troubleshoot

troubleshoot is a skill for Claude Code from pantheon-org/tekhne. It costs 43 tokens per session (1,609 once invoked), scanned A, original, MIT.

A troubleshooting workflow for errors, bugs, crashes, and failing software. It starts with searching for known solutions, then narrows down the cause using project and environment details.

In plain words
What is it for?
Use it to diagnose errors, qualify failures, inspect recent changes, and record useful fixes for later.
Why use it?
It gives you a repeatable way to investigate problems instead of changing code based on guesses.

    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.

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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 158 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

If a project-level learnings file exists (e.g., learnings.yaml in the project root or a known location), read it and 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 references/protocols/diagnose.md for details.

  1. Mental models: Check learnings file → 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.

If a persistent thinking store is configured (e.g., via an environment variable pointing to a notes directory), write the diagnostic session there. Skip silently if no store is configured.

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 pantheon-org/tekhne (10 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 1,609 once invoked, about $0.0002 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 2026-09-03.
