Update a JsonFabrica template

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

The description discloses a key behavioral trait: only provided fields are changed, indicating partial-update rather than full-replace semantics. It also reveals the HTTP method and endpoint. However, with no annotations at all, it does not cover authentication requirements, return values, error behavior, or side effects, leaving notable transparency gaps.

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 extremely concise: two short sentences with no filler. The endpoint and the partial-update behavior are both front-loaded and meaningfully informative.

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 there is no output schema, no annotations, and 0% parameter documentation, the description is too sparse for an agent to call the tool correctly with confidence. It provides the endpoint and partial-update semantics but omits parameter meanings, required identifiers, return shape, and operational context.

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, but it does not. It never mentions templateId, body, name, tags, or description, and 'provided fields' is only a generic abstraction. An agent gets no parameter-level guidance from the description.

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 operation: updating a JsonFabrica template via PUT /v1/templates/{templateId}. The phrase 'Only the provided fields are changed' also signals partial-update semantics, which helps distinguish it from create or delete siblings. However, it does not explicitly name alternative tools or contrast them.

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?

There is no guidance on when to use this tool versus jsonfabrica_create_template, jsonfabrica_get_template, or jsonfabrica_delete_template. No usage context, prerequisites, or exclusion conditions are provided. The description implies an update scenario but never states it.

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