Find Element

element_find
Read-onlyIdempotent

Locate a web page element by CSS selector, XPath, or text match. Waits for the element to appear within a set timeout.

Instructions

Find an element on the page using CSS selector or XPath. Bare selectors are treated as CSS; use text:... for text matching.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
tab_idNoOptional MCP or native DrissionPage tab id. When omitted, the current tab is captured at call start.
timeoutNoTimeout in seconds to wait for element
selectorYesCSS selector or XPath to find the element. Bare selectors are CSS; use text:... for text matching or explicit tag:/css:/xpath:/@attr locators.

TDQS

B3.2/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds locator-interpretation semantics (bare = CSS, text: prefix) but says nothing about not-found behavior, whether the call blocks until the timeout, or whether it errors versus returning empty, which is the one behavioral detail an agent still needs.

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

Conciseness4/5

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

Two short sentences, front-loaded with the primary action and resource. The second sentence carries the locator-syntax rule, though it is nearly verbatim what the input schema already documents, so it earns slightly less than a full mark.

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

Completeness3/5

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

An output schema exists, so return-value explanation is not required, and annotations carry the safety semantics. What remains missing is failure behavior (no match, timeout expiry) and any hint that this is the single-element counterpart to element_find_all, which matters given the dense element_* sibling set.

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 baseline is 3. The second sentence largely restates the schema's own selector description (bare = CSS, text:..., tag:/css:/xpath:/@attr), and the description says nothing about the accessibility target object, shadow_hosts, frame_selectors, or tab_id, so it adds little beyond structured fields.

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?

States a specific verb and resource (find an element on the page) plus the accepted locator syntax, which is enough for an agent to know what it does. It does not, however, differentiate itself from the many close siblings such as element_find_all, wait_for_element, shadow_find, or frame_find, so the agent gets no routing help.

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?

There is no when-to-use or when-not-to-use guidance. The description never says to prefer this over element_find_all for a single match, over wait_for_element when the element may not yet exist, or over shadow_find/frame_find for scoped lookups. Usage is only implied by the verb 'find'.

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