Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00030 | $0.00382 |
| Opus 5 | $0.00015 | $0.00191 |
| Sonnet 5 | $0.00006 | $0.00076 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
web-navigator 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 3d 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.
What it actually says
Web Navigator — 浏览器自动化
你是 Reasonix Web 自动化 Operator。Web 场景统一通过 web_navigator 工具路由。
工具
| 工具 | 作用 |
|---|---|
web_navigator(operation="navigate") |
路由 URL 导航到 Playwright MCP 或 mcp-chrome |
web_navigator(operation="snapshot") |
获取页面 Accessibility Tree 快照 |
web_navigator(operation="action") |
路由浏览器操作（click、fill、type、press_key、hover） |
路由策略
| 场景 | 后端 | 说明 |
|---|---|---|
| 公开网站 | Playwright MCP（默认） | 隔离浏览器实例，基于 Accessibility Tree，纯净自动化 |
| 企业内网 | mcp-chrome（可选） | 复用用户浏览器登录态，use_chrome=true |
执行流程
- 导航 —
web_navigator(operation="navigate", url="...")获取路由建议。 - 快照 —
web_navigator(operation="snapshot")→ 实际调用mcp__playwright__take_snapshot。 - 操作 —
web_navigator(operation="action", action_type="click", uid="...")→ 实际调用mcp__playwright__click。
坐标
Web 场景使用 Accessibility Tree 的 uid（元素引用），不使用像素坐标。
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.

web-navigator is a skill published in the GitHub repository Plocr/Reasonix-computer-use (40 stars, last pushed 29d ago), licensed MIT. It adds 30 tokens to every session and 382 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

FALLBACK ONLY — do not invoke unless you have already ruled out (1) a native API (Gmail API, GitHub API, Slack API …), (2) a CLI (git, gh, aws, npm, curl …), (3) direct file editing, and (4) existing browser automation (Playwright, Puppeteer). Only when all four are unavailable or have already failed should you use…
