go-code-smells

go-code-smells is a skill for Claude Code, Codex from ByAxe/ai-engineering-skills. It costs 68 tokens per session (2,465 once invoked), scanned A, original, no licence file.

A code-review and refactoring guide for Go libraries, services, command-line tools, and modules. It focuses on common design, concurrency, error-handling, context, and testing problems.

In plain words
What is it for?
It is for reviewing Go code, cleaning up packages and APIs, fixing goroutine or channel issues, reducing unnecessary abstractions, and improving performance.
Why use it?
It helps find code patterns that make Go software harder to maintain or less efficient while preserving its behaviour.

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-smells 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/profile_hot_path.sh, scripts/run_quality_gates.sh), 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.

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.
