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

Annotations already declare readOnlyHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that the response is scoped to the authenticated caller, but says nothing about auth failure behavior or whether fields can be null.

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?

Two sentences, front-loaded with the return contract, then the usage guidance. No filler, and each clause carries distinct information an agent needs.

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?

With no output schema, the description's explicit field enumeration does the heavy lifting for an agent that needs to know what comes back. Only gap is edge cases (unauthenticated call, missing organization), which is minor for a trivial no-arg read.

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?

Zero parameters, so the baseline is 4. The description's field list is about return values rather than inputs, but it usefully signals that the call implicitly targets the current user, complementing the empty schema.

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?

States a specific verb and resource ('Returns the authenticated user's ShortSync profile') and enumerates the returned fields (user_id, email, current_organization_id, creation date), which distinguishes it clearly from siblings like list_organizations or list_workspace_people.

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?

Gives three concrete use cases: introducing yourself, confirming which account is connected, and resolving the default organization before calling other tools. This is actionable routing guidance, though it names no explicit alternative or exclusion condition.

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