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

The annotations already convey readOnlyHint and openWorldHint. The description adds that inputs are validated server-side and that the output is a structured, audited deliverable, which gives some useful context beyond the annotations. However, it does not disclose other behavioral traits like rate limits or how the open-world information is delimited.

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 contains fluff such as 'Gapup agent-payable C-suite expertise (SUSTAINABILITY)' and 'Reference case: Cas démo — Métriques diversité & inclusion', which do not help an agent select or invoke the tool. The useful parts (returns structured deliverable, server-side validation) are short but buried among irrelevant text.

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 a complex nested input schema, no output schema, and only 17% parameter documentation, the description is severely incomplete. It fails to explain what the deliverable contains, how inputs map to outputs, or how this tool relates to the many similar ESG/diversity tools in the sibling list.

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 only 17% (only 'async' has a description). The description says to 'send the documented case fields' without naming or explaining any of the parameters, thus adding no semantic value over the bare schema.

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 essentially restates the tool name in French ('Métriques diversité & inclusion') and promises a generic 'structured, audited deliverable'. It never specifies what the tool computes or how it differs from sibling tools like hr_benefits_esg_aligner, vendor_esg_diversity_scanner, or action_plan_esg.

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?

There is no guidance on when to use this tool vs alternatives. The 'Reference case' line simply gives a demo case name and does not explain appropriate contexts, prerequisites, or exclusions.

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