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.

Model	Per session	Once invoked
Fable 5.1	$0.00039	$0.01119
Opus 5	$0.00019	$0.00560
Sonnet 5	$0.00008	$0.00224
Haiku 4.5	$0.00004	$0.00112

Security

Grade A, and why

cpv-setup-github-marketplace 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 5d 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 GitHub Marketplace

Overview

Automates creation of a GitHub-hosted Claude Code plugin marketplace. Handles CI/CD setup, batch plugin linking, and cross-marketplace migration.

Marketplace layout

Three layouts: A (hub-and-spoke, separate repos), B (nested monorepo, subdirs), C (marketplace-in-plugin, single repo with both manifests, source="./"). Suggest A for multi-plugin sets, C for single-plugin repos. Details: marketplace-layouts.md.

Prerequisites

GitHub CLI (gh) authenticated with repo, workflow, admin:repo_hook scopes
CPV validator installed for pre-push validation hooks

Instructions

Create the marketplace repo and initialize marketplace.json
Install CI/CD workflow templates and sync scripts
Link plugins by fetching metadata and installing notification workflows
Validate with uvx --from git+https://github.com/Emasoft/claude-plugins-validation --with pyyaml cpv-remote-validate marketplace . --strict (remote CPV — no vendoring, no drift)

Copy this checklist and track your progress:

Create marketplace repo
Install CI/CD workflows
Link plugins
Run validation

See Marketplace Setup Guide for detailed commands:

Overview · Prerequisites · Arguments · Phase 1: Create Marketplace Repository · Phase 2: Install Infrastructure · Phase 3: Link Plugin Repos · Phase 4: Plugin Management · Phase 5: Validate and Verify · Error Handling · Examples

Output

Marketplace repo with marketplace.json + CI/CD + sync scripts; notify-marketplace.yml on each linked plugin repo.

Error Handling

PAT needs repo+workflow. Dispatch missing: confirm notify-marketplace.yml on plugin default branch. Run validate_marketplace.py --verbose. Full troubleshooting: below.

Examples

Input: new marketplace → Output: creates repo, installs CI/CD, generates README. Input: --link org/my-plugin → Output: fetches metadata, adds entry, installs notify-marketplace.yml.

What ships with it

11 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.

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.
