simscale_edge_close

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

The annotations already indicate idempotent, non-destructive, and non-read-only behavior. The description adds that the login profile persists, providing useful context about the tool's side effects beyond the annotation fields. No contradiction.

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 two concise sentences, front-loaded with the action, and adds contextual information about login persistence without unnecessary detail.

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 no-parameter tool with no output schema, the description is complete. It states the action, the managed resource, and the key behavioral detail (profile persistence), which is sufficient for an agent to invoke it correctly.

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?

This tool takes no parameters, and the schema fully covers this (100% coverage). The description does not need to explain parameters, and the baseline of 4 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?

The description clearly states the action ('Close') and the target ('MCP-managed Edge window'), distinguishing it from sibling tools like edge_start and edge_status. It is specific and unambiguous.

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 description implies when to use this tool (to close the Edge window) but does not explicitly state alternatives or exclusions. The note about persistent login provides context but not explicit guidance on when to choose this tool over others. Usage is implied rather than stated.

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