preamble-tier: 1
version: 1.0.0
description: |
Import cookies from your real Chromium browser into the headless browse session.
Opens an interactive picker UI where you select which cookie domains to import.
Use before QA testing authenticated pages. Use when asked to "import cookies",
"login to the site", or "authenticate the browser". (gstack)
triggers:
- import browser cookies
- login to test site
- setup authenticated session
allowed-tools:
- Bash
- Read
- AskUserQuestion

{{PREAMBLE}}
# Setup Browser Cookies
## 1. Choose the browser
Use this checkout as the gstack root if it contains `BROWSER.md` and `browse/SKILL.md`; otherwise use the installed root containing `bin/gstack-skill-start`, never a generated host stub. Read that root's `browse/SKILL.md` **BROWSER SETUP** section and run its probe first. On `READY`, stop importing: use Aside's sessions or ask the user to sign in there. Otherwise follow the probe's fallback handling, then continue below.
{{BROWSE_SETUP}}
```bash
$B status
```
If status says `Mode: cdp`, stop: the real browser already has sessions.
## 2. Confirm options before import
Open the known target and keep its tab unchanged. Both options default off and require explicit request:
- **`--verify-auth` / picker checkbox:** reloads the target. Have the user privately configure daemon `GSTACK_COOKIE_AUTH_SELECTOR` and `GSTACK_COOKIE_AUTH_EXPECTED_IDENTITY` **before startup**. Never invent values or assume CLI env reconfigures an existing daemon. Missing config rejects before mutation. Require a successful same-origin response and exactly one visible element whose whitespace-normalized text exactly matches the expected identity.
- **`--clear-storage`:** for suspected stale storage, obtain explicit approval. Chromium only: clears captured-origin localStorage (shared across same-origin context tabs) and target-tab sessionStorage. Other origins, other tabs' sessionStorage, IndexedDB, and service workers stay intact. It uses an isolated world/native deadline; other engines reject reset, not imports/auth checks. Never auto-approve or claim rollback after partial failure.
## 3. Select source and scope
```bash
$B cookie-import-browser
```
Ask the user to choose browser, account/profile, and domains, then say when done. Never guess accounts or treat default Comet as consent. Unreadable profiles are unknown, not empty. Rerun for an expired five-minute one-use link.
Direct import: pass the chosen browser and `--domain` after navigating to a matching target. `--profile` takes a directory, not a display name; omit only for an unambiguous relevant profile, otherwise use the picker. `--all` requires consent for all non-expired profile cookies; it cannot accompany `--domain` or `--clear-storage`.
Read that same root's `BROWSER.md`, **Choosing a source and checking sign-in**, for examples, profile labels, supported sources and platform setup.
## 4. Report honestly
Report receipt/picker counts, partial/zero/error and reset outcomes, not raw `$B cookies`. Imports affect the context, not one tab. **Not checked** means no requested check; **not verified** means it failed; **verified** requires positive target evidence. Zero imports, counts, or HTTP 200 never prove login.
Never request/publish cookie values, passwords, identity/profile text, session details, or raw errors in public logs.
## Platform boundaries
Dia is macOS-only. Keychain approval is the user's choice. Database retries are bounded; permission denial needs user action, not repeated prompts.
Windows supports DPAPI-compatible cookies, not all App-Bound Encryption; native extraction stays disabled pending qualification. Closing Chrome cannot bypass Chrome 136+ default-directory protection, including numbered profiles. No TCP fallback or real-profile copies. Offer headed manual sign-in only with a display available.
