type:debug

Use when the user asks to debug, diagnose, or fix an ADVPL/TLPP error on TOTVS Protheus -- compilation errors (syntax, missing includes, undeclared variables), runtime failures (NIL access, type mismatch, array bounds), performance issues (slow queries, memory leaks), database locks (RecLock timeouts, deadlocks), or AppServer log/crash analysis. Also triggers on Portuguese phrasing like "erro de compilacao", "erro em tempo de execucao", "travou o lock", "RecLock nao libera", "performance lenta", "analisar log do appserver", or a pasted stack trace / error message from Protheus.

From the source SKILL.md

This skill provides a systematic methodology for diagnosing and resolving ADVPL/TLPP errors: a decision flow (compilation vs. runtime), a quick-diagnosis table by symptom, logging tool guidance (Conout, FWLogMsg, ErrorBlock), database lock diagnosis (RecLock/MsUnlock), and quick performance checks (wrong index, array growth in loops, Embedded SQL vs ISAM).

What this skill does

Advpl Debugging is a community-contributed Claude Code skill in the observability sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/advpl-debugging/ and loads when your prompt matches the skill's trigger.
