| description | Orchestrate bootstrapping a working MVP from a design or spec document — ingest the doc, plan thin vertical slices, scaffold the first end-to-end slice, then TDD-implement, review, and gated commit. Use to turn an SDD/PRD into a running starting point. Use when a design or spec document must become a running MVP through planned vertical slices. |

orch-build-mvp
Actor · action · target: orch · build · mvp. Thin wrapper over the shared
engine in orch-pipeline.
When to Use
- The user has a design / spec document (SDD, PRD, system_design) and wants a
working vertical slice bootstrapped from it.
- Takes a doc path as its argument, e.g.
civicpulse/docs/SDD-v0.6.md.
Operation settings
- Default size floor: large — this is the full pipeline including Scaffold.
- Phase mask: 0 (read the spec) → 1 → 2 (heavy) → 3 (scaffold) → 4 → 5 → 6.
- First move (phase 0 → 2): read the doc; extract scope, locked decisions,
and the feature list; order it into thin vertical slices (one end-to-end
path first, not all-models-then-all-views). Phase 3 stands up that first slice.
How It Works
- Run the
orch-pipeline engine with the settings above.
- Reuse the existing GAN harness instead of hand-rolling an iterate loop:
- Translate the SDD into
gan-harness/spec.md + gan-harness/eval-rubric.md
(this stands in for what gan-planner would generate — you already have the spec).
- Drive the build with
/gan-build "<one-line brief>" --skip-planner
(defaults: --max-iterations 15, --pass-threshold 7.0,
--eval-mode playwright; use --eval-mode code-only for non-UI slices).
- That command runs the
gan-generator → gan-evaluator loop and writes
gan-harness/feedback/feedback-NNN.md until the score passes or plateaus.
- Stop at Gate 1 (slice plan) and Gate 2 (pre-commit). Commit the
scaffold and each slice as separate
feat: commits.
- Add
security-reviewer for any slice touching a security trigger.
Example
orch-build-mvp: civicpulse/docs/SDD-v0.6.md
→ read SDD → slice list (vertical) → scaffold slice 1 [GATE 1: approve]
→ /gan-build --skip-planner (generator → evaluator loop) scores vs spec → review
→ commit feat: [GATE 2: confirm] → next slice
