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

Annotations carry idempotentHint=true and destructiveHint=false, and the description adds no behavioral detail beyond those. Notably readOnlyHint=false is left unexplained: the 'Read' phrasing gives no hint about possible side effects, what the readiness computation involves, or what state changes may occur.

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?

Five words with zero filler; the action and resource are front-loaded. Every word earns its place, though the brevity comes at the cost of semantic richness elsewhere.

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 explain what the readiness result means or how to respond to it, but it says nothing about return semantics, readiness conditions, or follow-up actions. For a simple 2-param tool the complexity is low, but the missing meaning of the result is a significant gap.

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%, yet the description adds nothing about either parameter. interview_session_id is inferable from the tool name, but request_id's purpose is entirely opaque, and the description fails to compensate for the schema's lack of documentation.

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 names a specific verb ('Read') and resource ('interview-session scheduling readiness'), and the readiness concept distinguishes it from sibling session tools like cancel, complete, start, and read. However, 'readiness' is never defined, so an agent understands the general area but not the precise meaning of the result.

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?

No explicit guidance on when to call this tool versus alternatives such as yardstick_interview_sessions_read or yardstick_interview_sessions_available_interviewers_list. Usage is only implied by the name; no prerequisites, sequencing advice, or exclusions are given.

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