### Problem/Motivation Three globally-namespaced identifiers are unprefixed. Identifier renames after RC1 break other modules, so this is a freeze item. 1. **Alter hook**: `TypedDataAdapterManager` (src/TypedData/Adapter/TypedDataAdapterManager.php:24) calls `$this->alterInfo('data_type_adapter_info')`, creating `hook_data_type_adapter_info_alter()`. Drupal convention requires module-prefixed alter hooks; a collision with another module implementing a generic "data type adapter" concept is plausible. 2. **Cache key**: same class, `setCacheBackend($cache_backend, 'data_type_adapter_plugins')` — unprefixed cache collection. 3. **DataType plugin ID `text`** (src/Plugin/DataType/TextData.php:14): registers the id `"text"` in the global typed-data plugin space. The `typed_data` contrib module also defines `text`; installing both produces nondeterministic plugin definitions. ### Proposed resolution - `alterInfo('tool_typed_data_adapter_info')` → `hook_tool_typed_data_adapter_info_alter()`. - Cache key `tool_typed_data_adapter_plugins`. - DataType id `tool_text` (update `src/TypedData/Type/TextInterface.php` usages, the `TextAdapter`, and any input definitions using `text`). Alternatively depend on/coordinate with the typed_data module — but a prefixed ID is the self-contained fix. - Document the alter hook in `tool.api.php` (see the annotation-sweep issue). Grep-verify no other unprefixed identifiers ship (queue names, tempstore collections — `tool_handles` is already fine). ### API changes Hook name, cache key, and data type ID rename. Pre-RC1 this affects no released API; post-RC1 it would be a BC break for adapter implementers. ### AI usage (if applicable) - [x] **AI Assisted Issue:** This issue was generated with AI assistance, but was reviewed and refined by the creator. - [x] **AI Assisted Code:** This code was mainly generated by a human, with AI autocompleting or parts AI generated, but under full human supervision. - [x] **AI Generated Code:** This code was mainly generated by an AI with human guidance, and reviewed, tested, and refined by a human. - [ ] **Vibe Coded:** This code was generated by an AI and has only been functionally tested.
