apply_record_template

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

Annotations already indicate the tool is not read-only (readOnlyHint=false) and not destructive, so the description's mention of 'create' aligns. However, the description adds that it returns the new record data, which is beneficial. No additional behavioral details like authentication requirements or rate limits are provided, but with annotations present, the bar is lower.

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 description is a single sentence that is concise and front-loaded with the key verb and resource. Every part is essential: it states the action, the outcome, and the return value with no extraneous information.

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?

Given the tool's simplicity (3 parameters, no output schema), the description sufficiently covers the action and return value. The schema handles parameter documentation, and annotations cover mutation indication. It is complete enough for an agent to use correctly, though it could optionally mention prerequisites like valid IDs.

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?

All three parameters (appId, templateId, debug) are fully described in the input schema with clear descriptions. The tool description does not add extra meaning beyond what the schema already provides, so a baseline score of 3 is appropriate.

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 description clearly states the verb 'apply (instantiate)' and the resource 'record template', specifying the outcome of creating a new record pre-filled with template values. It distinguishes itself from related sibling tools like 'create_record_template' which creates the template itself, and 'get_record_template' which would retrieve template metadata.

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 when you want to create a record from a template, but it does not explicitly state when to use this tool versus alternatives such as directly creating a record or using other instantiation methods. There is no guidance on context or exclusions.

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