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 <area>: <qué>.
  • Path absolutos relativos al repo root (/home/juan/Work/agentforge/).

Phase A — Foundations (Tasks 15)

Task 1: Repository scaffolding y tooling

Files:

  • Create: pyproject.toml

  • Create: Makefile

  • Create: .env.example

  • Create: core/requirements.txt

  • Create: dashboard/requirements.txt

  • Create directorios: core/src/agentforge_core/{api,domain,registry,llm,guardrails,runtime,observability}, dashboard/src/agentforge_dashboard/{pages,components}, agents/incident_analyzer/{versions,examples}, policies/default/versions, data/, tests/{unit,integration,fixtures}

  • Step 1: Crear estructura de directorios y __init__.py

cd /home/juan/Work/agentforge
mkdir -p core/src/agentforge_core/{api,domain,registry,llm,guardrails,runtime,observability}
mkdir -p dashboard/src/agentforge_dashboard/{pages,components}
mkdir -p agents/incident_analyzer/{versions,examples}
mkdir -p policies/default/versions
mkdir -p data
mkdir -p tests/{unit,integration,fixtures/agents,fixtures/policies,fixtures/inputs}

streamlit>=1.38,<2.0
httpx>=0.27,<0.28
pydantic>=2.7,<3.0
PyYAML>=6.0,<7.0
  • Step 5: Crear .env.example

# Observabilidad
LOG_LEVEL=INFO

# Persistencia
DATA_DIR=./data

# URL del core (la usa el dashboard)
AGENTFORGE_CORE_URL=http://core:8000
  • Step 6: Crear Makefile
.PHONY: help install lint format test smoke up down logs clean

help:
	@echo "Targets: install lint format test smoke up down logs clean"

install:
	pip install -r core/requirements.txt -r dashboard/requirements.txt
	pip install pytest pytest-asyncio ruff mypy freezegun

lint:
	ruff check core/src dashboard/src tests
	mypy core/src

format:
	ruff format core/src dashboard/src tests
	ruff check --fix core/src dashboard/src tests

test:
	pytest tests/unit -v

test-all:
	pytest -v

smoke:
	docker compose up -d
	@sleep 5
	curl -fsS http://localhost:8000/health || (docker compose down && exit 1)
	docker compose down

up:
	docker compose up

down:
	docker compose down

logs:
	docker compose logs -f

clean:
	rm -rf .pytest_cache .mypy_cache .ruff_cache __pycache__ data/*.sqlite data/*.jsonl
  • Step 7: Verificar instalación local mínima
cd /home/juan/Work/agentforge
python -m venv .venv
source .venv/bin/activate
pip install -r core/requirements.txt -r dashboard/requirements.txt pytest pytest-asyncio ruff mypy freezegun
ruff check core/src

Expected: All checks passed! (no hay código aún; debe pasar).

  • Step 8: Commit
git add -A
git commit -m "chore: scaffolding inicial del repo (pyproject, requirements, Makefile)"

Phase E — LangGraph Runtime (Tasks 1720)

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 2125)

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 2629)

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 sipmoshss). 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 24api/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.

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 H — Streamlit Dashboard (Tasks 3035)

Streamlit no se testea con unit tests en este MVP (cost/benefit malo). El smoke manual está documentado en docs/manual_qa.md (Task 38).

Nota de implementación (desviación del plan):

  • Task 31: las páginas de Streamlit deben llamarse <n>_<emoji>_<Label>.py para la navegación multipágina, lo que choca con N999 de ruff; se añadió per-file-ignores para dashboard/src/agentforge_dashboard/pages/* en pyproject.toml (commit junto a la página de Registro).
  • Tasks 30-31: se eliminó el # noqa: BLE001 del plan (BLE no está en select, así que RUF100 lo marcaba como noqa inútil); diff_view.py parte el literal HTML largo en dos por legibilidad (E501 está en ignore, no era necesario).
  • Task 32: se omite la variable muerta chosen_example del plan (se asigna directamente a st.session_state["input_text"]).
  • Verificación de cada página: ruff check . + python -m py_compile (no hay unit tests de Streamlit). Los códigos de estado y los nombres de campo se cotejaron contra los modelos del core (AgentDefinition, AgentExecution, GuardrailViolation, PolicyDefinition).

Phase I — Dockerización (Tasks 3637)

Nota de implementación (desviación del plan):

  • Task 36: ambos Dockerfiles pasan docker build --check sin warnings (se usó como lint previo).
  • Task 37 (smoke): docker compose build falló la primera vez en RUN python -m spacy download en_core_web_sm del core — guardrails-ai<0.6 arrastra typer 0.12.x, incompatible con el click 8.3.x que resolvió pip (TypeError: Secondary flag is not valid for non-boolean flag). Se mantuvo el spacy download del plan y se fijó click>=8.1,<8.2 en core/requirements.txt (commit fix(deps): fija click<8.2 …); el rebuild funcionó. Smoke OK: docker compose up -dagentforge-core healthy con GET /health → 200 {"status":"ok"}, agentforge-dashboard con /_stcore/health → ok, sin errores en logs; docker compose down limpio.
  • Walkthrough manual del dashboard (Task 38, ejecutado contra el stack): al recorrer los flujos de docs/manual_qa.md vía la API del core aparecieron tres bugs (que los tests no veían porque el venv local no tiene Presidio y usa la rama de regex): (1) detect_pii instanciaba AnalyzerEngine() sin config → Presidio cargaba su modelo por defecto en_core_web_lg, que no está en la imagen → fail-closed bloqueaba todo → fix fix(guardrails): Presidio usa en_core_web_sm cacheado … (singleton + NlpEngineProvider); (2) el recognizer de PERSON de en_core_web_sm daba falsos positivos sobre los textos de los escenarios → 01_sip/02_mos salían blocked_by_guardrail → fix fix(policies): detect_pii/pii_leakage solo con recognizers de patrón fiables (se quitan PERSON/PHONE_NUMBER); (3) GET /executions solo leía el JSONL (sin las ejecuciones awaiting_approval) → la página de Aprobaciones nunca veía pendientes → fix fix(api): /executions incluye también las ejecuciones HITL pendientes (+ test). Tras los fixes, el walkthrough pasa 26/26: las 5 páginas sirven 200, los 3 escenarios del demo funcionan (MOS→completed, SIP→awaiting→approve→completed / reject→failed), bloqueo PII (NIF/email) OK, historial/violaciones/políticas OK, y el estado sobrevive a down+up.

# 🛡️ 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.

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.

# 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 ┌─────────────────────┐ │ Dashboard (Stream.) │ ───────────► │ Core (FastAPI) │ └─────────────────────┘ └─────────┬───────────┘ │ ┌─────────────────────────┬────────┴──────┬────────────┐ ▼ ▼ ▼ ▼ 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).
  • Step 3: 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.

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.

- [x] **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.
