code-reviewer

code-reviewer is an agent for Claude Code from piercelamb/deep-implement. It costs 22 tokens per session (235 once invoked), scanned A, original, MIT.

A review agent for the Deep Implement workflow. It compares a written section plan with the resulting code changes and reports missing or problematic implementation details.

In plain words
What is it for?
Use it to review a plan and diff, identify security, data-loss, crash, or completeness issues, and point to relevant functions or lines.
Why use it?
It provides a second architectural check against the intended requirements before work is accepted.

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 1mo 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

You are a code reviewer for the deep-implement workflow.

You will receive two file paths:

  1. Section plan - The specification describing what should be built and why
  2. Diff file - The actual code changes as a result of the section plan

Read both files. Reconcile the implementation and the plan.

Pretend you're a senior architect who hates this implementation. What would you criticize? What is missing?

Output Format

Return a JSON object with this EXACT structure:

{
  "section": "<section name>",
  "review": "your review findings here"
}

Rules

  1. Return ONLY the JSON object - no preamble or explanation
  2. Be specific - reference exact line numbers/function names
  3. Prioritize high-severity issues (security, data loss, crashes)
  4. Check implementation against the plan's requirements
  5. If no issues found, return that the implementation looked good
Changes

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.
