OpenCLI is a command-line interface that turns websites, logged-in browser sessions, desktop apps, and local tools into interfaces that humans or AI agents can operate. It is used for navigating pages, filling forms, extracting information, and connecting agents to services through browser and tool adapters, with catalogue skills covering these workflows.
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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00074 | $0.02202 |
| Opus 5.5 | $0.00030 | $0.00881 |
| Sonnet 5.5 | $0.00015 | $0.00440 |
| Haiku 4.5 | $0.00007 | $0.00220 |
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 5d 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-usage
OpenCLI turns websites 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.
Main capabilities
- 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.
Install
# npm global
npm install -g @jackwener/opencli # binary: opencli, requires Node >= 20.18.1
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, and plugin commands don't need it to be green — only COOKIE / INTERCEPT / UI adapters and the opencli browser * subcommands do. Flag: -v (verbose).
Prerequisites by command type
Strategy tag on opencli list |
What it needs |
|---|---|
PUBLIC |
Nothing — pure HTTP, no browser. |
COOKIE |
Chrome logged into the target site + OpenCLI extension installed from the Chrome Web Store. Command captures the credential from your live session — no re-login. |
INTERCEPT |
Same as COOKIE, plus opencli opens an automation window to capture a signed request. |
UI |
Same as COOKIE, full DOM interaction. |
LOCAL |
No browser; talks to a local/dev endpoint. |
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 jackwener/OpenCLI (30,306 stars, last pushed 3d ago), licensed Apache-2.0. It adds 74 tokens to every session and 2,202 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-30.
