pr-to-go-linter

pr-to-go-linter is a skill for Claude Code, Codex from github/gh-aw. It costs 22 tokens per session (474 once invoked), scanned A, original, MIT.

A process for turning a code pattern fixed in a Go pull request into a custom linter. A linter is a tool that reports specific code problems automatically.

In plain words
What is it for?
Use it to study a pull request, implement a Go analyzer with test fixtures, register it, and run the required tests and builds.
Why use it?
It turns a repeated mistake into a lasting automated check and tests that the check works in the repository.

About the project

GitHub Agentic Workflows is a GitHub CLI extension that lets developers define AI-assisted repository automation in Markdown and run it through GitHub Actions. It is intended for tasks requiring interpretation or reasoning, such as issue triage, pull-request review, CI investigation, documentation maintenance, and dependency analysis. The catalogue entries provide skills and agents for working with these workflows.

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

pr-to-go-linter 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 5d 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

PR to Go Linter

Use this skill when a user asks to create a new custom Go linter based on a code pattern fixed in a pull request.

Goal

Convert one concrete PR pattern into a new go/analysis linter under pkg/linters/<name>/ with tests and runner registration.

Inputs

  • Repository owner/name
  • Pull request number
  • Target linter name (kebab-case)

Workflow

  1. Read PR metadata and changed files.
  2. Read the PR diff and extract the repeated pattern that was fixed.
  3. Define one precise diagnostic rule from that pattern.
  4. Confirm no existing linter in pkg/linters/ already covers it.
  5. Implement:
    • pkg/linters/<name>/<name>.go with exported Analyzer
    • pkg/linters/<name>/<name>_test.go using analysistest
    • pkg/linters/<name>/testdata/src/<name>/<name>.go fixtures with // want
    • cmd/linters/main.go registration in multichecker.Main(...)
  6. Validate:
    • go test ./pkg/linters/<name>/...
    • go build ./cmd/linters
    • make golint-custom

Rule quality checks

  • High signal, low false positives on this repository.
  • Diagnostic is specific and fixable.
  • Rule scope matches code in the PR (do not generalize beyond evidence).
  • Do not change unrelated linter packages.

Example pattern source

For PR #33038 (Refactor pkg mutex sites to use deferred unlocks consistently), derive a linter idea that reports lock/unlock sections that manually unlock instead of deferring unlock immediately after lock when the function body matches the same cache/logger-style critical section pattern.

Output expectations

  • Minimal implementation-only diff in pkg/linters/<name>/ and cmd/linters/main.go.
  • Tests prove both flagged and non-flagged cases.
  • PR summary explains: source PR, extracted pattern, and why the rule is safe.

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.

pr-to-go-linter is a skill published in the GitHub repository github/gh-aw (5,104 stars, last pushed today), licensed MIT. It adds 22 tokens to every session and 474 once invoked, about $0.0001 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.
