# kernel-auth

Manages browser authentication via KERNEL profiles or vault credentials. It helps when an agent task genuinely requires a web UI instead of an API.

## What it does

The skill manages site logins when operations cannot proceed through dedicated APIs, MCP servers, or local data. Rather than typing credentials directly into an active session, it spins up an isolated temporary KERNEL browser. Once access is confirmed, the resulting session profile is saved for reuse.

The system requires the `kernel` binary in PATH. Without this tool, the skill cannot configure connections or check flow statuses. It links resources to projects using `KERNEL_PROJECT` or the `--project` flag, and supports vault approvals via 1Password.

Authentication runs separately from the main work session. Work pauses during reauthentication. Once confirmed, the agent launches a clean browser session backed by the authenticated profile and telemetry.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add kernel/skills --skill kernel-auth -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/kernel-auth/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/kernel-auth/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add kernel/skills --skill kernel-auth -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/kernel-auth/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add kernel/skills --skill kernel-auth -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/kernel-auth/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install kernel/skills kernel-auth
```

2. **Manually: put the files in place**
- File: `.github/skills/kernel-auth/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add kernel/skills --skill kernel-auth -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/kernel/skills --path plugins/kernel-cli/skills/kernel-auth
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/kernel-auth/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add kernel/skills --skill kernel-auth -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- provision an authenticated browser profile for protected pages
- sign into dashboards using 1Password approval without exposing secrets
- isolate login processes from the working browser session
- safely reauthenticate when web sessions expire mid-task

## Example prompts
- Log in to `app.example.com` using KERNEL managed auth and open the admin dashboard
- Access the internal portal using vault credentials with 1Password approval

# Kernel Auth

use a managed auth connection to acquire a reusable authenticated browser profile, or a vault credential to sign in from the agent's own browser, then continue the original website task with the browser-control method that fits it. this skill owns authentication and the handoff to an authenticated browser; it does not assume the task is qa.

## decide whether authentication is needed

make this decision before listing or creating managed-auth connections or vault credentials:

1. treat a url as a resource identifier, not as evidence that the task requires browser access.
2. for structured reads and writes, prefer authoritative local records or a dedicated, service-specific api, cli, mcp server, or other first-party integration when it supports the operation. search the host's tool catalog, including deferred mcp tools, before concluding that no integration is available.
3. choose a browser only when the task genuinely requires the authenticated website ui, the dedicated integration lacks the needed capability, or browser behavior itself is under test.
4. after choosing a browser, start hosted login only when the target operation requires authenticated state. public or unauthenticated pages should not trigger managed auth.

if a dedicated integration can complete the task, use it and do not continue with this skill. if the decision selects an authenticated browser path, choose managed auth or vault credentials below; authenticated browser tasks must still use one of them.

## choose managed auth or vault credentials

| | managed auth | vault credentials |
| --- | --- | --- |
| who runs the login | KERNEL, in its own temporary browser | the agent, in its current browser |
| result | a reusable authenticated profile | a signed-in task browser; save it to a profile if needed |
| recovery | health checks and eligible automatic reauthentication | the agent signs in again when needed |
| fits | unattended or recurring work on known sites | an end user who is present, or a login prompt mid-task |
```
