Mark game on hold

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

Without annotations, the description must explain behavior. It only says 'mark as on hold' without detailing side effects, idempotency, or what happens if the entry is already on hold. The tool's behavioral implications are unclear.

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 sentence with no extraneous words, but it is too brief and omits essential information. It sacrifices completeness for conciseness.

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 the tool's simplicity (one parameter, no output schema), the description is incomplete. It fails to explain return values, error conditions, or the meaning of 'latest', leaving gaps for safe usage.

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 parameter 'metadataId' is not explained in the description, despite 0% schema coverage. The agent may not know what value to provide, as the context of 'metadataId' is not clarified.

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: 'Mark the latest game progress entry as on hold.' It uses a specific verb and resource, differentiating it from sibling tools like 'ryot_mark_game_completed'. However, the term 'latest' is ambiguous and could be clarified.

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 guidance is provided on when to use this tool versus alternatives like 'ryot_mark_game_started' or 'ryot_mark_game_dropped'. The usage context is implied but not explicitly stated.

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