Takes a project from no sandbox to running an AI agent inside the aicontainer devcontainer, wired for that project's stack.

## What it does

The skill inspects the stack, checks whether a Linux devcontainer fits at all, drafts a customization plan and applies it once you approve. Everything runs from the host. If `/etc/aic` is present, or `REMOTE_CONTAINERS`, `DEVCONTAINER` or `AIC_TOOLS` are set, you are already inside the sandbox and writes to `.devcontainer/` are blocked by a PreToolUse hook; the skill stops there and tells you to run setup from a host terminal.

Customization belongs in project-owned files only: `Dockerfile.project`, `docker-compose.override.yml`, `chown-paths`, `post-create.project.sh`, `vscode-extensions`, `firewall-allowlist`, `shell-rc.zsh`, `statusline.{sh,mjs,js,py}`. Leave `devcontainer.json` and `docker-compose.yml` alone — `aic init` writes them and `aic sync` overwrites them, keeping only the `AIC_TOOLS` and `AIC_SHELL` choices. Building is `aic rebuild`, not `aic up`: the managed Compose sets `pull_policy: missing`, so a cached image tag gets reused and your `Dockerfile.project` never runs.

Add a `Dockerfile.project` or an extra mount and `aic validate`, `up` and `rebuild` fail closed until the human runs `aic trust`. That command needs a TTY, so the agent's Bash tool cannot run it, and `--allow-unsafe` is not a way around it. Trust binds to an exact config hash, so editing `docker-compose.override.yml` or `Dockerfile.project` afterwards revokes it — finish the config before asking.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add stefanoginella/aicontainer --skill setup -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add stefanoginella/aicontainer --skill setup -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add stefanoginella/aicontainer --skill setup -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install stefanoginella/aicontainer setup
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add stefanoginella/aicontainer --skill setup -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/stefanoginella/aicontainer --path tools/claude-plugin/skills/setup
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add stefanoginella/aicontainer --skill setup -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/stefanoginella/aicontainer/tree/HEAD/tools/claude-plugin/skills/setup/SKILL.md

## When to use it
- detect the stack and decide whether a Linux devcontainer fits it
- draft a sandbox customization plan for a Python repo or a Postgres app
- carry tool settings, aliases and statusline into the new environment
- work out why baked tools vanished after `aic up`
- get through `aic trust` after editing `Dockerfile.project`

## Example prompts
- Set up aicontainer in this project
- Check that we're on the host and propose a customization plan for my stack
- Update the existing aicontainer setup for a new stack

# Set up aicontainer in a project

Your job is to take a project from "no sandbox" to "the AI agent runs behind the
aicontainer devcontainer boundary, configured for *this* project's stack." You
detect the stack, sanity-check that a Linux devcontainer is even the right tool,
propose a concrete customization plan, and — once the user approves — apply it.

aicontainer's whole point is letting Claude Code / Codex / OpenCode run with
permissions skipped *without* handing a prompt-injected dependency your real
`$HOME`, `.env`, SSH keys, or `gh` token. Good setup is what makes that sandbox
actually usable for the project — a Python repo needs a writable `.venv`, an
agent that uses go-to-definition needs a language server on `PATH`, a Postgres
app needs the DB reachable. That per-project wiring is the work here.

The other half is the *person*: their tool settings, prompt, aliases, and
statusline. Some of that is seeded automatically, some is deliberately dropped,
and some needs an explicit opt-in they'd never guess at. Step 6 walks them
through it — a sandbox the user can't stand working in doesn't get used.

## Golden rules (read first — they shape everything below)

These come straight from how aicontainer is designed; violating them creates work
that silently gets wiped or breaks `aic sync`.

- **Run `aic` from the host, never from inside the container.** Setup happens
  before (or outside) the sandbox. If you detect you're *inside* an aicontainer
  already (see Step 0), stop and tell the user to run this from a host terminal —
  `.devcontainer/` is mounted read-only in the sandbox by design.
- **Never hand-edit `.devcontainer/devcontainer.json` or
  `.devcontainer/docker-compose.yml`.** They are template-managed: `aic init`
  writes them and `aic sync` overwrites them (only the `AIC_TOOLS` / `AIC_SHELL`
  choices survive). All per-project customization goes in the **project-owned**
  files instead (listed in the next rule). Edits to the managed files get reset on the
  next sync.
- **All customization lives in project-owned files** that `aic sync` never
  touches: `Dockerfile.project`, `docker-compose.override.yml`, `chown-paths`,
```
