name	plastic-uninstall
description	Use when the user wants to remove Plastic from an agent. Runs the manifest-driven uninstaller (removes skills, hooks, statusline, and any legacy plugin layout), reports exactly what was removed and what was left behind, then gives verification steps. Optionally deletes the intent store.

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

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:

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 + offer the data decision

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.

Delete it too?
  a) Keep everything (recommended): re-install anytime with npx
  b) Delete everything now: removes ~/.plastic/ entirely (irreversible)

• Keep: "Your data is at ~/.plastic/. Re-install anytime with npx -y @zalom/plastic@latest install --claude (or your channel)."
• Delete: run rm -rf ~/.plastic/ and confirm.
