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

Annotations already indicate readOnlyHint=true, idempotentHint=true, destructiveHint=false, covering the behavioral profile. The description adds that it returns Watchmode title IDs, which is useful but not extensive. No behavioral traits beyond annotations are disclosed.

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?

Two sentences, no redundancy. Purpose and optional parameters are front-loaded. Every sentence adds value.

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?

The tool has an output schema (not shown), so return values need not be described. The description covers input parameters and purpose. However, it omits details like pagination, multiplicity of results, or ordering, but annotations (openWorldHint) and output schema may compensate.

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 description coverage is 0%, so the description must compensate. It explains that search_value can be a name or ID (with search_field indicating type), and types is optional. However, it does not list allowed values for search_field (e.g., 'title', 'imdb_id', 'tmdb_id') or types, leaving some ambiguity.

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?

The description clearly states the verb 'Search', the resource 'Watchmode titles', and the scope (by name or ID, with optional type filter). It distinguishes from sibling tools like 'list_titles' which likely retrieves all titles without search.

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?

The description explains when to use the tool (searching by name/ID, optionally filtering by type), but does not explicitly exclude cases or mention alternatives. However, the context is clear enough for guided use.

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