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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the safe read-only nature is covered. The description adds a behavioral detail about permission scoping (non-admin sees only own group), which is useful beyond annotations. No contradiction exists.

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 is two short sentences, front-loaded with the main purpose and a single key behavioral caveat. No wasted words, but it could be slightly longer to explain parameters or usage 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?

The tool is relatively simple (list departments) and annotations cover safety, but the description leaves out parameter details (e.g., pagination, name filtering) and does not specify output format. Given no output schema and 0% schema description coverage, more could be added about what the response contains (e.g., department IDs, names).

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 0%, so the description carries the burden for explaining parameters. However, it provides no detail about name, limit, or offset beyond what the schema's types reveal. For a list tool with pagination parameters, the description does not explain their semantics, but the parameter names are fairly self-explanatory, so a baseline of 3 is appropriate.

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 clearly states it lists organization departments, with a specific verb and resource. It also adds a scoping detail (non-admin attendants see only their own group's departments), which distinguishes it from generic list tools, though it does not explicitly contrast with sibling list tools.

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 implies when to use this tool (to list departments) but provides no explicit guidance on when not to use it or which alternative to choose. Sibling tools like tiflux_list_desks or tiflux_list_technical_groups are not mentioned, so an agent may not know the distinction.

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