render_template

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

With no annotations provided, the description carries the full burden. It states the core behavior (rendering a template with variables) and adds explanatory context, but does not disclose details like in-memory processing, failure modes, or output format. The presence of an output schema mitigates some of this, so a 3 is appropriate.

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 sentences: the first is the core purpose, the second adds relevant domain context. No redundant phrasing or unnecessary detail. Every word earns its place.

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?

The tool is simple, the schema covers parameters, and an output schema exists. The description clearly conveys purpose and typical use, making it complete enough for an agent to select and invoke correctly. It loses one point for not explicitly addressing how it differs from sibling template tools, but this is not critical.

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 coverage is 100%, so the schema already documents both parameters. The description's phrase 'provided variables' adds no new meaning beyond what the schema provides. Baseline 3 applies because the schema handles parameter documentation.

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 starts with 'Render a Jinja2 template with provided variables' – a specific verb and resource. It clearly distinguishes this rendering operation from sibling template management tools like create_template, update_template, and describe_template.

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 provides context about Jinja2 usage in network automation, implying when templates might be used. However, it does not explicitly state when to choose render_template over sibling template management tools, nor does it exclude scenarios like persisting templates.

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