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

Annotations already declare destructiveHint=true and idempotentHint=false, so the safety profile is carried by structured data. The description adds genuinely new context: that dependent records may be affected and that approval requirements (MCP-level configurable, plus always-on workflow approvals) apply — information not present in annotations and directly relevant to a delete.

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?

Three short sentences, front-loaded with the action and the caution. The approval sentence is slightly boilerplate but still conveys real constraints, so it earns its place reasonably well.

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 and annotations cover the safety profile, so the description only needs to add the delete-specific caveats — which it does via dependent records and approval requirements. It stops short of saying whether the deletion is permanent or recoverable, which an agent would want for a destructive 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 parameter with 0% schema description coverage, and the description says nothing about it — not that it is the checklist item's UUID nor where to obtain it (e.g., from list_checklist_items). With low coverage the description was expected to compensate and does not.

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 concrete verb and resource: delete a checklist_item instance. The name distinguishes it from the sibling delete_checklist_template_item, but the description itself never explicitly says it acts on a site/project checklist item rather than a template item, leaving a small ambiguity an agent must resolve from the 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?

The description implies usage ('review dependent-record effects before confirming') but gives no when-to-use/when-not guidance and does not point at alternatives such as delete_checklist_template_item or archive-style options. Usage is inferable from the destructive verb, but nothing is stated explicitly.

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