babelwrap_submit

Submit a form on the current page by specifying a target via natural language or element ID from a previous snapshot.

Instructions

Submit a form on the current page.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
session_idYesThe active session ID.
targetNoOptional natural language description of which form to submit. If omitted, submits the most prominent form. TIP: Pass an element ID from a previous snapshot (e.g. "btn-submit") to bypass LLM resolution entirely for instant, deterministic targeting.
compactNoIf True, return a compact snapshot with minimal whitespace.

Behavior2/5

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. The description only states 'Submit a form' without mentioning potential page navigation, loading states, or destructive actions like data submission, which are critical for an agent's decision.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise but lacks detail. While it is front-loaded and short, the single sentence omits important context that could be added without becoming verbose, such as default behavior or return format.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Although an output schema exists (not shown), the description does not explain return values or side effects of form submission. For a tool with 3 parameters and no annotations, the description is insufficiently complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the description does not need to add parameter meanings. The description does not enhance the schema's parameter explanations, meeting the baseline expectation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's action ('Submit a form') and scope ('on the current page'), distinguishing it from sibling tools like babelwrap_click or babelwrap_fill. However, it could specify which form is submitted without the target parameter.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use or when-not-to-use guidance is provided. The description does not mention alternatives or prerequisites, leaving the agent without context for selecting this tool over others.

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