Add Agent

Create a new Agno agent and integrate it into Apollos AI.

Steps

1. Gather Details

Ask the user for:

Agent name (human-readable, e.g., "Research Agent")
Agent ID (slug, e.g., "research-agent")
Description (one-line purpose)
Tools (optional, any Agno tool integrations needed)

2. Create Agent Module

Create backend/agents/{id_with_underscores}.py following this pattern:

from agno.agent import Agent
from agno.guardrails import PIIDetectionGuardrail, PromptInjectionGuardrail

from backend.db import get_postgres_db
from backend.models import get_model

{variable_name} = Agent(
    id="{agent-id}",
    name="{Agent Name}",
    model=get_model(),
    db=get_postgres_db(),
    instructions=["{description}"],
    pre_hooks=[PIIDetectionGuardrail(mask_pii=False), PromptInjectionGuardrail()],
    enable_agentic_memory=True,
    enable_session_summaries=True,
    add_datetime_to_context=True,
    num_history_runs=5,
    markdown=True,
)

Key conventions:

Use get_model() from backend/models.py (never inline LiteLLMOpenAI)
Always pass db=get_postgres_db() for persistent state
Always include guardrails (pre_hooks) — this is mandatory for all agents
Enable agentic memory and session summaries by default

3. Register in main.py

Add the import and include in the agents list:

from backend.agents.{module_name} import {variable_name}

agent_os = AgentOS(
    agents=[knowledge_agent, mcp_agent, {variable_name}],
    ...
)

4. Add Config Entry

Add a quick-prompts entry in backend/config.yaml for the new agent.

5. Add Dependencies

If the agent uses tools that require new packages, add them:

uv add <package>

6. Create Docs Page

Create docs/agents/{id}.mdx with frontmatter, code example, features, and example queries. Add the page to docs/docs.json navigation under the Agents group.

7. Update Documentation

Update these files to reflect the new agent:

README.md — Agents table
PROJECT_INDEX.md — Agents section and core modules
.serena/memories/project-overview.md — Agents list
docs/agents/overview.mdx — Agents table and card group

8. Confirm

Tell the user:

File created at backend/agents/{name}.py
Registered in backend/main.py
Config added to backend/config.yaml
Docs page created at docs/agents/{id}.mdx
Restart needed: mise run docker:up or docker compose restart
