# Uninstall Plastic

The installer tracks every file it writes in a manifest, so uninstall is exact and
leaves no orphans. Prefer running it through the CLI; this skill wraps the same
underlying uninstaller and adds reporting + verification.

## Channel rule

If Plastic is installed, derive `<channel>` from `~/.plastic/VERSION`: a version containing
`-alpha` means `@alpha`, `-beta` means `@beta`, otherwise `@latest`. If not installed,
default to `@latest`. The user can always override with `--alpha` / `--beta` / `--latest`.

## Procedure

### Step 1: Run the uninstaller

```bash
npx -y @zalom/plastic@<channel> uninstall --claude
```

(Use `--codex` / `--hermes` / `--all` to target other agents. `bunx -y @zalom/plastic@<channel> uninstall --claude` works too.)

This removes, for the targeted agent:
- all `~/.claude/skills/plastic-*/` skills
- all `~/.claude/hooks/plastic-*` hooks (and restores any saved original statusline)
- the `~/.claude/plastic/` state dir + manifest
- any **legacy** plugin layout: `plugins/marketplaces/plastic`, `plugins/cache/plastic`,
  the old nested `skills/plastic/`, and the `plastic@plastic` /
  `extraKnownMarketplaces.plastic` / `known_marketplaces.json` registrations

### Step 2: Report removed vs left

Relay the uninstaller's output to the user: what was **removed** and what was
**left in place**.
- **Left:** `~/.plastic/` (intent store, history, projects) and any non-Plastic
  settings.json entries.

### Step 3: Verify removal

Tell the user to confirm:

```bash
ls ~/.claude/skills | grep '^plastic-'    # -> no output
ls ~/.claude/hooks  | grep '^plastic-'    # -> no output
grep -n plastic ~/.claude/settings.json   # -> no plastic hook/plugin refs
```

### Step 4: Report

Emit the reporting block, using the Step 3 checks for the verification line:

```
Plastic uninstall (<channel>)
Command:  npx -y @zalom/plastic@<channel> uninstall --claude <flags>
Version:  removed
Verification: <Step 3 results, or "clean">
```

Then:

```
Plastic is uninstalled from [agent].
Your intent store at ~/.plastic/ is untouched.
```

Uninstall removes installed harness files only. The store at `~/.plastic/` (intents,
history, projects, config, version ledger) always stays; no uninstall path deletes it.
Tell the user: "Your data is at ~/.plastic/. Re-install anytime with
`npx -y @zalom/plastic@latest install --claude` (or your channel)."
