It does not own tool permissions, +credentials, effect admission, approvals, or durable receipts. + +The model calls `codemode` with a `code` string containing the body of an async +JavaScript function. Independent reads can run in one wave; their results can +feed subsequent calls without another model request. Only `text()` output and +the returned value enter the model's tool-result context. + +```javascript +const matches = ALL_TOOLS.filter(tool => /search/.test(tool.name)); +text(matches.map(tool => ({name: tool.name, schema: tool.schema}))); +``` + +```javascript +const results = await Promise.allSettled([ + tools.read({path: "Cargo.toml"}), + tools.read({path: "README.md"}) +]); +text(results.map(result => result.status === "fulfilled" + ? {status: result.status, characters: result.value.length} + : {status: result.status, error: result.reason.message})); +``` + +Tool names and available arguments come from the admitted catalog, not from +script-supplied metadata. Names containing punctuation also have an identifier +alias, such as `tools.read_rows` for `read.rows`. Ambiguous aliases fail closed. +The catalog records the identifier on each entry. Dex exposes its ordinary +core or already-discovered tools; Maestro preserves its allowed-tool set and +profile restrictions. Conversational questions and confirmations use direct +tool calls. Recursive scripts are unavailable. + +Each script gets a fresh QuickJS VM embedded in the native binary. There is no +Node/Bun subprocess, host filesystem, network, module loader, process API, or +timer API. The host bridge emits tool requests; the composing agent applies +its normal authorization and execution path to each request. Permitted reads +run concurrently, while effects retain their existing ordered execution and +effect receipts. A script cannot authorize its own nested calls. + +The VM has a 32 MiB heap, a 256 KiB stack, a maximum of 64 nested calls, +64 KiB of output, and a hard 60-second deadline. Existing host deadlines and +cancellation may stop it sooner. Output-limit violations remain failures even +when the script catches the exception. A promise with no pending tool call +fails immediately. Unawaited requests are discarded when the script finishes. + +Failed tool calls reject their JavaScript promises. A script failure preserves +partial output; completed effects are not undone. Each composing agent retains +the underlying call evidence separately from the script's model-facing summary. +Restart handling preserves the existing refusal to replay an uncertain effect. + +The VM has no durable store. Script-local variables cover dependencies within +one call; existing agent journals remain the owners of execution state. This +change does not import Pi's provider transports, model-running helpers, or +session-storage format. + +The native engine is pinned to `rquickjs` 0.13.0, published September 8, 2026, +to retain the repository's fourteen-day dependency cooling period. Independent +archive review verified the three package checksums in both Cargo locks. +The exact `rquickjs-sys` build-script admission expires October 17, 2026. +With default features disabled, native builds compile the vendored QuickJS C +sources through `cc` and use bundled bindings.
