reorder_bookmarks

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

The description implies a mutation but does not disclose potential side effects, authorization requirements, or error conditions. No annotations are present to supplement behavioral context.

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, efficient and front-loaded, but it lacks detail needed for a tool with a nested input schema. It is concise but does not fully earn its place given the missing information.

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 absence of annotations, no output schema, and a complex nested input, the description barely covers the purpose. It does not explain outcomes, constraints, or the scope (current user) beyond a brief mention.

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 description coverage is 0%, and the description only mentions 'providing the new ordering' without explaining the structure of the 'input' parameter or the 'orderings' array. The agent would have to infer all parameter details from the schema alone.

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 ('reorder') and resource ('bookmarks') for the current user. It distinguishes from siblings like create_bookmark, delete_bookmark, and list_bookmarks.

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, such as create_bookmark or list_bookmarks. There is no mention of prerequisites (e.g., existing bookmarks) or scenarios where reordering is appropriate.

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