bookmark_circular

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

No annotations are provided, so the description carries the burden. It accurately describes the action (bookmarking) and optional note addition, but does not clarify side effects, permissions, or reversibility. For a simple mutation, it is adequate but not rich.

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?

Two sentences, no unnecessary words. The core purpose and optional notes are front-loaded, making it easy to scan.

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?

For a simple bookmarking tool with 2 parameters and no output schema, the description is complete. It explains the action, the target resource, and the optional notes, covering all key aspects.

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 100% (both parameters described). The description adds useful examples (e.g., '150/5200-28F' for ac_number and 'need to review...' for notes), providing meaning beyond 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 verb 'Bookmark' and the resource 'FAA Advisory Circular', placing it in the context of an airport's tracking list. This distinguishes it from sibling tools like remove_bookmark or 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?

The description implies when to use (to track a circular) but does not explicitly state prerequisites or contrast with alternatives. Sibling tools are present, but no guidance on when not to use this tool or when to use another is provided.

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