delete_tweet

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It correctly identifies the operation as destructive (deletion). However, it does not mention that deletion is irreversible, nor does it specify whether the action is idempotent, what happens if the tweet is already deleted, or whether the authenticated user's permissions are validated. For a destructive tool with no annotations, this is a moderate disclosure.

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 a single, concise sentence with no extraneous words. It front-loads the action and resource, immediately followed by the ownership constraint. Every word 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 that there is no output schema and the tool is destructive, the description could be slightly more complete. It does not mention the result of a successful deletion (e.g., returns a confirmation object or void), nor does it address error cases (e.g., not found, not owned). However, for a single-parameter, straightforward delete operation, the description is nearly adequate. A small increment in completeness, such as noting irreversibility, would push it higher.

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 a single 'tweet_id' parameter described generically. The description adds value by clarifying that the tweet must be owned by the authenticated user, which is a critical constraint not evident from the parameter description alone. This contextualizes the parameter meaningfully. No improvement needed.

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 action ('Delete'), the resource ('a tweet'), and the identifier mechanism ('by its ID'). The parenthetical constraint ('must be owned by the authenticated user') distinguishes this from generic deletion context, making the tool's purpose precise and unmistakable.

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 an implicit usage constraint: the tweet must be owned by the authenticated user. It does not explicitly state when not to use this tool or suggest alternative tools (e.g., use unlike or undo for non-deletion actions). However, the constraint is clear enough to guide the agent away from inappropriate calls.

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