v0.3.3Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations mark it as readOnlyHint=true, and the description confirms it returns version info and license status. It adds context about the specific output, which is beyond what annotations provide.
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 with no redundant information. The purpose is front-loaded, and every sentence adds value.
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 tool with zero parameters and a clear purpose, the description fully explains what the tool does and returns. An output schema exists to detail return structure, so no further information is needed.
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 exist, so schema coverage is effectively 100%. The description does not need to add parameter information; baseline score of 4 applies due to high schema coverage.
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 clearly states the verb 'Verify' and the resource 'Screaming Frog SEO Spider installation and CLI accessibility'. It distinguishes itself from siblings by focusing on installation status rather than crawl operations.
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 implies usage before other crawling operations but does not explicitly state when to use or not use this tool versus alternatives. No guidance on prerequisites or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
