update_qurl

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

No annotations provided, so description must cover behavior. It explains ID resolution and mutual exclusivity, but does not clarify if tags replace or append (though parameter schema says 'replace'). Missing potential side effects like overwriting description.

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?

Three sentences, front-loaded with purpose, no redundancy. Every sentence adds essential information.

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, so missing return value details. Covers key usage constraints but lacks error handling or examples. Adequate for an update tool but could be more complete.

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%, baseline 3. Description adds value by summarizing ID types and constraints, but most parameter details are already in the schema. No new semantics beyond what schema provides.

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 updates a qURL with specific actions: extend expiration, set expiry, update tags, or change description. It distinguishes itself from siblings like extend_qurl by covering multiple update types.

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?

Provides clear guidance on ID type acceptance (r_ or q_ prefix) and mutual exclusivity of extend_by and expires_at, plus requirement of at least one update field. Does not explicitly compare to sibling tools but implies its broader scope.

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