The self-referential cordis toolset: three model-facing tools over the live runtime the agent runs inside. Design home — sandbox semantics, mount lifecycle, cross-mount composition, the generated API catalog, standing decisions: the toolset RFC.

What it does

cordis_inspect — read-only report over the runtime: services, the loaded-plugin list, registered tools, the dynamic-mount table, and the catalog-backed api / events references.
cordis_mount — evaluates model-written JavaScript (the body of an async function) in a node:vm sandbox; the code must return a cordis plugin, which is mounted under the cordis-dynamic group fiber and tracked as dyn-<n>.
cordis_unmount — disposes one mount by id, returning only after quiescence.

Exact model-facing schemas: the generated tool catalog.

Trust stance

The sandbox isolates globals but is not a security boundary. Node globals are absent or redirect to Cordis services, and writes to globalThis stay local, but host-realm helpers and the privileged context make escape possible. Mounted plugins receive a façade without framework internals, yet its allowed services affect the live runtime. Treat this toolset like bash access.

Config

Field	Default	Meaning
`vmTimeoutMs`	`5000`	Bound on the SYNCHRONOUS portion of mount-code evaluation; an async body escapes it

The generated API catalog

src/api-catalog.ts is generated by scripts/gen-cordis-api.ts from the same AST walk as docs/cordis-catalog and freshness-gated by pnpm run verify-cordis-api (in doc-sync) — never edit it by hand. cordis_inspect intersects it with the live service store at call time.

Rendering

All three tools render generic cards (read / execute / delete); cordis_mount carries the mount code as rawInput. Presenters are pure functions of the args; results keep the default text rendering.

Export shape

Namespace plugin: named exports name / inject / Config / apply, no default export (docs/postmortem/0001).
