claude-one-button-game-creation: Instructions file for Codex

AGENTS.md

claude-one-button-game-creation AGENTS.md is an instructions file for Codex, OpenCode from abagames/claude-one-button-game-creation. It costs 891 tokens per session, scanned A, original, MIT.

A project instruction file for generating ten browser-playable games with crisp-game-lib, a library for making small web games.

In plain words
What is it for?
Use it to install dependencies, generate the ten-game batch, run tests, and locate the workflow, scripts, input tags, and generated games.
Why use it?
It defines the working folders, standard generation process, setup commands, and expected deliverables so an agent knows how to run the project.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is abagames/claude-one-button-game-creation's own configuration. It tells Codex and OpenCode how to work on claude-one-button-game-creation 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 claude-one-button-game-creation 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

claude-one-button-game-creation 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 7d 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.

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

claude-one-button-game-creation

An automatic one-button game generation project using crisp-game-lib. Agents use random tags as inspiration to design and implement a varied batch of ten browser-playable games.

The standard workflow ends when ten runnable games are presented. Ranking, selection, human review, Polish, retrospective, publication, and play-log mechanical evaluation are separate activities and require an explicit user request.


Working Directory

Run all commands from the project root (the directory containing this file).

  • Generation workflow: ./workflows/game-generation.md
  • Scripts: ./scripts/
  • Static tag inputs: ./data/
  • Generated games: ./tmp/games/

On a fresh clone, run:

npm ci
npm run skills:install
npm run playwright:install
npm test

skills:install copies only the skills required by this project from abagames/agentic-gamedev-skills into the ignored local .agents/skills/ directory. It replaces only those three skill directories and preserves other content under .agents/. To refresh intentionally, run the command again; set AGENT_SKILLS_REF to the desired upstream commit. The generation workflow has no durable-state initialization requirement.


Standard Flow: Generate and Present Ten Games

  1. Confirm tmp/games/ is absent or empty. If it contains anything, stop and ask the user what to do. Do not delete, overwrite, move, or archive existing output without explicit user direction.
  2. Run workflows/game-generation.md once per game with a fresh generation context and fresh tag seed.
  3. Repeat until tmp/games/ contains exactly ten new games.
  4. Smoke-test every game's index.html in a real browser. Repair runtime failures and re-run the failed smoke test.
  5. Present the ten games as an unranked list and stop.

Each game must be generated independently. A game-generation context may read the generation workflow, the relevant skills, its own tags, and its own output, but must not compare against other games in the batch or attempt to select a winner.

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.
