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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds only the HTTP endpoint (GET /api/organization.json) and the shape of what is returned; it says nothing about auth requirements, rate limits, or response nesting.

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?

Two short sentences with the core action front-loaded and no padding. The trailing endpoint path is marginally redundant but harmless.

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 simple read-only tool with zero required parameters, full annotation coverage and a fully documented schema, the description tells the agent what is returned (org name, optionally departments and agents). With no output schema, it does not detail the response structure, which is a minor gap.

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% and both booleans are self-documented ('Include the agents (users)', 'Include the departments'). The description merely restates their effect, adding no syntax or default-value detail beyond the schema, so the baseline of 3 applies.

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?

States a specific verb and resource ('Retrieve the organization (account) name') plus the optional expansion into departments and agents, which is more precise than the tautological title. It does not explicitly differentiate itself from siblings such as list_departments or list_agents, leaving the agent to infer that this is the org-level roll-up.

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 phrase 'optionally with its departments and agents' implies when the include flags are useful, but there is no explicit when-to-use guidance or routing to alternatives like list_departments/list_agents for those collections separately.

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