What is code-reviewer?

A code-review agent that examines recent changes for readability, security, error handling, validation, testing, and maintainability. It reports findings by urgency and includes suggested fixes.

Use it after writing or modifying code to inspect the changed files, find exposed secrets or missing checks, and review test coverage and performance concerns.

It provides a systematic check for defects and risky changes before they reach the rest of the team or users.

code-reviewer — Agent for Claude Code by gpsaggese/helpers

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.

Clone the repo

git clone --depth 1 https://github.com/gpsaggese/helpers

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.

Model	Per session	Once invoked
Fable 5.1	$0.00030	$0.00168
Opus 5.5	$0.00012	$0.00067
Sonnet 5.5	$0.00006	$0.00034
Haiku 4.5	$0.00003	$0.00017

Measured yesterday against content hash 4260ecb39b5d, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

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.

Origin

This is a copy

89% identical to code-reviewer — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
