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.

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 | $0.00074 | $0.02590 |
| Opus 5 | $0.00037 | $0.01295 |
| Sonnet 5 | $0.00015 | $0.00518 |
| Haiku 4.5 | $0.00007 | $0.00259 |
Grade A, and why
opencli-usage 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 6d 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.
This is a copy
100% identical to opencli-usage — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

opencli-usage
OpenCLI turns any website, Electron desktop app, or external CLI into a uniform opencli <site> <command> surface that agents can drive without screen-scraping. This skill is the orientation layer — once you know what you want to do, load one of the specialized skills below.
The three pillars
- Adapter commands —
opencli <site> <command> [...]. Built-in adapters live inclis/, user adapters in~/.opencli/clis/. Each is backed by a strategy (PUBLIC | COOKIE | INTERCEPT | UI | LOCAL) that tells you whether a Chrome session is needed. - Browser driving —
opencli browser *subcommands (open,state,click,type,select,find,extract,network, …) for ad-hoc interaction and scraping when no adapter covers the task. Seeopencli-browser. - Current-tab binding —
opencli browser <session> bindattaches the Chrome tab the user already opened/logged into to that browser session. Follow-up commands useopencli browser <session> .... Seeopencli-browserbefore using it; bound sessions still block tab mutation. - External CLI passthrough —
opencli gh,opencli docker,opencli vercel, etc. Managed viaopencli external install <name>(auto-install fromexternal-clis.yaml) oropencli external register <name>(bring your own).
Install
# npm global
npm install -g @jackwener/opencli # binary: opencli, requires Node >= 21
opencli doctor # run before browser-dependent work (see below)
# From source
git clone [email protected]:jackwener/OpenCLI.git
cd OpenCLI && npm install
npx tsx src/main.ts <command> # same surface, no global install
opencli doctor prints a structured DoctorReport — daemon status, extension connection, version checks, and a live browser connectivity probe. Scope is narrow: it diagnoses the browser bridge (daemon + extension + Chrome wiring). PUBLIC / LOCAL adapters, opencli list, validate, verify, plugin commands, and external-CLI passthrough don't need it to be green — only COOKIE / INTERCEPT / UI adapters and the opencli browser * subcommands do. Flag: -v (verbose).
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.

opencli-usage is a skill published in the GitHub repository mxyhi/ok-skills (481 stars, last pushed yesterday), licensed Apache-2.0. It adds 74 tokens to every session and 2,590 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to opencli-usage, differing in 0 lines, and is treated as a copy.
