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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is covered. The description still earns credit by disclosing a genuinely non-obvious behavior beyond the annotations: signed URLs are automatically refreshed if expired. It omits failure behavior (e.g., unknown template_id) and any sense of payload size for templates with many layers.

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?

Two short sentences, front-loaded with the core action and the layer scope; the signed-URL note follows as supporting context. No filler, though the second sentence is somewhat tangential to tool selection.

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 one required parameter and full schema coverage this is close to sufficient, but there is no output schema, so the description is the only place to learn what a 'detailed' template looks like. It names layers and refreshed signed URLs but says nothing about other returned fields or error outcomes.

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 100% and the single template_id parameter is documented as a UUID in the schema itself. The description adds nothing further about the identifier (format, where to obtain it), so the baseline of 3 applies.

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?

Specific verb ('Get') plus resource ('a specific template') with the added scope 'including all its layers.' That wording implicitly separates it from layerre_list_templates (which returns summaries) without naming any sibling, so it stops short of full sibling differentiation.

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?

Usage is only implied: an agent infers 'call this when you need full detail for one template.' There is no explicit when-to-use/when-not, no pointer to layerre_list_templates for discovery versus this tool for detail, and no note about what to do with an invalid UUID.

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