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

Annotations already declare the mutation/safety profile (readOnlyHint false, idempotentHint false, destructiveHint false), so the bar is lower. The description adds genuinely useful context beyond that: the request is queued for asynchronous manager review, and a confirmation with disposition details is returned.

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 clauses with the core action front-loaded and no filler. The final sentence about the return confirmation is partly redundant given an output schema exists, which keeps it from a 5.

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 tool with a full schema, output schema, and mutation annotations, the description supplies the one thing the structured data cannot: that approval is deferred to a manager. Nothing needed to invoke it correctly is missing.

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% for the single 'feature' parameter, including its 20-1000 character constraint, so the schema carries the load. The description adds no additional meaning about the parameter, which is the expected baseline when the schema 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?

A specific verb+resource ('Submits a request to add a new feature or improve an existing one') makes the action unambiguous, and the scope is clearly feature requests rather than tests. It does not explicitly name or contrast with the sibling request tools (requestNewTest, requestRetest), so it stops short of full sibling differentiation.

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?

'Queued for manager review' plus 'There is no immediate-approval alternative for feature requests' tells the agent when to use this and preempts a search for a faster path. It stops short of a 5 because no explicit when-not-use case or named alternative is given.

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