Remove merge request reaction

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

Annotations already indicate destructiveHint=true and readOnlyHint=false, so the mutating nature is known. The description adds no additional behavioral context, such as irreversibility, permission requirements, or any side effects beyond what the annotations state. No contradiction, but it fails to provide extra transparency beyond structured data.

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 that states the action, target, and method. No verbose or redundant information; every word contributes to understanding.

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 delete operation with an output schema present and mutating annotations, the description is adequate. It doesn't discuss return values or error conditions, but the low complexity and existing structured annotations make it sufficiently complete for an agent to invoke correctly.

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 schema has 50% description coverage, so the description should compensate for missing parameter meaning. It references 'award ID' and distinguishes 'merge request or note', adding some semantics for award_id and note_id. However, it does not explain project or merge_request_iid beyond what schema provides, though these are self-explanatory.

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 ('Remove an emoji reaction') and the resource ('from a GitLab merge request or note') and specifies the key parameter (by award ID). It is specific and distinct from sibling tools like add_merge_request_reaction or list_merge_request_reactions.

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 implies usage for removing a specific reaction but does not explicitly mention alternatives, prerequisites (e.g., knowing the award ID from a list), or when this should be used over other reaction tools. There is no when-not guidance, but the purpose is clear enough.

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