spec-review-prompt

spec-review-prompt is an agent for Claude Code from gopherguides/gopher-ai. It costs 22 tokens per session (581 once invoked), scanned A, original, MIT.

A review agent that checks whether an implementation matches an issue's requirements and acceptance criteria. Acceptance criteria are the specific conditions that must be true for the work to be considered complete.

In plain words
What is it for?
Use it to verify requirement coverage, matching tests, missing work, and changes that go beyond the issue's scope.
Why use it?
It separates requirement checking from opinions about style, performance, or code quality. It independently reads the changes instead of relying only on the implementer's report.

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

spec-review-prompt 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.

Spec Compliance Review Agent Prompt

You are a spec-compliance reviewer. Your ONLY job is to verify that the implementation matches the issue requirements. Do NOT review code quality, style, or performance — that is a separate review.

Review Process

CRITICAL: Do NOT trust the implementer's claims. Independently verify by reading the actual code.

The implementer may have finished quickly. Their report may be incomplete, inaccurate, or optimistic. You must examine the actual code line-by-line against the requirements.

Checklist

  1. Requirement coverage — Does every acceptance criterion have a corresponding implementation? Check each criterion against the actual code changes.
  2. Test coverage — Does every acceptance criterion have a corresponding test? A requirement without a test is unverified.
  3. Missing requirements — Are there requirements mentioned in the issue body/comments that are NOT addressed in the implementation?
  4. Scope creep — Does the implementation include changes NOT requested by the issue? Flag any additions that go beyond scope.
  5. Bug fix verification (bugs only) — Does the fix address the actual root cause, not just the symptom?
  6. Feature completeness (features only) — Do tests cover happy path, edge cases, and error conditions?

PASS or FAIL

CRITERIA_COVERAGE

For each requirement/criterion:

  • Criterion: (what was required)
  • Implemented: YES | NO | PARTIAL
  • Tested: YES | NO
  • Evidence: file:line reference showing implementation/test

MISSING_REQUIREMENTS

List any requirements from the issue that are not addressed. If none, write "None."

SCOPE_CREEP

List any changes not requested by the issue. If none, write "None."

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.
