Remove Reaction from Message

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

Annotations provide idempotent and destructive hints. The description adds important context: it only removes the bot's reaction, not others'. Also describes return confirmation. No contradiction with annotations.

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 concise, well-structured with Args and Returns sections, and to the point. Every sentence adds value.

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 annotations and no output schema, the description covers purpose, parameters, and return value. Could mention emoji format or permissions, but overall complete enough for its complexity.

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 adequate parameter descriptions. The description repeats the parameter list without adding new meaning (e.g., emoji format not specified). Baseline score 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 clearly states the verb 'remove' and the resource 'the bot's emoji reaction from a message'. It distinguishes from siblings like discord_add_reaction (adds) and discord_delete_message (deletes message).

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?

No explicit guidance on when to use vs alternatives. The description implies it only removes the bot's own reactions, but does not mention prerequisites or exclusions. It is adequate for a simple tool but lacks proactive differentiation.

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