quicker-browser-script

quicker-browser-script is a skill for Claude Code, Codex from QuickerHub/quicker-rpc. It costs 68 tokens per session (1,052 once invoked), scanned A, original, MIT.

A workflow for writing scripts that run inside the user's browser through the Quicker browser extension, then saving those scripts as reusable actions with automatic triggers.

In plain words
What is it for?
Use it to read or change web pages, automate work in logged-in browser tabs, save the script as a Quicker action, and run it when URLs or other browser events change.
Why use it?
It lets you test browser automation on a live page before turning it into a repeatable action that runs when a chosen browser event occurs.

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 A, and why

quicker-browser-script scanned grade A with 0 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 4d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

quicker-browser-script

Pipeline: prototype script live → save as action → wire a trigger so the script runs automatically on matching pages/events.

Requires the Quicker browser extension (Quicker Connector) connected; uses the user's logged-in browser.

P1 — Prototype the script live

  1. user_browser({ action: "tabs" }) — confirm extension connected; pick tabId
  2. user_browser({ action: "run", operation: "RunScript", parameters: { tabId, script } }) — script runs in page context; return a JSON-serializable value as the result
  3. Iterate until output is correct; reuse sessionId, tabId is auto-carried when omitted
  4. Other operations (OpenUrl, GetTabInfo, GetElementInfo, …): schema via qkrpc_step_runner_get key=sys:chromecontrol + controlField = operation

CLI / MCP equivalents: qkrpc chrome tabs|run / qkrpc_chrome_tabs / qkrpc_chrome_control.

P2 — Save as a Quicker action

  1. qkrpc_action_create → edit body with workspace_program (authoring-workflow P1–P7)
  2. Steps use sys:chromecontrolalways qkrpc_step_runner_get key=sys:chromecontrol --control-field RunScript first; never guess inputParams
  3. Full module doc: docs({ action: "get", topic: "chromecontrol-authoring" }); patch with reference: "examples/chromecontrol"
  4. Verify with qkrpc_action_debug (step outputs), not plain run

P3 — Trigger setup (auto-run)

Full workflow: docs({ action: "get", topic: "trigger-workflow" }) (Tr0–Tr5). Summary:

  1. quicker_trigger({ action: "events" }) — get exact eventType, fields[].key / helpText, and variables[].key. Always before add/update.
  2. Add the rule:
quicker_trigger({
  action: "add",
  eventType: "BrowserUrlChanged",
  params: { UrlPattern: "https://github.com" },
  actionIdOrName: "<action guid>",
  note: "run page script on GitHub",
})

UrlPattern is a URL-prefix match (semicolon-separated for multiple); use a regex: prefix for regular expressions — not bare regex.

  1. Manage: list (query keyword) / update / enable / disable; delete only on explicit user ask.
  2. Optional: filter ($= bool on variables); delayMs to wait before running.
