# @deepseek-ai/dsh-tool-cordis

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](../../../docs/rfc/implemented/feature/2026-07-08-self-referential-cordis-toolset.md).

## 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](../../../docs/tool-catalog.md).

## 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](../../../docs/cordis-catalog/services.md) 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](../../../docs/postmortem/0001-acp-default-export-drops-inject.md)).
