save_bookmark

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

No annotations are provided, so the description must disclose behavioral traits. It only says 'Save a bookmark' but doesn't mention persistence, overwriting behavior, idempotency, or any side effects. The 'vector store' hint is vague and lacks depth.

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, efficient sentence with no redundant wording. It gets straight to the point, though it is extremely brief for a tool with three required parameters.

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 is minimal and fails to provide context about return values, error cases, duplicate handling, or the relationship with search_bookmark. Given the lack of annotations and output schema, this is a significant gap.

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 has three parameters (name, link, additional_detail) with no descriptions, and schema_description_coverage is 0%. The description doesn't explain the meaning, format, or purpose of any parameter, leaving the agent to guess.

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 ('save'), the resource ('bookmark'), and the destination ('vector store'), distinguishing it from the sibling tool 'search_bookmark' which searches rather than saves.

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 given on when to use this tool versus the sibling 'search_bookmark'. It doesn't mention any prerequisites, typical use cases, or situations where saving is appropriate.

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