Api ebios rm stakeholders chart data retrieve

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered. The description adds no behavioral context of its own: no indication of what data shape is returned, whether it is scoped to a study, or whether it is cached/derived. It is not contradictory, just empty.

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?

It is extremely short, but shortness here reflects under-specification rather than efficient structure. The single token is an identifier, not a front-loaded statement of purpose, so it wastes the one line it occupies.

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?

There is no output schema, no parameters, and no description of the returned chart data, so an agent has no way to know what calling this produces (chart labels/values, per-stakeholder groupings, required prior selection context). For a chart-data endpoint in a large sibling set, the definition is completely inadequate.

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?

The tool takes zero parameters and the schema is an empty object with additionalProperties=false, so there is nothing for the description to explain. The baseline of 4 applies since no parameter semantics are needed.

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 is the raw operation identifier repeated verbatim ('api_ebios_rm_stakeholders_chart_data_retrieve'), which only restates the name. An agent can piece together that it retrieves chart data for EBIOS RM stakeholders, but nothing states what the chart represents or how it differs from siblings like stakeholders_list or studies_ecosystem_chart_data_retrieve.

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 contains no usage guidance whatsoever: no when-to-use, no when-not-to-use, no prerequisites, and no reference to any of the numerous sibling tools such as stakeholders_list or stakeholders_category_retrieve. The agent is left to infer selection purely from the identifier.

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