kimi-webbridge

kimi-webbridge is a skill for Claude Code, Codex from mxyhi/ok-skills. It costs 127 tokens per session (3,406 once invoked), scanned B, original, Apache-2.0.

A way for an AI agent to control the user's real web browser, including pages where the user is already signed in. It can navigate, click, type, read page content, and take screenshots.

In plain words
What is it for?
Use it to automate browser tasks, fill in forms, inspect pages, interact with logged-in websites, and capture screenshots.
Why use it?
It avoids rebuilding login sessions or relying only on page data when a task requires using an actual website interactively.

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • medium Data Exfiltration · line 42
    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
  • medium Excessive Agency · line 162
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

kimi-webbridge scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Tools

Tool Args Returns Note
navigate url, newTab(bool), group_title {success, url, tabId} First call opens a tab — see Tabs. group_title sets the group's visible label
find_tab url, active(bool) {success, url, tabId, borrowed} Re-select a tab this session opened; active:true borrows the tab the user is viewing — see Tabs
snapshot {url, title, tree} with @e refs Accessibility tree (text) — use this to read page content and locate elements
click selector (@e ref or CSS) {success, tag, text} Synthetic el.click()
fill selector, value {success, tag, mode} Works on <input>/<textarea> AND [contenteditable] (ProseMirror/Lexical/Slate). mode is "value" or "contenteditable"
evaluate code (supports async/await) {type, value}
cdp method, params raw CDP response Raw chrome.debugger passthrough — what evaluate is to JS, cdp is to CDP. Low-level escape hatch for cases the tools above don't cover
screenshot format(png|jpeg), quality(0-100), optional selector (@e/CSS), optional path {format, path, sizeBytes, mimeType} Returns a file path, not base64 — see Screenshots
network cmd(start|stop|list|detail), filter, requestId request/response data
upload selector, files(string[]) {success, fileCount}
save_as_pdf paper_format, landscape, scale, print_background, optional path {path, sizeBytes, mimeType, pageTitle} Render current page → PDF, returns a file path — see Save as PDF
list_tabs {success, tabs:[{tabId, url, title, active, groupTitle}]} Inspect tabs in the current session
close_tab {success, closed: bool} Close the current tab in the session
close_session {success, closed: int} Close all tabs in the session — closed is the count. See Sessions for when to call

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
