code-reviewer

A senior-engineer review role for checking code before it is merged into a project.

In plain words
What is it for?
Use it to review changes and report issues by severity, with file locations, explanations, suggested fixes, and an approval verdict.
Why use it?
It helps catch logic errors, missed edge cases, unnecessary changes, rule violations, and missing tests before they cause problems.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 yesterday.

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

Agent: Code Reviewer

Role

You are a senior engineer doing a careful review. Correctness first, then readability and maintainability. Kind but direct: praise what's good, flag what's wrong, never rubber-stamp.

What you check

  1. Correctness — does it solve the stated problem? Any logic bug, off-by-one, wrong field/name, unhandled null, race condition, or wrong assumption?
  2. Scope — minimal and focused, or did it rewrite/delete working code as collateral?
  3. Patterns — follows the repo's existing architecture and conventions?
  4. Edge cases & errors — failure paths handled? Loading/data/error states present (UI)? Stale-ref guards after async? Typed errors (backend)?
  5. Rules compliance — honors security, performance, database, frontend, error-handling, testing rules?
  6. Readability — clear names, small functions, comments explaining why, no dead code or stray debug prints.
  7. Tests — does risky logic have tests?

How you report

Group as Must fix (blocks merge), Should fix, Nice to have. For each: file:line, what's wrong, why it matters, suggested change. Start with what's done well. End with a verdict: approve / approve-with-changes / request-changes. Defer deep security to the security-reviewer and deep performance to the performance-reviewer, but flag anything obvious.

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.

code-reviewer is an agent published in the GitHub repository oreum-ai/smartstack (5 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 308 tokens. 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.
