debugging-workflow

debugging-workflow is a skill for Claude Code, Codex from thienanblog/awesome-ai-agent-skills. It costs 43 tokens per session (419 once invoked), scanned A, original, Apache-2.0.

A step-by-step process for investigating failures or unexplained behavior before changing code. It emphasizes reproducing the problem, isolating the smallest failing case, and confirming the cause.

In plain words
What is it for?
Use it to read logs and test output, form and test one hypothesis at a time, and add a regression test when practical. It is intended for unknown causes, not routine fixes with an already confirmed cause.
Why use it?
It prevents guesswork, broad refactoring, and fixes that address symptoms instead of the real problem. It keeps the original business behavior in view while narrowing the investigation.

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

debugging-workflow 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 27d 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 — 34 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Debugging Workflow

Use evidence to locate the failing boundary and fix the cause while preserving business intent.

Delegation

Run in the main conversation by default. Delegation can increase usage: obtain explicit approval for the proposed agent count and scope before using subagents. Reuse that approval within its bounds; ask again before expanding the approved count or scope.

Investigate

  1. Capture the failing command or flow, input, expected behavior, actual result, and relevant environment. Read the error and nearby source before expanding the search.
  2. Reproduce the smallest useful case when practical. If reproduction is unavailable, distinguish what logs or source prove from what remains a hypothesis.
  3. Trace the symptom through the affected boundaries. Choose checks that distinguish plausible causes; independent observations can run together when safe. Avoid stacking speculative fixes.
  4. For a UI failure, inspect the supplied image or rendered state. Annotate a copy only if that makes a material ambiguity easier to resolve.

Read debugging-playbook.md for deeper isolation, flaky failures, or temporary instrumentation. Keep sensitive data out of logs and remove temporary debug code.

Fix and verify

Make the smallest coherent fix, preserving unusual business rules unless evidence shows they are the defect. Avoid unrelated refactors. Add a regression test when it provides durable protection, ideally demonstrating failure before the fix.

Rerun the original failure and affected checks. Complete repository-required checks; broaden only when a remaining risk warrants it and authorization permits. Reuse results that remain valid.

If measurement or test design becomes the main work, consult the relevant specialist guidance directly when available.

Report

Explain the cause, fix, and evidence that the failure is resolved. Include reproduction limits or remaining uncertainty. Record a difficult bug in existing durable docs only when future work would benefit.

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.
