How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
3 rules. About 0 are common, 1 is distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 35
Start CDP server (port 9224 to avoid Chrome conflict on 9222):
- Very specific: line 55
--proxyis a global flag: Place it before fetch/serve/scrape, not after. - Very specific: line 56
--quietsuppresses the banner: Use it when piping output.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Obscura
Rust headless browser with built-in anti-fingerprinting and CDP server. Fills the gap between Lightpanda (CDP, no stealth) and Scrapling (stealth, no CDP). Binary at ~/tools/obscura/obscura.
When to Use
| Scenario | Tool |
| Clean single-page markdown | Firecrawl |
| Cloudflare Turnstile bypass | Scrapling |
| Lightpanda / Scrapling | |
| Twitter/X | Jina |
Interactive @ref automation | agent-browser |
| Stealth CDP automation | Obscura |
| Batch stealth scraping | Obscura |
| Low-RAM headless (30MB) | Obscura |
Usage
Fetch a page with stealth:
obscura fetch --stealth --quiet https://example.com --eval "document.title"Parallel batch scrape:
obscura scrape URL1 URL2 URL3 --concurrency 25 --format jsonStart CDP server (port 9224 to avoid Chrome conflict on 9222):
obscura serve --port 9224 --stealthChain through Proxelar for defense-in-depth — --proxy is a global flag, goes before the subcommand:
obscura --proxy http://127.0.0.1:8080 serve --port 9224 --stealth
obscura --proxy http://127.0.0.1:8080 fetch --stealth https://example.comConnect Puppeteer: browserWSEndpoint: "ws://127.0.0.1:9224/devtools/browser"
Connect Playwright: endpointURL: "ws://127.0.0.1:9224"
CDP domain coverage: see references/cdp-coverage.md. Includes non-standard LP.getMarkdown for DOM-to-Markdown.
Gotchas
- Port 9224 is convention, not default. The binary defaults to 9222 (Chrome's port). Always pass
--port 9224. --stealthis off by default. Pass it explicitly for anti-fingerprinting and tracker blocking.--proxyis a global flag. Place it beforefetch/serve/scrape, not after.--quietsuppresses the banner. Use it when piping output.- WebSocket path differs from Lightpanda. Obscura:
/devtools/browser. Lightpanda: bare endpoint. - Ad-hoc signed binary, no notarization. SHA-256 recorded at
~/tools/obscura/obscura.sha256. Verify on update.
Helper Scripts
