Cursor Codex Gemini CLI Antigravity Hit by Sandbox Escapes
Vince and Ava dig into the sandbox-escape report on Cursor, Codex, Gemini CLI, and Antigravity, focusing on why these agent tools are only as safe as the host tools they can trick into running. They connect the issue to real adoption pressure, the fragile trust boundary around file writes, and the fact that sandboxing is becoming a product feature, not a nice-to-have.

OpenAI's first gadget is the $230 Codex Micro macropad
Onyx and Echo pick apart The New Stack’s argument that OpenAI’s Codex Micro matters less as a gadget and more as a signal: AI coding is turning into a workflow with dedicated controls, not just a chat box. They test whether that claim actually holds up, where it overreaches, and who should care beyond keyboard nerds.

How agents are transforming work
The article discusses how agents, specifically OpenAI's Codex, are transforming work by enabling long-horizon tasks and changing the unit of knowledge work from single interactions to delegated tasks.

AI optimizer beats Claude Code, Codex by 2
Researchers introduce Arbor, a framework that structures AI optimization as a cumulative learning tree instead of isolated trial-and-error loops, delivering 2.5x verifiable gains over Claude Code and Codex on the same compute. It solves the core AO bottleneck: agents forgetting what they’ve learned across long-running experiments.

DietrichGebert/ponytail
Justy and Cody get into Ponytail, a repo that tries to force coding agents to act like the annoying-but-useful senior engineer who deletes half the plan before writing anything. They like the core argument more than the branding: most agent waste comes from inventing code that does not need to exist, and a simple decision ladder can cut code, time, and cost. Cody thinks the benchmark is directionally believable but narrow, while Justy sees immediate value for teams drowning in agent-generated wrappers and helper classes.

Speeding up agentic workflows with WebSockets in the Responses API
Justy and Cody dig into OpenAI’s writeup on speeding up agentic workflows with WebSockets in the Responses API. Cody is skeptical of the hype around raw model speed, while Justy keeps pulling it back to user pain: long, repetitive agent loops that make coding tools feel sluggish. They land on a practical read — the transport change matters most when the model is fast enough that API overhead becomes the bottleneck — and they sketch a weekend experiment for building a tiny stateful agent loop.

An open source spec for Codex orchestration: Symphony.
Symphony is an open-source spec that turns your issue tracker into an agent control plane, letting coding agents pull work continuously instead of requiring constant human supervision. OpenAI built it to solve the bottleneck of context-switching across multiple agent sessions, and saw a 500% increase in landed PRs on some teams. The spec is language-agnostic and designed to be implemented by agents themselves.

Prompt guidance | OpenAI API
Justy and Cody unpack OpenAI’s prompt guidance for GPT-5.5, focusing on shorter outcome-first prompts, personality blocks, preambles for tool use, and retrieval budgets that help agents stop at the right time.
-
Git
Justy and Cody look at ai-cli-mcp, a package that turns several coding agents into background jobs from one MCP server. They focus on why parallel AI work is useful now, how the package routes prompts to Claude, Codex, Gemini, Forge, and OpenCode, and where setup friction and safety trade-offs show up.

Harness engineering: leveraging Codex in an agent First world
Justy and Cody dig into OpenAI’s writeup on building a product with Codex doing all the coding, and why the real shift is from typing code to designing an environment agents can reliably operate in. They cover the no-manual-code constraint, the repo-as-system-of-record approach, agent-readable docs, isolated worktrees, UI and observability access, and why this matters for teams trying to ship faster without drowning in review and QA.

Building frontend UIs with Codex and Figma
OpenAI's new Figma MCP server creates a bidirectional bridge between Figma designs and Codex code generation, allowing developers to extract design context from Figma files for code generation and push live UI back to Figma canvas for iteration. The integration supports full roundtrip workflows from design to code and back.

How PMs use the Codex app
Product managers are using a new app called Codex to bridge the gap between product vision and engineering execution. We explore how it works, why it's gaining traction among PMs, and what makes it different from traditional project management tools.

OpenAI launches new macOS app for agentic coding | TechCrunch
OpenAI's new macOS app for agentic coding is reshaping the landscape of software development by enabling AI agents to autonomously handle complex coding tasks, significantly speeding up the development process. This episode explores how this technology works, its implications for developers, and real-world applications.
