harn cookies

harn cookies [--store <path>] <subcommand> [options]

Manages the shared browser cookie store at ~/.cache/harnery/cookies.json. The format is CDP-native, so the same jar is read and written by harn browse, harn browse-ai, and harn fetch, and it round-trips cleanly with Playwright and agent-browser. Use it to inspect what’s stored, set a cookie by hand, produce a Cookie: header for another tool, or move a jar between tools.

Running harn cookies with no subcommand lists the store (same as harn cookies list). Use --store <path> for a separate jar (e.g. one per environment); it goes before the subcommand.

harn cookies list [--domain <d>] [--json] # list cookies, grouped by domain
harn cookies set <name> <value> --domain <d> # set a cookie (creates the file if missing)
harn cookies clear (--domain <d> | --all) # remove matching cookies, or wipe everything
harn cookies header <url> # print a Cookie: header value for the URL
harn cookies import <file> [--replace] # merge cookies from a JSON file
harn cookies export <file> # write the store to a file
harn cookies info [--json] # store path, size, counts, exporting tool
  • list--domain <domain> filters to one domain; --json for machine output.
  • set--domain <domain> is required (e.g. .example.com). Also --path <path> (default /), --secure, --httpOnly, --sameSite <Strict|Lax|None>, --expires <unix-seconds> (omit for a session cookie).
  • clear — one of --domain <domain> (drop cookies for a single domain) or --all (wipe cookies + origins) is required.
  • import--replace replaces the entire store instead of merging by (name, domain, path).
