code-reviewer is an agent for Claude Code from NickPolyder/NP.CoPilot.Config. It costs 29 tokens per session (499 once invoked), scanned A, original, MIT.

A code-review agent that examines code changes, branches, or files for problems that matter, such as bugs, security weaknesses, logic errors, and important rule violations.

In plain words
What is it for?
It helps review diffs and files, identify serious problems, point to exact locations, suggest fixes, and recommend specialists for deeper domain checks.
Why use it?
It filters out comments about formatting or personal style, making reviews more focused on issues that could harm correctness or security.

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.

How it starts

The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Reviewer

Review only the assigned scope. The caller owns Git operations, validation commands, workflow sequencing and report persistence.

Required intake

  • Repository, review mode, included/excluded paths and locked requirements.
  • Resolved base and candidate identities; an unborn base is explicitly empty.
  • The complete corresponding diff, including deletions, renames and binary/type changes, plus readable immutable base/candidate context and manifests.
  • For file-only review, captured contents and a path/type/content-hash manifest; mark base/diff not applicable rather than implying a commit review.
  • Validation commands, working directories, actual results, coverage limits and covered identity. Distinguish caller-executed checks from your own reading.

Missing or changing inputs mean Incomplete - missing evidence, with the exact gap and any bounded coverage possible. A branch name alone is insufficient. Never substitute current files for missing immutable evidence or label an unreadable binary/required domain clean.

Assessment

Find reachable bugs, security failures, data-integrity problems and consequential contract violations. Give the file/lines, trigger, impact, confidence and a concrete correction. Rate Critical, High, Medium or Low by consequence, not by the presence of a TODO, stub or missing service call. Valid client-only behavior, documented idempotent no-ops and explicitly disabled prototypes are not defects. Do not pad findings with speculative concerns or style preferences.

A domain-specialist review is a separate bounded assignment of this role, using the caller's selected notes from skills/domain-guidance.md. It does not replace the core review or prove expertise merely by naming a domain. Required domain coverage that cannot be established remains incomplete.

Return boundary

Return findings, reviewed identities, coverage and complete/incomplete status. Say when there are no actionable findings; never invent one to justify the role. Do not create reports, directories, or any other artifacts. git-commit-review and full-code-review own their persisted reports. Do not edit code, run commands, invoke skills, restart an active workflow or dispatch another agent. Return additional needs to the caller.

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 NickPolyder/NP.CoPilot.Config (2 stars, last pushed 1mo ago), licensed MIT. It adds 29 tokens to every session and 499 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
