Opencli Browser

Gives Claude direct control over a real Chrome window through the opencli CLI. You get selector-first targeting with automatic stale-ref recovery, structured envelopes that report match confidence, and network capture so you can skip DOM scraping when the page loads data from JSON. The skill enforces inspect-before-act discipline and compounds form metadata (date formats, full option lists) into single responses to keep token budgets sane. Use it for logged-in flows, ad-hoc extraction, or filling multi-step forms where a static adapter doesn't exist yet. The bind command lets you hand an already-open tab to the agent mid-session. Honest take: the match_level system (exact, stable, reidentified) is clever enough that you can survive light DOM churn without constantly re-querying.

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.
