tiny-world-builder AGENTS.md

tiny-world-builder AGENTS.md is an instructions file for Codex, OpenCode from jasonkneen/tiny-world-builder. It costs 2,585 tokens per session, scanned A, original, AGPL-3.0.

Project instructions for an AI coding agent working on the tiny-world-builder repository. They describe the project structure, local skills, coding style, and the role of an AGENTS.md file.

In plain words
What is it for?
Use them when an AI agent is inspecting, changing, or extending the tiny-world-builder codebase and needs its local rules.
Why use it?
They give the agent the repository-specific context needed to make changes consistently. This reduces guesswork about where files belong and how work should be done.

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

tiny-world-builder 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 4d 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.

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.
