speckit.debug

speckit.debug is a skill for Claude Code, Codex from wedabro/bro-skills. It costs 23 tokens per session (349 once invoked), scanned A, original, MIT.

A structured debugging skill that investigates a software problem by collecting symptoms, testing possible causes, and identifying the specific line of code or configuration that fails.

In plain words
What is it for?
Use it to document expected and actual behavior, error messages, reproduction steps, hypotheses, verification commands, and a proposed fix or implementation plan.
Why use it?
It replaces guesswork with a recorded investigation and explains why the failure happens before proposing 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

speckit.debug 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 6d 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

🎯 Mission

Use scientific methodology to find the root cause of bugs without disturbing the main context of feature development.

📋 Protocol

Phase 1: Symptom Gathering (Symptom collection)

Before starting to code, make it clear:

  • Expected behavior: What is the expected result?
  • Actual behavior: What is the actual result that is happening?
  • Error messages: Specific error logs (paste directly).
  • Reproduction: Specific steps to reproduce the error (required).

Phase 2: Isolation & Hypothesis (Isolation & Hypothesis)

  • Create file .agents/debug/[issue-slug].md to save the investigation log.
  • Hypotheses: "Maybe the error lies in function X because of Y".
  • Use the commands grep , log to verify the hypothesis.

Phase 3: Root Cause Found (Determine the cause)

  • Only end the investigation when the specific line of code/configuration causing the error is found.
  • Explain WHY it fails instead of just saying IT IS ERROR.

Phase 4: Fix Proposal (Proposal to fix errors)

  • Do not correct errors directly in this skill.
  • The output is either a proposed fix or the creation of a gap_plan for speckit.implement to execute.

🚫 Guard Rails

  • NO guessing. Every conclusion must have evidence from logs or code.
  • DO NOT further damage existing code during debugging (use Read-only tools mainly).
  • MUST create a debug log file to save traces.

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.
