get_user_tweets

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

The description says 'Get recent tweets' but does not disclose behavior such as rate limits, pagination, or handling of protected users. With no annotations provided, the description should provide more transparency.

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?

The description is extremely concise: three sentences with no filler. It front-loads the purpose and immediately follows with parameter explanations. Every sentence earns its place.

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?

Given the presence of an output schema, the description does not need to detail return values. It adequately covers the core functionality for a simple retrieval tool, though it could mention common fields like text or timestamp.

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?

The description explains both parameters beyond the schema: screen_name format ('without @') and count meaning ('Number of tweets to fetch') with its default value. Since schema has 0% description coverage, this adds significant value.

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 tool retrieves 'recent tweets from a specific user,' which identifies the specific verb and resource. It is distinct from siblings like get_tweet (single tweet) and get_timeline (home timeline), though it could explicitly differentiate.

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 provides no guidance on when to use this tool versus alternatives (e.g., get_tweet for a single tweet, search_tweets for keyword-based search). No exclusions or prerequisites are mentioned.

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