field

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

No annotations are provided, so the description carries the full burden, and it largely does not. It never states side effects (e.g. whether remove deletes the field permanently – only the keep_text parameter hints at it), whether edits are saved, what authorization or handle context is needed, or what non-read actions return.

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?

Extremely compact and front-loaded: one short resource clause followed by the action menu. The dense signature notation is efficient, though its terse style makes it slightly harder to parse than plain prose would be.

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 6-action, 11-parameter dispatcher with no annotations and no output schema, the description covers the action surface and per-action parameter mapping, which is the core need. It still omits return behavior, error cases, and the meaning of several parameters, so it is adequate but not full.

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 only 27% across 11 parameters, so the description must compensate and partly does: it maps each parameter to its action and marks optionality with '?' (e.g. set(value, name?, target?), remove(name, keep_text?)). However, it never explains what values, guide, or memo actually contain, leaving key semantics undocumented.

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 names the resource (누름틀·셀 필드, i.e. form/click-here fields) and its purpose (양식 채우기, form filling), then enumerates the six actions. That is enough to know roughly what the tool does, but it is essentially an API signature dump, and nothing distinguishes it from siblings like table, text, or document beyond the resource noun.

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?

There is no statement of when to use this tool versus alternatives, no prerequisites, and no exclusions. The action list hints at per-action usage (get by name, set by value), but that is schema-level enumeration rather than selection guidance for the agent.

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