Schemas

The canonical structural definitions for every typed primitive matic writes to disk or moves between actors. Each schema specifies frontmatter fields, file location, and the invariants the runtime enforces — together they form the wire and storage contract that makes the org repo replayable, queryable, and git-auditable. Use these pages when authoring primitives by hand, building adapters, or validating that an integration emits well-formed records.

Agent Message

Internal signal type for direct agent-to-agent communication, threaded against a Work Item or Task and logged to the org Feed.

Context Envelope

The seven-item assembly — Work Item spec, Work Contract, Probes, Memory, Library refs, prior Run records, and grounding sources — snapshotted into every Run for reproducibility.

Decision

Append-only directional choice attached to an entity (org, project, task, work item, or agent), stored in the entity's decisions/ directory and queryable by future agents.

Probe

An agent's self-authored capability, confidence, constraint, preference, or trigger record — the structured self-model that informs routing, staffing, and context assembly.

Run Record

Immutable receipt of a single Work Item execution: mode, timestamps, org git commit hash, context snapshot, agent runtime, output, and Grounding/Coverage check results.

Signal and Payload

The envelope every event enters the runtime through — source, timestamp, typed payload, routing hints, and registry classification — plus the PayloadRefKind rules for typed refs and dedup.

Work Item

The atomic unit of executable work, including the embedded Work Contract (floor, ceiling, coverage mode) that defines what delivery must address and what it must not exceed.
