init

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

With no annotations and minimal description, the tool's behavior is opaque. It does not disclose whether initialization is required, if it is idempotent, what side effects occur (e.g., creating a session, starting audio), or error conditions.

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 extremely concise: three words conveying the essential purpose. No wasted text.

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 the absence of annotations, output schema, and parameters, the description should cover prerequisites, idempotency, and relationship to sibling tools. It fails to provide sufficient context for an agent to use the tool effectively.

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 input schema has zero parameters, so the description does not need to add semantic meaning beyond what is already clear. The baseline for no parameters is 4.

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 'Initialize Strudel in browser' uses a specific verb ('initialize') and a clear resource ('Strudel in browser'). It distinguishes this tool from siblings which focus on generation, analysis, and manipulation, marking this as a setup/initialization function.

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 guidance is provided on when to use this tool or alternatives. While the purpose implies it should be called once at the start, the description lacks explicit context about prerequisites or ordering relative to other tools.

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