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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds the cautionary "when explicitly requested" constraint, consistent with destructiveness, but says nothing about permanence, whether deletion is recoverable, or what happens to guides still in use — all behavior beyond 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?

One short sentence, front-loaded with the action and resource. Nothing is padding, though the trailing qualifier is compressed to the point of being slightly terse.

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?

An output schema exists, so return-value explanation is not required, and the annotations cover idempotency and destructiveness. What remains missing is how to obtain a valid guide_id and any indication of irreversibility, which matter for a destructive one-argument 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?

There is one required parameter, guide_id, with 0% schema description coverage, so the schema conveys only type string. The description does not say where guide_id comes from (list_style_guides / get_style_guides) or what format it takes, leaving the caller to infer everything about the single input.

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?

States a specific verb (Delete) and resource (a workspace style guide), which cleanly separates it from create_style_guide, update_style_guide, get_style_guides, and list_style_guides. It does not explicitly name a sibling it might be confused with, but the verb-resource pairing is unambiguous.

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?

"When explicitly requested" is a real usage gate implying the agent should not delete proactively, which is useful context. However, it names no alternative (e.g., use update_style_guide to modify instead of removing, or get_style_guides to confirm the target) and gives no prerequisites or recovery guidance.

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