core: Instructions file for Codex

AGENTS.md

core AGENTS.md is an instructions file for Codex, OpenCode from Bridge-UI/core. It costs 420 tokens per session, scanned A, original, MIT.

Repository instructions for Bridge UI, a code library with React and Vue packages, maintained in one shared repository called a monorepo.

In plain words
What is it for?
Use them when building with Bridge UI or changing its core, React, or Vue packages, documentation, examples, or release files.
Why use it?
They tell a coding agent which instructions and documentation apply when using Bridge UI or contributing to it, preventing work in the wrong package or folder.

Instructions file for CodexOpenCode

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

This is Bridge-UI/core's own configuration. It tells Codex and OpenCode how to work on core 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 core 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

core 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.

Bridge UI — agent instructions (monorepo)

This repository builds @bridge-ui/core, @bridge-ui/react, and @bridge-ui/vue.

Which instructions to follow

You are… Read
Building an app that uses Bridge Package AI + docs: packages/react/ai / packages/react/docs (or vue). Or run npx bridge-ui-*-ai install in the app
Contributing to this monorepo .cursor/rules/ (patterns, docs examples, commits)

Do not mix the two.

Consumer packages (source of truth)

Package AI Docs
@bridge-ui/react packages/react/ai/ packages/react/docs/ (components/, examples/)
@bridge-ui/vue packages/vue/ai/ packages/vue/docs/ (components/, examples/)
npm install @bridge-ui/react
npx bridge-ui-react-ai install

Skills are thin routers — examples live in package docs/.

Ready-made adapters (date, icon, i18n) live in a separate repository: Bridge-UI/adapters (@bridge-ui/adapters). This monorepo only owns the adapter contracts in @bridge-ui/core/Adapters.

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.
