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

Annotations already declare the safety profile (readOnlyHint=false, idempotentHint=false, destructiveHint=false), so the bar is lower. The description adds a real permission model not present in the annotations, which is useful, but it does not disclose partial-update semantics (are omitted fields left untouched, or cleared?) or what a null customPrompt does.

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 dense sentence that leads with the tool's scope and then appends the role constraints. Every clause carries information; nothing is redundant with the schema or annotations.

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 6 fully documented parameters, no output schema, and annotations covering the safety profile, the description is nearly complete. The remaining gap is partial-update behavior and how clearing guidance via null interacts with roles.

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 coverage is 100%, so the baseline is 3, but the description adds a per-field authorization mapping (name/guidance/interview independence vs. visibility vs. completion) that the schema does not express, giving the agent operational meaning beyond types and enums.

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?

Opens with a specific verb (Update) and resource (Clarity process) and enumerates the mutable fields: name, guidance, interview independence, visibility, completion status. This distinguishes it from nearby siblings like updateClarityProcessSharing, updateClarityProcessLabel, and updateClarityProcessLink, which it never names explicitly.

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 conditional guidance tied to each editable surface: Team Builders can edit names/guidance/interview independence, visibility requires creator or team manager, completion requires Lead Builder. It stops short of naming alternative tools for those concerns (e.g. updateClarityProcessSharing) or stating when not to use this tool.

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