controlHide

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

Annotations already declare destructiveHint=true, openWorldHint=true and non-idempotency, so the safety profile is covered. The description adds a genuine new constraint ('trusted owner' and interactive desktop requirement), but it doesn't explain what happens to the control's state or whether hiding is reversible, so it only moderately exceeds the 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 short sentences with zero waste and the identity stated up front. Appropriately sized for a simple three-parameter tool, though the terse phrasing borders on under-specification rather than tight conciseness.

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 three-parameter tool with full schema coverage and no output schema, the environment preconditions are a helpful addition, but the description omits any guidance on return behavior or its relationship to sibling control tools, leaving clear gaps.

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?

Schema description coverage is 100%, with title, control, and text each documented in the schema, so the baseline is 3. The description adds no syntax, format, or selector guidance beyond what the schema already provides.

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 phrase 'Windows AutoIt controlHide' largely restates the tool name rather than independently describing the action of hiding a Window control. The platform context is useful, but it offers no explicit verb+resource statement and does not distinguish it from siblings such as controlShow or winSetState.

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 states an environment prerequisite (trusted owner, interactive Windows x64 desktop) but gives no when-to-use guidance and never contrasts it with the obvious alternative controlShow. An agent must infer the use case entirely from the name.

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