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

With no annotations, the description carries the full burden and does well: it discloses blocking rules (unresolved or partially fixed findings and not_met or unverifiable delivery results block passing), the ownership precondition (reviewRunId must own the current review), and the risk-tiered outcome (low-risk auto-completes, medium/high wait for developer approval). It stops short of saying what the caller receives on success versus rejection.

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 dense sentences, front-loaded with the action and its payload, then constraints, then outcome semantics. No filler, though the middle sentence is heavy and packs schema detail that could be split for readability.

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 7-parameter, no-annotation, no-output-schema mutation tool, the description covers the decision-relevant behavior well but leaves the closure-to-finding mapping and the success/failure response shape undocumented. An agent can call it, but may mis-structure findingClosures on the first attempt.

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 0%, so the description must compensate, and it does explain the repeated finding fields (issue, suggestion, severity, trigger, impact, evidence, optional location) and the reviewRunId ownership constraint. Gaps remain: findingIndex is never explained even though it is the only mechanism linking a closure to a prior finding, and taskId and actorLabel are unaddressed. The mention of "not_met" also does not match any value in the closure status enum.

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 opens with a specific verb and resource ("Pass the claimed review") and enumerates the payload it carries, which cleanly separates it from siblings like request_changes or complete_review. It does not name those siblings explicitly, so the distinction is inferred rather than stated.

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?

It states the conditional path clearly: "When the previous round requested changes, record a closure status for every previous finding." However, it never contrasts this tool with request_changes or complete_review, nor does it say when to call it versus continuing review, so the agent must infer the branch point.

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