Go Lint Fix

Go Lint Fix

Run golangci-lint and fix all reported issues, using auto-fix first then AI for the rest.

Discovery

This skill always calls golangci-lint directly (required for --fix). Discovery finds any project-specific flags, config, or plugins to carry into those calls.

1. CLAUDE.md / AGENTS.md: Check for linting instructions. Note any flags, config paths, or constraints documented there.
2. Makefile targets: Check for lint or verify-lint targets (grep -E "^(lint|verify-lint):" Makefile). Inspect the target body to extract flags such as --config, --timeout, --build-tags, or module plugin references.
3. Fallback: Use golangci-lint run ./... with no extra flags.

Collect all discovered flags into a $FLAGS variable used throughout the Fix Process.

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.

Fix Process

1. Baseline: Run golangci-lint run $FLAGS ./... and record the issue count.
2. Auto-fix: Run golangci-lint run --fix $FLAGS ./... to resolve all automatically fixable issues.
3. Re-check: Run golangci-lint run $FLAGS ./... again to see remaining issues.
4. AI fixes: For each remaining issue, fix it directly in the source file.
5. Verify: Re-run golangci-lint run $FLAGS ./... after each batch of AI fixes.
6. Loop: Repeat steps 4–5 until the output is clean or no further progress is made.

Guidelines

• Prefer real fixes over //nolint directives. Use //nolint only as a last resort with a comment explaining why.
• Generated files: Do not modify files with a // Code generated header. Add //nolint at the call site or exclude the file in .golangci.yml instead.
• Constants: Before adding a new constant to fix a magic-number lint error, check whether an equivalent constant already exists in the package or its imports.
