go-code-review

go-code-review is a skill for Claude Code from eduardo-sl/go-agent-skills. It costs 0 tokens per session (1,713 once invoked), scanned A, original, MIT.

A structured process for reviewing Go code, with separate approaches for changed lines, whole files or packages, and full codebase audits.

In plain words
What is it for?
Use it for pull-request reviews, package reviews, full audits, and checking code with tools such as go build, go vet, and golangci-lint.
Why use it?
It helps reviewers find correctness, security, maintainability, and style problems consistently, while explaining how serious each finding is.

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

go-code-review 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 12d 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 — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Go Code Review

Structured code review process for Go. Reviews should be constructive, specific, and cite the relevant principle behind each finding.

Operating Modes

Pick the mode that matches the request before starting:

  • Diff review (default) — review only the changed lines plus enough surrounding context to judge them. Use for PRs and working-tree changes.
  • File/package review — review the named files or packages in full, including their tests.
  • Full audit — sweep the entire codebase. Use the strategy in "Auditing Large Codebases" below and aggregate everything into one report.

Review Process

Execute these steps in order. For each finding, classify severity:

  • 🔴 BLOCKER — Must fix before merge. Correctness, data loss, security.
  • 🟡 WARNING — Should fix. Maintainability, idiomatic Go, clarity.
  • 🟢 SUGGESTION — Consider improving. Style, naming, documentation.

0. Run the Toolchain First

Before reading code manually, let the tools catch the mechanical issues (skip any tool that is not installed and note it in the report):

go build ./...          # it must compile
go vet ./...            # suspicious constructs
golangci-lint run       # if the repo has a config
go test -race ./...     # tests pass, no data races

Report tool findings alongside manual findings — a failing go vet is an automatic 🔴 BLOCKER. Never report an issue a tool already proves absent.

Verify Before Reporting

A finding that is wrong costs the author time and the reviewer trust. Before writing one up:

  • Follow the diff outward. Read the callers of a changed function and the callees it now relies on (the go-semantic-tools skill finds them by type, not by name). A bug can live outside the diff yet be triggered by it — and a "bug" inside it can be unreachable because a caller already guarantees the precondition.
  • Lower severity for upstream guarantees, don't drop the finding. A nil dereference behind a constructor that never returns nil is a 🟢 SUGGESTION to make that contract explicit, not a 🔴 BLOCKER.
  • Ask when intent is unclear rather than asserting a bug — "is retries meant to include the first attempt?" beats a wrong fix.
  • Propose a check, not just an opinion. Where a linter, a vet analyzer or a test could catch the issue next time, name it.

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.

go-code-review is a skill published in the GitHub repository eduardo-sl/go-agent-skills (83 stars, last pushed 11d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,713 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 2026-08-30.
