What it does

Protheus Locks Deadlocks is an agent skill from thalysjuvenal/advpl-specialist. Use when the user needs to understand, diagnose, or prevent Protheus record locks and deadlocks -- covering RecLock/MsUnlock/SoftLock/LockByName semantics, BeginTran/EndTran transaction scoping, lock leak and deadlock diagnostics (TopMemoStatus, MonitorActiveLocks, DBAccess monitor, SQL Server/PostgreSQL/Oracle lock queries), and prevention patterns (BEGIN SEQUENCE/RECOVER, lock ordering). Also triggers on Portuguese phrasing like "registro travado", "trava de registro", "deadlock", "erro de lock", "travamento no…

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `diagnostics.md`, `patterns-prevention.md` and `reference.md`).

It sits in Databases. It works with Microsoft SQL Server, PostgreSQL and SQL. The repository describes itself as: Plugin para Claude Code especializado em ADVPL e TLPP para desenvolvimento TOTVS Protheus. The licence is MIT.

When your agent uses it

  • The user needs to understand
  • Prevent Protheus record locks and deadlocks -- covering RecLock/MsUnlock/SoftLock/LockByName semantics
  • BeginTran/EndTran transaction scoping
  • Lock leak and deadlock diagnostics (TopMemoStatus

Example prompts

  • “registro travado”
  • “trava de registro”
  • “deadlock”
  • “/protheus-locks-deadlocks”

What it can do on your machine

Read from SKILL.md and the folder at commit d80599b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    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.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Protheus Locks Deadlocks loads about 553 tokens when it runs. Until then it costs about 153 tokens; SKILL.md has 188 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~153
When it runs · the whole SKILL.md, loaded when a task matches
~553

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.

Safety

Auto-check passed

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.

Protheus Locks & Deadlocks

This skill documents the Protheus hybrid locking model -- record-level Workarea locks (RecLock/MsUnlock) coordinated by DBAccess on top of the underlying RDBMS (PostgreSQL, MSSQL, Oracle) -- and how to diagnose and prevent the lock leaks, contention, and deadlocks that are among the most common production issues. It covers lock API semantics (RecLock, MsUnlock/MsUnlockAll, SoftLock, LockByName, TCSqlExec, BeginTran/EndTran/DisarmTransaction), safe transaction scoping with BEGIN SEQUENCE/RECOVER, and live diagnostic procedures per database engine.

Activate this skill when the user reports a "Record locked by user XYZ" error, needs to investigate performance degradation under concurrent load, is writing or reviewing code that locks records, or is designing a batch job over large data sets where lock ordering matters. It does not cover query design or %nolock% usage in Embedded SQL (see query-builder), general runtime/performance debugging unrelated to locking (see advpl-debugging), or BeginSQL/EndSQL macro syntax (see embedded-sql).
