# Plan Pipeline Orchestrator Orchestrates the complete plan-to-execution pipeline. Can run the full pipeline or a single isolated stage. ## Stages | Stage | Skill | Purpose | |-------|-------|---------| | 1 | `/plan-pipeline:ceo-review` | Challenge the brief, lock product direction | | 2 | `/plan-pipeline:eng-review` | Lock architecture, diagrams, and test matrix | | 3 | `/plan-pipeline:start` | 5-phase planning: PRD, research, ADRs, task list | | 4 | `/plan-pipeline:validate` | 2-layer validation before any code is written | | 5 | `/plan-pipeline:execute` | Worktree isolation, parallel agents, quality gate, PR | ## Usage ``` /plan-pipeline # full pipeline, asks for context /plan-pipeline --from=start # skip gates, start from planning phase /plan-pipeline --from=validate # validate an existing plan /plan-pipeline --from=execute # execute a validated plan ``` ## When to Use Each Stage **ceo-review**: use before any significant feature when the direction is not locked. Especially valuable when the request is specific (specificity signals collapsed solution space). **eng-review**: use after direction is locked. Required for features with async components, external dependencies, or multi-step flows. **start**: use for any non-trivial feature touching more than 2 files or involving architecture decisions. **validate**: always before execute. The cost of validation is negligible against the cost of discovering issues mid-execution. **execute**: after validate confirms all issues are resolved. ## Workflow 1. **Collect context**: what are we building, and what stage do we start from? 2. **ceo-review**: product direction gate (can be skipped with `--from=eng-review` or later) 3. **eng-review**: architecture gate (can be skipped with `--from=start` or later) 4. **CHECKPOINT**: ask user to confirm direction and architecture before planning 5. **start**: run 5-phase planning, produce `docs/plans/plan-{name}.md` 6. **CHECKPOINT**: present plan for review before validation 7. **validate**: 2-layer validation (structural + specialist agents) 8. **execute**: worktree isolation -> parallel agents -> quality gate -> PR ## Dependency Graph ``` ceo-review | eng-review | start | validate | execute ``` ## Notes Each stage writes its output to disk before the next stage begins. If the pipeline is interrupted, resume with `--from=<stage>` using the correct stage name. All decisions are recorded in `docs/plans/plan-{name}.md` and the corresponding ADRs in `docs/adr/`.
