What it does

Orch Build Mvp is an agent skill from affaan-m/ECC. 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.

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering PRD writing. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

When your agent uses it

  • Spec document must become a running MVP through planned vertical slices
  • Tasks that involve PRD writing

Example prompts

  • “/orch-build-mvp”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Run the orch-pipeline engine with the settings above.
  2. Reuse the existing GAN harness instead of hand-rolling an iterate loop
  3. Stop at Gate 1 (slice plan) and Gate 2 (pre-commit). Commit the
  4. Add security-reviewer for any slice touching a security trigger.

What it can do on your machine

Read from SKILL.md and the folder at commit 2d515e4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Orch Build Mvp loads about 590 tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 220 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~590

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
