digikey_apply_mylist_changes

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false, and openWorldHint=true. The description adds that exactly one previously reviewed preview is applied, but it largely repeats the idempotency annotation and omits details such as token expiry, failure behavior, or permission requirements.

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 a single front-loaded sentence with no wasted words. It communicates the core action, scope, and idempotent nature efficiently.

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 low-complexity write tool with rich annotations and an output schema, the description is nearly sufficient. It establishes the preview prerequisite and one-preview limitation, though it leaves the preview_token source and error behavior to inference.

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 description coverage is 0%, so the description must compensate for the single preview_token parameter. It links the token to a "previously reviewed preview," which adds useful context, but it does not explain where the token comes from, its format, or its validity window beyond that implication.

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 states a specific verb and resource: apply a previously reviewed preview to DigiKey MyLists. It is clearly distinguishable from sibling preview/read/update tools because it applies a preview rather than creating, validating, or editing one. The scope is also constrained to exactly one preview.

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 phrase "previously reviewed preview" provides clear workflow context: this tool is used after a preview has been reviewed. It does not explicitly name the sibling preview_mylist_changes tool or state when not to use it, so it falls short of full when/when-not guidance.

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