yoke: Instructions file for Codex

AGENTS.md

yoke AGENTS.md is an instructions file for Codex, OpenCode from HECer/yoke. It costs 196 tokens per session, scanned A, original, MIT.

A project instruction file for HECer/yoke that records project context and the rules for making releases. It requires changelog, version, validation, CI, and package-publication checks.

In plain words
What is it for?
Use it when changing yoke or preparing a release so documentation, versions, tests, CI, and npm publication stay aligned.
Why use it?
It keeps proposed ideas separate from implemented behavior and prevents a release from being reported as complete before its checks are verified.

Instructions file for CodexOpenCode

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

This is HECer/yoke's own configuration. It tells Codex and OpenCode how to work on yoke 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 yoke 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

yoke 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 5d 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

Yoke project context

For product strategy, roadmap, provider parity, token/cost optimization, task time estimation, or dashboard work, first read the saved product discussion.

That document distinguishes observed code findings, user preferences, and proposed features. Do not treat proposals as implemented functionality or blanket authorization to implement them. Recheck dated findings against the current code. This file complements the user's global instructions.

Release rule

Every new version must have a dated entry in CHANGELOG.md before it is tagged or published. Describe the implemented features, behavior/default changes, fixes, migration or override instructions, and material validation limits that apply to that release. Keep proposals separate from shipped functionality. Synchronize package, lockfile, provider manifests and README versions, run the release checks, and use the matching changelog entry for GitHub release notes. Verify GitHub CI and npm publication before reporting the release as complete.

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.
