# AgentForge Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Construir AgentForge — plataforma profesional de gobernanza de agentes IA con FastAPI core + Streamlit dashboard, ejecución LangGraph stateful con HITL, guardrails runtime extensibles y versionado tipo Git de prompts y políticas.
**Architecture:** Two-tier. `agentforge-core` (FastAPI :8000) expone API REST; `agentforge-dashboard` (Streamlit :8501) la consume vía HTTP. Strategy pattern (Protocol) para `LLMProvider`, `GuardrailEngine` y `AgentRegistry`. Persistencia mixta: YAML (definiciones humanas), JSON (registry), JSONL (logs append-only), SQLite (checkpoints LangGraph).
**Tech Stack:** Python 3.11, Pydantic v2, FastAPI, LangGraph ≥0.2, Guardrails AI + Presidio, NeMo Guardrails (opt-in), Streamlit, structlog, pytest + pytest-asyncio, Docker + docker-compose.
**Spec:** `docs/superpowers/specs/2026-05-09-agentforge-design.md`
**Convenciones del plan:**
- Comentarios y docstrings en español.
- Type hints completos (mypy strict).
- TDD donde aplica; scaffolding/config/YAML sin tests propios.
- Cada Task termina en commit. Mensajes de commit en estilo `: `.
- Path absolutos relativos al repo root (`/home/juan/Work/agentforge/`).
---
## Phase A — Foundations (Tasks 1–5)
### Task 1: Repository scaffolding y tooling
**Files:**
- Create: `pyproject.toml`
- Create: `Makefile`
- Create: `.env.example`
- Create: `core/requirements.txt`

## Phase D — Guardrails Engine (Tasks 13–16)
### Task 13: GuardrailEngine Protocol
**Files:**
- Create: `core/src/agentforge_core/guardrails/base.py`
- [x] **Step 1: Implementar**
```python
"""Interfaz Protocol del motor de guardrails."""
from __future__ import annotations
from typing import Protocol
from uuid import UUID
from agentforge_core.domain.guardrail import GuardrailViolation
from agentforge_core.domain.policy import PolicyDefinition
class GuardrailEngine(Protocol):
"""Motor de validación. Las violaciones se devuelven; el grafo decide bloquear."""

- [x] **Step 2: Commit**
```bash
git add core/src/agentforge_core/guardrails/base.py
git commit -m "feat(guardrails): añade Protocol GuardrailEngine"
```
---
### Task 14: GuardrailsAIEngine — validadores de entrada y salida
**Files:**
- Create: `core/src/agentforge_core/guardrails/validators.py` (validadores standalone)
- Create: `core/src/agentforge_core/guardrails/guardrails_ai.py` (engine que los compone)
- Create: `tests/unit/test_guardrails_ai.py`
Este es el engine más sustantivo. En lugar de depender de `guardrails.hub` (frágil para tests offline), implementamos validadores nativos que hacen lo mismo que los del hub. Presidio sí se usa para PII (es estándar industria y maneja `ES_NIF`).

## Phase E — LangGraph Runtime (Tasks 17–20)
> **Nota de implementación (desviación del plan):** los nodos del grafo son `async def`, así que se invoca con `await graph.ainvoke(...)`, que el `SqliteSaver` síncrono no soporta. El checkpointing se cambió a **`AsyncSqliteSaver`** expuesto como context manager asíncrono (`async with build_checkpointer(data_dir) as cp: ...`). Consecuencias:
> - `core/requirements.txt` fija `aiosqlite>=0.20,<0.21` (la 0.21 eliminó `Connection.is_alive()`, usado por `langgraph-checkpoint-sqlite` 2.x).
> - `AgentOrchestrator` no guarda el checkpointer en `__init__`; abre uno por llamada sobre `self._data_dir`. El estado igual persiste en `data_dir/checkpoints.sqlite` y un `awaiting_approval` sobrevive a un reinicio.
> - Se añadió `tests/unit/test_runtime_orchestrator.py` (5 tests; el plan no incluía tests del orchestrator).
> - Los bloques de código de Tasks 18-20 abajo son la versión original del plan; la **versión autoritativa es la committeada**. Fases siguientes que usen `build_checkpointer` deben usar el patrón `async with`.
### Task 17: AgentState y nodos de validación
**Files:**
- Create: `core/src/agentforge_core/runtime/state.py`
- Create: `core/src/agentforge_core/runtime/nodes.py`
- Create: `tests/unit/test_runtime_nodes.py`
LangGraph define el estado como `TypedDict`. El reducer `operator.add` sobre `decision_path` permite que cada nodo acumule pasos sin pisar lo previo.

## Phase F — FastAPI Core (Tasks 21–25)
> **Nota de implementación (desviación del plan):**
> - `fastapi`/`uvicorn` no estaban instalados en el venv; se instalaron (`fastapi 0.119.1`, `uvicorn 0.31.1`).
> - Los routers usan el estilo `Annotated[T, Depends(...)]` (sin `Depends()` en defaults) para pasar ruff B008; los aliases (`RegistryDep`, `PolicyStoreDep`, `OrchestratorDep`, `SettingsDep`) viven en `api/deps.py`.
> - El orchestrator (ver Phase E) abre el checkpointer por llamada, así que el helper `_build_graph_for_snapshot` del Task 24 no aplica. En su lugar `AgentOrchestrator` expone un método público `snapshot(agent_def, policy, trace_id) -> AgentExecution | None`; el router `GET /executions/{trace_id}` y los gates de approve/reject lo usan.
> - Tests del core usan `tests/fixtures/policies/default/` (fixture mínima sin validadores) además del agente `incident_analyzer` del Task 23.
> - Se añadieron tests no contemplados en el plan: `test_persistence.py`, `test_api_executions.py`, `test_api_policies_violations.py`, y dos tests de `orchestrator.snapshot()`.
> - Los bloques de código de los Tasks 21-25 son la versión original del plan; la **versión autoritativa es la committeada** (typing mypy-strict, manejo de errores, etc.).

## Phase G — Example Assets + Integration Tests (Tasks 26–29)
> **Nota de implementación (desviación del plan):**
> - **Task 26:** `03_hss_capacity_active_active.txt` se reescribió ligeramente para evitar la subcadena `mos` (presente en "últimos") y que el `MockProvider._select` lo mapee a la respuesta canónica `hss` y no a la de `mos` (el dict se recorre `sip`→`mos`→`hss`). `index.yaml` y `versions/{v1,v2}.yaml` se committearon sin cambios respecto al plan.
> - **Task 27:** la constante `EXAMPLES` quedó en una sola línea (cabe en 100 cols); `tests/integration/__init__.py` ya existía desde el scaffolding inicial (Task 1). La fixture `integration_client` apunta a `agents/` y `policies/` **reales del repo**, no a fixtures de test.
> - **Task 29 Step 2** ("persistir índice de ejecuciones"): ya implementado en el **Task 24** — `api/executions.py` persiste `trace_id → {agent_name, version}` en `data_dir/execution_index.json` vía `_record_execution` / `_load_index` / `_resolve` (nombres distintos a los del plan, comportamiento equivalente; además sobrevive a reinicios). Por eso el commit del Task 29 solo añade el test (`test(integration): resume HITL tras recreación del app …`) y no toca `executions.py`.
> - El estilo del repo es `ruff check` (no `ruff format`); los bloques de código de los Tasks 27-29 son la versión del plan, la **versión autoritativa es la committeada**. `mypy` solo corre sobre `core/src`; los tests de integración llevan `# type: ignore[no-untyped-def]` donde usan la fixture sin tipar.
### Task 26: Incident Analyzer agent — YAMLs y escenarios
**Files:**

- [x] **Step 4: Escenarios de ejemplo**
`agents/incident_analyzer/examples/01_sip_registration_drop.txt`:
```
ALERTA P1 - 02:14 UTC
Cluster: cscf-cluster-aravaca-01
Componente: P-CSCF (IMS core)
Síntoma: caída del 80% de registros SIP en los últimos 4 minutos.
Despliegue reciente: imagen 4.7.2 promovida en ventana de 01:50 UTC.
Tráfico de subscribers: estable hasta el despliegue, posterior bajada abrupta.
Logs: P-CSCF reporta 503 en re-registros y rejected_by_HSS en una fracción no
trivial de las peticiones nuevas.
Necesito hipótesis de causa raíz y plan de actuación con riesgos. Si toca
rollback indícalo y describe cómo revertir sin afectar a las llamadas activas.
```
`agents/incident_analyzer/examples/02_mos_degradation_pool_sbc.txt`:
```
ALERTA P2 - 19:42 UTC
Pool: sbc-pool-borde-norte
Componente: SBC de borde (5 instancias activas)
Síntoma: MOS medio cae de 4.1 a 3.4 durante el pico de las 19:30. ASR estable.
NER ligeramente degradado (-1.5%). El pico coincide con el cambio de horario.
No hay despliegues recientes. Capacidad reportada al 78%. Trazas RTP muestran
jitter creciente en flujos G.711, normales en G.729. Hipótesis a explorar:
saturación de codec o congestión transit network.
Propón análisis y acciones con bajo riesgo primero.
```
`agents/incident_analyzer/examples/03_hss_capacity_active_active.txt`:
```
ALERTA P1 - 03:55 UTC
Pareja HSS: hss-pair-madrid (active-active)
Síntoma: alarma simultánea de capacidad al 92% en ambos nodos. Métricas
de replicación muestran lag bajando a cero (sospechoso) y ratio de
escrituras anormalmente alto en los últimos 10 min.
Sospecha de loop de replicación o split-brain incipiente. Las llamadas en
curso no están afectadas pero los nuevos registros sí están degradándose.
Necesito recomendación urgente con análisis de riesgo. Aislar el enlace de
replicación es opción pero alto impacto: requerirá validar coherencia de la
DB de subscribers tras la operación.

## Phase J — Documentación (Task 38)
### Task 38: README, ARCHITECTURE, futuro y manual_qa
**Files:**
- Create: `README.md`
- Create: `ARCHITECTURE.md`
- Create: `docs/futuro.md`
- Create: `docs/manual_qa.md`
- [ ] **Step 1: `README.md`**
```markdown
# 🛡️ AgentForge
Plataforma profesional de **gobernanza de agentes IA**: catalogación, versionado
de prompts y políticas, guardrails runtime, ejecución stateful con
Human-in-the-Loop, observabilidad y trazabilidad end-to-end.
## ¿Por qué?
Poner agentes IA en producción sin una capa de gobierno produce sistemas
opacos: prompts que cambian sin historial, validaciones inconsistentes,
acciones de alto impacto sin supervisión, sin auditoría de decisiones.
AgentForge aporta el plano de control mínimo que un equipo de plataforma
necesita antes de operar agentes con impacto real.
## Arquitectura
```
┌───────────────────────── docker-compose ──────────────────────────┐
│ │
│ ┌─────────────────────┐ HTTP/JSON ┌────────────────────┐ │
│ │ agentforge-dashboard│ ────────────────► │ agentforge-core │ │
│ │ Streamlit :8501 │ ◄──────────────── │ FastAPI :8000 │ │
│ └─────────────────────┘ └────────────────────┘ │
│ │
│ Strategy pattern (Protocol) para LLMProvider, GuardrailEngine, │
│ AgentRegistry. Persistencia mixta: YAML (definiciones), JSON │
│ (registry), JSONL (logs append-only), SQLite (checkpoints). │
└────────────────────────────────────────────────────────────────────┘
```
Detalles completos en [`ARCHITECTURE.md`](ARCHITECTURE.md).
## Quickstart
```bash
cp .env.example .env
docker compose up
```
Abre [http://localhost:8501](http://localhost:8501).
Funciona out-of-the-box (`LLM_PROVIDER=mock`, sin API keys). Si quieres usar
Azure OpenAI real, edita `.env`.
## Demo guiada (3 pasos)
1. **Registro** → ver `incident_analyzer` y comparar `v1` vs `v2`.
2. **Ejecutar** → seleccionar el escenario `01_sip_registration_drop` y
pulsar *Invocar*. Verás el grafo recorrer validate_input → llm_reason
→ validate_output → propose_actions → approve_gate y pausarse en HITL.
3. **Aprobaciones** → revisar las acciones propuestas (con risk_score y
rollback_plan), aprobar las seguras y comprobar que la ejecución
completa.
## Capacidades implementadas
| Feature | Ubicación |
|---|---|
| Agent Registry | `core/src/agentforge_core/registry/repository.py` |
| Versionado tipo Git | `agents//versions/` + `registry/versioning.py` |
| Guardrails runtime | `core/src/agentforge_core/guardrails/` |
| LangGraph stateful + checkpointing | `core/src/agentforge_core/runtime/` |
| Human-in-the-Loop | nodo `approve_gate` + endpoints `/approve` y `/reject` |
| Observabilidad | `observability/logging.py` (structlog + trace_id) |
| LLM provider abstraction | `core/src/agentforge_core/llm/` |
| Política versionada | `policies/default/versions/v1.yaml` |

# AgentForge — Arquitectura técnica
> Documento "vivo" con las decisiones técnicas. El spec original está en
> [`docs/superpowers/specs/2026-05-09-agentforge-design.md`](docs/superpowers/specs/2026-05-09-agentforge-design.md).
## Visión general
Two-tier:
- `agentforge-core` — FastAPI 8000. Dominio de gobierno, runtime LangGraph,
guardrails y persistencia.
- `agentforge-dashboard` — Streamlit 8501. Cliente HTTP del core.
## Diagrama
```
┌─────────────────────┐ HTTP/JSON ┌─────────────────────┐

└─────────────────────┘ └─────────┬───────────┘
│
┌─────────────────────────┬────────┴──────┬────────────┐
▼ ▼ ▼ ▼
LLM layer Guardrails layer LangGraph State
(Strategy pattern) (Strategy pattern) Runtime JSON+SQL+JSONL
```
## Patrones aplicados
- **Strategy / Plugin**: `LLMProvider`, `GuardrailEngine`, `AgentRegistry`,
`PolicyStore` son `Protocol`s con varias implementaciones intercambiables
vía factory que lee `Settings`.
- **Configuration over code**: agentes y políticas como YAML versionados;
cambios sin redeploy.
- **Fail-closed por defecto**: errores en validadores cuentan como bloqueo.
- **Trazabilidad obligatoria**: `trace_id` UUID propagado por
middleware → structlog → API → JSONL.
## Persistencia
| Capa | Tecnología | Por qué |
|---|---|---|
| Agent Registry | JSON + YAML | Humano lo escribe (YAML); máquina lo cataloga (index.yaml). |
| Versionado | YAML por versión + index.yaml | Diff legible; hash SHA-256 normalizado. |
| Logs de violaciones | JSONL append-only | Inmutable, auditable, fácil de shipear. |
| Logs de ejecuciones | JSONL append-only | Idem. |
| Checkpoints LangGraph | SQLite | Tool right; persistencia entre restarts (HITL). |
## HITL — Patrón
Se usa la API dinámica `interrupt(payload)` de LangGraph ≥0.2 dentro del
nodo `approve_gate`. Sólo pausa cuando hay acciones de alto riesgo
(`risk_score >= threshold` o `requires_approval=True`). El cliente envía
`Command(resume={"approved_action_ids": [...]})` vía
`POST /executions/{trace_id}/approve`.
## Observabilidad
- `structlog` con renderer JSON.
- Middleware FastAPI inyecta `X-Trace-Id` y bind-ea contexto.
- Cada nodo del grafo añade un step a `decision_path` con `duration_ms`.
## Errores
- Azure OpenAI / OpenAI: retry exponencial 1s/2s/4s, fallback opcional, luego
`status=failed`.
- Validador: `fail_closed` por defecto.
- Schema mismatch en LLM output: 1 retry, luego `failed`.
- Checkpoint corrupto: 500 explícito (sin auto-recovery).
## Decisiones pospuestas
Ver [`docs/futuro.md`](docs/futuro.md).

# Roadmap (post-MVP)
- **NeMo Guardrails full**: configuración Colang con KB embedding + dialog rails.
- **Autenticación**: OAuth2/OIDC con MSAL para entornos Azure AD.
- **OpenTelemetry**: spans por nodo del grafo, métricas de violaciones por validador.
- **Multi-tenant**: `tenant_id` aislado por registry, política y datos.
- **Evaluadores LLM-as-judge**: regression suite que ejecuta cada agente
sobre escenarios canónicos y mide deriva.
- **UI de aprobación con SLA**: cola Kanban, reasignación entre operadores,
alertas cuando un HITL rebasa SLA.
- **Persistencia migrable a Postgres + pgvector**: requerido para alta
disponibilidad multi-instance.
- **Esquema de prompts mejorado**: variables tipadas en system_prompt
(Jinja-like), valores por entorno.
- **Promoción explícita draft → active** vía PR/aprobación.

# Smoke manual del dashboard
> Esta lista cubre los flujos no automatizados (Streamlit). Ejecutar tras
> cambios visuales o estructurales del dashboard.
## Setup
```bash
cp .env.example .env
docker compose up -d
sleep 15
```
Abrir [http://localhost:8501](http://localhost:8501).
## 1) Registro
- [ ] Aparece `incident_analyzer` en el desplegable.
- [ ] Detalle muestra version, owner, propósito, guardrails, system_prompt.
- [ ] Tabla de versiones lista `v1` y `v2`.
- [ ] Diff `v1 → v2` muestra cambios coloreados.
## 2) Ejecutar
- [ ] Botones de escenarios cargan texto en el textarea.
- [ ] Invocar `02_mos_degradation_pool_sbc` → status=`completed`, sin HITL,
decision_path con 6 steps.
- [ ] Invocar `01_sip_registration_drop` → status=`awaiting_approval`,
banner amarillo redirige a Aprobaciones.
## 3) Aprobaciones
- [ ] La ejecución pendiente aparece en el desplegable.
- [ ] Cada acción muestra risk_score con color, target y rollback_plan.
- [ ] Aprobar acciones seleccionadas → status=`completed`.
- [ ] Rechazo con razón → status=`failed`, error=`rejected_by_human`.
## 4) Historial
- [ ] Tab "Ejecuciones" lista todas las ejecuciones con summary.
- [ ] Detalle muestra trace + violations.
- [ ] Tab "Violaciones" filtrable por severity.
## 5) Politicas
- [ ] `default` aparece con sus validadores de input/output.
- [ ] Cada validador expandible con su config.
## Bloqueo por PII (input)
- [ ] Pegar `El cliente con NIF 12345678Z reporta caída`.
- [ ] Invocar → status=`blocked_by_guardrail`, violación `DetectPII`.
## Persistencia
- [ ] `docker compose down && docker compose up` → ejecuciones previas
siguen accesibles vía Historial; aprobaciones pendientes siguen
pendientes.
```
- [ ] **Step 5: Commit final**
```bash
git add README.md ARCHITECTURE.md docs/futuro.md docs/manual_qa.md
git commit -m "docs: README, ARCHITECTURE, roadmap futuro y manual de QA del dashboard"
```
---
## Cierre
Estado esperado al terminar todas las tasks:
- `make test-all` pasa (unit + integration).
- `make lint` sin errores.
- `docker compose up` arranca core + dashboard healthy.
- Los 3 escenarios de la demo guiada funcionan en el dashboard.
- 38 commits razonablemente atómicos en la rama.
Si algo falla en el orden de tasks (ej. tests de integración bloqueados por
`_EXECUTION_INDEX`), aplicar el cambio descrito en Task 29 antes y revalidar
las anteriores. Es la única dependencia transversal del plan.
