workflow_claim_task

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

With no annotations, the description carries the full burden. It does disclose genuine behavior: the claim is a lease and that lease is bounded, and it signals ordering relative to reasoning. It omits what happens on lease expiry, conflict handling, or the optimistic-concurrency meaning implied by expectedVersion, leaving notable gaps.

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 tight sentence with the action front-loaded and zero filler. Nothing here wastes the agent's attention.

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?

A mutating coordination tool with no annotations, no output schema, and 0% parameter coverage needs considerably more than one sentence. Key facts an agent must know, lease semantics, expiry, and expectedVersion handling, are absent.

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 0%, so the description must compensate and does not. "bounded lease" loosely gestures at leaseMinutes but never names it or its default/limits, and expectedVersion (clearly an optimistic-locking token) is never explained. taskId is self-evident at best.

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 ("Claim") and resource ("task") plus a distinguishing scope ("with a bounded lease"). It separates itself reasonably from siblings like workflow_complete_task or workflow_get_task_context, though it never explicitly names an alternative.

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 phrase "before local Copilot reasoning begins" implies sequencing/context for invocation, giving some usage guidance. However, it names no alternatives and states no explicit when-not or prerequisite conditions, so usage is only implied.

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