ATTRIBUTION / NOTICE

This skill (ultimate-browsing, part of @oh-my-opencode/shared-skills) ships project-original content plus two third-party tools that it installs at runtime (it does NOT vendor their source). Each runtime tool's license and required notices are reproduced below.

1. Project-original content (no third-party source vendored)

The following are authored by the oh-my-openagent project and carry no third-party license obligation:

engine/** — the insane-search Tier-1 fetch engine (curl_cffi grid, WAF detection, Playwright fallback templates, bias_check.py no-site-name gate).
references/insane-search/** and references/agent-reach/** — the Tier-1 and Tier-1.5 reference docs.
scripts/extract_cookies.py, scripts/cookie_paths.py, scripts/cookie_crypto.py and their tests — the cross-platform cookie module.
SKILL.md, references/chrome-stealth.md.

These reference platform-native CLIs and public APIs by name (e.g. xhs, yt-dlp, agent-reach, mcporter, Jina Reader, V2EX public API). Those are external tools the user installs separately; this skill includes none of their source.

2. CloakBrowser (CloakHQ) — Tier-2 stealth Chromium (runtime dependency)

The Tier-2 stealth browser is CloakBrowser, installed at runtime via pip (pip install cloakbrowser). No CloakBrowser source is vendored in this repository.

Source: https://github.com/CloakHQ/CloakBrowser
Pinned runtime version: 0.4.0 (documented in references/chrome-stealth.md; this is a documented version string, not an automated drift check).
Wrapper source license: MIT License.
Binary license: the compiled CloakBrowser Chromium binary downloaded by cloakbrowser.ensure_binary() is governed by the separate CloakBrowser Binary License: https://github.com/CloakHQ/CloakBrowser/blob/main/BINARY-LICENSE.md
Redistribution note: this npm package does not redistribute the CloakBrowser binary, does not repackage it, and does not include it in skills/ or dist/skills. Users who run the Tier-2 setup download the binary directly from CloakHQ's official distribution channels and must comply with that binary license.

3. agent-browser (vercel-labs) — Tier-2 CDP automation CLI (runtime dependency)

The Tier-2 automation CLI is agent-browser, installed at runtime via npm (npm i -g agent-browser). No agent-browser source is vendored in this repository.

Source: https://github.com/vercel-labs/agent-browser
Pinned runtime version: 0.29.1 (documented in references/chrome-stealth.md; documented version string, no automated drift check).

Changes (Apache-2.0 §4(b)): none. agent-browser is installed unmodified at runtime; no agent-browser source file is copied, modified, or redistributed by this skill. This skill only documents how to invoke the upstream CLI.
NOTICE: the upstream agent-browser distribution may include a NOTICE file. As this skill redistributes no agent-browser source, no upstream NOTICE content is bundled here; consult the upstream repository for its NOTICE file when present.
