Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.00806 |
| Opus 5 | $0.00000 | $0.00403 |
| Sonnet 5 | $0.00000 | $0.00161 |
| Haiku 4.5 | $0.00000 | $0.00081 |
Grade A, and why
happy-start.template 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.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex Runtime Compatibility
This prompt was authored for Claude-style slash workflows. In Codex runtime, adapt tool calls as follows:
AskUserQuestion=> ask the user directly in chat.WebSearch/WebFetch=> use available web tools (search_query,open,find) and cite links.Read/Write=> use shell/filesystem tools in this workspace.- Claude-only MCP calls (for example Playwright MCP names) => use available equivalents or clearly state fallback.
- Keep intent and output format identical; only adapt execution mechanics.
happy-start — Codex Runtime
This command starts the Happy Engineering development environment. Happy MCP tools are Claude Code CLI-specific and unavailable in Codex.
What I Can Do
Start your development server manually:
# Start the dev server (common options)
npm run dev # Vite/React
npm start # CRA
npx next dev # Next.js
python -m uvicorn backend.main:app --reload --port 8001 # FastAPI
Tell me your project type and I'll start the right dev server.
For Happy Engineering MCP integration with dashboard, use Claude Code CLI: /happy-start
description: Start a Happy Mode session for mobile app integration model: sonnet
/happy-start - Launch Happy CLI Session
Launches a new PowerShell terminal with Happy CLI wrapping Claude Code for mobile app control.
What This Does
- Opens a new PowerShell window in the current project directory
- Runs
npx happy-coderwhich wraps Claude Code - Your paired Happy mobile app automatically sees the new session
- Control this Claude session from your phone
Prerequisites
happy-codernpm package installed globally:npm install -g happy-coder- Claude Code CLI authenticated:
claude auth - Happy mobile app paired (run
happy authonce to pair)

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.
