  *
- * Both the webapp's `DEFAULT_AI_POLICY` and the server-side

  * Adding a new proposable tool:
- *
- *   1. Append its name to {@link AI_PROPOSABLE_TOOL_NAMES}
- *   2. Add the tool with its params to `AI_AVAILABLE_TOOLS` in mana-ai
- *      (the contract test below ensures step 2 isn't forgotten)
- *   3. The webapp's `DEFAULT_AI_POLICY` picks it up automatically
- *
- * Tools NOT in this list default to `'propose'` only if the per-tool
- * policy map lacks an explicit entry. Most `auto` / `deny` decisions
- * stay hardcoded in the webapp policy — this shared list only covers
- * the tools the *server-side* planner actively proposes.
+ *   1. Add its schema to `AI_TOOL_CATALOG` with `defaultPolicy: 'propose'`

 /**
- * Hardcoded allow-list of tools the server-side Planner may propose.
+ * Server-side tool list — derived from the AI Tool Catalog.
  *
- * Parameter shapes live here (the webapp owns the full Dexie-bound
- * registry); the set of NAMES is shared via `@mana/shared-ai`'s
- * `AI_PROPOSABLE_TOOL_NAMES`. The module-load assertion at the bottom
- * guards against drift in either direction — if this file or the shared
- * list falls out of sync, the service refuses to start.
+ * The full schema definitions now live in `@mana/shared-ai/src/tools/schemas.ts`.
+ * This file filters the catalog to the proposable subset (tools the server-side
+ * planner may suggest) and provides the name sets used by the parser and drift guard.
+ *
+ * Adding a new tool: add it to `AI_TOOL_CATALOG` in `@mana/shared-ai` — this
+ * file picks it up automatically.
