create_a_schema

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

Annotations already provide readOnlyHint=false, idempotentHint=false. The description adds 'Not idempotent' and 'may create duplicates,' which aligns with annotations but does not reveal additional behavioral traits such as authorization needs or side effects.

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 plus a header. It front-loads the purpose and includes key metadata (WRITE, creates data, endpoint). No wasted words.

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?

No output schema exists, and the description does not mention return values, error conditions, or success indicators. For a creation tool with nested objects, more context about the response would improve completeness.

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?

Input schema coverage is 100% (all parameters described in schema). The description adds no parameter-specific information beyond what is already in the schema.

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 'Create a schema' and mentions 'Custom Objects' and the endpoint. However, it does not distinguish this tool from sibling tools like 'create_a_child_schema' or 'create_a_public_schema', which reduces clarity for an AI agent selecting among similar options.

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 on when to use this tool versus alternatives (e.g., child or public schema creation). No prerequisites or context for when it is appropriate to create a schema via this endpoint.

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