Escalation skill for blocked or hard-to-reach web access — load it when a normal browse/fetch is blocked (WAF, 403, Cloudflare, JS-only render, login-gated, or a platform a generic fetcher cannot read). Tiered router: TIER 1 insane-search (headless extraction + WAF bypass via curl_cffi TLS impersonation, yt-dlp, Jina Reader, public APIs, Playwright real-Chrome fallback); TIER 1.5 agent-reach (platform-native readers for Chinese and social platforms: Xiaohongshu, Douyin, Weibo, Bilibili, V2EX, WeChat, plus Twitter/Reddit/LinkedIn/GitHub); TIER 2 Chrome stealth (CloakBrowser stealth Chromium + agent-browser CDP for clicks, forms, screenshots, video, cookie login). Triggers: blocked site, bypass bot detection, cloudflare/WAF bypass, scrape, stealth browser, import cookies, fill form, screenshot, play youtube, xiaohongshu, douyin, weibo, bilibili, v2ex, wechat article, podcast transcript. NOT for simple searches (use web-search) or plain fetches (use webfetch).

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-organized, concise escalation router with concrete commands and a strong progressive-disclosure structure backed by real reference/script files. The main weakness is that the Tier 1 flagship command references an `engine/` module (and `waf_profiles.yaml`) that is not present in the bundle, leaving the primary tier's core invocation non-executable as written.

Suggestions

Resolve the `engine/` reference: the body states the engine 'lives inside this skill at engine/' and the flagship Tier 1 command is `python3 -m engine "..."`, but no `engine/` directory (and no `waf_profiles.yaml`) ships in the bundle — vendor the module or point the command at an installed package so the default tier runs as written.

Since Tier 1 is the default route for most blocked-URL/article requests, add a one-line fallback using the already-documented primitives (curl_cffi TLS impersonation, Jina Reader, yt-dlp) so the skill stays actionable even before `engine/` is available.

State explicitly how `engine/` is obtained (vendored vs. runtime-installed vs. added by the user) so the command is not a dead reference for whoever loads the skill.

DimensionReasoningScore

Conciseness

The body is dense and information-rich — routing diagram, When/Why-first headers, tables, and copy-paste commands — with no padding that explains concepts Claude already knows (no 'what is a WAF/TLS'). It is not the score-2 case because it does not include unnecessary explanation; tokens earn their place.

3 / 3

Actionability

Most commands are concrete and copy-paste ready (yt-dlp with real flags, curl Jina/V2EX endpoints, mcporter, the agent-browser CDP sequence, scripts/extract_cookies.py which exists), but the flagship Tier 1 command `python3 -m engine "..."` and the `waf_profiles.yaml` reference point to a module/file absent from the bundle, so the primary-tier command is incomplete/non-runnable as written. This is the score-2 'some concrete guidance but incomplete; missing key details' rather than score-3 'fully executable'.

2 / 3

Workflow Clarity

A clear tiered sequence (Phase 0 routing diagram → Tier 1 → Tier 1.5 → Tier 2) with explicit escalation checkpoints ('Tier 1/1.5 returned empty or partial -> TIER 2') and a verification note ('reload after injecting' / 'Do not inject cookies without reloading'); the anti-patterns list acts as a checklist. Not score-2 because checkpoints/feedback loops are explicit, and the destructive/batch cap does not apply to a web-access skill.

3 / 3

Progressive Disclosure

A clear overview pointing to well-signaled one-level-deep references, with a 'Reference docs' table mapping each file to when to read it; detailed engine/auth/CDP content is appropriately split into references/*.md and scripts/*.py, all of which resolve in the actual bundle. Not score-2 because structure, signaling, and navigation are all clean.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that names concrete per-tier capabilities, supplies an explicit natural-language trigger list, and disambiguates itself from web-search/webfetch with negative guidance. It answers both 'what' and 'when' comprehensively.

DimensionReasoningScore

Specificity

Lists many concrete actions per tier — 'WAF bypass via curl_cffi TLS impersonation, yt-dlp, Jina Reader', 'clicks, forms, screenshots, video, cookie login' — matching the 'lists multiple specific concrete actions' anchor; it is not the score-2 'some actions, not comprehensive'. Voice is third person ('Escalation skill for…', 'load it when…'), so no specificity penalty.

3 / 3

Completeness

Clearly answers what ('Escalation skill for blocked or hard-to-reach web access' plus a tiered router breakdown) and when (an explicit 'load it when…' clause, a Triggers list, and negative guidance 'NOT for simple searches (use web-search) or plain fetches (use webfetch)'), so it is not the score-2 'what present, when only implied'.

3 / 3

Trigger Term Quality

An explicit 'Triggers:' list gives natural user terms — 'blocked site', 'scrape', 'screenshot', 'play youtube', 'xiaohongshu', 'douyin', 'import cookies' — plus 'WAF, 403, Cloudflare, JS-only render, login-gated', giving broad coverage rather than just 'some relevant keywords'.

3 / 3

Distinctiveness Conflict Risk

It occupies a clear niche (escalation for blocked/hard-to-reach access) and actively prevents conflicts via 'NOT for simple searches (use web-search) or plain fetches (use webfetch)', matching 'clear niche with distinct triggers; unlikely to conflict'.
