codex-swarm SKILL.md — Before/After Behavior Guide

CRITICAL 1: File Reads Rule

Before: "ZERO file reads" — absolute ban on all file reads. After: "NO source file reads" — nuanced rule with explicit allowlist.

Scenario	Before (broke rule)	After (legitimate)
`git diff --stat` after workers finish	❌ Violated "ZERO file reads"	✅ Explicitly allowed

The Great Split: 197 Rust Files Under 500 Lines

TL;DR

We enforced a strict 500-line maximum on every .rs file in the Script Kit GPUI codebase — a 328,000-line Rust project — using a swarm of 25 autonomous Codex agents working in parallel.

The Numbers

Insight Apps: 50 TypeScript CLI Tools for the AI-Native Developer Workflow

Built in a single session using a Codex (GPT-5.3) swarm coordinated by Claude Code. Each tool is a standalone TypeScript CLI with tests, structured logging, and clean architecture. Here's how they weave into a daily workflow.

Vercel-Native Agent Hub (Demo 13) - Architecture Diagram

This diagram illustrates the complete flow of the Vercel-Native Agent Hub system, which orchestrates 15 specialized agents to build Vercel-native applications using a TDD workflow with quality gates.

System Overview

15 Total Agents: 1 PM Hub + 7 Core Advisors + 2 Optional Advisors + 5 Builders
Capability Scoping: Each agent has specific tool permissions (no dangerously-skip-permissions)
Quality Gates: Architect Gate, QA Gate, and GitOps verification
TDD Workflow: Tests are written first, then implementation, then verification

Agent Hub Flow Diagram

This diagram illustrates the multi-agent orchestration system from 12-agent-hub.ts.

Vercel AI Gateway OIDC Authentication Failure in Workflow DevKit

Executive Summary

When using the Vercel AI SDK with Workflow DevKit, AI Gateway authentication fails with GatewayAuthenticationError even when VERCEL_OIDC_TOKEN is present in the environment. The root cause is that the @vercel/oidc package requires Node.js fs module for token validation/refresh, which is not available in the workflow sandbox.

Environment

AI SDK Version: 6.0.50 (also tested with 5.0.76)
@ai-sdk/gateway: 3.0.23
