Scored across 9 tools
Each tool has a distinct purpose: job management tools (cancel, error, result, status, list) are clearly separated from action starting tools (import, export, edit tracking) and server configuration. No overlap.
All tool names follow a consistent verb_noun pattern in snake_case. Prefixed verbs like cancel_, list_, start_ and noun prefixes like job_, server_ maintain predictability.
Nine tools is appropriate for a Lightroom Classic server. It covers job management and core operations without being too few or overly numerous.
The tool set covers job lifecycle (create, monitor, cancel, get results) and main operations (import, export, edit). Missing a delete job tool but the core workflow is fully supported.
