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

Annotations already declare this is a non-read-only, non-idempotent, non-destructive write. The description adds the accepted document types and that the capture is team-scoped, which is useful context, but omits URL expiry, permission requirements, and the fact that nothing is persisted until the upload is completed. Some added value against a lower annotation bar.

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 front-loaded sentence with no filler. The supported formats and scope are packed in without any redundant restatement of the name.

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?

For a 3-parameter tool with no output schema, the safety profile and parameters are covered by annotations and schema. What is missing is the multi-step contract — that the returned signed URL must be used to upload and then finalized via completeClarityTeamDocumentUpload — which an agent needs to complete the workflow correctly.

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 100%, so fileName, contentType, and team_id are already fully documented in the schema, including the API-key-vs-OAuth team pinning rule. The description adds nothing beyond what the schema provides, matching the baseline for high coverage.

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 a precise resource (signed URL for document upload) and a stated scope (team-level Clarity capture). The "team-level" qualifier implicitly separates it from createClarityDocumentUploadUrl and createClarityOrganizationDocumentUploadUrl, but those siblings are never named. Clear purpose, however the differentiation is left to inference via the name.

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?

The upload-URL phrasing implies a create-then-upload flow, but the description never states when to choose this over the other document-upload-URL siblings or that a follow-up call (completeClarityTeamDocumentUpload) is required. Usage is implied rather than guided.

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