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

Annotations already provide readOnlyHint=false and destructiveHint=true, so the agent knows this is a mutating, destructive operation. The description adds only 'bounded', which is vague and not explained; it does not disclose side effects, permission requirements, reversibility, or the role of idempotency_key/archived_reason. This adds minimal behavioral context beyond the annotations.

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 short sentence, which is concise, but it is under-specified. It does not front-load critical information such as which fields are updatable or the meaning of 'bounded'. The sentence takes up space without earning its place, as it offers little actionable detail beyond what the title already says.

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 7 parameters, a destructive annotation, and no output schema, the description is severely incomplete. It does not explain how to use archived vs archived_reason, how idempotency_key should be used, what 'bounded' means, or any success/error behavior. An agent cannot confidently call this tool correctly based on the description alone, even with schema and annotations.

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 0%, and the description does not compensate by explaining any of the 7 parameters. The phrase 'bounded fields' gives no concrete information about name, archived, description, archived_reason, or idempotency_key. An agent is left to guess parameter semantics solely from names and JSON schema constraints, which is insufficient for correct invocation.

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 states the verb 'Update' and resource 'Talent CRM pool', so an agent knows it modifies an existing pool. However, the modifier 'bounded' is ambiguous and the description does not specify which fields are updatable, making it less clear than simply stating 'update a talent pool'. It does distinguish from create/list/read siblings by the action verb, but adds little detail.

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?

No guidance is given about when to use this tool versus alternatives like create/read/list. The description does not mention exclusions, prerequisites, or when a different tool would be more appropriate. The only implication is that it is for updating existing pools, which an agent could infer from the name and title, but this is not explicitly stated.

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