Checkout DevOps Center Work Item

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

The description adds the specific behavior of moving the work item to 'In Progress' status, which is beyond what annotations provide (readOnlyHint=false, idempotentHint=true, destructiveHint=false). It does not disclose additional details like permission requirements or reversibility, but given the annotations cover the safety profile, this is adequate.

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 description is succinct and front-loaded with the action. The parameter line is redundant with the schema, adding slight waste, but overall it is concise and well-structured.

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 single-parameter mutation tool with annotations and no output schema, the description adequately covers the purpose, state change, and usage context. It does not mention edge cases like already-checked-out items, but for this complexity, it is reasonably complete.

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%, and the description's parameter line ('workItemId: DevOps Center work item ID to check out') exactly repeats the schema description. No additional semantic meaning is provided beyond the schema, 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?

The description clearly states the specific action (checks out a DevOps Center work item) and the resulting state change (moving it to 'In Progress' status). This distinguishes it from sibling tools like commit, promote, or create, which have different purposes.

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 description provides clear context for when to use the tool: when a developer is actively starting work on a work item. However, it does not explicitly mention alternatives or exclusions (e.g., when not to use it), so it falls short of a 5.

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