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 | $0.01461 | $0.01461 |
| Opus 5 | $0.00731 | $0.00731 |
| Sonnet 5 | $0.00292 | $0.00292 |
| Haiku 4.5 | $0.00146 | $0.00146 |
Grade A, and why
tanstack-hono 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.
How it starts
The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Agent Guidelines
Full-stack React SSR app — TanStack Router (file-based routing) + Hono (server/SSR) + Vite+ + TypeScript.
Essentials
- Package manager:
vp— never callnpm/pnpm/yarnfor installs or tooling (npm startfor running the built server is fine) - Never edit
src/routeTree.gen.ts(auto-generated) vp run build— build client + server |vp check— format + lint + typecheck |vp test— run tests
Guides
- Commands — dev, build, lint, test
- Architecture — entry points, request flow, project structure
- Routing & Data — file-based routes, loaders, TanStack Query
- Server/API — Hono routes, RPC client
- Code Style — conventions, imports, naming
- Testing — Vitest setup, jsdom, globals
- Environment Variables — VITE_ prefix, access patterns
- Styling — Tailwind CSS v4
- Streaming SSR — optional, deferred data
- Deployment — build outputs, production targets
- Pitfalls — top 3 common mistakes
Using Vite+, the Unified Toolchain for the Web
This project is using Vite+, a unified toolchain built on top of Vite, Rolldown, Vitest, tsdown, Oxlint, Oxfmt, and Vite Task. Vite+ wraps runtime management, package management, and frontend tooling in a single global CLI called vp. Vite+ is distinct from Vite, but it invokes Vite through vp dev and vp build.
Vite+ Workflow
vp is a global binary that handles the full development lifecycle. Run vp help to print a list of commands and vp <command> --help for information about a specific command.
Start
- create - Create a new project from a template
- migrate - Migrate an existing project to Vite+
- config - Configure hooks and agent integration
- staged - Run linters on staged files
- install (
i) - Install dependencies - env - Manage Node.js versions
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.
