Unlike Post

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

Annotations already indicate that the tool is destructive and idempotent. The description adds the behavioral context that the action is performed 'on behalf of the authenticated user', which is not captured by the annotations and clarifies whose like is removed.

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 redundant words. It front-loads the action and includes all necessary context without being verbose.

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?

This is a simple one-parameter mutation with no output schema. The description covers the purpose, the scope (authenticated user), and how the post is identified. Error conditions are not described, but they are not essential for a tool with this level of simplicity.

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 clear description of the tweet_id parameter. The description's 'by its ID' simply aligns with the schema without adding new meaning, so the baseline 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 uses a specific verb 'Remove' and identifies the exact resource ('a like from a post') and the actor ('on behalf of the authenticated user'). This clearly distinguishes it from sibling tools like x_like_post, which adds a like.

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 clear context: it removes a like for the authenticated user, which implies when to use it. However, it does not explicitly mention alternatives or exclusions, such as 'for adding a like use x_like_post', so it doesn't reach the highest level.

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