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

Annotations declare destructiveHint=true and idempotentHint=true, so the safety profile is already covered. The description adds the crucial reversibility context that reopening is possible, which meaningfully softens and explains the destructive hint. It does not say whether the gap is deleted or merely hidden, so it is good but not rich.

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?

Two short sentences, zero waste, with the action and the distinguishing condition front-loaded before the undo note. Every clause earns its place.

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, no-output-schema tool whose annotations already carry the safety flags, the description supplies purpose, selection condition, and reversibility. Only the gap's post-dismissal state (hidden vs. deleted) is left slightly ambiguous.

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 id and productId are documented with their source tools (list_gaps, list_products). The description adds nothing about the parameters, so the schema-passthrough baseline of 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 concrete action (take an unanswered question off the list) and a decisive qualifier (without writing an article, when it needs none) that separates it from resolve_gap, which presumably produces an article. It also names reopen_gap as the inverse, so an agent can place it precisely in the gap lifecycle.

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?

Gives a clear selection condition: use this when the gap needs no article. The undo path is pointed to explicitly via reopen_gap. It stops short of naming resolve_gap as the alternative for gaps that do need an article, so the routing is strong but not exhaustive.

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