Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00143 | $0.00552 |
| Opus 5 | $0.00072 | $0.00276 |
| Sonnet 5 | $0.00029 | $0.00110 |
| Haiku 4.5 | $0.00014 | $0.00055 |
Grade A, and why
query-builder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
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).
| Reference file | Read when |
|---|---|
| reference.md | Always -- database conventions, table/field naming, mandatory filters, pattern-choice overview |
| patterns-workarea.md | Generating record-by-record code with DbSelectArea + DbSeek + RecLock |
| patterns-fwpreparedstatement.md | Building parameterized TCQuery/TCSqlExec, LIKE clauses, INSERT/UPDATE/DELETE |
| index-awareness.md | Choosing/validating an index, ordering WHERE clauses, common SIX key expressions |
| cross-database.md | Using ChangeQuery(), TCGetDB(), DBAccess macros, MSSQL/PostgreSQL/Oracle equivalents |
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

query-builder is a skill published in the GitHub repository thalysjuvenal/advpl-specialist (186 stars, last pushed 19d ago), licensed MIT. It adds 143 tokens to every session and 552 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
