Update global custom field

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

The description only states "Update" without specifying which attributes can be changed (name, config), what happens to omitted fields, or whether the operation is idempotent. No annotations are provided to mitigate these gaps.

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 but omits valuable information. It front-loads the HTTP method and path, which may be redundant for agents familiar with REST APIs, but overall lacks substance.

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?

Given the complexity of the input schema (nested objects, conditional fields) and the lack of output schema or annotations, the description fails to provide enough context for an agent to confidently invoke the tool. No information about response format or side effects is given.

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%, meaning the tool description adds no explanation for parameters. Although the schema itself contains some inline hints (e.g., "Required if type = currency"), the description does not clarify parameter meaning or usage beyond 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 states "Update global custom field" with the HTTP method and path, clearly identifying the action and resource type. It distinguishes from sibling tools like create, delete, or get for global custom 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?

No guidance is provided on when to use this tool versus alternatives like transfer_global_custom_field_to_board or update_global_custom_field_option. There is no mention of prerequisites or contextual use cases.

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