What it does

Embedded SQL is an agent skill from thalysjuvenal/advpl-specialist. Use when the user needs to write, review, or migrate SQL queries in ADVPL/TLPP using BeginSQL/EndSQL blocks and macro expressions (%table%, %xfilial%, %notDel%, %exp%, %Order%) instead of raw TCQuery string concatenation -- covering INNER/LEFT JOIN patterns, aggregations (SUM/COUNT/GROUP BY/HAVING), subqueries, column type declarations, DML via TCSqlExec, and SQL-injection prevention. Also triggers on Portuguese phrasing like "consulta SQL", "query embutida", "migrar TCQuery para BeginSQL", "escrever SELECT com…

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It sits in Databases, covering SQL. It works with 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 write
  • Migrate SQL queries in ADVPL/TLPP using BeginSQL/EndSQL blocks and macro expressions (%table%
  • %Order%) instead of raw TCQuery string concatenation -- covering INNER/LEFT JOIN patterns
  • Aggregations (SUM/COUNT/GROUP BY/HAVING)

Example prompts

  • “consulta SQL”
  • “query embutida”
  • “migrar TCQuery para BeginSQL”
  • “/embedded-sql”

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

Embedded SQL loads about 509 tokens when it runs. Until then it costs about 144 tokens; SKILL.md has 176 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~144
When it runs · the whole SKILL.md, loaded when a task matches
~509

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.

Embedded SQL in ADVPL/TLPP

This skill covers writing SQL inside ADVPL/TLPP using BeginSQL ... EndSQL blocks and their special macro expressions -- %table:TABLE% for physical table resolution, %xfilial:TABLE% for branch filtering, %notDel% for logical-deletion filtering, %exp:EXPRESSION% for safe variable binding, and %Order:TABLE% for primary-key ordering. It also covers column type declarations, JOIN and aggregation patterns, subqueries, and migrating legacy TCQuery string-concatenation code to Embedded SQL.

Activate this skill whenever the user is writing a new query, reviewing an existing one for correctness/safety, or converting old concatenated-string SQL to the modern BeginSQL syntax. It also covers the restrictions and gotchas of BeginSQL (no * at line start, always include %notDel% and filial filtering, use GetNextAlias(), close aliases) and when to use TCSqlExec instead for INSERT/UPDATE/DELETE.

It does not cover general native function lookups unrelated to SQL (see protheus-reference), business-process context for which tables/fields to query (see protheus-business), or generating documentation for a routine that happens to contain SQL (see documentation-patterns).

When should I use Embedded SQL?

Embedded SQL fits situations like: the user needs to write; migrate SQL queries in ADVPL/TLPP using BeginSQL/EndSQL blocks and macro expressions (%table%; %Order%) instead of raw TCQuery string concatenation -- covering INNER/LEFT JOIN patterns; aggregations (SUM/COUNT/GROUP BY/HAVING).

How do I install Embedded SQL in Claude Code?

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

How do I install Embedded SQL in Codex?

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

Can I use Embedded SQL 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 embedded-sql -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/embedded-sql, .gemini/skills/embedded-sql, .github/skills/embedded-sql and .opencode/skills/embedded-sql in your project.

What does Embedded SQL need to run?

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

Does Embedded SQL access the network?

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.

Is Embedded SQL safe to install?

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.

What licence does Embedded SQL use?

Embedded SQL is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Embedded SQL use?

About 509 tokens (SKILL.md is roughly 2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Embedded SQL?

Skills that share tags, products or a category with Embedded SQL: Evolving The Data Model (TriliumNext/Trilium, 38k stars), SQL Optimization Patterns (ynulihao/AgentSkillOS, 617 stars), SQL Portability (HL7/sql-on-fhir, 150 stars) and DB Migrations (kurealnum/dotfiles, 290 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
