Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
nameYes
fieldsYesArray of field definitions for the content type
descriptionNo
displayFieldNo
spaceIdYesThe ID of the Contentful space. This must be the space's ID, not its name, ask for this ID if it's unclear.
environmentIdYesThe ID of the environment within the space, by default this will be called Mastermaster
Behavior1/5

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

No annotations provided, and the description does not disclose any behavioral traits (e.g., whether creation is idempotent, required permissions, or side effects). The agent has no information beyond the fact that it creates.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single short sentence, which is concise but omits essential information. It does not earn its place by being informative.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (6 parameters including nested field arrays) and sibling tools, the description is grossly inadequate. It provides no context about return values, error conditions, or the content type creation process.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50%, but the tool description adds no explanations for the three undocumented parameters (name, description, displayField). It fails to compensate for the schema gaps.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description restates the tool name ('Create a new content type' is a direct paraphrase of 'create_content_type'), providing no additional specificity or distinction from siblings. It is a tautology.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs. alternatives like update_content_type or create_entry. No context about prerequisites or typical scenarios.

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