# ADK 2.x Cheatsheet
|
|
|
|
Comandos, schemas YAML, gotchas. **Versión pineada del template: `ibm-watsonx-orchestrate==2.1.0`**.
|
|
|
|
> `./scripts/check-adk-version.sh` te avisa si hay versión nueva en PyPI.
|
|
|
|
## Setup del ADK
|
|
|
|
```bash
|
|
python3.12 -m venv .venv-wxo
|
|
source .venv-wxo/bin/activate
|
|
pip install --upgrade "ibm-watsonx-orchestrate==2.1.0"
|
|
orchestrate --version # debe imprimir 2.1.x
|
|
```
|
|
|
|
## Environments
|
|
|
|
```bash
|
|
# Registrar tenant
|
|
orchestrate env add -n mi-tenant \
|
|
--iam-url https://iam.cloud.ibm.com/identity/token \
|
|
-u "$ORCHESTRATE_API_URL"
|
|
|
|
# Activar (pide API key, lo guarda en keyring)
|
|
orchestrate env activate mi-tenant
|
|
|
|
# Listar
|
|
orchestrate env list
|
|
|
|
# Borrar
|
|
orchestrate env remove -n mi-tenant
|
|
```
|
|
|
|
## Modelos disponibles
|
|
|
|
```bash
|
|
orchestrate models list # todos
|
|
orchestrate models list | grep gpt-oss # filtro
|
|
```
|
|
|
|
**Preferred para tool-calling:** `groq/openai/gpt-oss-120b`
|
|
**Fallback:** `meta-llama/llama-3-3-70b-instruct` (con caveat — ver `known-issues.md`)
|
|
|
|
## Conexiones
|
|
|
|
```bash
|
|
# Crear
|
|
orchestrate connections add -a mi_app
|
|
|
|
# Configurar tipo (key_value | api_key | bearer | oauth2)
|
|
# IMPORTANTE: hacerlo en draft Y live
|
|
orchestrate connections configure -a mi_app --env draft --type team --kind key_value
|
|
orchestrate connections configure -a mi_app --env live --type team --kind key_value
|
|
|
|
# Credenciales
|
|
orchestrate connections set-credentials -a mi_app --env draft -e "BASE_URL=https://..."
|
|
orchestrate connections set-credentials -a mi_app --env live -e "BASE_URL=https://..."
|
|
|
|
# Para API key con header custom (estilo Dun):
|
|
orchestrate connections set-credentials -a mi_app --env draft \
|
|
-e "X_API_KEY=secreto" -e "API_KEY_HEADER=X-Orchestrate-Token"
|
|
|
|
# Listar
|
|
orchestrate connections list
|
|
```
|
|
|
|
## Tools
|
|
|
|
### Python `@tool`
|
|
|
|
```bash
|
|
orchestrate tools import -k python \
|
|
-f wxo/tools/python/mi_tool.py \
|
|
-r wxo/tools/python/requirements.txt \
|
|
--app-id mi_app
|
|
```
|
|
|
|
Cada función decorada con `@tool(...)` se descubre y registra. Si tu
|
|
archivo tiene 6 funciones decoradas → 6 tools.
|
|
|
|
### OpenAPI
|
|
|
|
```bash
|
|
orchestrate tools import -k openapi \
|
|
-f wxo/tools/openapi/mi_spec.yaml \
|
|
--app-id mi_app
|
|
```
|
|
|
|
Pre-requisitos del spec:
|
|
- OpenAPI 3.0 o 3.1
|
|
- `description` per-operation (no solo `summary`)
|
|
- `security` per-operation (no global)
|
|
- `servers[0].url` apuntando al host correcto (patch en deploy time)
|
|
|
|
### MCP
|
|
|
|
```bash
|
|
orchestrate connections add -a mi_mcp_app
|
|
orchestrate connections configure -a mi_mcp_app --env draft --type team --kind mcp
|
|
orchestrate connections set-credentials -a mi_mcp_app --env draft \
|
|
-e "MCP_SERVER_URL=https://mi-mcp-server.example.com"
|
|
```
|
|
|
|
ADK descubre las tools del MCP server automáticamente.
|
|
|
|
## Knowledge bases
|
|
|
|
```bash
|
|
orchestrate knowledge-bases import -f wxo/knowledge_base/mi_kb.kb.yaml
|
|
orchestrate knowledge-bases list
|
|
```
|
|
|
|
Schema YAML mínimo:
|
|
```yaml
|
|
spec_version: v1
|
|
kind: knowledge_base
|
|
name: mi_kb
|
|
description: "..."
|
|
documents:
|
|
- "runbooks/runbook-01.txt"
|
|
- "runbooks/runbook-02.txt"
|
|
embeddings:
|
|
model: ibm/slate-125m-english-rtrvr
|
|
```
|
|
|
|
Los paths de `documents` son relativos al directorio del YAML.
|
|
|
|
## Agentes
|
|
|
|
```bash
|
|
# Import (al draft env)
|
|
orchestrate agents import -f wxo/agents/mi_agente.agent.yaml
|
|
|
|
# Deploy a live
|
|
orchestrate agents deploy --name mi_agente --env live
|
|
|
|
# Listar
|
|
orchestrate agents list
|
|
|
|
# Test con fixture
|
|
orchestrate agents test mi_agente --input-file evals/scenarios/test1.json
|
|
```
|
|
|
|
Schema YAML mínimo de un agente:
|
|
```yaml
|
|
spec_version: v1
|
|
kind: native
|
|
name: mi_agente
|
|
display_name: "Mi Agente"
|
|
description: "..."
|
|
style: react
|
|
llm: groq/openai/gpt-oss-120b
|
|
instructions: |
|
|
Eres ...
|
|
collaborators: []
|
|
tools: []
|
|
knowledge_base: []
|
|
starter_prompts:
|
|
is_default_prompts: true
|
|
prompts: []
|
|
```
|
|
|
|
## Canales
|
|
|
|
```bash
|
|
# Web chat
|
|
orchestrate channels create webchat \
|
|
--agent mi_agente \
|
|
--name "Mi Agente - Web"
|
|
|
|
# Listar
|
|
orchestrate channels list
|
|
```
|
|
|
|
El comando imprime el snippet `<script>` con `agentId` y
|
|
`agentEnvironmentId`. Anotalos.
|
|
|
|
**Paso manual obligatorio después:**
|
|
> WxO Console → Settings → Embed Security → **Off**
|
|
|
|
## Runs API (Plan A — webhook to agent)
|
|
|
|
Para que un sistema externo dispare al agente sin pasar por chat:
|
|
|
|
```bash
|
|
# 1. Conseguir IAM bearer token
|
|
curl -s -X POST "https://iam.cloud.ibm.com/identity/token" \
|
|
-H "Content-Type: application/x-www-form-urlencoded" \
|
|
-d "grant_type=urn:ibm:params:oauth:grant-type:apikey&apikey=$ORCHESTRATE_API_KEY" \
|
|
| jq -r .access_token
|
|
|
|
# 2. POST a /v1/orchestrate/runs
|
|
curl -X POST "$ORCHESTRATE_API_URL/v1/orchestrate/runs" \
|
|
-H "Authorization: Bearer $TOKEN" \
|
|
-H "Content-Type: application/json" \
|
|
-d '{
|
|
"agent_id": "<uuid-del-agente-en-live>",
|
|
"message": "Hubo un evento X en el servicio Y..."
|
|
}'
|
|
```
|
|
|
|
Ver `cotemar-poc-n1/mocks/dynatrace/webhook.py` para implementación
|
|
completa (incluye refresh del token, error handling, retry).
|
|
|
|
## Webhooks lifecycle (run completion)
|
|
|
|
WxO puede llamar a tu backend cuando un run termina. Validá la firma:
|
|
|
|
```python
|
|
# Headers a recibir:
|
|
# X-Orchestrate-Timestamp
|
|
# X-Orchestrate-Nonce
|
|
# X-Orchestrate-Signature
|
|
|
|
# HMAC-SHA256(secret, f"{timestamp}.{nonce}.{body}")
|
|
# Tolerancia 300s sobre timestamp
|
|
# 408 si stale, 401 si firma mala
|
|
```
|
|
|
|
Ver `wxo/tools/openapi/_webhook_validator.py` template.
|
|
|
|
## Evaluaciones (CLI nativa)
|
|
|
|
```bash
|
|
# Test individual
|
|
orchestrate agents test mi_agente --input-file scenario.json
|
|
|
|
# Suite (un .json por scenario)
|
|
for f in evals/scenarios/*.json; do
|
|
orchestrate agents test mi_agente --input-file "$f"
|
|
done
|
|
```
|
|
|
|
Output: respuesta del agente + trace de tool calls.
|
|
|
|
## Cleanup
|
|
|
|
```bash
|
|
orchestrate agents remove --name mi_agente
|
|
orchestrate tools remove --name mi_tool
|
|
orchestrate knowledge-bases remove --name mi_kb
|
|
orchestrate connections remove -a mi_app
|
|
orchestrate channels delete --id <channel-id>
|
|
```
|
|
|
|
El template trae `./scripts/reset-wxo.sh` que hace todo en orden.
|
|
|
|
## Gotchas mortales (los que descubrimos pagando)
|
|
|
|
| Síntoma | Causa | Fix |
|
|
|---|---|---|
|
|
| `kid not found` al deployear a live | Connection no existe en live | `connections configure` en `draft` Y `live` |
|
|
| `No description provided` al importar OpenAPI | Falta `description` per-operation | Forzar `description = summary or "..."` |
|
|
| `recursion_limit reached` en runs | >2 tool calls en flow ReAct | Patrón meta-tool |
|
|
| Agent printea tool calls como texto | Llama 3.3 70B drift después del turno 3 | Cambiar a `gpt-oss-120b` + REGLA #0 en prompt |
|
|
| Pydantic 422 en tool input | LLM mandó `"123"` cuando schema espera `int` | `@field_validator(mode="before")` con coerción |
|
|
| `ModuleNotFoundError: wxo.tools._compat` | TRM importa el archivo standalone | Inlinear el shim en cada `tools.py` |
|
|
| Embed widget queda en "Cargando..." | Embed Security ON en WxO | Settings → Embed Security → Off |
|
|
| Coolify Traefik 503 | Healthcheck `wget --spider` falla | Usar `wget -qO-` o `curl -sf` |
|
|
| Traefik default cert en vez de Let's Encrypt | Labels Traefik manuales en compose | Solo `traefik.enable=true` |
|
|
|
