Advpl Debugging is an agent skill from thalysjuvenal/advpl-specialist. 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…
Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `common-errors.md`, `performance-tips.md` and `reference.md`).
It sits in Development, covering Debugging, Query optimization and Performance optimization. The repository describes itself as: Plugin para Claude Code especializado em ADVPL e TLPP para desenvolvimento TOTVS Protheus. The licence is MIT.
Read from SKILL.md and the folder at commit d80599b. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Advpl Debugging loads about 487 tokens when it runs. Until then it costs about 150 tokens; SKILL.md has 165 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/advpl-debugging/SKILL.md (or your agent's skills folder). This skill also uses 3 other files; get the full folder from GitHub.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).
Activate this skill when the user reports an error message, a stack trace, a compilation failure, a hanging/locked record, a slow routine, or an AppServer crash/log to investigate. It does not cover generating new code from scratch (see advpl-code-generation), a general quality audit of working code (see advpl-code-review), restructuring code that already works correctly (see advpl-refactoring), or converting .prw to .tlpp (see advpl-to-tlpp-migration).
| Reference file | Read when |
|---|---|
| reference.md | Always -- debug methodology flow, quick diagnosis by symptom, logging tools, lock diagnosis, performance quick checks, common debugging mistakes |
| common-errors.md | Looking up a specific compilation or runtime error message (top 50 ADVPL/TLPP errors with cause and fix) |
| performance-tips.md | Investigating a performance bottleneck in depth (query optimization, loop efficiency, memory) |

Advpl Debugging is an agent skill from thalysjuvenal/advpl-specialist. 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.
Advpl Debugging fits situations like: the user asks to debug; fix an ADVPL/TLPP error on TOTVS Protheus -- compilation errors (syntax; missing includes; undeclared variables).
Run `npx skills add thalysjuvenal/advpl-specialist --skill advpl-debugging -a claude-code`. Or copy the skill folder (skills/advpl-debugging in thalysjuvenal/advpl-specialist) into .claude/skills/advpl-debugging in your project. Claude Code loads it when a task matches its description.
Run `npx skills add thalysjuvenal/advpl-specialist --skill advpl-debugging -a codex`. Or copy the skill folder (skills/advpl-debugging in thalysjuvenal/advpl-specialist) into .agents/skills/advpl-debugging in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add thalysjuvenal/advpl-specialist --skill advpl-debugging -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/advpl-debugging, .gemini/skills/advpl-debugging, .github/skills/advpl-debugging and .opencode/skills/advpl-debugging in your project.
SKILL.md names no scripts, command-line tools or credentials: Advpl Debugging is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Advpl Debugging is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 487 tokens (SKILL.md is roughly 1.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
