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 | $0.00094 | $0.01379 |
| Opus 5 | $0.00047 | $0.00690 |
| Sonnet 5 | $0.00019 | $0.00276 |
| Haiku 4.5 | $0.00009 | $0.00138 |
Grade A, and why
mushi-setup 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 7d 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.

Mushi Mushi Setup
Overview
Mushi Mushi is a TDD/PDCA engine for web apps: it captures bugs, maps user stories from your live app, auto-generates Playwright tests, and continuously improves them via PDCA loops.
Console URLs
| Environment | Base URL |
|---|---|
| Hosted (default) | https://kensaur.us/mushi-mushi/admin |
| Local monorepo | http://localhost:6464 after pnpm dev |
| Override | MUSHI_CONSOLE_URL (CLI + browser opens) |
Resolution order: env → saved consoleUrl in ~/.config/mushi/config.json → localhost probe → monorepo heuristic → hosted.
Command matrix
| Command | Use when |
|---|---|
npx mushi-mushi / mushi init |
First SDK install — framework detect, packages, .env.local |
mushi connect --project-id <uuid> --endpoint <url> --write-env --wire-ide --wait |
Have ID + key; want env + Cursor MCP + heartbeat proof |
mushi login |
Save credentials before other commands |
mushi setup |
MCP-only wiring from saved config (not SDK install) |
Do not mint SDK keys under Settings → BYOK. Use Setup → Verify → Generate API key (report:write).
Quick Start (5 steps)
1. Get your project credentials
Open the Mushi admin console (local: http://localhost:6464).
- Setup → Steps or Projects → New project — create a project.
- Copy Project ID (UUID) from the success panel immediately after Create.
- Setup → Verify — Generate API key (
report:write). Shown once.
Or run npx mushi-mushi — the wizard opens /onboarding?tab=steps&setup=cli, verifies via whoami, then installs.
You need:
MUSHI_PROJECT_ID— UUID from success panel or Projects chipMUSHI_API_KEY—mushi_…from Verify tab
2. Install the SDK
# Recommended — wizard handles framework + env
npx mushi-mushi
# Or manual
npm install @mushi-mushi/web
3. Initialize in your app
import { Mushi } from '@mushi-mushi/web'
Mushi.init({
projectId: process.env.MUSHI_PROJECT_ID!,
apiKey: process.env.MUSHI_API_KEY!,
capture: {
discoverInventory: {
enabled: true,
routeTemplates: ['/items/[id]', '/users/[userId]/profile'],
},
},
})
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.

mushi-setup is a skill published in the GitHub repository kensaurus/mushi-mushi (3 stars, last pushed 10d ago), licensed MIT. It adds 94 tokens to every session and 1,379 once invoked, about $0.0005 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.
