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 | $0.01018 | $0.01018 |
| Opus 5 | $0.00509 | $0.00509 |
| Sonnet 5 | $0.00204 | $0.00204 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade A, and why
oh-my-sage AGENTS.md 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 2d 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.

Project Overview
Xiaomi Mijia smart home AI Agent with dual-mode architecture:
- Web Mode: Next.js 14 + TypeScript + Ant Design + Vercel AI SDK
- MCP Mode: Model Context Protocol server for AI coding assistants
Communicates with Xiaomi gateway via WebSocket+ECJPAKE. Uses LLM tool-calling for smart home automation.
Key Commands
# Web development
npm run dev # Start Next.js dev server
npm run build # Production build
# MCP development
npm run build:mcp # Build MCP server only
npm link # Link oh-my-sage-mcp command globally
# Quality checks
npm run lint # ESLint (next/core-web-vitals)
npx tsc --noEmit # TypeScript strict mode check
# Testing (manual only, no automated framework)
npm run test # Runs npx tsx src/test.ts
npx tsx <script.ts> # Run single TypeScript file
Note: No Jest/Vitest. All tests are manual integration tests via tsx.

MCP Development
Building: npm run build:mcp outputs to dist/mcp/mcp/index.js
Global command: npm link creates oh-my-sage-mcp in PATH
Local testing: oh-my-sage-mcp (stdio mode)
Configuration (for OpenCode/Claude/Cursor):
{
"mcpServers": {
"oh-my-sage": {
"command": "npx",
"args": ["-y", "oh-my-sage-mcp"]
}
}

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.

oh-my-sage AGENTS.md is an instructions file published in the GitHub repository allocnode/oh-my-sage (77 stars, last pushed 7d ago), licensed MIT. It adds 1,018 tokens to every session, about $0.0051 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 2026-08-30.
