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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond 'reusable' – no note on scope/permission requirements, whether payloadDefaults are inherited by derived QRs, or tenant-vs-company visibility implications. With annotations present the bar is lower, but the description still contributes almost no extra behavioral context.

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?

A single front-loaded sentence with zero filler; nothing is redundant. Its brevity is clean, though it is arguably too terse for a six-parameter mutation, which pushes it just below a 5.

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 mutation tool with no output schema, 33% schema coverage, a nested free-form payloadDefaults object, and four sibling template tools, the description leaves too much unexplained – no return behavior, no scope/permission context, no linkage to the template-consuming tools. It is inadequate for the tool's complexity.

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 only 33% – scope and qrType are documented, but designId, description, and the nested payloadDefaults object are undocumented in both schema and description. The description mentions no parameters at all and therefore does nothing to compensate for the coverage gap, which matters most for the opaque payloadDefaults object.

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+resource (create + template) and adds the meaningful qualifier 'reusable,' so the agent knows this produces a stored, reusable asset rather than a one-off render. It does not distinguish itself from templates_update/templates_get/templates_list beyond the verb, but the name/verb pairing makes the intent unambiguous.

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?

No when-to-use guidance, no prerequisites, and no mention of alternatives. The agent gets no hint that qrs_create_from_template is the consumer of what this tool produces, or when to prefer creating a template over qrs_create directly.

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