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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered elsewhere. The description contributes only the notion that exactly one record is returned for a given id; it says nothing about missing-id behavior, errors, or the shape of the returned organization.

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?

One front-loaded sentence with no filler or redundancy. It is appropriately sized for a one-parameter read tool, though it leaves room for a short clarifying clause about return or error behavior.

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 trivial single-param read with complete annotations and full schema coverage, the essentials are present. What is missing is low-cost but useful context: what to expect when the id does not exist and whether the result is a single object versus a wrapped response, given there is no output schema.

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 the single parameter already documents itself as 'The numeric id of the organization to fetch.' The description's 'numeric id' phrasing adds no format, range, or sourcing detail beyond that, so the schema does all the work.

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 ('Fetch'), a specific resource ('a single organization'), and the lookup key ('numeric id'). This clearly distinguishes it from create/delete/update-organization-tool siblings, though the description never names those alternatives itself.

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 on when to reach for this versus the other get-* tools or when an organization id is already in hand. The only implicit cue is 'single', which hints it is not a list operation, but nothing states preconditions or exclusions.

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