Select TraeCN Mode

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

Annotations already provide idempotentHint true and destructiveHint false. The description adds a useful behavioral detail: switching to the current mode is a no-op. It also mentions confirming the result, which is extra context. No contradiction with annotations.

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?

Two sentences deliver the core action, the output confirmation, and the usage condition without any fluff. The key instruction is front-loaded and every sentence earns its place.

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?

Given a single parameter with full schema coverage and an output schema (presumably conveying the confirmed mode), the description covers the necessary aspects: what it does, when to call it, and the no-op edge case. Nothing critical 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?

The schema fully documents the 'mode' parameter with an enum and description (100% coverage). The tool description adds no additional parameter semantics beyond the no-op behavior, which is more about tool behavior than parameter meaning. Baseline 3 is appropriate.

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 uses a specific verb ('Switch') and names the exact resource and modes ('TraeCN between Solo and IDE mode'). It also adds the confirmation of the resulting active mode, fully distinguishing this tool from any sibling that deals with other aspects.

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?

Explicitly states the condition for invocation: 'Call only when the requested mode differs.' This gives clear direction on when to use the tool and implicitly when not to (when modes match), which is a precise usage guideline.

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