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

Description adds transparency beyond annotations: states runtime-only, non-persistent, resets on reload, and no code changes needed. This aligns with idempotentHint and provides practical behavior context for an AI agent.

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 concise sentences, no redundancy, front-loaded with key information. 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 4 optional parameters and no output schema, description covers purpose, behavior, and temporal scope. Could mention default mode handling, but sufficiently complete for a lightweight debugging tool.

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 covers all 4 parameters with descriptions (100% coverage). Description does not add extra parameter meaning, so baseline score of 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?

Description states specific verb 'Highlight' with resource 'object for debugging' and clarifies two modes (wireframe or visibility toggle). It clearly differentiates from sibling tools like toggle_wireframe by focusing on specific object selection and including visibility mode.

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 'Debug only' and 'page reload will reset', guiding use to temporary visual inspection. Lacks explicit when-not-to-use or alternative tools, but context is clear enough.

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