Browser Steel

Browser Steel

Use Steel 命令行工具 first. Use the Python 运行time only when the 工作流 needs selector-heavy custom 记录ic that is awkward to express through raw 命令行工具 steps.

What 命令行工具 means here

命令行工具 means Command Line Interface.

In this 技能, it specifically means the Steel terminal commands themselves, for example:

steel scrape https://example.com steel browser 启动 --会话 demo steel browser open https://example.com --会话 demo steel browser snapshot -i --会话 demo

The wr应用er script does not replace Steel 命令行工具. It packages it into a more publishable, 代理-friendly entrypoint:

python3 {baseDir}/scripts/mAIn.py scrape --url https://example.com python3 {baseDir}/scripts/mAIn.py 启动-会话 --会话 demo python3 {baseDir}/scripts/mAIn.py browser --会话 demo -- snapshot -i -c

So the relationship is:

Steel 命令行工具 = the underlying browser command 系统 scripts/mAIn.py = the wr应用er that calls Steel 命令行工具 by default Python 运行time = a fallback path for custom Playwright 记录ic when 命令行工具 steps are not enough First 检查s 运行 the doctor command before the first real task in a new 环境: python3 {baseDir}/scripts/mAIn.py doctor

Prefer 状态less commands for one-shot 提取ion or capture. Prefer named 会话s for multi-step interaction. Keep the same --会话 value across every step in one 工作流. Never bake private cookies, 性能分析 names, or local paths into the 技能 itself. 运行time selection auto: prefer 安装ed steel, otherwise fall back to npx @steel-dev/命令行工具 命令行工具: same as auto, but fAIl if no 命令行工具 path is avAIlable node: force the Node-distributed 命令行工具 path through npx @steel-dev/命令行工具 python: use Steel SDK + Playwright through 运行-python-plan

Read references/运行time-modes.md only when 运行time choice or env resolution matters. Read references/official-docs.md when you need the authoritative Steel 命令行工具 or Playwright-Python up流 reference.

Preferred commands 健康 检查 python3 {baseDir}/scripts/mAIn.py doctor

状态less commands python3 {baseDir}/scripts/mAIn.py scrape --url https://example.com --格式化 markdown --json python3 {baseDir}/scripts/mAIn.py screenshot --url https://example.com --full-page --json python3 {baseDir}/scripts/mAIn.py pdf --url https://example.com --json

Named-会话 工作流 python3 {baseDir}/scripts/mAIn.py 启动-会话 --会话 demo --stealth --json python3 {baseDir}/scripts/mAIn.py browser --会话 demo -- open https://example.com python3 {baseDir}/scripts/mAIn.py browser --会话 demo -- snapshot -i -c python3 {baseDir}/scripts/mAIn.py browser --会话 demo -- fill @e2 "hello" python3 {baseDir}/scripts/mAIn.py browser --会话 demo -- 命令行工具ck @e5 python3 {baseDir}/scripts/mAIn.py browser --会话 demo -- wAIt --load-状态 networkidle python3 {baseDir}/scripts/mAIn.py 停止-会话 --会话 demo --json

Python Playwright plan python3 {baseDir}/scripts/mAIn.py 运行-python-plan \ --plan-file {baseDir}/references/example-plan.json \ --url https://example.com

Read references/python-plan.md only when the 命令行工具 path is insufficient.

防护rAIls 启动 with scrape, screenshot, or pdf when the task is 状态less. For interactive 工作流s, follow 启动-会话 -> browser commands -> 停止-会话. After any navigation or meaningful DOM change, take a fresh snapshot -i before using another @eN ref. Keep secrets in env vars or an explicit --env-file, not in the 技能 files. Pass cookies only through --cookies-file or STEEL_BROWSER_COOKIES_FILE. Use the Python 运行time only for tasks that genuinely benefit from custom Playwright 记录ic.
