Import cookies from your real Chromium browser into the headless browse session. (gstack).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

<!-- AUTO-GENERATED from SKILL.md.tmpl — do not edit directly -->
<!-- Regenerate: bun run gen:skill-docs -->

## Preamble (run first)

```bash
~/.claude/skills/gstack/bin/gstack-skill-start --skill "setup-browser-cookies" --model "claude"
```

Read the echoed `KEY: value` STATUS lines — they drive every preamble rule
below. **Degraded mode:** if `SKILL_START_PROTO: 1` is missing from the output
(script absent, stale install, or a different protocol number), apply safe
defaults: treat `SESSION_KIND` as `interactive`, do NOT assume Conductor,
skip onboarding/telemetry steps (their gates are marker-based, so consent and
onboarding prompts are DEFERRED to the next healthy run — never lost), tell
the user to run `./setup` or `/gstack-upgrade`, and proceed with their task.
Note `SESSION_ID` and `TEL_START` from the output — the Telemetry step needs
them at skill end.

**Instruction blocks:** the output may contain
`GSTACK_INSTRUCTION_BEGIN: <id> <session-id>` … `GSTACK_INSTRUCTION_END`
blocks — one-time onboarding and consent directives whose runtime gates fired.
Follow each before continuing, then proceed with the user's task. Honor a

How to install

The exact contents, by fingerprint
mdr add garrytan/gstack/setup-browser-cookies@sha256:27bf14c11cb646e9

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
