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 | $0.00036 | $0.01374 |
| Opus 5 | $0.00018 | $0.00687 |
| Sonnet 5 | $0.00007 | $0.00275 |
| Haiku 4.5 | $0.00004 | $0.00137 |
Grade A, and why
migraciones 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 7d 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 — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: Migraciones en FacturaScripts
Las migraciones permiten ejecutar operaciones sobre datos de la base de datos de forma controlada, una única vez, tras instalar o actualizar un plugin. Se registran en MyFiles/migrations.json para evitar su re-ejecución.
Importante: Las migraciones son para cambios en datos, NO para cambios en la estructura de las tablas. La estructura se gestiona automáticamente mediante los archivos XML en
Table/.
Cuándo usar migraciones
- Rellenar nuevos campos con valores por defecto para registros existentes
- Migrar valores al nuevo formato cuando cambia un campo
- Normalizar datos de versiones anteriores
- Limpiar registros huérfanos o referencias rotas
- Corregir valores incorrectos detectados en versiones anteriores

Paso 1: Crear la clase de migración
<?php
namespace FacturaScripts\Plugins\MiPlugin\Migration;
use FacturaScripts\Core\Template\MigrationClass;
/**
* Rellena el campo 'prioridad' para clientes existentes al actualizar a v1.2.0.
*/
class RellenarPrioridadClientes extends MigrationClass
{
// Identificador único — debe ser descriptivo e incluir versión o fecha
const MIGRATION_NAME = 'rellenar_prioridad_clientes_v1.2.0';
public function run(): void
{
// Siempre verificar que la tabla existe
if (!$this->db()->tableExists('clientes')) {
return;
}
$sql = "UPDATE clientes SET prioridad = 'normal' WHERE prioridad IS NULL OR prioridad = ''";
$this->db()->exec($sql);
}
}
Paso 2: Registrar en Init.php
Las migraciones se ejecutan en el método update() del Init.php:
<?php
namespace FacturaScripts\Plugins\MiPlugin;
use FacturaScripts\Core\Base\InitClass;
use FacturaScripts\Core\Migrations;
class Init extends InitClass
{
public function init(): void
{
}
public function update(): void
{
// Una sola migración
Migrations::runPluginMigration(new Migration\RellenarPrioridadClientes());
// O varias migraciones en orden cronológico
Migrations::runPluginMigrations([
new Migration\FixV1_0_0(),
new Migration\FixV1_1_0(),
new Migration\RellenarPrioridadClientes(),
]);
}
}
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.

migraciones is a skill published in the GitHub repository FacturaScripts/fs-claude-plugin (8 stars, last pushed 5d ago), licensed MIT. It adds 36 tokens to every session and 1,374 once invoked, about $0.0002 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 2026-08-31.
