Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions AGENTS.md; mentions Codex.

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

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

bex 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 3d 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.

Origin

This is a copy

100% identical to superpowers AGENTS.md — 168 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

bex is the open-source Render alternative — AI-native (ADR008). A Go Kubernetes operator reconciles App CRs (app.bex.co/v1alpha1, bex-system) into running services. All Go lives in lego/ (Latin legō, "I assemble") — one image, four workspace modules: types/ (CRD contract, leaf), operator/ (mechanism, DB-free manager), backend/ (bex-api on :8090 + SSH gateway), cli/ (Render CLI launcher, bex-cli/v* train). operator → types ← backend; cli imports none.

Repo map

  • lego/ — all Go, self-contained (go.work, Dockerfile; context lego/). README, workspace rules.
    • lego/types/ — App/Database CRD types
    • lego/operator/ — manager → Deployment/Service/Ingress; owns config/ + codegen. operator guide
    • lego/backend/ — bex-api (REST/GraphQL/MCP + OpenFGA) + ssh-gateway. backend guide
    • lego/cli/ — bex CLI launcher (pinned render-oss/cli). README
  • dashboard/ — TanStack Start + Apollo + shadcn, client of bex-api GraphQL. dashboard guide
  • infra/ — day-0: Terraform + Cluster API (local-capd ⇄ hetzner-caph)
  • deploy/gitops/ — day-1: Argo CD platform infra (not user deploys)
  • examples/ — whoami-app.yaml, hello-go/
  • scripts/ — cluster helpers (mock-cluster.sh, app-apply.sh, deploy-sample.sh)
  • docs/ — one file per topic. Full catalog in docs/AGENTS.md
  • .pm/ — internal PM board (may be stale). Conventions in .pm/AGENTS.md

Commands

All make targets live in lego/operator/; see lego/AGENTS.md for workspace Go-version split + codegen. CI gates:

  • make test (operator, from lego/operator/) — CRD/RBAC codegen + envtest
  • cd lego/backend && go test ./... — backend (real Postgres + OpenFGA in CI)
  • make lint (all four modules) — golangci-lint + whole-program dead-code analysis; depguard guards the id convention
  • cd lego/cli && go test ./... — CLI launcher

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.
