orch-build-mvp

Turn a design or requirements document into a working MVP, a minimal product, through small end-to-end feature slices. It coordinates scaffolding, repeated generation and evaluation, reviews, and approval gates, with separate commits for the scaffold and each slice.

OriginalShow the original description

Orchestrate bootstrapping a working MVP from a design or spec document — ingest the SDD/PRD, plan thin vertical slices, scaffold the first end-to-end slice, then drive a generator-evaluator build loop with review and gated feat commits. Use when a design or spec document must become a running MVP through planned vertical slices.

Good for

  • Building a working MVP from a design document
  • Planning small end-to-end feature slices
  • Scaffolding the first working feature
  • Reviewing and committing features through approval gates

Overview

What it does

This skill guides the work of turning a design or requirements document into an MVP, a minimal working product. It extracts scope, settled decisions, and the feature list, then divides the work into small feature slices that each support a complete path from start to finish. It scaffolds the first slice and coordinates repeated generation and evaluation, review, and approval. The scaffold and each feature slice receive separate feat: commits.

When it helps

Use it when you have an SDD or PRD but have not decided where to begin building the product. It supports getting one user path working first, adding features afterward, and using evaluation results to guide implementation.

Example requests

  • “Break this PRD into small feature slices and build an MVP with the first complete path working.”
  • “Read this design document and take the first feature through scaffolding, evaluation, and review.”

Notes

Supply the document path as an argument. The skill uses the shared orch-pipeline, an existing GAN harness, and /gan-build. UI evaluation defaults to playwright; non-UI work uses code-only. Approval is required for the feature plan and before committing. Security-related features also involve security-reviewer.

Objective evaluation

AI rated this skill on four points using only the contents of its SKILL.md. Stars and popularity are not taken into account.

Clear instructionsIs it clear when to use it and what it does?
AGoodIt specifies a design document path as input and clearly describes dividing features and building a working MVP.
Concrete stepsAre steps, inputs, outputs, and examples spelled out?
AGoodIt specifies specification and rubric paths, /gan-build arguments, approval gates, and separate commit units.
SafetyAre sending data, deleting files, and running commands disclosed?
AGoodIt requires approval for slice planning and before commits, and adds security-reviewer for security-triggering slices.
Easy setupDoes it need few tools or API keys, and are they documented?
BPartly lackingIt requires orch-pipeline and an existing GAN harness, but does not provide installation instructions.

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

  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.
  3. Stop at Gate 1 (slice plan) and Gate 2 (pre-commit). Commit the scaffold and each slice as separate feat: commits.
  4. 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
