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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false; the description adds real context on top by spelling out the DRAFT→SUBMITTED transition, the caller-identity restriction, and the feature-tier requirement. It doesn't explain downstream effects (approval routing, notifications, or why the operation is flagged destructive), which would be needed for a 5.

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?

Three tight sentences with the core action first, then the permission constraint, then the feature gate. No filler and nothing buried.

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 single-parameter mutation with no output schema, the description covers the action, the resulting state, the authorization rule, and the edition requirement. It stops short of describing failure modes or side effects (who gets notified, whether review starts automatically), which would make it fully self-sufficient.

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?

Only one parameter and schema coverage is 100%, so the schema already carries 'ID of the change request to submit.' The description adds no format, sourcing, or lookup guidance for changeRequestId, 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?

States a specific verb (Submit), the exact resource (a DRAFT change request), and the resulting state transition (moves it to SUBMITTED). This distinguishes it cleanly from create_change_request, submit_cr_review, implement_change_request and withdraw_change_request without needing to open any schema.

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 hard precondition ('Only the original requester can submit') and a licensing gate (changeControl ENTERPRISE+), which tells the agent when the call will be rejected. It does not explicitly name alternative tools for other actors (e.g. a CCB member path), so it falls short of full when/when-not routing.

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