Behavioural Capability Standard (BCS)
BCS is an open specification for deterministic, safe, and portable AI capabilities. It defines a consistent structure and behaviour model so capabilities can run predictably across different platforms, agents, and execution environments.
What BCS Defines
The standard describes how a capability declares its behaviour, inputs, outputs, safety rules, determinism guarantees, and lifecycle state. It is designed to support validation, auditability, and safe reuse across systems.
- Portable capability file format
- Behaviour & output structure
- Safety & fallback model
- Validation & conformance layers
- Lifecycle & registry model
Who BCS Is For
Platform & Runtime Teams
Run capabilities consistently across environments.
Capability Authors
Define behaviours in a standardised, portable way.
Governance & Risk Teams
Gain clearer safety boundaries and lifecycle control.
Why This Matters
AI capabilities increasingly operate across multiple systems, platforms, and organisations. BCS provides a shared behavioural model so capabilities can be trusted, validated, and reused without rewrites or ambiguous execution behaviour.
- Predictable behaviour across runtimes
- Stronger safety & validation controls
- Foundation for ecosystem interoperability
