get_bookmark

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

No annotations exist; description only states 'Get full details' without disclosing error behavior for non-existent IDs, authorization needs, or any side effects. Lacks essential behavioral context for safe use.

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, front-loaded sentence with zero wasted words, efficiently conveying the tool's core function.

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?

With an output schema present, return values need no elaboration. However, missing information about error handling (e.g., ID not found) prevents full 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?

Schema coverage is 100% with parameter description 'The bookmark ID'. Description adds no extra meaning beyond 'by ID', so it meets baseline but doesn't enhance understanding.

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 clearly states 'Get full details about a specific bookmark by ID', specifying verb, resource, scope, and method of identification, distinguishing it from sibling tools like delete_bookmark or get_bookmark_stats.

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?

Implies use when a bookmark ID is known and full details are needed, but no explicit guidance on when not to use or alternatives provided.

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