Module stdlib 

Standard-library packages user code reaches via import — submilli:crypto / submilli:embedding / submilli:fs / submilli:http / submilli:llm / submilli:secrets / submilli:security / submilli:session / submilli:url / submilli:uuid.

Every package is pure Rust host functions registered directly under its package name; the linker resolves user imports with no Wasm shim modules and no Wasm module instantiation. Host-backed classes initialize their vtables separately for each store.

Modules

agents

submilli:agents — hand work to a sub-agent from inside a Submilli program.

capabilities

Catalog of the semantic-security capabilities the stdlib host functions gate via check_security. This is the single source of truth behind submilli blueprint init, the submilli blueprint capability verbs, and the server’s GET /v1/capabilities, so an operator sees every capability the runtime can gate.

code

Contained workspace navigation and anchor-based editing, gated by existing fs grants.

crypto

submilli:crypto — SHA-2 digests, HMAC, OS randomness, constant-time compare. Pure Rust host functions registered directly under the package name; the string | Uint8Array union params are discriminated host-side.

embedding

submilli:embedding — remote text embeddings from inside a Submilli program.

fs

submilli:fs — agent-facing filesystem library.

git

Capability-controlled Git operations. No subprocesses or guest-visible credentials.

http

submilli:http — agent-facing HTTP client library.

llm

submilli:llm — gated model calls from inside a Submilli program.

secrets

submilli:secrets — policy-gated access to Blueprint-declared secrets.

security

submilli:security — semantic capability check.

session

submilli:session — a key-value store scoped to one session.

shared

Helpers shared across stdlib libraries.

skills

submilli:skills — read the skills a harness offers from inside a Submilli program.

test

Test-authoring package. Deliberately absent from stdlib_package_declarations and install_host_functions: only submilli build test makes it importable (by passing its declaration into the compile and installing it directly), so submilli run rejects import ... from "submilli:test" as not found. submilli:test — the test-authoring package test files import.

url

submilli:url — percent-encoding, query-string codecs, URL parse/build.

uuid

submilli:uuid — v4 / v7 generation + validation.

Structs

Stdlib

The standard library an embedder offers its programs: the core packages every embedder has, plus the OptionalPackages it enables.

Enums

OptionalPackage

A standard-library package that exists only when the embedder provides it.

Functions

install_host_functions

stdlib_package_declarations

The core packages: what Stdlib::core offers.
