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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered structurally. The description adds that scope is limited to the connected organization and that approval requirements are admin-configurable, but that approval note is generic boilerplate with no concrete consequence for a read-only list call.

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 sentences, none wasted on repetition, but the core purpose statement is buried behind a generic boilerplate preamble and an approval clause that adds little. Leading with "Read reusable purchase-list templates" would be stronger.

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 values need not be described. For a zero-required-parameter list tool with full annotation coverage, the description is largely sufficient; the main gap is that paging and search behavior are never characterized.

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 needs to explain limit, offset, and search — and it explains none of them. Notably, what 'search' matches against is undocumented anywhere, and default/max paging behavior is left entirely to the schema constraints.

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 second sentence states a specific verb and resource: "Read reusable purchase-list templates." It is reasonably distinguishable from create_purchase_template and get_purchase_template, though it never explicitly contrasts with list_purchase_template_items, which is the closest sibling an agent could confuse it with.

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 opening line ("Use this when working with RetailHardHat purchase_lists records") is context, not guidance — it does not say when to pick this over get_purchase_template or list_purchase_template_items. No conditions, prerequisites, or exclusions are given.

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