get_tweet_by_id

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

With no annotations provided, the description must convey behavioral traits. 'Fetch' implies a read operation, but it does not disclose rate limits, authentication needs, error handling for non-existent tweets, or any side effects. The description is too brief to give full 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 only 6 words, highly concise. It is front-loaded with the key action and resource. However, it could be slightly improved by structuring with additional context without becoming wordy.

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 simple tool with one parameter and no output schema, the description is minimally adequate. It states the basic purpose but omits details about return format, error conditions, or any special behavior. There is room for improvement.

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 100% with the 'id' parameter described as 'Tweet ID'. The description does not add any further meaning beyond what the schema already provides. Baseline 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 uses 'Fetch a specific tweet by ID' which clearly specifies the verb (fetch) and resource (tweet by ID). It distinguishes this tool from siblings like search_tweets or get_user_tweets that operate on multiple tweets or by different criteria.

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 does not provide any guidance on when to use this tool versus alternatives. It only implies usage when a specific tweet ID is known, but lacks explicit when-not conditions or comparisons to sibling tools like search_tweets.

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