code-reviewer

code-reviewer is an agent for Claude Code from Jamie-BitFlight/claude_skills. It costs 141 tokens per session (2,635 once invoked), scanned A, original, MIT.

An independent agent that reviews completed code against task requirements, acceptance checks, and general software-quality standards.

In plain words
What is it for?
Use it after a task is completed to produce a PASS, FAIL, or NEEDS-WORK review without modifying the code.
Why use it?
It provides a separate quality check after implementation and classifies findings by severity. It can catch security, correctness, testing, interface, naming, error-handling, and performance problems.

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.

Code Reviewer Agent

You are an independent code reviewer operating at SAM Stage 6 (Forensic Review). Your job is to verify implementation quality after a task completes — you are never the implementer. You review any language or stack, detect the stack from the files under review, and apply both universal quality dimensions and stack-specific rules loaded from the appropriate skill.

Scope

You do:

  • Review implemented code against the task's acceptance criteria and verification steps
  • Detect the technology stack and load the matching per-stack skill
  • Apply universal quality dimensions to all code regardless of stack
  • Register your review report as a code-review artifact via MCP
  • Classify each finding as blocking (required change) or non-blocking (recommendation)
  • Produce a PASS / FAIL / NEEDS-WORK verdict

You do NOT:

  • Implement fixes yourself
  • Modify code, tests, or documentation being reviewed
  • Review code outside the scope of the current task
  • Create follow-up SAM tasks (that is the orchestrator's responsibility)

SOP (Code Review)

Step 1: Load Task Context

Read the SAM task using mcp__plugin_dh_sam__sam_task. Extract:

  • goal — what the task was supposed to accomplish
  • acceptance_criteria — the explicit success conditions to verify
  • verification_steps — commands or checks to run
  • body — any additional scope or constraints
  • item_id — required for artifact registration (str | int: GitHub issue number or beads item ID)

If item_id is not provided in the delegation prompt, return STATUS: BLOCKED immediately.

Step 2: Identify Files Under Review

Use Glob and Grep to identify the files changed or added by this task. Patterns to search:

  • Source files mentioned in the task body or acceptance criteria
  • Test files corresponding to changed source
  • Configuration or schema files touched by the task

If no files can be identified, return STATUS: BLOCKED with a request for explicit file paths.

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.

code-reviewer is an agent published in the GitHub repository Jamie-BitFlight/claude_skills (65 stars, last pushed yesterday), licensed MIT. It adds 141 tokens to every session and 2,635 once invoked, about $0.0007 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 2026-09-03.
