create_node

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only says the tool creates a node. It does not mention side effects, prerequisites (e.g., existing parent category), validation behavior, uniqueness constraints on slug, or what the response contains.

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 compact with no filler. The purpose sentence is front-loaded and the only additional sentence points out an optional parameter, so both parts earn their 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?

For a mutating tool with five parameters, no annotations, and no output schema, this description is severely incomplete. It omits the semantics of all required parameters, expected behavior on failure, return value, and any dependencies such as a valid parent category.

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 only 20% because only color is documented in the schema. The description repeats that color is optional but adds no meaning for the four required parameters: name, description, slug, and especially parent_category_id.

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 uses a specific verb and resource ('Create a new node') and clarifies the domain term with '(nested community)', which differentiates it from other creation tools such as create_topic or send_private_message. The purpose is immediately understandable to an agent.

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?

No guidance is given about when to use this tool versus alternatives, when not to use it, or which sibling tools cover related cases like listing nodes or checking a slug. An agent must infer applicability solely from the name and schema.

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