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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is fully covered structurally. The description adds no behavioral context of its own — no indication of what readiness state is computed, what permissions are needed, or what shape the answer takes — so it contributes nothing beyond the 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?

The text is short, but the first two sentences are literal duplicates and carry no information. Brevity here comes from under-specification rather than economy; the operation ID and the describe_operation pointer are the only load-bearing tokens.

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 two-parameter tool with zero schema documentation and no output schema, the description should explain what a readiness result contains and what the query passthrough accepts. Instead it only forwards the agent to describe_operation, leaving the tool effectively unusable without a second call.

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%, and both the 'query' passthrough object and the empty 'params' object are undocumented. The description's only compensating statement is that describe_operation holds the native request schema, which is a useful pointer but does not explain what query parameters this operation accepts or expects.

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 repeats the name verbatim ('GET /api/review/readiness') and adds nothing to explain what 'review readiness' means or what resource it examines. An agent cannot distinguish this from other review-related siblings (get_review_entries, get_review_runs_by_id_*) based on this text.

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?

There is no statement of when to use this tool versus alternatives. The only directional hint, that 'describe_operation provides native request schemas', tells the agent how to obtain a schema, not when this operation is the right choice over siblings such as get_review_entries or get_review_runs_by_id.

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