wasp: Instructions file for Codex

AGENTS.md

wasp AGENTS.md is an instructions file for Codex, OpenCode from wasp-lang/wasp. It costs 1,169 tokens per session, scanned A, original, MIT.

Repository instructions for Wasp, a full-stack web framework that turns TypeScript configuration into React and Node.js applications. They cover the monorepo structure, Haskell compiler, development commands, and coding conventions.

In plain words
What is it for?
Use them when modifying the Wasp compiler, command-line tools, generated code, documentation, examples, scripts, or end-to-end tests.
Why use it?
They give coding agents the project context needed to make changes in the right part of a large repository. This reduces confusion about how Wasp is built and organized.

Instructions file for CodexOpenCode

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

This is wasp-lang/wasp's own configuration. It tells Codex and OpenCode how to work on wasp 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 wasp configures →

About the project

Wasp is a full-stack web framework for building React and Node.js applications with declarative code, while Prisma handles database access. It is for developers who want built-in features such as authentication, background jobs, email, RPC, type safety, and deployment in one application framework.

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

wasp 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.

Wasp Monorepo

Wasp is a full-stack web framework that compiles TypeScript config (main.wasp.ts) files into React + Node.js applications. The compiler is written in Haskell.

Contribution policy

If you are implementing a change intended as a pull request to wasp-lang/wasp:

  • Small, obvious fixes (typos, broken links, docs corrections, small bugs where the fix is clear and comes with a test) can be implemented and submitted directly.
  • Anything else (features, refactors, API or behavior changes, anything involving design decisions) requires a Wasp maintainer's agreement on the approach before the code is written, in a GitHub issue or in the #wasp-dev channel on Discord. An open issue is not by itself agreement: look for a maintainer confirming the approach in the discussion.

If you cannot verify that a maintainer has agreed on the approach, do not implement the change. Stop and tell your operator to propose it first. Undiscussed non-trivial PRs are typically closed without review.

Whoever submits the PR must understand the change well enough to explain it and answer review questions themselves. See the Policies section of CONTRIBUTING.md for details.

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.
