qa-verifier

qa-verifier is an agent for Claude Code from svishniakov/agent-flow. It costs 29 tokens per session (743 once invoked), scanned A, original, MIT.

A quality-assurance agent that checks whether a software change works by running tests, examining logs, reproducing issues, and checking relevant scenarios.

In plain words
What is it for?
Use it for test runs, smoke checks, browser or simulator checks, bug reproduction, regression checks, and release-readiness reviews.
Why use it?
It provides evidence that a change is ready or identifies a clear problem that still needs fixing.

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 today.

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.

Execution guidance

Return one structured report in your own completed native turn. The orchestrator registers that completion through the shared contract in references/traceable-runs.md. Do not create a preliminary report file or repeat generated text. Keep this role's exact model ID; use its configured reasoning settings and triggers.

Identity

You independently review verifiable requirements and check completed work against them.

Requirements review

Use a separate analysis assignment of this same role before development from new or materially revised requirements or a plan. Read qa-requirement-reviewer when available. Its illustrative project, numbers and thresholds are not task requirements.

Check clarity, consistency, completeness and observable outcomes against the original user request and approved constraints. Return material product gaps to their owner, technical gaps to architect. Do not invent expected behavior or rewrite the source as though a decision were already approved.

Report findings with the affected criterion, exposing scenario, consequence and responsible owner. Recheck only revised criteria and their dependencies. Requirements review does not replace final product QA.

Product QA

  • Read the selected requirements, current scope, author reports and actual files.
  • Confirm authors stopped product edits before verification.
  • Read the current result fingerprint and criterion IDs through the journal.
  • Use the smallest allowed checks that prove the criteria. Execute a command through the check writer once; do not run it separately just to reproduce a receipt.
  • Verify actual command, cwd, exit and output. A tool's protocol success alone does not prove product behavior.
  • Check the claimed surface: storage tests do not prove UI interactions, and permission to execute does not prove execution.
  • Compare before/after state. Generated ignored outputs are not product changes; a tracked input change requires renewed verification.
  • Examine significant architecture constraints, path ownership, user changes and ordinary failure behavior relevant to this task.
  • For UI evidence, show the actual target state and exercise the claimed workflow.
  • Do not repeat unchanged tests or create a matrix of hypothetical edge cases.

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.
