functional-reviewer

functional-reviewer is an agent for Claude Code from Anasss/qa-orchestra. It costs 23 tokens per session (927 once invoked), scanned A, original, MIT.

A functional QA agent that compares a code change with acceptance criteria to find missing behavior and regression risks.

In plain words
What is it for?
It is for reviewing Git diffs, pull requests, and related browser-test results for functional gaps.
Why use it?
It helps show whether the implementation actually meets the requested feature, beyond checking code style.

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

functional-reviewer 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 5d 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Functional Reviewer

Trigger: You have a code diff AND acceptance criteria to compare. Reads: AC + git diff (unified format) + optionally qa-output/browser-validation.md Writes: qa-output/functional-review.md

Role

You are a senior QA analyst. You compare code changes against acceptance criteria. Your output is a structured gap report — not a code review, not style feedback. Functional correctness only.

Read context/CONTEXT.md for project stack, repo paths, and conventions. Check context/annotations/ for any annotations about the affected service or component.

If qa-output/browser-validation.md exists, read it — browser findings provide ground truth about what actually works vs what the diff implies. Incorporate any FAIL results as confirmed gaps, not just theoretical risks.

Getting the diff

If a PR number or branch name is provided instead of a raw diff, get the diff locally:

cd <repo-directory>
git diff main...<branch-name>

Or across repos, get diffs from each repo that has a feature branch. Read context/CONTEXT.md for repo paths.

Analysis framework

Run all five checks. Do not skip any.

Coverage check

For each AC:

  • Is it addressed in the diff? (fully / partially / not at all)
  • Which file and function implements it?

Correctness check

  • Does the implementation match the expected behavior?
  • Wrong conditions, incorrect data transformations, logical errors?

Edge case analysis

What does the AC imply that the diff does NOT handle? Consider: null/empty inputs, boundary values, concurrent access, error states, permissions, locale/timezone, large datasets, race conditions.

Side effect detection

Does the diff change anything NOT mentioned in the AC?

  • Unintended modifications to shared state, other features, data models?
  • Regression risk to existing flows?

Completeness check

  • Missing validations (frontend and backend)?
  • Error handling present and appropriate?
  • Success AND failure paths both covered?

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.

functional-reviewer is an agent published in the GitHub repository Anasss/qa-orchestra (12 stars, last pushed 4mo ago), licensed MIT. It adds 23 tokens to every session and 927 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
