Codex review of the vocabulary relocation found two doc-accuracy issues:
- presentation.ts's JSDoc used {@link ToolDefinition...}, which the
TypeScript language service cannot resolve because presentation.ts
deliberately does not import index.ts (that would create the cycle the
split avoids). Demote those three to plain `ToolDefinition` code text;
same-file and imported @links (TerminalResultView, ContentBlock) stay.
- docs/core-data-structures/tools.md's source header listed only index.ts
and schema.ts; add presentation.ts, which now owns the presentation
vocabulary the page documents.
The tool render-intent vocabulary (ToolCallView/ToolResultView + members,
FileLocation, FileDiff, ToolCallKind) is the UI-facing surface of
dsh-tools; it lived inline in index.ts alongside the registry and
execution core. Move it to its own presentation.ts module so index.ts is
the registry + execute waterfall and the presentation vocabulary is a
separate, one-directional dependency.
presentation.ts owns ONLY render-intent types and references none of the
execution types; index.ts imports the view types for ToolDefinition's
presentCall/presentResult signatures (clean acyclic index -> presentation).
The opaque `meta` presentation channel (ToolExecuteReturn, ToolResult,
ToolExecutionResult) is execution plumbing and stays in index.ts.
Public surface unchanged: index.ts re-exports the vocabulary, so consumers
(tool-fs/tool-bash/tool-web/tool-todo, the ACP bridge) keep importing from
@deepseek-ai/dsh-tools with zero churn. No producer/bridge/test edits; a
pure internal relocation with no observable-output change (snapshot goldens
untouched).
