What Is a Signature

A signature is a typed input/output contract for a model call. In OpenAgents, any decision that gates action should be expressed as a signature.

​
Design Rules

  • Inputs are deterministic facts (task, repo context, budgets, tool outputs)
  • Outputs are machine consumable (enums, booleans, JSON)
  • Decision signatures include confidence and are confidence-gated
  • Outcomes are logged for replay and optimization

​
Plan Mode Signatures (Current)

Plan mode signatures live in crates/dsrs/src/signatures/plan_mode.rs and are exposed via the signature registry:
  • TopicDecompositionSignature
  • ParallelExplorationSignature
  • PlanSynthesisSignature
  • ComplexityClassificationSignature
  • DeepPlanningSignature
  • ResultValidationSignature

​
Registry and UI Exposure

Autopilot Desktop exposes signature metadata via the in‑process registry and WGPUI surfaces. Signature steps and results are rendered directly by the desktop runtime.

​
Why It Matters

Typed signatures make agent behavior inspectable, testable, and swappable. They are the unit of optimization for DSPy and the core of the Guidance and Plan Mode pipelines.
