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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the safety profile is covered by structured data. However, the description adds nothing beyond that: it doesn't disclose irreversibility, cascade effects, required permissions, or what happens on a repeat/cross-referenced call.

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?

One short, front-loaded sentence with no waste, but also no substance. It is concise to the point of being under-specified for a destructive operation.

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 destructive, non-idempotent mutation with no output schema and no annotations explaining consequences, the description should say more about irreversibility and side effects. It leaves the agent without the context needed to use a delete safely.

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?

The single 'id' parameter has 100% schema description coverage ('Id of the Work.'), so the schema carries parameter semantics. The description adds no format or sourcing detail, which is the expected baseline when schema coverage is complete.

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 states a clear verb+resource ('Delete a work item'), but it merely restates the tool name and title without distinguishing it from the many other delete_* siblings (delete_batch, delete_idea, delete_project, etc.). An agent knows what it does but not what makes it the right 'delete' tool.

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?

There is no guidance on when to use this tool versus alternatives. Notably, archive_* siblings exist for several resources, and delete future-proof guidance (or a note that deletion is permanent versus archiving) is absent, leaving routing entirely to inference.

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