the-pair: Instructions file for Codex

AGENTS.md

the-pair AGENTS.md is an instructions file for Codex, OpenCode from timwuhaotian/the-pair. It costs 4,512 tokens per session, scanned A, original, Apache-2.0.

A repository guide for The Pair, a Tauri desktop app where a read-only Mentor agent reviews work and an Executor agent writes code and runs commands.

In plain words
What is it for?
Use it when changing the Tauri commands, Rust backend, React and TypeScript frontend, agent coordination, state management, styling, or related project code.
Why use it?
It tells coding agents how the Rust backend and React frontend must communicate and documents the project's technology and architecture rules.

This is timwuhaotian/the-pair's own configuration. It tells Codex and OpenCode how to work on the-pair 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 the-pair 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

the-pair AGENTS.md scanned grade A with 1 finding 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 16d 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.

AI Agent Guidelines for "The Pair"

This file contains instructions and context for any AI agents (like yourself) working on the the-pair repository.

Project Identity

"The Pair" is a Desktop application (v1.2.3) built with Tauri 2.x, React 19, and TypeScript. It orchestrates two local AI agents — a Mentor (planner/reviewer, read-only) and an Executor (code writer/command runner) — that cross-check each other's work. The app manages their lifecycle, monitors resources, tracks git changes, and provides a polished UI for humans to observe and intervene.

Tech Stack

  • Framework: Tauri 2.0
  • Backend: Rust
  • Frontend: React 19, TypeScript
  • Styling: Tailwind CSS v4, clsx, tailwind-merge
  • Icons: lucide-react
  • State Management: zustand (usePairStore, useUpdateStore, useThemeStore)
  • Animations: Framer Motion

Architecture Rules

  1. Rust Backend vs. React Frontend:
    • Never import Node.js built-ins directly into the Renderer (src/renderer/src/).
    • Use Tauri commands in src-tauri/src/ to expose strict APIs to the frontend.
    • Frontend calls backend via invoke() from @tauri-apps/api/core.
  2. Styling:
    • Always use Tailwind CSS classes. Custom dark/light mode palette is defined in src/renderer/src/assets/main.css.
    • Shell chrome (sidebar, hub, inspector, modals, palette) uses sans (font-sans, Geist Sans/SF); the conversation core (pair stream, diffs, code) uses mono (font-mono, Geist Mono). Never re-mono shell labels or re-sans the stream — tests/shellTypography.test.ts pins the split.
    • Shell surfaces use .shell-card (+ .shell-card-hover); the sidebar rail uses .app-source-list. The stream stays flat with hairline borders.
    • Use the cn() utility from src/renderer/src/lib/utils.ts for conditional class merging.
  3. Agent Interactions:
    • The application spawns processes. Always implement an iteration limit (maxIterations) before pausing for human intervention.
    • Use the handoff guard (src/renderer/src/lib/handoffGuard.ts) to prevent race conditions when pairs finish.
  4. Error Handling:
    • Handle permissions and locked files defensively in the Rust backend.
    • Propagate errors cleanly to the frontend via Tauri commands to display in the ErrorDetailPanel.

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.
