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 A, and why

cpv-plugin-management scanned grade A with 0 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 26d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Plugin Management

Overview

Scripts at ${CLAUDE_PLUGIN_ROOT}/scripts/ for the full plugin lifecycle.

Prerequisites

  • uv and git on PATH
  • CPV plugin installed
  • gh CLI (for remote/GitHub operations)

Instructions

  1. Install: uv run "${CLAUDE_PLUGIN_ROOT}/scripts/manage_plugin.py" ./plugin/ my-mkt
  2. Update: uv run "${CLAUDE_PLUGIN_ROOT}/scripts/manage_plugin.py" --update ./plugin-v2/ my-mkt
  3. Uninstall: uv run "${CLAUDE_PLUGIN_ROOT}/scripts/manage_plugin.py" --uninstall name@mkt
  4. Enable/Disable: uv run "${CLAUDE_PLUGIN_ROOT}/scripts/manage_plugin.py" --enable <plugin> [--scope local]
  5. Validate (launcher is the portable form — mandatory from the plugin cache; direct validate_plugin.py works only from a CPV dev checkout): uv run --with pyyaml python "${CLAUDE_PLUGIN_ROOT}/scripts/remote_validation.py" plugin ./plugin/
  6. List/Search (via launcher): uv run --with pyyaml python "${CLAUDE_PLUGIN_ROOT}/scripts/remote_validation.py" registry --list or --search <query>
  7. Doctor (via launcher; or direct for --install-scanners): uv run --with pyyaml python "${CLAUDE_PLUGIN_ROOT}/scripts/remote_validation.py" doctor [--verbose] [--fix] — for --install-scanners (installs all 5 external security scanners + fclones), use uv run python "${CLAUDE_PLUGIN_ROOT}/scripts/manage_doctor.py" --install-scanners
  8. Bump version: uv run "${CLAUDE_PLUGIN_ROOT}/scripts/bump_version.py" --patch|--minor|--major

Smart plugin name resolution — accepts: plugin-name, plugin-name@marketplace, plugin-name@owner/marketplace.

Run /reload-plugins after install/update/uninstall/enable/disable done from the command line (the scripts or claude plugin …). An install, enable or disable made in the interactive /plugin menu takes effect when the menu closes and needs no reload (Claude Code v2.1.268+).

Copy this checklist and track your progress:

  • Plugin installed/updated
  • Validation passed
  • Plugin enabled (user or local scope)
  • /reload-plugins executed

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
