, for offline / personal use).
2. Repo for GitHub (only if tracker=github). Default: current gh repo view target.
3. Spec base path. Where to write context.md and .feature files. Default: specs/.
4. Test path conventions. One path per test level, used by red-cycle to place new tests:
   • use-case (default: tests/use-case/)
   • e2e (default: tests/e2e/)
   • ui (default: tests/ui/)
5. Commit style. conventional (default) or freeform.
6. Reviewer execution. parallel (default; uses the Agent tool on Claude Code) or sequential (Codex default, or low-budget mode). 6b. Stage 3 execution mode (stage3_mode). sequential (default; one scenario at a time) or workflow (opt-in, experimental, Claude Code only — produces all scenarios in parallel via the shipped atdd-stage3 dynamic workflow, serializing only the merge). workflow silently falls back to sequential when the Workflow tool is unavailable. Leave it sequential unless you have read workflows/atdd-stage3.workflow.mjs and want the parallel path.
7. Shared-language file. Default: CONTEXT.md at repo root. If absent, propose creating one and offer grill-with-docs from mattpocock skills as the way to populate it.
8. ADR directory. Default: docs/adr/. Reviewers consult these.
9. Trunk branch. Default: main. The final PR targets this; sub-PRs MUST NOT target it.
10. Integration branch pattern. Default: atdd/<us-slug>/integration. Sub-PRs (one per scenario) target this branch; once all are merged, the orchestrator opens a single PR from this branch to trunk_branch and stops.
11. Auto-merge of sub-PRs. Default: enabled. Knobs:
    • idle_window_minutes (default 5) — bot inactivity before considering review complete.
    • max_fix_iterations (default 3) — cap on /apply-pr-feedback cycles per sub-PR.
    • watch_timeout_minutes (default 60) — wall-clock cap per sub-PR.
    • merge_method (default squash).
    • bot_logins — extra login allowlist beyond GitHub's user.type == "Bot" (defaults include coderabbitai, coderabbitai[bot], github-actions[bot], codex, codex-bot).

Output

Write .atdd-pipeline.json at the repo root:

{
  "version": 1,
  "tracker": {
    "kind": "github",
    "repo": "owner/name"
  },
  "paths": {
    "specs": "specs/",
    "tests": {
      "use-case": "tests/use-case/",
      "e2e": "tests/e2e/",
      "ui": "tests/ui/"
    },
    "context": "CONTEXT.md",
    "adr": "docs/adr/"
  },
  "commits": "conventional",
  "reviewers": {
    "mode": "parallel"
  },
  "stage3_mode": "sequential",
  "trunk_branch": "main",
  "integration_branch_pattern": "atdd/{us_slug}/integration",
  "auto_merge": {
    "enabled": true,
    "idle_window_minutes": 5,
    "max_fix_iterations": 3,
    "watch_timeout_minutes": 60,
    "merge_method": "squash",
    "bot_logins": [
      "coderabbitai",
      "coderabbitai[bot]",
      "github-actions[bot]",
      "codex",
      "codex-bot"
    ]
  }
}

Idempotency

If .atdd-pipeline.json already exists, read it, present the current values, ask only for fields the user wants to change. Never silently overwrite.

Sanity checks (post-write)

• gh auth status (when tracker=github). Warn if not authenticated.
• Each paths.tests.* directory exists or its parent exists. If neither, ask before creating.
• paths.context exists. If not, suggest invoking grill-with-docs to bootstrap it.
• trunk_branch exists locally and on the remote (git rev-parse --verify origin/<trunk>). Warn otherwise.
• auto_merge.enabled == true AND gh pr merge --help supports the chosen merge_method flag.

Handoff

After completion, suggest the next step: /atdd-run <us-slug> to drive the full pipeline, or /impact-map to capture a new story.
