imccyu ec601ca13d build(vendor): rescope the vendored Cordis packages into @deepseek-ai
Machine-produced by `pnpm run rescope-vendor --apply` plus the regeneration it
prints: `pnpm install` for the lockfile, `pnpm run gen-third-party-notices`,
`verify-translation-pairing --write` for the touched bilingual pairs,
`gen-doc-graphs`, and one typert snapshot whose ids embed character offsets.
`pnpm run rescope-vendor --check` verifies the result.

Renames nine vendored packages (cordis, cosmokit, schemastery and the six
@cordisjs plugins) and every reference that resolves them: manifest names and
dependency keys, module specifiers including declare-module merges, cordis.yml
plugin names, tsconfig paths, every Markdown fence, and `docs/` prose.
Directory names, upstream versions, and dependency ranges are unchanged, so
vendor/README.md still reads as an upstream snapshot; its manifest table gains
an upstream-name column so THIRD_PARTY_NOTICES keeps MIT attribution pointed
at each fork's origin.

The tutorial tier follows the rename end to end: its yaml fences named plugins
the Loader can no longer resolve, its `ts ignore-check` fences disagreed with
the compiled fences beside them, and its prose quoted both. The contracts that
told readers to keep upstream names — the root convention and the vendoring
cookbook's tree comment and manifest invariant — now say to rescope instead.

Two rules read `@deepseek-ai/` as "another workspace plugin": the client bundle
purity gate now names the vendored libraries a browser bundle inlines, and the
files where a bare `cordis` is an agent-preset id keep that product data.

dsh-agent-tool-mode

English | 中文

The row an agent preset carries to say which form of its tools the model sees: native (every schema), code (only run_code plus a generated TypeScript SDK), or both.

Why a row rather than a registry

The tool registry cannot move into a preset. Its consumers are all host-plane — dsh-agent-loop reads its scheduler, dsh-apiproxy reads its presenters to render tool cards, and every tool plugin registers into it — and a service only moves down when all of its consumers move with it.

What a preset can own is the presentation of that registry. ctx.tools.presentAs() declares it for the mounting agent alone, so a Code Mode session runs beside native ones in one process, each seeing its own catalog. The deployment's mode on the dsh-tools row remains the default that agents declaring nothing get.

What it does

native applies immediately. A code mode instead waits for ctx.codeRuntime, which is a host-plane service (dsh-code-runtime-worker): a preset selecting Code Mode against a deployment composing no runtime then holds this row pending, and dsh-agent-presets refuses the mount naming this id. The alternative — applying optimistically — moves the failure to the session's first request, where the operator can act on neither the preset nor the composition.

mode is required rather than defaulted, because a preset without this row already gets the deployment default; an omitted value would mean the row was composed for nothing.

One agent declares one presentation. A second declaration in the same composition is refused rather than merged: two answers to "which form does the model see" is a contradiction, not an override.

Model Experience

Indirectly, through the projection it selects in dsh-tools: code presents run_code plus a generated SDK section, native presents every tool schema.

KV Cache effect

No direct invalidation; the presentation is fixed when the agent is composed, so its request prefix is stable for the session's life.

Known Limitations and Deferred Work

  • The runtime stays host-plane — a preset can select Code Mode but cannot supply the TypeScript runtime it needs; a deployment that composes none can compose no code-mode preset.
