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

codex-toolloop 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.

Repository Guidelines

Setup

  • Node.js 24+ (.nvmrc), pnpm (Corepack: corepack enable).
  • Copy .env.example to .env; never commit real keys.

Project Layout

  • apps/cli/: CLI entrypoint (apps/cli/src/index.ts).
  • packages/: workspace packages
    • packages/codex-toolloop/: core runtime scaffold
    • packages/codex/: Codex backends (app-server / exec / sdk)
    • packages/mcp/: MCP tool substrate + policy
    • packages/workflows/: workflow + routing utilities
    • packages/testkit/: fixtures/mocks/temp dirs
  • src/: root exports + prototype workflows
  • tests/unit/: Vitest runtime tests; tests/type/: *.test-d.ts
  • docs/: PRD, ADRs (docs/adr/), specs (docs/specs/)
  • examples/: runnable scripts (pnpm examples:*)

Commands

pnpm install
pnpm dev:cli -- doctor
pnpm build
pnpm fix:typecheck  # required before finishing work
pnpm test
pnpm test:watch
pnpm examples:basic

Codex app-server schema upgrades

  • If pinned @openai/codex version changes, run pnpm codex:gen and update integration code for protocol deltas.
  • Guide: docs/codex-app-server-protocol.md (ADR 0013/0014, SPEC 023/024-029).
  • When Codex SDK is involved, use the $codex-sdk skill guide.

Turborepo (Vercel)

  • Use turbo run build on Vercel (filters inferred by root).
  • In turbo.json, define tasks.build.outputs for each framework output dir.
    • Next.js: [".next/**", "!.next/cache/**"]
  • Never include .next/cache/** in outputs.
  • Declare task env + globalEnv to avoid stale cache hits.
  • Validate remote caching locally: turbo run build, then inspect node_modules/.cache/turbo.

Style

  • TypeScript ESM (NodeNext), strict, noUncheckedIndexedAccess, exactOptionalPropertyTypes.
  • Biome (biome.json): 2-space indent, 80-col.
  • Exported schemas use ...Schema; keep exports small and explicit.

Development Standards

Required before you finish:

pnpm -s fix:typecheck (runs pnpm -s fix, pnpm -s typecheck, pnpm -s test). Keep its changes.

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.
