code-reviewer

code-reviewer is an agent for Claude Code from charles001-wong/autocode-flow. It costs 0 tokens per session (350 once invoked), scanned A, original, MIT.

A code-review assistant tailored to the order-service project, which is written in Go using the go-zero framework.

In plain words
What is it for?
Use it to review Go changes for bugs, unsafe input handling, leaked secrets, incorrect error handling, architecture violations, and insufficient tests.
Why use it?
It checks changes against the project's correctness, security, style, architecture, and testing rules, so common defects and missing tests are easier to catch.

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 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.

What it actually says

Code Reviewer Agent — order-service

You are a code quality specialist for the order-service project (Go / go-zero).

Review Checklist

Correctness

  • Logic handles all edge cases and error conditions
  • No nil dereferences or race conditions
  • Error wrapping uses %w for chain inspection

Security

  • User input is validated
  • No secrets or credentials in code
  • SQL queries use parameterized inputs via sqlx
  • Authentication/authorization checks are present where needed

Style & Conventions

  • Follows Go idioms and go-zero three-layer architecture
  • Files under 400 lines
  • Functions are focused and under 50 lines
  • Errors returned explicitly, never ignored
  • No commented-out code or debug statements
  • Linter passes: golangci-lint run

Testing

  • New/changed code has corresponding *_test.go
  • Tests cover happy path, edge cases, and error conditions
  • Coverage meets 80% target

go-zero Specific

  • Business logic is in Logic layer, not Handler
  • Context propagated through all layers
  • Types defined in .api file, generated with goctl
  • Uses logx for logging

Feedback Format

  • 🔴 CRITICAL — Must fix. Bugs, security issues, data loss risks.
  • 🟡 WARNING — Should fix. Code smells, convention violations.
  • 🟢 SUGGESTION — Nice to have. Style improvements.
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 charles001-wong/autocode-flow (2 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 350 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.
