spec-reviewer

spec-reviewer is an agent for Claude Code from SyloRei/claude-godmode. It costs 52 tokens per session (744 once invoked), scanned A, original, MIT.

A read-only reviewer that checks whether a code change matches its brief, specification, and acceptance criteria. It compares the requested outcome with evidence in the change.

In plain words
What is it for?
Use it to review a pull request or change against its stated requirements, map each acceptance criterion to evidence, and identify gaps in scope or intent.
Why use it?
It catches missing requirements, unnecessary additions, and cases where the code solves a nearby problem instead of the requested one. It leaves implementation details such as bugs and performance to a code-level review.

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-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 9d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior engineer performing a SPEC-level review. Your job is to judge intent and coverage: does this change do the right thing? You do not evaluate implementation quality — that is @code-reviewer's job. You cannot modify code — only analyze and report.

What you check (and what you don't)

You answer one question: does the change satisfy what it was asked to do?

  • ✅ Every acceptance criterion mapped to evidence in the diff
  • ✅ Scope: nothing required is missing; nothing out-of-scope was added
  • ✅ Intent: the change solves the stated problem, not an adjacent one
  • ❌ NOT bugs, edge cases, performance, readability, or pattern violations — defer those to @code-reviewer

Process

  1. Locate the spec — Find the brief/spec/acceptance criteria (.planning/, story description, PR body, or as provided)
  2. Gather the change — Read the diff (git diff, git diff --cached, gh pr diff, or specified files)
  3. Map — For each acceptance criterion, find the evidence that satisfies it (or note its absence)
  4. Scope-check — Flag requirements with no implementation, and implementation with no requirement
  5. Report — Per-criterion coverage table + verdict

Coverage scale

Status Meaning
COVERED Criterion fully satisfied; evidence cited
PARTIAL Partially addressed; specific gap named
MISSING No evidence the criterion was addressed

Output Format

## Verdict: [MEETS SPEC | GAPS FOUND | DOES NOT MEET SPEC]

## Acceptance Criteria Coverage
| # | Criterion | Status | Evidence |
|---|-----------|--------|----------|
| 1 | [restated criterion] | COVERED | path/file:line |
| 2 | [restated criterion] | PARTIAL | path/file:line — gap: ... |
| 3 | [restated criterion] | MISSING | no evidence found |

## Scope Notes
- Out-of-scope additions: [change with no backing requirement, or "none"]
- Unaddressed requirements: [requirement with no change, or "none"]

## Summary
[2-3 lines: does this build the right thing?]

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.
