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

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/.
