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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered; the description adds genuinely useful context that passwords are never returned, plus the endpoint 'GET /staffs'. It adds no detail on ordering defaults, page size behavior, or what an empty result looks like, so it remains modest beyond annotations.

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 with zero filler: purpose and returned fields first, the security caveat second, the endpoint last. Nothing is buried or redundant.

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 read-only list endpoint with full schema coverage and no output schema, the description covers purpose, returned fields, and a key data-sensitivity caveat. A note on pagination semantics (using next_page from the prior reply) would fully round it out, though the schema already carries that.

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 coverage is 100% and each of the four parameters (page, sort, limit, fields) carries a clear description including defaults and formats. The tool description adds no parameter semantics of its own, 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?

States a specific verb and resource ('List staff members') and enumerates the returned fields (id, code, name, role, e-mail), which lets an agent distinguish a bulk list from the singular smaregi_get_staff sibling. It stops short of naming that sibling explicitly, so the differentiation is inferred rather than stated.

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: 'List staff members' suggests a collection fetch and the pagination parameters hint at multi-page iteration, but there is no explicit guidance on when to prefer this over smaregi_get_staff for a single record. No exclusions or prerequisites are given.

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