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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds only the notion that results are "privacy-filtered," which hints at data-scoping behavior but is too vague to be actionable. With annotations carrying the burden, this is an acceptable but thin contribution.

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?

A single short sentence with the operation front-loaded and no padding. It is efficient, though the "privacy-filtered project metadata" clause is filler that consumes space without adding meaning.

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 tool with full schema coverage and annotations, the description is minimally viable but omits what a change review is, how results are scoped or ordered, and how it relates to the single-review getter. No output schema exists, so the description could have carried more return-shape context but does not.

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%, so the schema already documents cursor, pageSize, projectId, and the filter parameters, establishing a baseline of 3. The description adds nothing about parameter meaning or filtering semantics. Note the schema itself has copy-paste defects (reviewId/sessionId/executionId all describe themselves as "Owned project ID"), which the description does not clarify.

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 pairs a verb ("Read") with a resource ("list change reviews"), so the basic operation is identifiable. However, the modifier "hosted" and the phrase "using privacy-filtered project metadata" are vague and do not differentiate this tool from siblings like get_change_review or create_local_change_review. An agent cannot tell from the text when this list tool is preferred over the single-review getter.

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 explicit when-to-use guidance, no prerequisites, and no mention of alternatives such as get_change_review (single) or create_local_change_review (creation). The only implicit signal is "list" implying bulk retrieval. This falls short of actionable usage guidance.

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