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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that the full configuration (not a partial view) is returned, but says nothing about permissions, scoping, or response shape beyond the schema.

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?

A single front-loaded sentence with no filler and no restated boilerplate. It is arguably underspecified rather than padded, so it loses a point only for being too thin to carry usage or behavioral context.

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?

No output schema exists, yet the description does not characterize what the returned configuration contains or whether it is paginated/truncated. For a simple two-parameter read tool with full annotation and schema coverage this is minimally adequate, but it leaves the agent to discover the payload shape by calling it.

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%: site is explained as a site id from list_sites that overrides the connection default, and desk_id as coming from list_desks. The description adds no parameter meaning beyond the schema, so the baseline 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?

Specific verb ("Reads") plus resource ("one desk's full configuration"), so the agent can tell it retrieves a single desk object rather than a list. It does not, however, distinguish itself from sibling get_desk_embed, which an agent must infer from the name alone.

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?

Usage is only implied: a single-desk read obviously follows list_desks, and the schema's desk_id description names list_desks as the source. There is no explicit when-to-use / when-not-to-use statement, and no mention of get_desk_embed as the alternative for embed scenarios.

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