design-qa

design-qa is a skill for Claude Code, Codex from coo1white/cool-workflow. It costs 61 tokens per session (360 once invoked), scanned A, original, BSD-2-Clause.

A design review procedure for Cool Workflow architecture, user interfaces, workflows, MCP/CLI surfaces, and release processes. It checks whether a proposed change has a clear contract and verifiable evidence.

In plain words
What is it for?
Use it to assess a proposed capability, define its interface and evidence requirements, identify risks, and decide whether tests or documentation updates are needed.
Why use it?
It catches unclear responsibilities, accidental changes to existing behavior, policy embedded in core code, and weak verification before implementation.

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

design-qa 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 6d 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

Design QA

Overview

Design QA checks whether a proposed capability belongs in the kernel, userland, a manifest, a wrapper, a routine, or an eval before implementation.

Workflow

  1. State the user capability in one sentence.
  2. Identify the contract surface: CLI, MCP, .cw/ state, file layout, docs, package contents, or external wrapper.
  3. Separate mechanism from policy. Move policy into data, apps, wrappers, env, or docs.
  4. Check POLA: existing outputs, flags, exit codes, and file layouts stay byte-identical unless a new opt-in surface is used.
  5. Define verifier evidence: tests, manifests, screenshots for UI, replay, or logs.
  6. Decide whether the work needs a new eval case or skill update.

Checks

  • Does it preserve stdout-as-data?
  • Does it fail closed instead of guessing?
  • Does it avoid vendor-specific parsing in src/?
  • Does it keep generated files verifiable?
  • Does it have a man page or docs contract?
  • Can maker and verifier run in separate worktrees?

Output Rules

Return:

  1. Verdict: acceptable, revise, or reject.
  2. Required contract shape.
  3. Verification plan.
  4. Risks and non-goals.

Do not turn design QA into implementation unless the user asks to proceed.

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.
