Firm users

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

With no annotations, the description carries the burden, and it does disclose the returned fields. However it says nothing about permissions, pagination, or whether disabled users are included, and the safety profile (read-only listing) is only implied by the verb 'Lists'.

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; resource, returned fields, and intended uses all appear before any elaboration. Nothing could be trimmed without losing information.

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 simple list endpoint with no output schema and no annotations, disclosing returned fields plus use cases covers most of what an agent needs. The remaining gap is scope ambiguity (enabled vs. all users) and any permission requirements.

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 0% for the single optional boolean 'enabled_only', and the description never explains it or the default scope of the list. The parameter name is largely self-explanatory, so the gap is modest rather than severe, but the description adds no meaning here.

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?

Names a specific verb and resource (lists Clio users) and enumerates the fields returned (id, name, e-mail, roles, rate), so the agent knows exactly what comes back. No sibling tool provides user data, so it is unambiguous within this tool set.

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?

Gives concrete use cases: assigning tasks and matters, and recording time on behalf of another user. That tells the agent when this tool is the right lookup, though it names no alternative or exclusion condition.

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