solver_cancel

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

No annotations are provided, so the description bears the full burden of disclosing behavior. It only restates the cancel action and the endpoint, without explaining whether cancellation is asynchronous, idempotent, reversible, or what side effects it has on the execution and related resources. This is a meaningful gap for a mutating operation.

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 a single front-loaded sentence with no filler. Every word earns its place: it names the action, the target resource, and the endpoint.

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 one-parameter tool with no output schema, this description covers the essential invocation details and the condition for use. However, the missing behavioral and post-condition information leaves the description incomplete for an agent that needs to reason about the consequences of cancellation.

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 schema only describes execution_id as a required string, and the description provides minimal extra context by tying it to the execution resource in the endpoint. With 0% schema description coverage, the description slightly compensates but does not clarify format, source, or expected value conventions.

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 specific verb ('Cancel') and resource ('running execution') and includes the exact HTTP endpoint. This clearly distinguishes it from sibling tools such as solver_status or solver_submit, which share the execution domain but not cancellation behavior.

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 phrase 'running execution' gives a clear precondition: use the tool only when an execution is actively running. It does not name explicit alternatives or say when not to use it, but for a single-purpose cancel endpoint this is sufficient contextual guidance.

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