Why use it?
It gives contributors a clear place for documentation, development-environment, and platform changes, along with the commands used to verify them.

Instructions file for CodexOpenCode

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

This is purton-tech/rust-on-nails's own configuration. It tells Codex and OpenCode how to work on rust-on-nails 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 rust-on-nails 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

rust-on-nails AGENTS.md scanned grade A with 1 finding 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 2mo 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.

Rust on Nails Agents Guide

This repository mixes several deliverables that move at different speeds. To keep things tidy, we split the work into three "agents" that each own one slice of the Rust on Nails experience. Use this guide to decide where changes belong and how to validate them before opening a PR.

Documentation Agent (crates/static-website)

  • Purpose: Publish the public site that explains how to build Rust on Nails applications. The site is deployed to Cloudflare Pages.
  • Primary tasks: Add or update docs in content/ and assets in assets/. When adding tutorials, prefer runnable snippets that match the default project template.
  • Working locally: Run just wts for Tailwind and just ws for the Rust/Dioxus generator. Browse http://localhost:8080 to preview the rendered pages under dist/.
  • Before shipping: DO_NOT_RUN_SERVER=1 cargo run --bin static-website to ensure the generator succeeds, then run the Cloudflare preview workflow if build or deployment config changed.

Dev Environment Agent (nails-devcontainer)

  • Purpose: Maintain the reusable development environment used by community members and contributors.
  • Primary tasks: Keep devcontainer-template.json and wrapper scripts in sync with the CLI and website. Document required tooling in README.md.
  • Working locally: Use devcontainer up (VS Code) or devcontainer build --workspace-folder . to verify changes. Ensure the container exposes port 8080 for the docs server and ships the CLI binaries or aliases referenced in the guides.
  • Before shipping: Bump version tags when you change the base image or toolchain. Run at least one full cargo test inside the container to make sure the toolchain works.

Platform Agent (crates/stack-cli)

  • Purpose: Provide the internal deployment/PaaS layer that installs operators into Kubernetes clusters for Rust on Nails applications.
  • Primary tasks: Extend the stack-cli binary, manage Helm-like manifests under config/, and maintain integrations with Envoy and Keycloak.
  • Working locally: cargo run --bin stack-cli -- -h to inspect commands. Use cargo run --bin stack-cli -- operator to run the controller loop, and the init/install subcommands to configure a cluster. The dev container already maps your kubeconfig—fall back to tmp/kubeconfig if needed.
  • Before shipping: cargo fmt, cargo clippy -- -D warnings, and cargo test. When changing cluster assets, test against a local K3s install (curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC='server --write-kubeconfig-mode="644"' sh -). Document any new flags in README.md.

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.
