get_field_definition

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

No annotations provided, so description carries full burden. It mentions returns or error but does not disclose behavioral traits like permissions, rate limits, or side effects. Adequate for a read operation but minimal.

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?

Concise, front-loaded with main purpose, structured with Args and Returns sections. No extra fluff, though the Args section repeats parameter names already in schema.

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?

Output schema exists but not shown;description lists return attributes adequately. However, lacks context on how this tool relates to siblings like 'list_dictionary' or 'describe_file'. Adequate for its narrow scope.

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 coverage is 0% with no parameter descriptions. Description adds 'Args' section with meaningful text: 'Name of the Universe file' and 'Dictionary field/item name', compensating well for missing schema details.

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?

Description clearly states the verb 'get' and resource 'dictionary field', specifying it returns detailed definition. Distinguishes from sibling 'list_dictionary' which lists fields.

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?

Description implies use for a single field's detailed definition but does not explicitly contrast with siblings like list_dictionary or when not to use. Lacks explicit when-to-use or when-to-avoid guidance.

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