​
Framework Registry

The framework field in every /v1/authorize request identifies which agent framework is submitting the intent. Sigil uses this for telemetry, adapter routing, and audit logs. Policy evaluation is framework-agnostic: your warranty.md governs what the agent can do regardless of which framework it runs on.
Two registries, two roles. This page lists agent frameworks: the systems that submit intents. For the registry of conforming signers, the systems that issue Intent Attestations, see the Conformance Registry.

​
Validation

The framework field accepts any non-empty string matching:
  • Lowercase alphanumeric characters and hyphens only
  • Maximum 64 characters
  • Must start with a letter or digit
Unknown framework strings are accepted with a warning log. You are never blocked from authorizing an intent because of an unrecognized framework value.

​
Known Frameworks

​
TypeScript Package

These identifiers are used by the TypeScript integrations. The adapter rows align with the FRAMEWORKS export of @sigilcore/agent-hooks. The mcp-proxy row is implemented by the separate @sigilcore/mcp-proxy package, and the Rust integrations align with the crates listed under Rust Crates below.

​
Rust Crates

sigil-agent-hooks-core can also be used directly from any Rust host. If you are not integrating with IronClaw, keep the default agent-hooks identifier or provide your own custom framework identifier.

​
Using a Custom Framework

If your agent framework is not listed above, use any identifier that follows the validation pattern. Examples:
Custom framework strings pass through to the authorization engine identically to known ones. The only difference is a warning in the server log noting an unrecognized framework. This is informational and does not affect the authorization decision.

​
Machine-Readable Spec

The canonical registry is available as JSON at framework-registry.json for programmatic consumption. It should be kept aligned with the exported FRAMEWORKS surface in @sigilcore/agent-hooks and the Rust crate surface in agent-hooks-rs.
