What it does

Query Builder is an agent skill from thalysjuvenal/advpl-specialist. Use when the user needs to build, choose the pattern for, or optimize a SQL query against Protheus ERP tables -- covering Workarea (DbSelectArea/DbSeek) vs Embedded SQL vs TCSqlExec pattern choice, mandatory DELET/xFilial filters, SIX index-aligned WHERE ordering, FWPreparedStatement parameterization to prevent SQL injection, and cross-database (PostgreSQL/MSSQL/Oracle) portability. Also triggers on Portuguese phrasing like "consulta SQL", "montar query", "otimizar consulta", "qual indice usar", "escolher entre…

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `cross-database.md`, `index-awareness.md` and `patterns-fwpreparedstatement.md`).

It sits in Databases, covering SQL, ORMs and data access and Web application vulnerabilities. It works with SQL, Microsoft SQL Server and PostgreSQL. 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 build
  • Choose the pattern for
  • Optimize a SQL query against Protheus ERP tables -- covering Workarea (DbSelectArea/DbSeek) vs Embedded SQL vs TCSqlExec pattern choice
  • Mandatory DELET/xFilial filters

Example prompts

  • “consulta SQL”
  • “montar query”
  • “otimizar consulta”
  • “/query-builder”

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

Query Builder loads about 594 tokens when it runs. Until then it costs about 148 tokens; SKILL.md has 190 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~148
When it runs · the whole SKILL.md, loaded when a task matches
~594

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 Query Builder

This skill helps build correct, safe, and optimized SQL against Protheus ERP tables, respecting the platform's database conventions: mandatory soft-delete (D_E_L_E_T_) and multi-branch (xFilial) filters, Hungarian-notation field names, dictionary-driven physical schemas (RetSqlName()), and SIX index alignment. It guides the agent to choose the right access pattern -- Workarea navigation vs Embedded SQL vs raw TCSqlExec -- enforce mandatory filters, order WHERE clauses to match available indexes, and parameterize every dynamic value with FWPreparedStatement to eliminate injection risk.

Activate this skill when building any query against Protheus tables (standard SA*/SE*/SF* or custom Z*), deciding between DbSelectArea/DbSeek and Embedded SQL, reviewing code for missing mandatory filters, adding parameterized queries, diagnosing slow queries via index misalignment, or writing cross-database code. It does not cover BeginSQL/EndSQL macro syntax itself (see embedded-sql, its companion skill for macro details), nor record locking semantics during writes (see protheus-locks-deadlocks).

Query Builder fits situations like: the user needs to build; choose the pattern for; optimize a SQL query against Protheus ERP tables -- covering Workarea (DbSelectArea/DbSeek) vs Embedded SQL vs TCSqlExec pattern choice; mandatory DELET/xFilial filters.

How do I install Query Builder in Claude Code?

Run `npx skills add thalysjuvenal/advpl-specialist --skill query-builder -a claude-code`. Or copy the skill folder (skills/query-builder in thalysjuvenal/advpl-specialist) into .claude/skills/query-builder in your project. Claude Code loads it when a task matches its description.

How do I install Query Builder in Codex?

Run `npx skills add thalysjuvenal/advpl-specialist --skill query-builder -a codex`. Or copy the skill folder (skills/query-builder in thalysjuvenal/advpl-specialist) into .agents/skills/query-builder in your project. Codex loads it when a task matches its description.

Can I use Query Builder in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add thalysjuvenal/advpl-specialist --skill query-builder -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/query-builder, .gemini/skills/query-builder, .github/skills/query-builder and .opencode/skills/query-builder in your project.

What does Query Builder need to run?

SKILL.md names no scripts, command-line tools or credentials: Query Builder is instructions for the agent only.
