Create a release short URL

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

Description adds 'or return the existing' beyond the idempotentHint annotation, clarifying idempotent behavior. No contradictions with annotations.

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 sentence with no wasted words, front-loading the essential action and idempotency.

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?

Covers core purpose and idempotency, but lacks details on return value format, error conditions, or authentication requirements. Adequate 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?

The only parameter 'release_id' is self-explanatory from context, but the description does not explicitly explain it. With 0% schema coverage, some description would help, but the simplicity mitigates the gap.

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 'Create (or return the existing)' and resource 'short URL' for a release's smart-link landing page, distinguishing it from sibling tools.

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?

'Safe to repeat' indicates idempotency, and the tool is unique among siblings, so usage context is clear. No explicit when-not or alternatives, but not needed.

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