thinkex: Instructions file for Codex

AGENTS.md

thinkex AGENTS.md is an instructions file for Codex, OpenCode from ThinkEx-OSS/thinkex. It costs 166 tokens per session, scanned A, original, MIT.

A set of project instructions for ThinkEx-OSS/thinkex, a study and research project that is expected to use sources. It explains how to handle early-stage code, documentation, branches, and automatic deployments.

In plain words
What is it for?
Use it to guide changes in the ThinkEx-OSS/thinkex repository, including deciding what belongs in commits, how to treat greenfield code, and how deployments work.
Why use it?
It gives coding agents consistent rules for shipping changes, handling research notes, and understanding that pushes to the main or staging branch deploy automatically. This reduces mistakes such as adding unnecessary compatibility code or expecting a manual deployment step.

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

This is ThinkEx-OSS/thinkex's own configuration. It tells Codex and OpenCode how to work on thinkex 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 thinkex 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

thinkex 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.

What it actually says

Agent notes

  • Early-stage repo with effectively no users: treat changes as greenfield. No legacy shims, no back-compat paths, and no data migrations for existing rows unless explicitly requested. Prefer deleting superseded code over keeping it reachable.
  • Merging IS shipping: Cloudflare Workers Builds auto-deploys every push to main to production (wrangler migrations included). The staging branch deploys to the staging env the same way. There is no manual deploy step.
  • Commits carry code and the docs that ship with it. Research notes, analysis writeups, and other non-shipping generated markdown (e.g. docs/research/) stay as untracked working files — commit them only when explicitly asked.
Changes

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.
