pip-web: Instructions file for Codex

AGENTS.md

pip-web AGENTS.md is an instructions file for Codex, OpenCode from playpip/pip-web. It costs 710 tokens per session, scanned A, original, MIT.

Repository instructions for Pip, a local, play-money Texas Hold'em game played against computer opponents. They describe the code layers, project documentation, tools, tests, and design rules.

In plain words
What is it for?
Use them when changing Pip's poker rules, game flow, saved player data, interface, documentation, or tests.
Why use it?
They give coding agents the game context and prevent changes from crossing boundaries or using the wrong package manager, test runner, or design tokens.

Instructions file for CodexOpenCode

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

This is playpip/pip-web's own configuration. It tells Codex and OpenCode how to work on pip-web 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 pip-web 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

pip-web 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.

AGENTS.md

Guidance for AI agents working in this repo (Pip — a clean single-player Texas Hold'em web app). This mirrors CLAUDE.md; full docs are in docs/. Read the relevant doc before non-trivial work.

Orientation

  • What it is: play-money, local-first, desktop-first Hold'em vs AI. No account needed; there is an optional one for cross-device sync only. GitHub repo: playpip/pip-web.
  • Three layers (don't cross the boundaries):
    1. src/lib/poker/ — pure, deterministic, unit-tested engine (the rules).
    2. src/store/ — game.ts (pacing/AI/economy), profile.ts (persisted).
    3. src/components/, src/app/ — presentation only.

Where to read

Non-negotiables

  • pnpm for everything; never hand-pin versions.
  • AVA for tests (not Vitest); engine changes ship with tests.
  • Theme tokens only for colour (foreground/<alpha>, bg-primary). Dark only — there is no light mode. Never hardcode white/black.
  • No real-money framing: "chips", never $; no casino textures or pop-ups.
  • Engine is pure & deterministic (seeded Rng; no React/store imports).
  • Persisted-schema changes bump PERSIST_VERSION + add a migration.
  • Obey the set-state-in-effect rule — by convention (see docs/development.md).

Definition of done

pnpm test:all passes — format, types, lint (biome), AVA, knip, audit — (plus pnpm build for structural changes). Verify UI by running pnpm dev. Commit/push only when asked.

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.
