minimal-realtime-kit: Instructions file for Codex

AGENTS.md

minimal-realtime-kit AGENTS.md is an instructions file for Codex, OpenCode from RayFernando1337/minimal-realtime-kit. It costs 1,871 tokens per session, scanned A, original, MIT.

Project instructions for developing MinimalRealtimeKit, an open-source iPhone app that provides a voice-based AI agent with tool calling. They record the project’s fixed facts, development plan, and ways to build, test, install, and capture screenshots.

In plain words
What is it for?
Use them when modifying, building, debugging, or checking MinimalRealtimeKit on an iOS simulator.
Why use it?
They give coding agents the project rules and verification steps they need, reducing the risk of changing the wrong files, drifting from the design, or exposing secrets.

Instructions file for CodexOpenCode

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

This is RayFernando1337/minimal-realtime-kit's own configuration. It tells Codex and OpenCode how to work on minimal-realtime-kit 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 minimal-realtime-kit configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/ray/Projects/AIProxyRealtime2Demo/minimal-realtime-kit.

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

minimal-realtime-kit 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.

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — minimal-realtime-kit

A minimal, bring-your-own-key iOS voice agent: realtime voice + tool calling against the latest OpenAI GPT Realtime API, distilled into a clean, PUBLIC open-source repo. Voice is OpenAI Realtime via AIProxySwift (direct BYO-key mode) over AVFoundation; the mic is always open. Tools render agent-driven cards via a data-only factory; an audio-reactive SpriteKit character embodies the agent.

Read first, in order: SPEC.md (architecture + invariants N1–N6 + the latest-API truth + decision D1) → PROJECT-PLAN.md (tiers, task cards T0.1…T5.x, the wave table §3, the verify loop §4). Then the research/01..07 file(s) and snippets/* your task card cites. This repo is PUBLIC — secret hygiene is non-negotiable (N1).

Canonical project facts (do not drift)

  • Project: MinimalRealtimeKit.xcodeproj · scheme MinimalRealtimeKit · target/product MinimalRealtimeKit.
  • Bundle id: com.example.MinimalRealtimeKit (neutral — never a com.rayfernando.* id or any Apple Team ID).
  • App source dir: MinimalRealtimeKit/ — a PBXFileSystemSynchronizedRootGroup: new files in this folder auto-include in the target. NEVER hand-edit the .pbxproj. (Config templates live in Config/.)
  • Deployment target: iOS 26.0. Sim: iPhone 17 Pro (iOS 26.x). An iOS 18 sim cannot install.
  • One SPM dependency: AIProxySwift 0.153.0 (MIT), product AIProxy. No other third-party deps.
  • Default actor isolation is MainActor (SWIFT_DEFAULT_ACTOR_ISOLATION = MainActor, SWIFT_APPROACHABLE_CONCURRENCY = YES, Swift language mode 5.0). The realtime networking layer is the @AIProxyActor global actor; mark its members nonisolated where they cross to the stream.

Build / Run / Verify

Use the XcodeBuildMCP tools (preferred) or xcodebuild. Build Debug AND Release for every change (Release proves nothing leaked outside #if DEBUG). There is no test target and no CI — the build + sim-screenshot + grep loop below is the only safety net; the live realtime loop cannot be driven headlessly (no live key/backend in QA), so verify the realtime invariants by code audit.

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.
