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

No annotations are provided, so the description must fully disclose behavioral traits. It does not state whether this operation mutates data, commits changes, or has side effects; saying 'retrieving updated schema' hints at a read operation, but 'finalize' suggests potential state changes. Permissions, reversibility, and error behavior are not mentioned.

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 a concise docstring with Args and Returns sections. It avoids fluff and front-loads the core purpose. The structured format is slightly verbose but each element earns its 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?

With no annotations, the description is the only source of behavioral context. It covers parameters and return type but omits side-effect details, prerequisites, and error handling. Given the simple parameter set (3 params, no enums) and presence of an output schema, it is minimally viable but not fully complete.

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%, but the description explicitly explains each parameter's purpose, including that 'project_key' uses a global tenant_id if not provided. This adds meaningful semantics beyond the bare schema titles, compensating for the lack of inline schema descriptions.

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 a specific action ('Finalize schema changes') and resource ('schema'), and positions it as 'step 3 of schema field management', which distinguishes it from sibling tools like create_schema or update_schema_fields. However, the exact meaning of 'finalize' is not elaborated, leaving some ambiguity.

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?

The description gives clear context that it is part of a multi-step workflow ('step 3 of schema field management'), implying when to use it in sequence. It does not explicitly list exclusions or alternatives, but the step-oriented wording provides adequate guidance.

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