Generate a document from a JsonFabrica template

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

No annotations are provided, so the description carries the full burden. It usefully discloses that generation can have sequence/variable side effects and explains how to isolate them across environments. However, it does not describe the response format, whether the operation is idempotent, or how seed, params, and context affect generation.

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 concise: two sentences, no filler, with the core operation and endpoint first and the namespace guidance second. It is efficiently structured, though the endpoint duplication is slightly redundant with the title.

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 six parameters, no annotations, no output schema, and nested objects, the description is too sparse to be fully actionable. It provides minimal context about parameter semantics, return values, and edge cases, leaving significant gaps for an agent to infer.

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 must compensate for parameter meaning. It only clarifies sequenceNamespace and variableNamespace, leaving seed, params, context, and even templateId without added explanation. With two nested object parameters and no semantic guidance, an agent cannot confidently construct a correct invocation.

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 states a specific verb and resource: 'Generates a document using a persisted template.' The endpoint is also given, making the operation explicit. It hints at a distinction from generate_adhoc via 'persisted template,' but the sibling tool is not named, so differentiation is not fully explicit.

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?

It gives a concrete configuration instruction: 'Set sequenceNamespace/variableNamespace to isolate sequence/variable side effects between environments.' However, it does not explain when to choose this tool over generate_adhoc or other siblings, nor does it state any exclusions or prerequisites. The use case is implied by 'using a persisted template,' but not elaborated.

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