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

No annotations are provided, so the description carries the full burden. It mentions 'Smart identifier resolution' which adds useful context about input flexibility, but fails to disclose critical behavioral traits such as whether this operation is destructive, irreversible, requires specific permissions, or has side effects. For a deletion tool with zero annotation coverage, this is a significant 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?

The description is front-loaded with the core purpose, followed by brief but informative sections for Args and Returns. Every sentence earns its place with no wasted words, making it highly efficient and well-structured.

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 a deletion tool with no annotations, 0% schema coverage, and no output schema, the description is moderately complete. It covers the purpose and parameter semantics well but lacks behavioral transparency and detailed usage guidelines, leaving gaps in understanding the tool's full context and implications.

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?

With 0% schema description coverage and only 1 parameter, the description adds substantial value by explaining that 'zone_identifier' accepts 'origin domain, CDN domain, or UUID'. This clarifies the parameter's semantics beyond the basic schema type, though it doesn't detail format constraints or examples.

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 specific action ('Remove SSL certificate') and resource ('from a CDN zone'), distinguishing it from siblings like 'delete_cdn_zone' or 'delete_ssl'. It precisely defines what the tool does without being vague or tautological.

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 for removing SSL certificates from CDN zones but doesn't explicitly state when to use this tool versus alternatives like 'disable_auto_ssl' or 'delete_ssl'. It provides some context through 'Smart identifier resolution' but lacks explicit when/when-not guidance or named alternatives.

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