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

Annotations provide basic safety hints (readOnlyHint false, destructiveHint false). Description adds value by explaining the underlying mechanism (real OS keyboard events) and the reliability benefit over synthetic Ctrl+A, without contradicting 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, zero wasted words. Front-loaded with action and mechanism, followed by prerequisite and platform note.

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 no parameters, no output schema, and adequate annotations, the description covers the tool's purpose, prerequisites, platform, and behavioral nuance completely.

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?

No parameters; schema is empty (100% coverage). Description adds meaning beyond schema by explaining the action's nature. Baseline for 0 params 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?

Description clearly states the tool clears a focused rich/contenteditable editor using real OS keyboard events, with specific verb 'clears' and resource 'focused editor'. It also distinguishes from synthetic methods.

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 says 'Focus the field first with `click`' and 'Windows only', providing clear prerequisites and platform constraint. No mention of alternatives, but context is sufficient.

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