debug

debug is a skill for Claude Code from whawkinsiv/solo-founder-skills. It costs 47 tokens per session (2,441 once invoked), scanned A, original, MIT.

A systematic workflow for finding why software, tests, or deployments fail. It starts by reproducing the problem and collecting evidence such as code, history, logs, environment settings, and error messages.

In plain words
What is it for?
Investigating reported bugs, failed builds or deployments, test failures, and problems in coding tools such as Claude Code, Lovable, or Replit.
Why use it?
It reduces random fixes and helps identify the underlying cause before changing the code.

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

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 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.

Debug

The golden rule

NO GUESSING. GATHER INFO FIRST.

Bad: Something broke → try random fix → doesn't work → try another → still broken after 5 attempts.

Good: Something broke → reproduce it → gather diagnostic info → diagnose root cause → fix it (usually first try).

Diagnosis before fixes.


Debugging by tool

How you debug depends on which tool you're using.

Claude Code (you have direct access)

Claude Code can gather its own diagnostics. Before asking the founder for screenshots or logs, do this automatically:

Auto-debug steps (do these yourself):
1. Check git history: git log --oneline -10 and git diff HEAD~3
2. Search for the error: Grep for error text across the codebase
3. Read the failing file: Read the file + surrounding context
4. Run the app/tests: Bash to run dev server, test suite, or reproduce
5. Check logs: Read server logs, build output, or error logs
6. Check environment: Verify .env.example vs actual config

Only ask the founder for information you can't get yourself: what they saw in the browser, what they clicked, screenshots of visual bugs.

Lovable / Replit (founder pastes into chat)

The founder needs to gather info manually and paste it. Use the "Tell AI:" prompts in DEBUG-PROMPTS.md — they're structured templates that ensure complete context.

Production bugs (check monitoring first)

Before debugging production issues, check monitoring and error tracking:

1. Error tracker (Sentry, LogRocket): exact error + stack trace + user context
2. Server logs: filter by timestamp of report
3. Hosting dashboard: any deployment or outage at that time?
4. Database: any failed migrations or connection issues?

See /monitor skill for setting up monitoring. See /deploy skill for rollback procedures.


Workflow

Debug process:
- [ ] Reproduce bug consistently
- [ ] Gather diagnostic info (auto in Claude Code, manual elsewhere)
- [ ] Check what changed recently
- [ ] Diagnose root cause before proposing fixes
- [ ] Fix the root cause
- [ ] Test fix works
- [ ] Verify didn't break anything else
- [ ] Ask: how do we prevent this?

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.
