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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states 'Permanent action,' which hints at irreversibility, but lacks details on permissions required, rate limits, error conditions, or what the output schema might return. This is a significant gap for a destructive operation.

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 front-loaded with the core action and permanence warning, followed by a brief parameter explanation. Every sentence earns its place without redundancy, making it efficient and easy to scan.

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 tool's complexity as a destructive operation with no annotations, the description is somewhat complete but has gaps. It covers the purpose and parameter semantics adequately, and the presence of an output schema means return values don't need explanation. However, it lacks critical behavioral details like authentication needs or error handling.

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 includes an 'Args' section that explains 'tweet_id: ID of the tweet to delete,' adding meaning beyond the input schema, which has 0% description coverage and only lists 'Tweet Id' as the title. This compensates well for the low schema coverage, though it doesn't elaborate on format or validation.

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 specific action ('Delete one of your tweets') and identifies the resource ('tweet'), with 'Permanent action' emphasizing the nature of the operation. It distinguishes itself from sibling tools like x_like_tweet or x_post_tweet by focusing on deletion rather than creation or interaction.

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, such as whether it applies only to the user's own tweets or if there are prerequisites like authentication. It mentions 'your tweets' but doesn't clarify if this is exclusive or if other tools handle different deletion scenarios.

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