troubleshoot is a skill for Claude Code from digital-stoic-org/agent-skills. It costs 43 tokens per session (916 once invoked), scanned A, original, MIT.

A search-first workflow for investigating errors, bugs, crashes, and other things that are not working.

In plain words
What is it for?
Use it to troubleshoot software failures by collecting the stack and environment, searching for known solutions, diagnosing the cause, and recording what was learned.
Why use it?
It starts with known lessons and relevant searches, then moves through diagnosis and investigation instead of guessing at a fix.

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

troubleshoot 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 11d 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.

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Troubleshoot

Search-first diagnostic workflow. Human executes commands.

⚠️ AskUserQuestion Guard

CRITICAL: After EVERY AskUserQuestion call, check if answers are empty/blank. Known Claude Code bug: outside Plan Mode, AskUserQuestion silently returns empty answers without showing UI.

If answers are empty: DO NOT proceed with assumptions. Instead:

  1. Output: "⚠️ Questions didn't display (known Claude Code bug outside Plan Mode)."
  2. Present the options as a numbered text list and ask user to reply with their choice number.
  3. WAIT for user reply before continuing.

Workflow

0.Load → 1.Search → 2.Qualify → 3.Diagnose → 4.Investigate → 5.Persist → 6.Learn

0. Load Learnings

Read $PRAXIS_DIR/reference/troubleshoot/learnings.yaml if exists. Apply known patterns before searching.

1. Search (do first)

80% of bugs solved online.

  • WebSearch: [error] [stack] [framework] on SO, GitHub, Docs, Reddit
  • Solution found → skip to 5.Learn

2. Qualify (2-3 questions)

AskUserQuestion:

  • Stack? (language, framework, runtime)
  • Environment? (local, container, cloud)
  • Changed recently? (deploy, config, dependency)

3. Diagnose

See protocols/diagnose.md for details.

  1. Mental models: Check learnings.yaml → WebSearch pattern → reason with 5 Whys/Fishbone
  2. Isolation: Wolf Fence (binary search), swap one variable, minimal repro
  3. Root cause drill: 5 Whys, Fishbone 6 M's

Pattern matches → suggest fix, skip OODA

4. Investigate (OODA)

Only if diagnosis inconclusive.

  • Observe: User runs command, pastes output
  • Orient: Analyze, update hypothesis
  • Decide: Next command or confirm cause
  • Act: Suggest fix (user executes)

Exit when root cause confirmed and fix verified.

5. Persist Thinking Artifact ⚠️ MANDATORY

MUST execute after root cause confirmed and fix verified. DO NOT skip. DO NOT wait for user to ask.

Persist the diagnostic session to $PRAXIS_DIR/thinking/troubleshoot/{project}/{date}-{slug}-llm.md.

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.

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.

troubleshoot is a skill published in the GitHub repository digital-stoic-org/agent-skills (20 stars, last pushed 4d ago), licensed MIT. It adds 43 tokens to every session and 916 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
