Agent skill

bdd-orchestrating

BDD orchestrator for feature-level work. Use when user says 'add', 'implement', 'build', 'feature', 'iteration', 'story', 'phase', 'resume', 'continue', or references a ticket/iteration/story. Also use when work touches 3+ files with new state/flows, or when user runs /bdd. Do NOT use for bug fixes, typos, config changes, or 1-2 file tasks.

BDD Orchestrator

Behavior-first development for features. Discovery → Scenarios → Implementation.

Iron Law: DEFINE BEHAVIOR BEFORE IMPLEMENTATION

Phase Tracking

Features progress through phases. Track in ticket frontmatter:

yaml
---
type: feature
phase: implement # intake | define-behavior | scenario-gate | decomposition | implement | done
---

Phase meanings:

Phase What happens Details
intake Context check, discovery (Phase 0-2) DISCOVERY.md
define-behavior Writing Given/When/Then (Phase 3) SCENARIOS.md
scenario-gate Validating scenarios (Phase 4) SCENARIOS.md
decomposition Task breakdown (Phase 5) DECOMPOSITION.md
implement Outside-in TDD (Phase 6) TDD.md
done Cleanup, verification (Phase 7) DONE.md

Update phase when:

  • Completing a BDD phase → set next phase
  • Handing off to TDD → set implement
  • All scenarios pass → set done

Resume Logic

When user references a ticket, resume work:

  1. Read ticket → get current phase:
  2. Find progress → first unchecked [ ] in test-definitions
  3. Check context → read last work log entry
  4. Announce resume → "Resuming at [phase]. Last: [log entry]."

Resume by phase:

Phase Resume action
intake Start context check (Phase 0-2)
define-behavior Continue drafting scenarios
scenario-gate Continue validating scenarios
decomposition Continue task breakdown
implement Find first unchecked scenario, run TDD
done Run /done and /audit checks

Current Behavior

  1. Detect work level (see SAFEWORD.md "Work Level Detection")
  2. If user references iteration/story/phase from a spec:
    • Check if child ticket exists for that iteration
    • If not → create ticket, run full BDD
    • If yes → resume at current phase
  3. Announce with override hint
  4. If ticket exists: Read phase, resume at appropriate point
  5. Artifact-first rule: Before doing work, create/verify the phase artifact:
    • Phase 0-2 → ticket at .safeword-project/tickets/{id}-{slug}/ticket.md
    • Phase 3 → test-definitions at .safeword-project/tickets/{id}-{slug}/test-definitions.md
    • Phase 5 → task breakdown in ticket
  6. Execute phase using the appropriate phase file
  7. Update phase in ticket when transitioning

Phase Files

Load the appropriate file based on current phase:

Phase File
intake DISCOVERY.md
define-behavior SCENARIOS.md
scenario-gate SCENARIOS.md
decomposition DECOMPOSITION.md
implement TDD.md
done DONE.md

For splitting large features, see SPLITTING.md.

Key Takeaways

  • patch/task → TDD directly (RED → GREEN → REFACTOR)
  • feature → full BDD flow (Phases 0-7), track in ticket phase: field
  • Resume → read ticket, find first unchecked scenario, continue
  • Split → check thresholds at Entry, Phase 3, Phase 5; user decides (see SPLITTING.md)
  • Done gate → run /done before marking ticket complete
  • When unsure → default to task, user can /bdd to override
