Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

plastic-uninstall scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

plastic-uninstall is a skill published in the GitHub repository zalom/plastic (10 stars, last pushed 3d ago), licensed MIT. It adds 60 tokens to every session and 713 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (reads agent configuration directories, enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
