add_to_shared_category

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

With no annotations provided, the description carries the full burden. It states the core action and constraint but does not disclose potential side effects (e.g., whether adding an already present bookmark causes an error), required permissions, or rate limits. Adequate for a simple operation but not fully transparent.

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 extremely concise with only two lines of narrative plus the Args list. It front-loads the purpose and constraint. Every word 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?

The description covers the basic operation and constraint but lacks information on success/failure indicators, error handling, or idempotency. Since there is no output schema, more context on the result or error conditions would improve completeness for a simple tool.

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 names are minimally described in the schema. The description adds that footprint_id is a bookmark ID and shared_category_id is a shared category ID, but doesn't explain how to obtain these IDs or any validation rules. Given 0% schema coverage, more detail would be expected; this is adequate but not excellent.

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 'Add' and the resource 'one of your existing bookmarks to a shared category'. It also specifies a key constraint: 'The bookmark must be yours'. This distinguishes it from sibling tools like create_shared_category or join_shared_category.

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 description provides a prerequisite ('The bookmark must be yours'), but does not explicitly explain when to use this tool versus alternatives or when not to use it. The context of sibling tools implies the usage, but explicit guidance would be beneficial.

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