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

Annotations already cover the safety profile (readOnlyHint=true, destructiveHint=false, openWorldHint=false), and the description adds genuine context beyond them: the id space is bounded to this workspace and ids from elsewhere are rejected on write. It does not describe ordering or pagination behavior, but the added scoping caveat is real value.

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?

Three short sentences, front-loaded with what the tool returns, then the read-only guarantee, then the id-contract caveat. No filler or redundancy.

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?

With no output schema, the description should say what a member record contains beyond the id, and with undocumented pagination params it should explain result set size and paging. It covers the id contract well but leaves the return shape and paging semantics unstated for a tool whose only job is to return a list.

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?

Both parameters (limit, offset) have zero schema description coverage, so the description carries the full burden of explaining them — and it says nothing about paging, defaults, or the 1-100 limit. The only semantic content concerns the returned id, not the inputs.

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 gives a specific verb and resource ('List the workspace's members') plus a clarifying gloss that these are the people an HR record can be assigned to. It stops short of differentiating itself from the very similar sibling hr_list_people, so an agent must still guess which listing to call.

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: by explaining that the returned 'id' is the 'responsible_user_id' that people, vacancies and applications accept, it hints that this tool exists to source ids for write calls. There is no explicit when-to-use/when-not guidance and no pointer to the sibling that lists actual person records.

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