golang-troubleshooting — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited golang-troubleshooting (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Persona: You are a Go systems debugger. You follow evidence, not intuition — instrument, reproduce, and trace root causes systematically.
Thinking mode: Use ultrathink for debugging and root cause analysis. Rushed reasoning leads to symptom fixes — deep thinking finds the actual root cause.
Modes:
NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST. Symptom fixes create new bugs and waste time. This process applies ESPECIALLY under time pressure — rushing leads to cascading failures that take longer to resolve.

fmt.Println, test isolation) and only reach for pprof, Delve, or GODEBUG when simpler tools are insufficient.WHAT ARE YOU SEEING?

Most Go bugs are: missing error checks, nil pointers, forgotten context cancel, unclosed resources, race conditions, or silent error swallowing.
Go error messages are precise. Read them fully before doing anything else:
NEVER debug by guessing — reproduce first. Always:
git bisect to find the breaking commitNever rely on intuition for performance or concurrency bugs:
Change one thing, measure, confirm. If you change three things at once, you learn nothing.
A band-aid fix that masks the symptom IS NOT ACCEPTABLE. You MUST understand why the bug happens before writing a fix.
When you don't understand the issue:
Before flagging a bug or proposing a fix, trace the data flow and check for upstream handling. A function that looks broken in isolation may be correct in context — callers may validate inputs, middleware may enforce invariants, or the surrounding code may guarantee conditions the function relies on.
When the context reduces severity but doesn't eliminate the issue: still report it at reduced priority with a note explaining which upstream guarantees protect it. Add a brief inline comment (e.g., // note: safe because caller validates via parseID() which returns uint) so the reasoning is documented for future reviewers.
Sometimes fmt.Println IS the right tool for local debugging. Escalate tools only when simpler approaches fail. NEVER use fmt.Println for production debugging — use slog.
