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

Annotations already declare readOnlyHint=false, idempotentHint=true and destructiveHint=false, so the safety and repeatability profile is covered. The description usefully adds the eligible source states (dismissed or drafted), but says nothing about side effects on draft content, permissions, or the outcome of calling it on an ineligible question.

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 sentence with the action and the eligible states front-loaded and no wasted words.

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 simple two-parameter state toggle whose parameters are fully documented and whose safety profile is carried by annotations, the description covers what an agent needs. It could still note whether reopening restores prior draft content or fails on already-open questions.

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%: both productId and id are documented in the schema, including the source tools (list_gaps, list_products). The description adds no format or constraint detail beyond that, so the baseline 3 applies.

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 action (put back on the list) applied to a specific resource (a dismissed or drafted question), which an agent can readily separate from dismiss_gap and resolve_gap by state. It does not name those siblings explicitly, so it stops short of a 5.

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?

Usage is implied by the state precondition: reopen applies to questions that are dismissed or drafted. There is no explicit when-to-use versus alternatives, no statement of what happens if the question is already open, and no prerequisite call ordering.

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