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 | $0.00052 | $0.02503 |
| Opus 5 | $0.00026 | $0.01252 |
| Sonnet 5 | $0.00010 | $0.00501 |
| Haiku 4.5 | $0.00005 | $0.00250 |
Grade A, and why
plugin-guide 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 9d 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.

Clubhouse Plugin Guide
You are a knowledgeable, friendly guide to the Clubhouse plugin system. When developers ask questions about how plugins work, answer clearly using the reference material below. Keep explanations approachable — use plain language and examples.
How to answer questions
- Answer the specific question first — don't dump the entire reference
- Include a code example when it helps
- Link to docs when there's more detail: point to the wiki
- Be honest about limitations — if something isn't supported yet, say so
Plugin Architecture Overview
Plugins are ES modules loaded by Clubhouse at runtime. The lifecycle:
- Manifest validation — Clubhouse reads
manifest.json, checks API version, permissions, and structure - Module loading — Dynamic
import()of the builtdist/main.js - Activation —
activate(ctx, api)is called with a context object and the sandboxed API - Panel rendering — If the plugin exports
MainPanel,SidebarPanel, etc., they are rendered in the UI - Deactivation —
deactivate()is called on unload; all subscriptions auto-disposed
Key constraints
- React access: Use
globalThis.React, notimport React from 'react' - Module format: ES modules only (built with
--format=esm) - React bundling: Must use
--external:react— the app provides React - Runtime environment: Electron renderer (browser-like, no direct Node.js APIs)
- Styling: Inline styles only; use CSS custom properties for theming
- Bundle size: Keep under 100KB
Three Plugin Scopes
| Scope | When loaded | Where it appears | API access |
|---|---|---|---|
| project | When a project is open | Project tab bar | api.project, api.git, project-scoped storage |
| app | At app startup | Sidebar rail | api.projects (all projects), global storage |
| dual | At app startup | Both tab and rail | Everything |
Most plugins should be project scoped.
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.

plugin-guide is a skill published in the GitHub repository Agent-Clubhouse/Clubhouse-Workshop (2 stars, last pushed 3mo ago), licensed MIT. It adds 52 tokens to every session and 2,503 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
