get_user_tweets

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

No annotations provided, but the description only says 'Fetch tweets'. It does not disclose rate limits, pagination behavior, sorting order, or whether the tool respects privacy settings. Adds minimal behavioral context beyond the name.

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 with no excess words. Perfectly concise.

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?

No output schema, and description lacks details on return format, error handling, or limitations (e.g., max tweets beyond count). For a tool with 4 params and moderate complexity, more context is needed.

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?

Input schema covers 100% of parameters with descriptions. The tool description adds no extra info beyond the schema, so a baseline score of 3 is appropriate.

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 'Fetch tweets from a specific user', which is a specific verb-resource pair. It disambiguates from sibling tools like search_tweets (keyword search) and get_tweet_by_id (single tweet).

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 explicit guidance on when to use this tool versus alternatives. The description implies fetching all tweets of a user, but does not mention exclusions or when to prefer follow_user, get_followers, etc.

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