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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00100 | $0.00761 |
| Opus 5 | $0.00050 | $0.00380 |
| Sonnet 5 | $0.00020 | $0.00152 |
| Haiku 4.5 | $0.00010 | $0.00076 |
Grade A, and why
obscura 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 json
Start CDP server (port 9224 to avoid Chrome conflict on 9222):
obscura serve --port 9224 --stealth
Chain 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.com
Connect 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.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 8d ago First seen · 65 lines · 100 tokens per session scan A 72f6f63a4d1f
obscura is a skill published in the GitHub repository tdimino/claude-code-minoan (41 stars, last pushed yesterday), licensed MIT. It adds 100 tokens to every session and 761 once invoked, about $0.0005 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 2026-09-03.
