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

Goes well beyond the annotations (which only say non-readOnly, non-destructive, non-idempotent) by disclosing atomic single-shot claiming with no races, priority/age ordering, null-on-empty return, and single-workspace queue consumption. These are exactly the mutation semantics an agent needs.

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?

The core action and ordering are front-loaded, but the text is dense with some redundancy ('de una sola vez y sin carreras') and the agentCloseState explanation is tangential and ambiguous (not a listed parameter), adding noise to an otherwise efficient block.

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 mutation tool with no output schema, the description covers the return value (claimed issue with context or null), the required follow-up (release_issue), close-state handling, and workspace/project scoping — everything needed to invoke and reason about results.

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?

With 0% schema coverage, the description must compensate and largely does: it explains workspaceId's default-from-credential behavior and one-workspace-only scope, and projectId's product/initiative expansion. It could still specify id format, and the agentCloseState tuple is referenced without tying it clearly to a parameter or return field.

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 precise verb and resource: atomically pops and claims the next free issue from the 'ready-for-agent' queue. It defines the selection order (priority then oldest) and the return value (claimed issue or null), making it clearly distinguishable from a targeted claim_issue.

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?

Explains the full workflow — claim, work, release with release_issue — and clarifies workspaceId defaults and projectId scoping. It doesn't explicitly contrast with the sibling claim_issue (targeted claim), so the alternative-routing guidance is implied rather than stated.

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