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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false and destructiveHint=false, so the safety profile is covered. The description adds nothing beyond that — no auth/permission requirements, no uniqueness behavior for target_url, and no reconciliation of the required idempotency_key against idempotentHint=false.

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?

A single short sentence with no filler, so it is not verbose. But the brevity is under-specification rather than economy — there is no second sentence earning its place by adding required detail.

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?

Seven parameters, two required, a nested body/query escape hatch, and no output schema; an agent needs to know what the response contains (the short URL) and whether reusing an idempotency_key returns the prior link. None of that is provided, so the definition is incomplete for a mutation 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 description coverage is only 57%, yet the description explains no parameters at all — nothing about target_url length/format constraints, brand_id, source_platform, or the body/query escape hatches. It therefore fails to compensate for the documented coverage 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?

Specific verb ('Create') plus resource ('short link') with a scope qualifier ('on the workspace'), so the agent knows this produces a link object rather than a post or report. However, it does not differentiate itself from the many link-creating siblings (create_connect_link, create_report_link, create_client_review_link), and 'manual' is undefined.

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 when-to-use guidance, no prerequisites, and no mention of alternatives despite several link-creation siblings. 'Manual' vaguely implies an automated counterpart exists, but the description never states the condition that selects this tool.

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