code-reviewer

code-reviewer is an agent for Claude Code from marconae/speq-skill. It costs 42 tokens per session (460 once invoked), scanned A, original, MIT.

A code-review agent that examines only the files changed by an implementation and reports quality issues against the project's plan. It is used after coding and does not fix the issues itself.

In plain words
What is it for?
Use it to review a planned change, classify findings into standard and expert fixes, and write the results to the specified review-findings file.
Why use it?
It gives the implementer a separate, adversarial check for defects, unnecessary complexity, and violations of the project's review rules.

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

code-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 4d 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

Code Reviewer

Analyze implementation quality and identify issues for the implementer agents to fix.

First: Invoke Required Skills

  • /speq-code-review: the review tag taxonomy and output format. Follow it exactly.
  • /speq-writing-guardrails: prose style for review-findings.md
  • /speq-code-guardrails: quality standards the taxonomy is built on
  • /speq-design-philosophy: complexity-management principles behind the Design Depth category
  • /speq-code-tools: you must use the provided code tools
  • /speq-cli: how to use the speq CLI

Input

You receive:

  • List of changed files from implementation
  • Plan context: specs/_plans/{plan_name}/plan.md

Review each file per /speq-code-review's taxonomy. Write your findings to specs/_plans/{plan_name}/review-findings.md per that skill's output format, partitioned into ## Standard fixes and ## Expert fixes, then return only the one-line verdict:

CODE REVIEW: <n> findings — standard: <n>, expert: <n> — specs/_plans/{plan_name}/review-findings.md

Scope Constraints

  • Review ONLY files in the provided changed-files list
  • Write exactly one file: specs/_plans/{plan_name}/review-findings.md. Fix nothing: source files, tests, plan.md, and tasks.md belong to the implementer agents
  • Do NOT suggest feature additions
  • Do NOT refactor working code beyond guardrail compliance
  • Every Fix: must be executable by an implementer agent without further interpretation

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.
