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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so safety and replay semantics are covered. The description adds genuinely new behavioral context - that editing reverts to default behavior until a new style is saved - rather than repeating the annotations. It stops short of saying whether the deletion is reversible or what happens if no style exists.

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 short sentences, action front-loaded before the consequence. The parenthetical "(when the user asks)" is slightly redundant with the imperative voice, but nothing else is wasted.

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 simple destructive delete with no output schema and annotations already carrying the safety profile, the description supplies the key post-condition. It omits error/not-found behavior and reversibility, which are minor gaps for this complexity level.

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 coverage is 50%: idempotencyKey is fully documented in the schema, while workspaceId has no description. "this workspace's" lightly implies the workspaceId parameter's meaning but adds no format or constraint detail beyond the schema. Baseline 3 with partial coverage 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?

Specific verb+resource ("delete... saved edit style") scoped to the workspace, and clearly distinct from its nearest siblings get_edit_style, save_edit_style and delete_style_examples. An agent can select it without opening the schema.

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 parenthetical "(when the user asks)" gives a trigger condition, which is more than most delete tools offer, but there are no exclusions or named alternatives (e.g., distinguishing it from delete_style_examples or from simply not using a style). Usage is implied rather than fully specified.

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