This is bishopZ/2026-Boilerplate's own configuration. It tells Codex and OpenCode how to work on 2026-Boilerplate 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 2026-Boilerplate 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

2026-Boilerplate 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.

Development Setup

  1. Requires Node.js >= 24.13.1 and npm >= 11.10.1
  2. Copy .envTemplate to .env if .env doesn't exist
  3. Run npm install
  4. Run npm run dev to start the dev server on port 3000

Key Commands

  • npm run dev — development server (Express + Vite HMR)
  • npm run lint / npm run lint:fix — ESLint
  • npm run type-check — TypeScript type verification
  • npm run build — production build
  • npm run test — Full suite: lint + type-check + unit + E2E
  • npm run test:unit — Vitest unit tests (no dev server needed)
  • npm run test:e2e — Playwright E2E tests (dev server starts automatically via webServer config)

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.
