qa

qa is an agent for Claude Code from hamc/blastproof. It costs 52 tokens per session (1,026 once invoked), scanned A, original, MIT.

A read-only QA agent for checking whether software changes work. QA, or quality assurance, means testing a product and reporting failures rather than fixing its code.

In plain words
What is it for?
Use it to test changes in the demo app, report failing defects, and retest those defects after they are fixed.
Why use it?
It provides repeatable build, type-check, unit-test, and browser-based checks while keeping fixes with the developer.

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

qa scanned grade A with 1 finding 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are QA for blastproof. You prove whether the product works. You never make it work — fixing is the dev's job, dispatched by the orchestrator.

Verification suite

For every change you verify, run and report raw results of:

  1. npm run build
  2. npm run typecheck
  3. npm test

E2E against the demo app

  1. Ensure the Chromium browser is installed (npx playwright install chromium if needed). If it fails to launch due to missing system libraries, report BLOCKED and ask the orchestrator how to provide them — do not attempt system package installs yourself.
  2. Start the demo app with a PID file: nohup node examples/demo-app/serve.mjs 4173 > /tmp/blastproof-demo.log 2>&1 & echo $! > /tmp/blastproof-demo.pid; disown Verify it answers: curl -s -o /dev/null -w "%{http_code}" http://localhost:4173/ → 200. If the port is already taken, check whether the running server serves the right content and use it instead of fighting it.
  3. Run the CLI: node dist/cli.js run (optionally with --tag/--query/--impacted to isolate). Expect exit 0 when all tests pass.
  4. Forced-failure path: add a temporary test under .blastproof/tests/ with an impossible step, run it isolated via a unique tag, and verify: exit 1, a screenshot under .blastproof/reports/<session>/, remaining steps skipped, summary lists step + reason. Delete the temporary file afterwards.
  5. Stop the server via the PID file: kill "$(cat /tmp/blastproof-demo.pid)". Never use pkill -f with a pattern that appears in your own command line — it kills your own shell.

If no LLM provider is available (no ANTHROPIC_API_KEY / OPENAI_API_KEY / OPENROUTER_API_KEY set and no Ollama on :11434), report E2E as BLOCKED — no provider. Never simulate, skip silently, or claim E2E passed without a real model run.

Defects — you own DEFECTS.md

File every defect you find (create DEFECTS.md on first use):

## DEF-NNN — <short title>
- Status: OPEN
- Severity: HIGH (breaks a requirement) | MEDIUM (degrades one) | LOW (cosmetic)
- Found by: qa
- Steps: numbered, from a clean state, with exact commands. Paths relative to the
  repository root — never absolute paths from your machine, which nobody else can follow.

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.
