edit_short_url

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

Annotations already communicate readOnlyHint=false, idempotentHint=true, and destructiveHint=false. The description adds no behavioral context such as whether only provided fields are updated, permission requirements, or side effects beyond the operation itself.

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 lean sentence with no fluff, thus it is concise and scannable. However, it is under-specified for the tool's complexity, but that is more a completeness issue than a conciseness one.

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?

Given 11 parameters, no output schema, and minimal annotations, this description is severely inadequate. It provides no information about return values, parameter semantics, default behaviors, or update semantics, making it impossible for an agent to correctly invoke the tool without external knowledge.

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 only 9% (only shortCode has a description). The tool description adds no explanation for any of the 11 parameters, leaving ambiguous fields like crawlable, forwardQuery, and validSince/Until without semantic context.

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 uses the specific verb 'Edit' and the resource 'existing Shlink short URL', making the action and object clear. It distinguishes itself from sibling tools like create_short_url, delete_short_url, and get_short_url.

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 is provided on when to use this tool versus alternatives. The word 'existing' implies it's not for new URLs, but there is no explicit mention of prerequisites, when-not-to-use, or pointing to create_short_url for new entries.

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