Skip to main contentWhat 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.
