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

The description discloses important behavioral details beyond annotations: effects and styles apply immediately, memories and notes are routed to the pocket, and flagged-identity kisses are held until the pocket is opened. This adds useful context to the annotations' simple non-read-only/destructive flags.

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?

Three sentences, front-loaded with the core action and followed by relevant effect and storage details. It is concise, though the pocket concept appears twice and could be slightly tightened.

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 two-parameter state-changing action with no output schema, the description covers the action's immediate effects, storage, and the special flagged-identity case. It does not define 'flagged identity' or failure conditions, but nothing essential for a correct call appears missing.

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 input schema already documents both room and kissId with 100% coverage, so the description is not required to add parameter details. It adds behavioral context about the kiss but no additional parameter-specific meaning, matching the baseline for complete schema coverage.

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 opens with a specific verb and resource: 'Accept a kiss offered to you.' It distinguishes itself from sibling tools like offer_kiss and decline_kiss by stating the accept action and its immediate effects.

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 phrase 'offered to you' implies this tool is for responding to an existing kiss offer, and the sibling decline_kiss provides the alternative. However, it does not explicitly say when not to use it or mention the alternative by name, so usage guidance is only implied.

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