search_bookmarks

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

Description is consistent with readOnlyHint and openWorldHint annotations but adds no extra behaviors (e.g., pagination, rate limits, or whether search is full-text).

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?

Single sentence is too brief; lacks structure and important details. Missing information would have been valuable without being verbose.

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?

For a search tool with two parameters and no output schema, description fails to explain search behavior (e.g., what fields are searched), pagination via cursor, or result format.

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 is 50% (only 'q' described). Description does not mention parameters or add meaning beyond schema. 'cursor' parameter is undocumented.

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?

Clearly states verb 'search' and resource 'user's Twitter bookmarks'. This distinguishes it from sibling tools like 'list_bookmarks' (which lists all bookmarks without query) and 'advanced_search_tweets' (which searches tweets generally).

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?

No guidance on when to use this tool versus alternatives. Does not mention required authentication or context for searching bookmarks.

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