Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/jackwener/opencli --skill opencli-browser- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads opencli-browser automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
Security audits
Independent scans of the skill's instructions and bundled files.
SKILL.md
The instructions your agent reads when the skill is triggered.
Browser tools for agents
Use the capability that fits the task. Discover commands with opencli list <query>;
read exact arguments with opencli browser <command> --help -f json.
Run opencli doctor when diagnosing a connection problem.
Scope and results
Page commands require --session <name>. Reuse that name across a task; different
sessions isolate page work. --profile <name> selects a Chrome profile when needed.
Options can follow command arguments:
opencli browser open https://example.com --session research
opencli browser state --session research
opencli browser click --role button --name Search --session research
opencli browser close --session research
Default output is one JSON value: { "ok": true, "data": ... }.
Failures return { "ok": false, "error": { "code": "...", "message": "...", "hint": "..." } }
and a nonzero exit code. Diagnostic logs go to stderr. network --follow and
console --follow stream one envelope per line. Help, version and shell completion
are inspection/export surfaces; structured help uses --help -f json.
Read the returned data and error fields. When error.outcome is unknown, inspect
the affected state before retrying a write.
Page targets and interaction
statereturns URL and interactive element refs.--diagnosticsalso reports page title and available initial-state globals;--source axselects the AX tree.findlocates elements. Interaction targets accept a ref, CSS selector, or semantic flags such as--role,--name,--label,--text,--testid.- Use
--nthto resolve deliberate multiple matches. On stale refs, read fresh state or locate the element again; refs describe the observed page. fillreplaces a field and verifies its value;typetypes text. Other actions includeclick,select,check,upload,drag,keysanddialog.get text|value|attributes|html,extract,screenshotandevalexpose page data.evalexecutes JavaScript in the page and can mutate state.wait xhr|selector|text|downloadobserves an expected condition. Consult help for timeouts and matching rules.tab list|new|select|closemanages session tabs.--tabaccepts the page identity returned by these commands; these are different from numeric native Chrome IDs.frameslists frame targets;eval --frameevaluates in a selected frame.
bind --session research attaches the current user tab. Bound sessions permit
navigation but block tab creation, selection and closure. unbind releases the
binding without closing the user tab. Owned sessions keep leased tabs until
close or idle expiry. --window foreground|background controls owned windows.
Network and scripts
opencli browser network --session research
opencli browser network --detail RequestKey --session research
opencli browser network --static --session research
network returns captured request keys and response shapes. --detail reads a
cached request; --filter selects shapes; --raw exposes response bodies.
--static adds Acorn AST candidates from loaded scripts, with source locations,
methods, query/body parameter names and observed request evidence. EXPR means
an unresolved expression. Static candidates are not executed or proven APIs.
Check analysisComplete, script errors, omitted scripts and networkSource.
An empty live capture can reuse a recent cache; reported provenance distinguishes it.
Native Chrome management
Native calls need no session and do not attach a page:
opencli browser chrome describe
opencli browser chrome describe tabs.group
opencli browser chrome call tabs.query '[{}]'
opencli browser chrome call tabs.group '[{"tabIds":[123,456],"createProperties":{"windowId":10}}]'
opencli browser chrome call tabGroups.update '[789,{"title":"Research","color":"blue"}]'
Use numeric IDs returned by Chrome, replacing the example IDs. describe lists
supported methods, signatures, live permissions and official documentation.
Native-created tabs/windows persist. Mutations touching active OpenCLI session
tabs or managed groups return managed_resource_conflict; ordinary groups can be
created, renamed, recolored, moved and dissolved with tabs.ungroup.
