Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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-setup-marketplace-auto-notification 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 1mo 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.

Setup Marketplace Auto Notification

Overview

Configures the plugin side of the auto-notify chain: plugin push → notify workflow → repository_dispatch → marketplace receiver → marketplace.json bump → Claude Code sees the new version on next refresh. Works for any plugin/marketplace pair with placeholder substitution only.

Prerequisites

  • gh auth status green for the owner of BOTH repos
  • PAT with repo scope (or fine grained RW) — see pat-secret-setup.md
  • Marketplace has a repository_dispatch: plugin-updated receiver (create from receiver-workflow-template.md)
  • Plugin has a valid .claude-plugin/plugin.json with name + version

Instructions

  1. Check env for MARKETPLACE_PAT first (length only — never print the value). If unset, walk the user through creating one and exporting it.
  2. Set the secret via scripts/set_marketplace_pat.py — never improvise gh secret set. Full rules and the forbidden-patterns list in pat-secret-setup.md. 
    uv run python scripts/set_marketplace_pat.py <plugin> <marketplace>
uv run python scripts/set_marketplace_pat.py --verify-only <plugin> <marketplace>
  3. Install notify-marketplace.yml on the plugin repo from the template.
  4. Verify the marketplace receiver exists on its default branch — create it from receiver-workflow-template.md if missing.
  5. Dry-run the chain without cutting a real release.
  6. Verify end-to-end: plugin run → marketplace run → marketplace.json bumped → Claude Code refresh sees the new version.

Copy this checklist and track your progress:

  • Check env for MARKETPLACE_PAT
  • If absent, create PAT and export it
  • Run scripts/set_marketplace_pat.py (NEVER improvise gh secret set)
  • Verify secret exists via --verify-only
  • Scaffold notify-marketplace.yml
  • Verify marketplace receiver exists
  • Dry-run end-to-end

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.
