mvp-workflow

mvp-workflow is a skill for Codex from kornpng/web-mvp-blueprint-kit. It costs 55 tokens per session (496 once invoked), scanned A, original, MIT.

A guided workflow for turning a rough web-app idea into build-ready documents and implementation tickets. It covers the idea, supporting research, product requirements, technical choices, agent instructions, and tasks.

In plain words
What is it for?
Use it to create an idea brief, research pack, buildable product requirements, technical blueprint, AGENTS.md context, and executable task files.
Why use it?
It gives an underspecified app idea a clear scope and an ordered set of materials for building it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mvp-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

MVP Workflow

Guide the user through the full Web MVP Blueprint workflow.

Workflow

  1. Idea Brief - clarify the first user, problem, smallest useful outcome, and MVP boundary.
  2. Evidence Research - collect competitor, user, pricing, and feasibility evidence.
  3. Buildable PRD - define pages, features, data objects, acceptance criteria, and success metrics.
  4. Technical Blueprint - choose a practical stack and implementation route.
  5. Agent Context - generate AGENTS.md and agent_docs/.
  6. Build Tickets - generate task files that Codex can execute one at a time.

State Check

Inspect the current project before choosing the next step:

Artifact Meaning
docs/IdeaBrief-*.md Step 0 complete
docs/EvidencePack-*.md Step 1 complete
docs/BuildablePRD-*.md Step 2 complete
docs/TechBlueprint-*.md Step 3 complete
AGENTS.md and agent_docs/ Step 4 complete
tasks/*.md Step 5 complete

Routing

  • If no idea brief exists, use $mvp-idea-brief.
  • If idea brief exists but no evidence pack exists, use $mvp-research.
  • If evidence exists but no buildable PRD exists, use $mvp-prd.
  • If PRD exists but no technical blueprint exists, use $mvp-tech-design.
  • If technical blueprint exists but no agent context exists, use $mvp-agent-context.
  • If agent context exists but no task tickets exist, use $mvp-build-tickets.

Rules

  • Keep the user oriented with the current step and next artifact.
  • Ask one question at a time when inputs are missing.
  • Favor small Web MVP scope over broad product ambition.
  • Preserve explicit "Not in MVP" decisions.
  • Do not start implementation until agent context and tickets exist, unless the user explicitly skips planning.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
