bxc-detect

A detection skill for finding anti-bot barriers such as Cloudflare and DataDome, and identifying web technologies such as Angular, React, and Wiz. It also recognizes blocked pages and challenge pages.

In plain words
What is it for?
Use it to inspect blocked websites, identify their framework, recognize Google-related technologies, and choose among static, fast, or stealth profiles.
Why use it?
It helps explain why a website request is being blocked and choose an appropriate browsing approach.

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

bxc-detect 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 2d 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

Skill: Bxc Block & Framework Detection (bxc-detect)

Use this skill to identify anti-bot protections (Cloudflare, DataDome) and underlying web frameworks (Wiz, Angular, React).

When to use

  • You are being blocked by a target.
  • You need to decide which profile (static, fast, stealth) to use.
  • You want to identify if a site uses Google-specific technologies.

Capabilities

  • Detects 403 blocks and challenge pages.
  • Identifies 5600+ Google domains and their internal frameworks.
  • Suggests auto-escalation paths.
Changes

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.
