agency-swarm
Agency Swarm is a Python framework for building multi-agent (swarm) applications by defining specialized agents, tool functions (Pydantic-typed), and directional inter-agent communication flows. It is built on top of the OpenAI Agents SDK / Responses API and provides helpers for running demos and persisting thread/state.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
The README suggests using an environment variable (OPENAI_API_KEY) loaded from .env, which is generally safer than hardcoding secrets. However, no explicit security best practices (logging redaction, threat model, or key management guidance) are provided in the supplied content. No information is given about rate-limit handling or safe error/log output.
⚡ Reliability
Best When
You want to orchestrate multiple agent personas/workers within your own Python application using OpenAI-compatible model backends and you can define tools + communication flows in code.
Avoid When
You need an immediately deployable network API (REST/GraphQL) from this package itself, or you cannot supply and manage the required LLM credentials/tokens in your environment.
Use Cases
- • Multi-agent orchestration for task planning and execution (e.g., CEO/Developer/Assistant patterns)
- • Building tool-using agents with validated inputs via Pydantic-based tools
- • Persisting conversation threads across sessions with custom load/save callbacks
- • Generating agent communication topologies using directional communication flows
Not For
- • Projects needing a turnkey hosted service with no backend code
- • Systems requiring strict compliance features that are contractually guaranteed by the framework itself (none stated in provided material)
- • Integrations that require a dedicated REST/GraphQL API surface from Agency Swarm itself
Interface
Authentication
Authentication is implied via setting an OpenAI API key; no first-class OAuth/scoped auth model is described in the provided README.
Pricing
Pricing for the framework itself is not stated (repo appears open-source under MIT). Runtime costs depend on the underlying LLM provider usage.
Agent Metadata
Known Gotchas
- ⚠ No explicit guidance in provided README on retry/idempotency semantics for agent runs.
- ⚠ When orchestrating multiple agents with directional flows, mis-specified flows can cause dead-ends or unexpected delegation loops (not discussed in provided material).
- ⚠ Thread persistence relies on user-provided load_threads_callback/save_threads_callback; incorrect implementations could corrupt state.
