agent_events Agent event stream — the ACP-aligned observation surface for the
agent loop. agent_sessions First-class session storage. bridge JSON-RPC 2.0 bridge for host communication. checkpoint Checkpoint system for resilient pipeline execution. connectors Connector traits and shared helpers for inbound event-source providers. event_log events Structured event emission for observability. iter Lazy iterator protocol for the Harn VM. jsonrpc Shared JSON-RPC 2.0 message construction helpers. llm LLM integration: API calls, streaming, agent loops, tool handling, and tracing. llm_config mcp MCP (Model Context Protocol) client for connecting to external tool servers. mcp_card MCP Server Card consumer + publisher (2026 MCP v2.1 spec, harn#75). mcp_registry Process-local MCP server registry for lazy boot + skill-scoped
binding (harn#75). mcp_server MCP server mode: expose Harn tools, resources, resource templates, and
prompts as MCP capabilities over stdio. metadata Project metadata store for Harn’s runtime state root. observability orchestration record_filter runtime_paths schema secrets skills Filesystem-and-host skill discovery for Harn. stdlib Standard library builtins for the Harn VM. stdlib_modules store Persistent key-value store backed by Harn’s runtime state root. tool_annotations Tool annotations — the single source of truth for tool semantics. tracing Pipeline Observability: structured tracing spans with parent/child relationships. triggers trust_graph value visible_text workspace_path AsyncBuiltinChildVmGuard Chunk A compiled chunk of bytecode. CompileError Compile error. CompiledFunction A compiled function (closure body). Compiler Compiles an AST into bytecode. DebugState Information about current execution state for the debugger. HitlHostResponse TriggerPredicateBudget Vm The Harn bytecode virtual machine. Constant A constant value in the constant pool. DebugAction Debug action returned by the debug hook. Op Bytecode opcodes for the Harn VM. HITL_APPROVALS_TOPIC HITL_DUAL_CONTROL_TOPIC HITL_ESCALATIONS_TOPIC HITL_QUESTIONS_TOPIC append_hitl_response clone_async_builtin_child_vm Clone the VM at the top of the async-builtin child VM stack, returning a
fresh Vm instance the caller owns. Enables concurrent tool-handler
execution within a single agent_loop iteration — the VM shares its heavy
state (env, builtins, bridge, module_cache) via Arc/Rc, so cloning is
cheap and each handler gets its own execution context. compile_source Lex, parse, type-check, and compile source to bytecode in one call.
Bails on the first type error. For callers that need diagnostics
rather than early exit, use harn_parser::check_source directly
and then call Compiler::new().compile(&program). install_async_builtin_child_vm json_schema_for_type_expr json_schema_for_typed_params register_http_builtins Register HTTP builtins on a VM. reset_http_state Reset thread-local HTTP mock state. Call between test runs. reset_thread_local_state Reset all thread-local state that can leak between test runs. resolve_module_import_path restore_async_builtin_child_vm Deprecated Legacy no-op retained for backward compatibility. take_async_builtin_child_vm Deprecated Legacy API preserved for out-of-tree callers; new code should use
clone_async_builtin_child_vm(). take/restore serialized concurrent
callers because only one could hold the popped value at a time.
