redai: Instructions file for Codex

AGENTS.md

redai AGENTS.md is an instructions file for Codex, OpenCode from kpolley/redai. It costs 890 tokens per session, scanned A, original, MIT.

Repository instructions for RedAI, a Bun and TypeScript terminal application that uses AI agents to scan code for security vulnerabilities and validate findings.

In plain words
What is it for?
Use them when working on RedAI's terminal interface, analysis, scanning, validation, agent providers, reporting, or shared domain types.
Why use it?
They give an agent the project map, commands, and rules needed to modify the scanner without breaking its pipeline or interfaces.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions Codex.

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

redai 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.

Repository Guidelines

Project Overview

RedAI is a Bun/TypeScript TUI for AI-assisted vulnerability scanning and validation. It scans source directories, uses Claude Code or Codex SDK agents for threat modeling and finding generation, and runs validator plugins against prepared browser or iOS simulator environments.

Code Map

  • src/tui/ — Ink UI, screens, keyboard handling, and runtime state hooks.
  • src/domain/ — Zod schemas and shared domain types.
  • src/pipeline/ — run lifecycle, persistence, preflight, and the staged scan pipeline.
  • src/analysis/ — source language detection, tree-sitter wiring, and symbol/regex extraction (the "analysis units" step).
  • src/scanner/ — source context loading, scanner provider implementations, and scanner prompts.
  • src/planner/ — validation planning and matching findings to validator environments.
  • src/validators/ — validator plugins (browser, iOS simulator) and the validator-plugin.ts interface.
  • src/agents/ — provider adapters. claude/ and codex/ hold agent-session wrappers; anthropic/ and openai/ hold structured-output helpers; agent-runner.ts is the shared runner entry.
  • src/artifacts/ and src/reporting/ — persisted run artifacts and Markdown/JSON report generation.
  • src/config/ — local environment loading (.env).
  • src/utils/ — shared helpers.

Commands

  • bun install — install dependencies.
  • bun run redai (or bun run dev) — launch the TUI.
  • bun run typecheck — tsc --noEmit.

Invariants

Hard rules. Don't relax these without discussion.

  • Bun only. Do not add an alternate package manager lockfile.
  • Don't mutate target source. Scanner and validator agents must not edit files in the directory being analyzed.
  • Artifacts go to ~/.redai/. Generated PoCs, helper scripts, logs, screenshots, and notes must be saved under ~/.redai/runs/<runId>/ — never written into the target source tree.
  • Persisted and cross-module shapes go through Zod in src/domain/.

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.
