add_movie_by_id

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided. Description lacks details on behavior: what happens on duplicates, required permissions, side effects. Only mentions return is 'Result of the add operation'.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Short, uses clear Args/Returns structure, no wasted words. Could be slightly more concise but efficient overall.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Has output schema (not shown). Description covers basic purpose and parameters but lacks info on error handling, duplicate behavior, or validation. Adequate for simple operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage 0%, description adds minimal meaning: tmdb_id is 'The Movie Database ID', root_folder is 'Optional root folder path' with example. No extra constraints or format details.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the verb 'Add', resource 'movie', method 'using its TMDb ID'. Differentiates from siblings like add_show_by_tvdb_id which handles TV shows.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implied usage when you have a TMDb ID, but no explicit context on when not to use (e.g., if movie already exists) or comparison with siblings like search_movies.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
