Written for Codex and OpenCode: the file is AGENTS.md.

This is orval-labs/orval's own configuration. It tells Codex and OpenCode how to work on orval itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything orval configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

orval 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 1mo 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.

What it actually says

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, and it invokes Vite through vp dev and vp build. Run vp help to print a list of commands and vp <command> --help for information about a specific command.

Docs are local at node_modules/vite-plus/docs or online at https://viteplus.dev/guide/.

Built-in Commands vs Scripts

vp <name> runs a built-in command. vp run <name> runs a package.json script or a vite.config.ts task. Scripts cannot overwrite built-ins, so vp dev and vp run dev may do different things. Check package.json and vite.config.ts first, and run vp run <name> when the project defines a script or task with that name.

Tool Versions

Run vp toolchain to show versions and relationships in the active Vite+ release. Add a tool name to select part of the graph. For example, run vp toolchain vite. Use --global to ignore the local vite-plus package. Use vp why <package> to show the package-manager dependency graph.

Review Checklist

  • Run vp install after pulling remote changes and before getting started.
  • Run vp check and vp test to format, lint, type check and test changes.
  • Check if there are vite.config.ts tasks or package.json scripts necessary for validation, run via vp run <script>.
  • If setup, runtime, or package-manager behavior looks wrong, run vp env doctor and include its output when asking for help.

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.
