midas-qa

midas-qa is a skill for Claude Code from okuzpe/midas-harness. It costs 72 tokens per session (1,184 once invoked), scanned A, original, Apache-2.0.

A quick quality check for the routes or screens changed by a code branch or pull request. A pull request is a proposed code change submitted for review.

In plain words
What is it for?
Use it to smoke-test changed web pages with a browser tool or changed mobile screens with an emulator or simulator, then report pass, fail, or skipped checks.
Why use it?
It helps catch visible problems and browser console errors before formal project verification, without pretending to replace that final review.

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

midas-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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

midas-qa — Ad-hoc branch QA

Guard + state: <paths.engine>/templates/skill-state-ritual.md (+ AGENTS.md § Safety / Path resolution). Surface: internal (ADR-013) — prefer Phase 7 path-pass; power-user may still type this slash.

Quick QA on what changed — not the formal sprint gate. /midas-verify remains required before /close-sprint for UI sprints.

Does / Does not

Does Does not
Smoke-test routes/screens touched by the diff Write tests to {product}/
Optional evidence in {runs}/qa/qa-adhoc-*.md Emit MIDAS_VERIFY_RESULT (not gate-parsed)
Report pass/fail/skip + console errors in chat Auto-fix failures or pass Phase 8

Prerequisites

  • Dev server running (or user starts after port detect)
  • Web: agent-browser CLI
  • Native (diff touches android/, ios/, app/): Maestro MCP + emulator/simulator

Pre-check (cross-platform):

command -v agent-browser >/dev/null 2>&1 && echo ready || echo missing   # POSIX
Get-Command agent-browser -ErrorAction SilentlyContinue                  # PowerShell
where.exe agent-browser                                                  # cmd

Missing → report install instructions and stop (web QA cannot run).

Procedure

1. Determine scope

  • PR: gh pr view <n> --json files -q '.files[].path'
  • Current/empty: git diff --name-only main...HEAD
  • Named branch: git diff --name-only main...<branch>

2. Map files → routes/surfaces

Pattern Surface
src/app/**, app/** URL paths
src/pages/** Page routes
src/components/**, components/** Pages importing them
android/**, ios/**, app.json Native — Maestro list_devices + launchApp
Layout/global CSS Homepage + one inner page minimum

3. Port and server

Default port from package.json / .env / architecture (usually 3000). If not listening, ask user to start (no auto-start without confirm). agent-browser open http://localhost:<PORT>.

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.
