Field Config Create

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

With no annotations, the description carries the full behavioral burden. It does not disclose permission requirements, whether the new configuration is immediately active, what happens on name collisions, or any side effects of creating a field configuration. 'Create' implies mutation, but no further behavioral details are provided.

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 single sentence is brief and front-loaded, but it is under-specified rather than an efficient summary. It uses minimal space while omitting essential information for invoking an 8-parameter creation tool.

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?

For a tool with 8 parameters, 5 required, no annotations, and no schema descriptions, the description is far too sparse. Even with an output schema covering return values, the agent gets no guidance on what the required parameters mean or how this creation tool interacts with sibling field tools.

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% and the description mentions no parameters at all, despite 8 parameters including 5 required fields (field_name, field_type, entity_type, bundle, label). It adds no semantic meaning to field_name, label, bundle, settings, or required beyond the bare schema names.

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?

States a specific verb and resource ('Create a new field configuration'), making the basic action clear. However, it does not distinguish this tool from sibling field configuration tools such as field_config_update or field_config_delete, leaving the agent to infer it is the creation variant.

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 given on when to use this tool versus field_config_update, field_config_get, field_storage_create, or other configuration tools. The description provides no prerequisites, no context about bundles or entity types, and no exclusions.

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