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

The annotations already declare readOnlyHint=true, so the safe-read profile is covered. The description adds the field set returned and the underlying endpoint, but says nothing about pagination behavior, default page size, or limits beyond what the schema states. Added value is modest given annotation coverage.

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?

Two compact, front-loaded sentences with no filler; the resource and returned fields come first. The trailing endpoint reference is slightly redundant for an agent but is cheap and potentially useful for API-aware callers.

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 two-param paginated list with a readOnly annotation and no output schema, the description compensates by naming the returned fields. The main gap is the absence of pagination context (how to page through results), which is left entirely to the schema.

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%, with both page and per_page fully documented (defaults, maximums). The description adds no parameter detail beyond the schema, so baseline 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?

States a specific verb and resource ('List the clients') and clarifies what a client is ('people or companies proposals are prepared for'), which an agent could otherwise confuse with proposals. It enumerates returned fields (id, name, email, phone), making the shape concrete. Sibling differentiation from get_client/list_client_proposals is implied by 'list' but not made explicit.

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 the list-vs-get naming pattern shared with siblings like bidsketch_get_client and bidsketch_list_client_proposals. There is no explicit statement of when to prefer this over get_client or list_client_proposals, and no exclusions noted.

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