Module stdlib 

Standard library builtins for the Harn VM.

Modules

agent_state

asset_paths

Re-export of harn_modules::asset_paths plus a VM-side convenience that anchors the project-root walk at the currently-executing source file (via VM_SOURCE_DIR) and falls back to the existing source-relative resolver when the path is not an @-prefixed asset reference.

host

long_running

macros

Support module referenced by #[harn_builtin]-emitted code.

process

secret_scan

template

Prompt-template engine for .harn.prompt assets and the render / render_prompt builtins.

token_redaction

std/oauth/redaction (OA-06) — OAuth token redaction stdlib.

tracing

workflow_messages

Functions

all_builtin_defs

Aggregate of every #[harn_builtin]-emitted VmBuiltinDef in the stdlib.

all_builtin_signatures

Driver-facing helper: flatten the macro-emitted BuiltinDefs into a &'static [&'static BuiltinSignature] slice suitable for harn_builtin_registry::install_builtin_signatures.

register_agent_stdlib

Register agent builtins (requires network access and async runtime).

register_all_macro_builtins

Register every #[harn_builtin]-emitted def on the given VM. Drivers that build the full stdlib via register_vm_stdlib get this for free — each module’s register_*_builtins walks its MODULE_BUILTINS slice. This helper is exposed for embedders / tests that want a one-call entry.

register_core_stdlib

Register core builtins: pure/deterministic, no I/O.

register_io_stdlib

Register I/O builtins (requires OS access).

register_vm_stdlib

Register all standard builtins on a VM (core + io + agent). Also installs the macro-emitted signature slice into the parser registry (idempotent under repeat calls with the same slice pointer).

register_vm_stdlib_with_deferred_llm

Register the stdlib shape used by latency-sensitive CLI execution. Also installs the macro-emitted signature slice into the parser registry.

reset_stdlib_state

Reset thread-local stdlib state. Call between test runs.

stdlib_builtin_metadata

Return discoverable metadata for registered stdlib builtins.

stdlib_builtin_names

Return the canonical list of all stdlib builtin names. Used by harn-lint and harn-lsp to avoid hardcoded duplicate lists.
