What is go-code-reviewer?

A review workflow for finding real defects and risks in Go code, a programming language commonly used for services and tools.

It helps review Go changes, pull requests, code quality, regressions, project-rule compliance, and the severity of reported problems.

It makes reviews evidence-based and aligned with the repository's own rules instead of focusing only on style.

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Excessive Agency · line 218
Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.

Fix: Set explicit rate limits, timeouts, and resource quotas for API calls, file operations, and compute. Implement circuit breakers for runaway loops.

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	$0.00045	$0.05905
Opus 5	$0.00023	$0.02952
Sonnet 5	$0.00009	$0.01181
Haiku 4.5	$0.00005	$0.00590

Security

Grade A, and why

go-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 12d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/run_regression.sh, scripts/tests/test_golden_reviews.py, scripts/tests/test_skill_contract.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Go Code Reviewer

Purpose

Use this skill to review Go code for real defects and risk, not just style. The review must be evidence-based, policy-aligned, and actionable.

Quick Reference

When you need to…	Jump to
Select review depth (Lite / Standard / Strict)	§Execution Modes
Read repo policy before reviewing	§Review Policy Sources
Execute full review checklist	§Review Checklist
Determine finding severity	§Finding Severity
Decide what NOT to report	§Review Discipline
Format findings and report	§Output Format
See a complete formatted output example	Load `references/example-output.md`

When To Use

Trigger this skill when the user asks for:

Go code review / PR review / diff review
Code quality or best-practice checks
Risk or regression analysis
"Is this code compliant with project rules?"

Review Policy Sources (in order)

constitution.md (highest repository policy for this skill)
AGENTS.md (repo workflow/testing/style constraints)
Local package conventions (tests, interfaces, dependency patterns)
Go language/runtime best practices If constitution.md is missing, explicitly state that and continue with AGENTS.md + Go best practices.

Execution Modes (Lite / Standard / Strict)

Choose a mode before starting review and state it in the report.

Default mode: Standard
Declare the selected mode in a dedicated Review Mode section. Mode selection rules:
Choose Lite only when scope is small (typically <=3 files), low-risk, and no security/auth/concurrency/public API changes are involved.
Choose Strict when any high-risk signal exists: security/auth, concurrency/lifecycle, HTTP/API contract changes, persistence/schema changes, exported signature changes, or broad refactors (typically >15 files).
Use Standard for everything else.

Lite (fast triage)

Review focus: confirmed defects with high confidence, avoid speculative architecture commentary.
Minimum execution:
- Run at least one static tool (golangci-lint preferred, else staticcheck/go vet).
- Run go test for impacted package(s).
- Run go test -race only if concurrency risk is present; if skipped, state reason.
Baseline/Suppression/SLA gates still apply.
Finding volume: soft target ≤ 5 findings (severity-tiered; see Workflow step 10).

What ships with it

37 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

go-code-reviewer is a skill published in the GitHub repository johnqtcg/awesome-skills (30 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 5,905 once invoked, about $0.0002 per session on Opus 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 2026-08-30.

A workflow that runs a project’s verification skills to produce a report on coding patterns, architecture rules, and project conventions. It is intended for work after implementation, before a pull request, or during code review.

Run the adversarial verification loop — implement, then hand the change to a fresh checker that did not write it, fix what it finds, and re-dispatch until APPROVE. Use before claiming any behavioural change is done, and on requests like "review loop", "adversarial review", "independent review", "get this verified"…
