Swapping the model is one click — but the thing that actually locks you in moved one layer up, into the harness you configure around it. ## Key takeaways - GitHub's Agent HQ now lets you pick the agent — Claude or Codex, alongside Copilot's own — inside VS Code, the JetBrains IDEs, and Copilot CLI, selected from an agent picker rather than wired in at build time. - The model is now genuinely a dropdown: install the provider's CLI, point Copilot at it, and switch per task. That kills the cheapest kind of lock-in — the one where changing your default model meant changing tools. - But the lock-in didn't disappear; it moved up a layer. Your approval rules, hooks, MCP server list, and custom instructions now live in GitHub's 'Agent Customizations,' and that harness — not the model — is what your team's muscle memory and automations bind to. - The founder move: treat the model as swappable and benchmark Claude vs Codex per task on your real repo, but keep the harness config (hooks, MCP, approvals) in version control you own, so the layer that actually holds you doesn't live only in a vendor's settings pane. ## At a glance | Layer | Before Agent HQ | After Agent HQ | Where the lock-in sits now | | --- | --- | --- | --- | | Model | Chosen by which tool you installed | Picked from an agent dropdown per task | Gone — swapping is one click | | Provider CLI | N/A | Install Codex CLI / Claude, set the path in settings | Low — standard, replaceable | | Approvals | Per-tool, ad hoc | Configurable approval settings for CLI sessions | Medium — lives in GitHub settings | | Hooks + MCP | Wired per project | Managed in 'Agent Customizations' for CLI sessions | High — your automations bind here | | Custom instructions | Per-tool prompt files | GitHub-side customizations | High — your team's conventions live here | GitHub spent this month turning the [coding agent](/topics/coding-agents) into a dropdown. Under the "Agent HQ" banner, Copilot now lets you run **Claude or Codex — alongside Copilot's own agent — inside VS Code, the JetBrains IDEs, and Copilot CLI**, chosen from an agent picker per task rather than wired in when you picked your tool ([GitHub](https://github.blog/news-insights/company-news/pick-your-agent-use-claude-and-codex-on-agent-hq/)). If you build software with one, the practical question isn't "which is best" — it's "what does a swappable model actually free me from, and what still holds me?" Short answer, up front: **the model is now genuinely portable, and that kills the cheapest kind of lock-in. But the lock-in moved one layer up — into the harness you configure around the model — and that layer is the one your team actually depends on.** What shipped The rollout landed in pieces over June and July. Claude arrived as an agent provider in the JetBrains IDEs in a June preview ([changelog](https://github.blog/changelog/2026-06-22-new-features-and-claude-as-agent-provider-preview-in-jetbrains-ides/)); Codex followed on **July 7** as a selectable provider ([changelog](https://github.blog/changelog/2026-07-07-codex-as-agent-provider-and-agentic-enhancements-in-jetbrains-ides/)). The mechanics are deliberately boring: **install the provider's CLI on your machine, point Copilot at its path in settings, and pick the agent from the session picker.** No re-tooling, no new editor. Two quieter changes in the same wave matter more than the headline. First, **approval settings are now configurable for Copilot CLI sessions**, and **hooks and [MCP servers](/topics/mcp) can be managed directly in "Agent Customizations"** for those sessions — the [guardrails](/topics/agent-security) and the tool surface are becoming first-class config. Second, GitHub expanded **bring-your-own-key (BYOK)** in the JetBrains IDEs ([changelog](https://github.blog/changelog/2026-07-14-github-copilot-for-jetbrains-expands-byok-capabilities/)), so the model choice extends to your own provider credentials. Alongside it, **agentic browser tools went generally available in VS Code** — agents can navigate, screenshot, and validate a running web app in-editor ([changelog](https://github.blog/changelog/2026-07-08-github-copilot-in-visual-studio-code-june-2026-releases/)). The lock-in didn't leave — it moved up a layer The instinct is to read "pick your agent" as the end of [vendor lock-in](/topics/model-selection). It isn't, and it's worth being precise about why, because the mistake costs you later. Swapping the *model* was always the shallow layer. It's the same lesson we drew in [Provider-Agnostic AI Agents: the lock-in isn't where you think](/posts/provider-agnostic-ai-agents.html) — a one-line model swap is true for a chatbot and misleading for an agent, because the behavior you actually tuned lives above the model call. Agent HQ makes the shallow layer trivially portable, which is real and useful. But look at what it simultaneously pulls *into GitHub's surface*: your **approval rules**, your **hooks**, your **MCP server list**, your **custom instructions**. That's the harness — and the harness is what your team builds muscle memory and automations against. A coding agent's value on your codebase is 20% the model and 80% the scaffolding: which files it's allowed to touch, what it must ask before running, which internal tools it can call, the conventions baked into its instructions. When that scaffolding lives only in a vendor's settings pane, "the model is a dropdown" is cold comfort — you can change the engine, but the chassis is bolted to one garage. The founder move Two habits keep the freedom real: - **Treat the model as swappable, and prove it monthly.** The whole point of a dropdown is that benchmarking Claude vs Codex is now a click, not a migration. So actually do it — on your real repo, on the tasks you run (a multi-file refactor, a flaky-test fix, a dependency migration), scored on **cost per completed task**, not a public leaderboard. We walk through why one headline number lies in [How to Benchmark LLM Inference](/posts/how-to-benchmark-llm-inference.html); the same discipline applies to agents. Cheaper-per-token loses to fewer-retries every time. - **Keep the harness in version control you own.** Put your hooks, MCP config, and custom instructions in files in your repo and treat GitHub's Agent Customizations as a place you *load* them into — not the only place they exist. That's the difference between a model choice that's portable and a workflow that's captured. If you're weighing tools more broadly, [Cursor vs Windsurf vs GitHub Copilot vs Claude Code](/posts/cursor-vs-windsurf-vs-github-copilot-vs-claude-code.html) frames the four as architectural postures — and the posture, not the model, is what you're really choosing. Agent HQ is a genuinely good change: it makes the expensive experiment cheap. Just don't mistake a portable engine for a portable car. Own the chassis. ## FAQ ### Can I really switch between Claude and Codex inside Copilot now? Yes. GitHub shipped Claude and Codex as selectable agent providers across the JetBrains IDEs, VS Code, and Copilot CLI under the 'Agent HQ' banner. You install the provider's CLI on your machine, point Copilot at it in settings, and choose the agent from the picker before a session. The model is a per-task choice, not a build-time commitment. ### So does this end vendor lock-in for coding agents? No — it ends the cheapest layer of it. Swapping the model no longer means swapping tools. But the harness you build around the model — approval rules, hooks, the MCP servers your agent can call, your custom instructions — now lives in GitHub's Agent Customizations, and that is the layer your team's workflows actually depend on. The cage moved up, it didn't open. ### Which should a solo founder pick, Claude or Codex? Neither answer is stable, which is the point of a dropdown. Benchmark both on your real repository on the tasks you actually run — a multi-file refactor, a flaky-test fix, a migration — and compare on cost per completed task, not vibes or a leaderboard. The value of Agent HQ is that this benchmark is now a dropdown change instead of a tool migration, so run it monthly. ### What should I keep under my own control? The harness. Put your hooks, MCP server config, and custom instructions in files in your repo, checked into version control you own, and treat GitHub's settings pane as a place you load them into — not the only place they exist. That keeps the layer that actually locks you in portable if you ever leave. ### What else shipped alongside this? GitHub also made agentic browser tools generally available in VS Code — agents can navigate pages, capture screenshots, and validate a running web app in-editor — and expanded bring-your-own-key (BYOK) support in the JetBrains IDEs, so the model choice extends to your own provider credentials.
