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

opencli 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 1mo 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.

OpenCLI: Gather Web Information Without Login

OpenCLI turns websites into CLI commands. Many adapters work against public APIs — no browser, no login, no credentials needed. This skill covers the no-login subset: 25+ built-in public adapters plus AI-powered discovery for any website.

Verified against opencli list — only adapters tagged [public] are listed below. Adapters tagged [cookie], [intercept], or [ui] require browser login and are excluded.

Before You Start

Check that opencli is installed:

opencli --version

If not installed:

npm install -g @jackwener/opencli

Requires Node.js 20+. No Chrome or browser extension needed for public commands.

Quick Reference: Public Adapters

These adapters work immediately — no login, no browser. Verified via opencli list output:

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.
