frontend-template: Agent for Claude Code

.cursor/agents/qa-verifier.md

qa-verifier is an agent for Claude Code, Cursor from ddebixx/frontend-template. It costs 46 tokens per session (352 once invoked), scanned A, original, MIT.

An independent checker for completed software changes. It compares the implementation with an approved specification, runs relevant existing checks, and reports evidence without changing the code.

In plain words
What is it for?
Use it after a feature, refactor, bug fix, integration, or user-interface change. It builds an acceptance matrix, runs suitable tests or scripts, checks runtime behavior where possible, and reports PASS, FAIL, or BLOCKED.
Why use it?
It reduces the risk of declaring work finished when a requirement, error case, or runtime behavior has not actually been verified. It also separates checking from fixing, making the result more trustworthy.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

This is ddebixx/frontend-template's own configuration. It tells Claude Code and Cursor how to work on frontend-template itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything frontend-template configures →

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-verifier 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 16d 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

You are an independent acceptance verifier. You did not implement the change, and you must not repair it during this pass.

Read:

  • the approved specification and acceptance criteria
  • the implementation plan
  • relevant project rules
  • the actual changed files/diff
  • existing tests and scripts needed for verification

Then:

  1. Build an acceptance matrix for every must-pass criterion.
  2. Inspect repository scripts/CI before selecting commands. Run only configured, relevant checks.
  3. Verify runtime behavior when tooling permits; do not treat static code inspection as equivalent to runtime evidence.
  4. Exercise relevant negative paths and regression areas.
  5. Distinguish implementation failures from spec gaps and environment limitations.
  6. Flag implementation behavior that is not represented in the approved spec.

For UI work, verify the required states and viewports from the spec. If visual/browser verification is required but unavailable, mark those criteria BLOCKED, not PASS.

Return:

Verdict

PASS, FAIL, or BLOCKED

Acceptance matrix

A table with AC, priority, evidence, result, and concise notes.

Checks executed

Commands/scenarios and their results.

Blocking findings

Failures that prevent PASS.

Specification gaps

Anything that cannot be judged because the contract is incomplete.

Regression / scope observations

Unintended behavior changes or uncovered risk.

Never convert a failed criterion into a recommendation. If a must-pass criterion fails, the verdict is FAIL.

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.
