add_to_wantlist

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

Lacks annotations; description only states the basic action. No details on whether the tool overwrites duplicates, rating semantics, or side effects. Adequate but minimal.

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?

Single sentence is efficient but overly sparse, missing essential details for a write operation. Conciseness comes at the expense of completeness.

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?

No output schema, no behavioral traits disclosed, no error handling info. For a tool with 4 parameters and a write operation, the description is insufficient.

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 0% and description does not explain any parameters, including the meaning of rating or notes. Self-explanatory names like username and release_id only partially compensate.

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?

Description uses verb 'Add' and resource 'release to wantlist', clearly indicating the tool's primary action. It distinguishes from siblings like edit_item_in_wantlist or delete_item_in_wantlist.

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 on when to use this tool versus alternatives like edit_item_in_wantlist for existing entries. No context on prerequisites or scenarios.

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