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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the bar is lower. The description adds genuinely non-obvious behavior: expertise is descriptive only and confers no permissions, and the returned membershipId/revision are the inputs an administrator needs for a later update. That is useful context beyond the structured fields.

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?

Three short sentences, front-loaded with what is read, then the permission caveat, then the downstream usage hint. No filler and every sentence carries information.

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?

No output schema exists, and the description partially compensates by naming the key returned identifiers (membershipId, revision). It does not describe the overall shape of the member/function/expertise payload, but for a zero-parameter read tool the definition is largely sufficient.

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 and 100% schema coverage, so the baseline is 4. The description correctly documents the tool as taking no input while naming the values it returns (membershipId, revision) that other tools consume.

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: 'Read current Team/Enterprise members, business functions and expertise.' It is clear what the tool returns, but it does not differentiate itself from the very similar sibling helvabase_workspace_members, leaving the agent to guess which membership listing to call.

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 description clarifies the semantics of the data ('Expertise is descriptive and never grants workspace, dossier or review permissions') and points to a follow-up action ('Use returned membershipId and revision for an administrator update'), but it never states when to use this tool versus helvabase_workspace_members or helvabase_opportunity_profiles.

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