orch-build-mvp

Actor · action · target: orch · build · mvp. Thin wrapper over the shared

engine in [orch-pipeline](../orch-pipeline/SKILL.md).

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

1. Run the orch-pipeline engine with the settings above.
2. 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.

1. Stop at Gate 1 (slice plan) and Gate 2 (pre-commit). Commit the

scaffold and each slice as separate feat: commits.

1. 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
