+# 0047 — System prompt no se carga para agentes en _specials/
+
+## Objetivo
+
+El runtime resuelve la ruta del `system_prompt_file` como `agents/<agent-id>/prompts/system.md`,
+pero los agentes especiales (Father Bot, etc.) viven en `agents/_specials/<agent-id>/`. Resultado:
+el system prompt no se carga y el agente usa solo la `description` como prompt.
+
+## Contexto
+
+En `devagents/llm.go:33`, la ruta se construye asi:
+
+```go
+spPath := filepath.Join("agents", a.cfg.Agent.ID, spFile)
+```
+
+Esto produce `agents/father-bot/prompts/system.md` para Father Bot, pero el archivo real esta en
+`agents/_specials/father-bot/prompts/system.md`.
+
+Los logs confirman el problema:
+```json
+{"msg":"failed to load system_prompt_file, using description","path":"agents/father-bot/prompts/system.md"}
+```
+
+**Impacto**: Father Bot opera sin su system prompt completo (369 lineas de instrucciones, pipeline,
+seguridad) y solo usa la description de una linea del config.yaml. Esto degrada severamente su
+comportamiento.
+
+## Arquitectura
+
+- `internal/config/schema.go` — MODIFICAR: agregar campo `ConfigDir` a `AgentConfig`
+- `internal/config/loader.go` — MODIFICAR: poblar `ConfigDir` con el directorio del config
+- `devagents/llm.go` — MODIFICAR: usar `ConfigDir` en vez de hardcodear `agents/<id>`
+
+No hay cambios en `pkg/` (puro). Los cambios son en el loader (impuro) y runtime (impuro).
+
+## Tareas
+
+### Fase 1: Fix
+
+- [ ] 1.1 Agregar campo `ConfigDir string` (no YAML, solo runtime) a `AgentConfig`
+- [ ] 1.2 En `config.Load()`, poblar `ConfigDir` con `filepath.Dir(path)`
+- [ ] 1.3 En `devagents/llm.go`, usar `a.cfg.ConfigDir` para resolver `system_prompt_file`
+
+### Fase 2: Tests
+
+- [ ] 2.1 Test unitario que verifica que `Load()` puebla `ConfigDir`
+- [ ] 2.2 `go build -tags goolm ./...` compila sin errores
+- [ ] 2.3 `go test -tags goolm ./...` pasa sin errores
+
+### Fase 3: Docs
+
+- [ ] 3.1 Cerrar issue, mover a completed
+
+## Ejemplo de uso
+
+Antes (roto):
+```
+config en: agents/_specials/father-bot/config.yaml
+system_prompt_file: prompts/system.md
+resuelve: agents/father-bot/prompts/system.md  ← NO EXISTE
+resultado: usa description como fallback
+```
+
+Despues (correcto):
+```
+config en: agents/_specials/father-bot/config.yaml
+ConfigDir: agents/_specials/father-bot
+system_prompt_file: prompts/system.md
+resuelve: agents/_specials/father-bot/prompts/system.md  ← CORRECTO
+```
+
+## Decisiones de diseno
+
+1. **`ConfigDir` como campo runtime**: no se serializa en YAML (`yaml:"-"`), se puebla
+   automaticamente por el loader. Cero impacto en configs existentes.
+2. **Genérico**: el fix funciona para cualquier agente en cualquier ubicacion, no solo _specials.
+
+## Riesgos
+
+- Bajo riesgo: cambio minimo y auto-contenido. El campo nuevo es backward-compatible.
