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 then adds genuinely new scope information: the tag is 'detached from documents and templates automatically,' telling the agent the blast radius extends beyond the tag record. It stops short of saying whether deletion is permanent or reversible and what permissions are required.

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 purpose sentence is front-loaded, followed by a tight trigger and a side-effect sentence — every sentence earns its place. The single-item bulleted 'Use this tool when' block is slightly heavy for one condition.

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?

With rich annotations, a documented single parameter, and an output schema, the description covers purpose, trigger, and downstream effects adequately. The main residual gap for a destructive operation is that permanence/undo options are never stated.

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?

Only one parameter exists and schema description coverage is 100% ('UUID of the tag to delete'), so the schema fully carries parameter meaning. The description adds nothing beyond it, which is acceptable at this coverage level but earns only the baseline.

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 and resource ('Delete an existing tag'), so the operation is unambiguous. The title/name scope it to account-level tags, but the description itself never says 'account' and doesn't distinguish this from update-account-tag or from tag-removal via update-document-tags, leaving sibling differentiation to the tool name.

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?

Provides an explicit trigger: 'Use this tool when: The user explicitly asks to delete a tag,' which sensibly guards against inferred deletion. It gives no when-not condition or named alternative (e.g., removing a tag from one document instead of deleting it account-wide), so routing is clear but not complete.

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