capture_url

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

The description discloses background enrichment processing, which adds behavioral context. However, it does not mention idempotency, rate limits, authentication requirements, or whether the operation is synchronous, leaving gaps.

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 that is efficient and front-loaded with the core action. It avoids unnecessary words, though it could be slightly more structured.

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?

No output schema is provided, and the description does not explain return values or side effects. Background enrichment is mentioned but not elaborated (e.g., asynchronous behavior). Parameter descriptions are missing, making it incomplete.

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%, so the description must compensate. It only implies the 'url' parameter via the action 'Save a URL' but does not describe 'projectId' at all. This fails to add meaningful semantics for all parameters.

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 tool's purpose: 'Save a URL to Memlane' with a specific verb and resource. It also adds context about background enrichment (extract, embed, classify), distinguishing it from sibling tools like get_save or list_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 on when to use this tool versus alternatives. Sibling tools like add_topic_to_save or create_note exist, but the description does not explain scenarios for choosing capture_url over them.

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