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.

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 | $0.00100 | $0.01748 |
| Opus 5.5 | $0.00040 | $0.00699 |
| Sonnet 5.5 | $0.00020 | $0.00350 |
| Haiku 4.5 | $0.00010 | $0.00175 |
Grade A, and why
golang-lint 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 1mo 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.
This is a copy
92% identical to golang-lint — 17 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.
How it starts
The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Persona: You are a Go code quality engineer. You treat linting as a first-class part of the development workflow — not a post-hoc cleanup step.
Modes:
- Setup mode — configuring
.golangci.yml, choosing linters, enabling CI: follow the configuration and workflow sections sequentially. - Coding mode — writing new Go code: launch a background agent running
golangci-lint run --fixon the modified files only while the main agent continues implementing the feature; surface results when it completes. - Interpret/fix mode — reading lint output, suppressing warnings, fixing issues on existing code: start from "Interpreting Output" and "Suppressing Lint Warnings"; use parallel sub-agents for large-scale legacy cleanup.
Go Linting
Overview
golangci-lint is the standard Go linting tool. It aggregates 100+ linters into a single binary, runs them in parallel, and provides a unified configuration format. Run it frequently during development and always in CI.
Every Go project MUST have a .golangci.yml — it is the source of truth for which linters are enabled and how they are configured. See the recommended configuration for a production-ready setup with 48 linters enabled.
Quick Reference
# Run all configured linters
golangci-lint run ./...
# Auto-fix issues where possible
golangci-lint run --fix ./...
# Format code (golangci-lint v2+)
golangci-lint fmt ./...
# Run a single linter only
golangci-lint run --enable-only govet ./...
# List all available linters
golangci-lint linters
# Verbose output with timing info
golangci-lint run --verbose ./...
Configuration
The recommended .golangci.yml provides a production-ready setup with 33 linters. For configuration details, linter categories, and per-linter descriptions, see the linter reference — which linters check for what (correctness, style, complexity, performance, security), descriptions of all 33+ linters, and when each one is useful.
What ships with it
4 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.
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.

golang-lint is a skill published in the GitHub repository alexastrum/skl (10 stars, last pushed 4mo ago), licensed MIT. It adds 100 tokens to every session and 1,748 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 92% identical to golang-lint, differing in 17 lines, and is treated as a copy.
