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 | $0.00080 | $0.07341 |
| Opus 5 | $0.00040 | $0.03671 |
| Sonnet 5 | $0.00016 | $0.01468 |
| Haiku 4.5 | $0.00008 | $0.00734 |
Grade A, and why
opencli-browser 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 2d 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 — 445 lines — stays where its author put it; the contents beside it link to each section on GitHub.
opencli-browser
The first reader of this CLI is an agent, not a human. Every subcommand returns a structured envelope that tells you exactly what matched, how confident the match is, and what to do if it didn't. Lean on those envelopes — do not guess.
This skill is for driving a live browser to accomplish an agent task. If you are building a reusable adapter under ~/.opencli/clis/<site>/ use opencli-adapter-author instead.
Prerequisites
opencli doctor
Until doctor is green, nothing else will work. Typical failures: Chrome not running, extension not installed, debug port blocked by 1Password / other extensions. The doctor output tells you which.
Session lifecycle
opencli browser *commands require a<session>positional immediately afterbrowser. Use the same session name for a multi-step flow; use a different name to isolate parallel browser work.- Use a stable session name for any multi-command or human-paced browser workflow. Example:
opencli browser fb-yaya-warmup open https://example.com, then reuseopencli browser fb-yaya-warmup state,extract,click, etc. - Owned browser sessions keep a tab lease alive between calls. Release it with
opencli browser <session> closeor let the idle timeout expire. opencli browser <session> bindbinds the Chrome tab you already have open to that session. Use this for logged-in pages, SSO flows, or pages you manually positioned before handing control to the agent.--window foreground|background(orOPENCLI_WINDOW=foreground|background) chooses whether OpenCLI creates/focuses a foreground browser window or uses a background browser window for owned sessions.
Bind Tab
opencli browser gmail bind
opencli browser gmail state
opencli browser gmail click "Search"
opencli browser gmail network
opencli browser gmail unbind
Binding never owns the user window and never closes the user tab. It fails closed if the tab is closed or becomes non-debuggable. Re-run opencli browser <session> bind when you switch to a different real tab.
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-browser is a skill published in the GitHub repository jackwener/OpenCLI (28,734 stars, last pushed 2d ago), licensed Apache-2.0. It adds 80 tokens to every session and 7,341 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings.
