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

Annotations already declare destructiveHint=true and readOnlyHint=false, giving the safety profile, but the description adds nothing on top of that. It does not say whether stopping is graceful or immediate, whether it is irreversible, whether the process can be resumed, or what state the optimization is left in.

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 short sentence with zero filler and the action front-loaded. It is efficient, though the extreme terseness borders on under-specification rather than tightness.

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 mutation tool with no output schema, the description should cover post-conditions and reversibility. It says nothing about what happens to the running process, whether partial results survive, or what a caller should expect on success, leaving the agent under-informed.

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 all three parameters (processId, reason, customerId) are documented in the schema itself. The description adds no extra meaning such as where to obtain processId or how the superadmin-only customerId behaves, 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 ('Stop') and resource ('optimization process') that an agent can map directly to intent. However, it does nothing to distinguish itself from adjacent siblings such as delete_optimization or trigger_optimization, so the stop-vs-delete boundary is left to inference.

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?

No when-to-use guidance, no prerequisites, and no mention of alternatives like delete_optimization or get_model_optimization_status. The agent must guess whether stopping is the right action or whether deletion is intended.

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