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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds genuine context beyond that: events are immutable, results are capped at 20, older decisions are historical and do not approve a new draft, and the material is internal — all useful for correct interpretation.

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?

Three front-loaded sentences plus a short qualifier, each carrying distinct information (content, pagination, interpretation caveat, audience). Slightly dense phrasing ('Follow nextCursor as beforeId') but no filler.

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?

There is no output schema, so the description must convey the return shape, and it does: events with authors, decisions, pinned draft revisions, plus a nextCursor. Combined with the immutable/20-event/historical framing, an agent has enough to call and interpret this tool correctly.

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 50%: projectId is documented in the schema, but beforeId is not. The description compensates by explaining that nextCursor should be passed as beforeId, which is the key semantic the schema omits. It adds nothing further about the projectId format, but that is already covered.

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: reads sentence-review events, with scope (20 per page) and content (authors, decisions, pinned draft revisions). It is clearly distinguished from the sibling read_draft_review by being a paginated history, though it never names that sibling explicitly.

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?

The description implies usage through the pagination instruction and the caveat that older decisions do not approve a new draft, which tells the agent how to interpret results. However, it gives no explicit when-to-use versus read_draft_review or other review-reading siblings, and no stated prerequisites.

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