debug

debug is a skill for Claude Code, Codex from silvioventre/lovable-skills. It costs 168 tokens per session (1,184 once invoked), scanned A, original, MIT.

A troubleshooting guide for finding the underlying cause of broken software, from build errors and blank pages to missing data and permission failures.

In plain words
What is it for?
Use it to investigate failed builds, rendering problems, incorrect behavior, stale screens, missing components, data issues, and failing edge functions.
Why use it?
It directs each symptom to the relevant investigation path so that fixes address the actual problem instead of hiding its error message.

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 7d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Debug

Find the root cause, then fix that. A change that makes the error message disappear without explaining why the error happened is not a fix — it relocates the bug.

Route the symptom

Read the user's description and any pasted error, then load the one playbook that owns it. Do not load more than one to start; the playbook will tell you if the trail leads elsewhere.

Symptom Playbook
Build fails, red error banner, syntax or type error reference/build-and-preview.md
Blank page, white screen, nothing renders reference/build-and-preview.md
Preview not found, sandbox stuck spinning up reference/build-and-preview.md
"File exceeds the 10 MB per-file commit limit" reference/build-and-preview.md
No error, but the app does the wrong thing reference/behavior.md
A component or whole section vanished reference/behavior.md
Worked before the last change, broken now reference/behavior.md
State stale, UI not updating after an action reference/behavior.md
Data will not load, empty list, wrong rows reference/backend.md
Edge function failing or not deploying reference/backend.md
"Permission denied", RLS, user sees nothing or too much reference/backend.md
Login, session, or role check misbehaving reference/backend.md
Same error keeps returning, or a new one each fix reference/loops.md
Two or more fix attempts with no progress reference/loops.md
The project feels too tangled to repair reference/loops.md
A monitoring check reported a finding reference/triage.md

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.
