runtime/

Package api defines shared types that cross workflow/activity boundaries in the agent runtime.

Package engine defines workflow engine abstractions for durable agent execution.

Package inmem provides an in-memory workflow engine implementation for tests and local development.

Package temporal implements the loom-mcp workflow engine adapter backed by Temporal (https://temporal.io).

Package hooks implements fan-out hooks for runtime observability and memory.

Package interrupt provides workflow signal handling for pausing and resuming agent runs.

Package memory persists event payloads as generic maps so stores can serialize them uniformly, but runtime and transcript code should interact with the typed payload structs in this file.

Package inmem provides an in-memory implementation of memory.Store for testing and local development.

Package model defines JSON helpers for marshaling and unmarshaling provider message parts.

Package planner defines planner contracts and helper implementations.

Package policy codifies policy evaluation and enforcement for agent runs.

Package prompt contains runtime prompt registry and override resolution logic.

Package rawjson provides a safe raw JSON byte type for workflow boundaries.

Package reminder defines core types for run-scoped system reminders used to provide backstage guidance to planners (safety, correctness, workflow, and context hints).

Package run defines primitives for tracking agent run executions.

Package runlog provides a durable, append-only event log for agent runs.

Package inmem provides an in-memory implementation of runlog.Store.

Package runtime emits cooperative activity heartbeats for long-running planner and tool activities so engine-driven cancellation reaches streaming provider calls promptly instead of after the activity returns on its own.

Package hints provides lightweight, template-based rendering helpers for tool call/result hints.

Package session defines durable session lifecycle and run metadata primitives.

Package inmem provides an in-memory implementation of session.Store.

Package stream provides abstractions for delivering real-time agent execution updates to clients.

Package bridge provides a discoverable entrypoint to wire the runtime hook bus to a stream.Sink without importing the hooks subscriber directly.

Package telemetry integrates runtime events with Clue tracing and metrics.

Package toolerrors provides structured error types for tool invocation failures.

Package tools defines runtime-facing tool metadata and helpers.

Package transcript provides a minimal, provider‑precise ledger that records the canonical conversation needed to rebuild provider payloads (e.g., Bedrock) without leaking provider SDK types into workflow state.

Package retry defines shared types and helpers for producing standardized retryable errors and compact repair prompts used across generated clients.

Package executor provides registry-backed tool execution.

Package provider implements the provider-side Pulse subscription loop for registry-routed tool execution.
