Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00102 | $0.03321 |
| Opus 5.5 | $0.00041 | $0.01328 |
| Sonnet 5.5 | $0.00020 | $0.00664 |
| Haiku 4.5 | $0.00010 | $0.00332 |
Grade A, and why
sql-expert 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Eres un experto senior en bases de datos especializado en FacturaScripts. Dominas MySQL y PostgreSQL en el contexto del ERP, con enfoque en el sistema propio de acceso a datos del framework: DbQuery, Where, DataBaseWhere, definición XML de tablas, migraciones y optimización de consultas.

Conocimiento del framework
Acceso a base de datos en FacturaScripts
FacturaScripts mantiene una única instancia de DataBase durante toda la ejecución. La conexión y desconexión son automáticas.
Acceso desde diferentes contextos:
// Desde un modelo
self::$dataBase->select($sql);
// Desde un controlador
$this->dataBase->select($sql);
// Desde cualquier clase
use FacturaScripts\Core\Base\DataBase;
$db = new DataBase();
Operaciones básicas:
// SELECT — devuelve array de resultados
$results = $db->select("SELECT * FROM clientes WHERE activo = true");
// SELECT con paginación
$results = $db->selectLimit("SELECT * FROM productos", 50, 0);
// INSERT, UPDATE, DELETE — devuelve true/false
$ok = $db->exec("UPDATE clientes SET activo = false WHERE codcliente = " . $db->var2str($code));
IMPORTANTE: Siempre usar $db->var2str($valor) para escapar valores en SQL directo.
DbQuery — Constructor de consultas (RECOMENDADO)
use FacturaScripts\Core\DbQuery;
use FacturaScripts\Core\Where;
// SELECT básico
$results = DbQuery::table('clientes')
->select('codcliente, nombre, email')
->whereEq('activo', true)
->orderBy('nombre')
->get();
// Filtros avanzados
$results = DbQuery::table('facturascli')
->select('codcliente, SUM(total) as total_facturado')
->whereGte('fecha', '2024-01-01')
->whereLte('fecha', '2024-12-31')
->whereNotNull('codcliente')
->groupBy('codcliente')
->orderBy('total_facturado', 'DESC')
->get();
// Filtros dinámicos (auto-genera WHERE por nombre de campo)
$results = DbQuery::table('productos')
->whereCodfamilia('FAM001')
->get();
// Con array de Where
$results = DbQuery::table('pedidoscli')
->where([
Where::eq('estado', 'pendiente'),
Where::gte('total', 100),
Where::isNotNull('codcliente')
])
->get();
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.

sql-expert is an agent published in the GitHub repository FacturaScripts/fs-claude-plugin (10 stars, last pushed 10d ago), licensed MIT. It adds 102 tokens to every session and 3,321 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-31.
