hcm_update_talent_profile

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

The readOnlyHint=false annotation already signals write behavior; the description adds that an approval workflow exists ('approval unless --write'), which is useful context beyond the annotations. However, the '--write' caveat is confusing because no such parameter appears in the input schema, leaving the agent unsure how to invoke the bypass.

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 concise with no filler and places the core action early. But it is so terse that 'Light' and '--write' introduce ambiguity, and the sentence does not provide enough operational clarity to be considered well-crafted.

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?

For a mutation tool with no output schema, sparse annotations, and an undocumented free-form body parameter, the description leaves critical gaps: the meaning of 'Light PATCH', the contents and constraints of body, the approval flow's effects, and the expected response. An agent cannot reliably call this tool correctly with the information given.

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%, so the description must explain both parameters. It does not describe profileId (format, where to find it) or body (required fields, allowed properties, patch semantics). The body is a free-form object with no sub-schema, and the description offers no compensation.

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 a specific verb ('PATCH') and resource ('talent person profile'), which clearly distinguishes it from worker, absence, and AOR update tools in the sibling list. However, the term 'Light' is unexplained, so the precise scope of the patch operation is ambiguous.

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 provided for when to use this tool versus alternatives, and no sibling tool is named (e.g., hcm_update_worker or hcm_get_talent_profile). The parenthetical 'approval unless --write' describes an operational behavior, not a usage condition, and gives no decision criteria for the agent.

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