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

No annotations are provided, so the description carries full responsibility for disclosing behavior. It mentions the founder-cell permission but doesn't describe side effects, whether the rebuild is destructive, whether it can be undone, or what happens after invocation. For a 'rebuild' action, this is a significant transparency gap.

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 short sentences deliver the core purpose and the key constraint with no filler. The action is front-loaded and every word adds useful information.

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 zero-parameter tool with no output schema, the description provides enough to understand the action and the main usage restriction. It leaves the post-conditions and internal effects to inference, which is acceptable for such a minimal interface.

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?

There are zero parameters and the schema is empty, so schema coverage is effectively 100% and no parameter semantics are needed. The description appropriately adds no parameter details because there are none to document.

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 action ('Trigger a Mac mesh rebuild') and environment ('from the IDE'), so an agent can identify what the tool does. It doesn't explicitly differentiate from sibling tools, but none of the listed siblings appear to perform a mesh rebuild, so the risk of confusion is low.

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 'from the IDE' phrase gives some context for when this is appropriate, and 'Only permitted on the founder cell' imposes a clear access restriction. However, it doesn't explicitly describe when to choose this tool over alternatives or when not to use it beyond the permission constraint.

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