Release: Magpie 🐦

We're thrilled to announce Flock 0.1.0 (codename "Magpie") – the first public release! Magpies are known for their intelligence and ability to collect shiny objects; likewise this release brings together the essential pieces for building smart, modular AI agent systems.

Highlights

✨ Declarative Agent Core

  • Define agents via input / output signatures.
  • Built-in DeclarativeEvaluator turns those specs into GPT-4o calls automatically.

🔌 Plug-in Architecture

  • Modules for output formatting, metrics, memory, and tracing.
  • Tools registered with @flock_tool give agents real-world powers.
  • Routers enable dynamic branching.

🚀 Temporal Integration

  • Toggle enable_temporal=True to run your flock as a durable workflow.
  • Automatic retries, state persistence, and visibility via Temporal Web.

📊 Observability

  • Structured logging with fmtlog.
  • OpenTelemetry spans for every agent hook and workflow stage.

🧪 Testing & CLI Goodies

  • CLI for quick runs: flock run path/to/flock.yaml.
  • REST API & Web UI prototype included.
  • Comprehensive examples in .flock/01-getting-started & .flock/02-core-concepts.

Upgrade Notes

This is a major baseline; future 0.x releases may include breaking changes as we stabilise the API. For production workloads pin the minor version (0.1.*).

Acknowledgements

Huge thanks to the early adopters and the Temporal community for invaluable feedback.

Happy hacking, and welcome to the Flock! 🐣
