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

Annotations already declare destructiveHint=true, so the description doesn't need to restate that. The description adds the 'soft-delete' action, which aligns with the destructive hint. However, it doesn't explain the implication of replacing the user list or whether the operation is partial or full replacement, though the schema covers 'Replace user list'.

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?

The description is a single, concise sentence that front-loads the action ('Update') and lists the updatable aspects. Zero wasted words, highly scannable.

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?

Given the schema provides full parameter descriptions and annotations indicate destructive behavior, the description is adequate for agent selection and invocation. It covers the core purpose and main fields, though it doesn't elaborate on return value or edge cases, which is not required here.

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 the schema fully documents all parameters. The description adds no additional meaning beyond mapping the parameters to fields (title, users, soft-delete), which is already in the schema. Baseline 3 is appropriate.

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?

The description clearly states 'Update a department' with specific updatable fields (title, users, soft-delete), using a specific verb and resource. It distinguishes itself from sibling tools like create_department, get_department, and list_departments.

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 implies usage: use this when you need to modify an existing department's title, users, or soft-delete status. It does not explicitly name alternatives or exclusions, but the context is clear given the verb 'update' and the listed fields.

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