Does Pi Outperform Codex CLI for Local Models? A Harness Comparison on the NVIDIA GB10
The system prompt tax is the cost you pay before your coding agent writes a single line of code.
Codex CLI Offline Mode: Local Models, Air-Gapped Setups, and What Works Without Internet
Can I run Codex CLI without internet? is one of the most common search queries that leads nowhere.
Your First 30 Minutes with Codex CLI: From Install to First Fix
Thirty minutes. That is all you need to go from zero to watching an AI agent autonomously diagnose a bug, write a fix, run the tests.
Transferring ChatGPT Conversations to Codex CLI
Many developers start their thinking in ChatGPT — brainstorming architecture, researching APIs, sketching out approaches with web search — then need to hand.
The Subagent Resource Leak Problem: Why MCP Process Trees Accumulate and What McpConnectionManager::shutdown() Fixes
If you run Codex CLI with multiple MCP servers and use subagent workflows, you have almost certainly experienced the symptoms.
Self-Evolving Agents in Practice: Implementing the OpenAI Cookbook Retraining Loop with Codex CLI Hooks
Most agentic systems plateau after proof-of-concept. The agent handles the happy path, but edge cases accumulate, prompts drift, and performance quietly.
Running Multiple Codex Agent Instances: Parallel Orchestration Patterns
Running a single Codex CLI agent is powerful. Running several in parallel — each tackling an independent slice of your codebase — transforms your throughput.
Policy-as-Code for Coding Agents: From the OpenAI Governance Cookbook to Codex CLI guardrails
Every organisation deploying coding agents hits the same wall: security wants to audit, legal wants guardrails, and engineering wants to ship.
When to Use Multi-Agent vs Single-Agent: A Practical Framework for Codex CLI Teams
Codex CLI's subagent system lets you spawn parallel agents for concurrent work — but more agents does not always mean better results. Recent academic.
Git-Backed Team Memory for Coding Agents: From Egregore to Codex Hooks
Every developer team already has a shared, versioned, conflict-resolving knowledge store: git. Yet most AI coding agents treat memory as a single-user.
