analizar-bug

analizar-bug is a skill for Claude Code from FacturaScripts/fs-claude-plugin. It costs 190 tokens per session (987 once invoked), scanned A, original, MIT.

A Spanish-language workflow for finding and fixing bugs in FacturaScripts plugins. FacturaScripts is business and invoicing software, and a plugin is an add-on that extends it.

In plain words
What is it for?
Use it when a FacturaScripts plugin behaves incorrectly, produces unexpected data, or needs its error investigated and covered by a test.
Why use it?
It helps distinguish an actual defect from expected framework behavior and guides the investigation toward the underlying cause.

Token cost

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.

Security

Grade A, and why

analizar-bug 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 8d 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.

Skill: analizar-bug — Localización y corrección de bugs en FacturaScripts

Esta skill orquesta los agentes especializados para localizar, entender y corregir bugs en plugins de FacturaScripts de forma sistemática, garantizando que la corrección sea coherente con los patrones del framework y quede cubierta por un test.

Por qué usar agentes en lugar de investigar directamente

Cuando hay un bug, la tentación es leer el código directamente y arreglarlo. Pero sin el contexto del framework es fácil:

  • Confundir comportamiento correcto de FacturaScripts con el bug
  • Arreglar el síntoma sin entender la causa raíz
  • Introducir una corrección que rompe otro comportamiento del framework
  • Escribir el test de verificación sin conocer los patrones de test del ERP

Los agentes especializados evitan estos errores porque conocen los patrones del ERP.

Flujo de análisis de bugs

Paso 1 — Entender el comportamiento esperado (docs-expert)

Antes de mirar el código incorrecto, entender qué debería hacer según el framework:

Agente: docs-expert
Tarea: ¿Cómo debería funcionar [módulo/clase afectado] en FacturaScripts?
       Busca documentación sobre [concepto involucrado: Asiento, Ejercicio, Subcuenta,
       getSubcuenta, codejercicio, modelo afectado, etc.].

Paso 2 — Analizar y corregir el código (backend-developer)

Con el comportamiento esperado claro, buscar la causa raíz en el código:

Agente: backend-developer
Tarea: Analiza el bug en [archivo/método]. El comportamiento esperado es [X],
       pero el comportamiento real es [Y]. Lee el código en [ruta] y localiza
       la causa raíz. Propón y aplica la corrección mínima necesaria sin
       introducir cambios fuera del alcance del bug.

Paso 3 — Escribir un test que verifique la corrección (testing-expert)

Una vez corregido, un test que habría fallado antes de la corrección y pasa después:

Agente: testing-expert
Tarea: Escribe un test PHPUnit que reproduzca el bug corregido:
       [descripción del caso]. El test debe verificar [comportamiento correcto].
       Añádelo en [archivo de test existente: Test/main/XxxTest.php].
       Sigue los patrones del proyecto: DefaultSettingsTrait, RandomDataTrait,
       LogErrorsTrait y los helpers existentes del test.

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.
