team-foundry: Instructions file for Codex

AGENTS.md

team-foundry AGENTS.md is an instructions file for Codex, OpenCode from tomershahar/team-foundry. It costs 621 tokens per session, scanned A, original, MIT.

Project instructions for AI coding tools working in the team-foundry repository. They define which files to read first, available commands, and rules for making changes.

In plain words
What is it for?
Use them before implementing features in the TypeScript Node CLI, including its build, type-checking, linting, and test workflow. TDD means writing tests to guide development.
Why use it?
They provide a fixed startup checklist and development constraints, reducing the chance of changing code without understanding the project or leaving the build in a broken state.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is tomershahar/team-foundry's own configuration. It tells Codex and OpenCode how to work on team-foundry 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 team-foundry 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

team-foundry 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 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.

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.

AGENTS.md - create-team-foundry

Project Overview

create-team-foundry is an open-source Node CLI (npx create-team-foundry) that scaffolds structured context files into any repo so AI coding tools (Claude Code, Gemini CLI, Cursor) can read team outcomes, decisions, and quality bars natively.

Tech stack: TypeScript, Node 18+, tsup (build), vitest (tests), @clack/prompts (interactive CLI)

Startup Rules

Before writing any code, complete in order:

  1. Read this file completely.
  2. Read CLAUDE.md for project overview, design decisions, and quality standards.
  3. Read ARCHITECTURE.md to understand the layer structure.
  4. Read PROGRESS.md to find current iteration state and next steps.
  5. Read feature_list.json to see current feature status.

Do NOT run bash init.sh - it is currently empty.

Run Commands

  • Install: npm install
  • Build: npm run build
  • Dev (watch): npm run dev
  • Tests: npm test - do not run this directly; share the command with the user and ask them to run it
  • Type check: npx tsc --noEmit
  • Lint: npm run lint

Hard Constraints

  • All code must pass type checking before commit
  • Do not commit broken builds
  • TDD per iteration - tests must pass before an iteration is complete
  • No silent writes - user always confirms before files are modified
  • Generated content must read as written by a thoughtful senior PM, not a template
  • Hell-yes standard: every file, coaching behavior, and onboarding question must be obviously essential or it's cut

Testing

  • Tests live in src/__tests__/
  • Test runner: vitest
  • Never run npm test yourself - tell the user to run it and share output with you

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.
