go-lint

go-lint is a skill for Claude Code from openshift-eng/ai-helpers. It costs 50 tokens per session (493 once invoked), scanned A, original, Apache-2.0.

A read-only Go code check that runs golangci-lint, a collection of checks for mistakes, suspicious code, and inconsistent style, then reports the findings.

In plain words
What is it for?
Use it to lint a Go project, verify code before committing, or inspect and group the reported issues.
Why use it?
It gives you a repeatable way to check code quality without changing project files.

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 →

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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-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 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

Go Lint

Run golangci-lint to check Go code quality and report issues.

Discovery

Find how to run the linter using this cascade — stop at the first match:

  1. CLAUDE.md / AGENTS.md: Check for instructions about linting. If a lint command is documented, use it.
  2. Makefile targets: Check for lint or verify-lint targets (grep -E "^(lint|verify-lint):" Makefile). If found, run make lint or make verify-lint.
  3. Direct invocation: Run golangci-lint run ./...

If golangci-lint Is Not Found

Report that golangci-lint is not available and direct the user to the installation docs. Do not auto-install.

Output

Use this format when issues are found:

Found 15 issues:
- goconst: 5 issues
- staticcheck: 4 issues
- gocyclo: 3 issues
- revive: 3 issues

Example issues:
- pkg/api/handler.go:42: string "application/json" has 3 occurrences (goconst)
- pkg/utils/helper.go:87: cyclomatic complexity 15 of function ProcessData (gocyclo)

When clean:

Code passes all linter checks (0 issues found)

Constraint

This skill is read-only. Never modify files or attempt fixes. Use the golang:lint-fix skill for that.

If the user passes additional flags, chain them to the golangci-lint invocation (e.g., --tests, --concurrency 4).

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.
