When the Claude window runs out: my take on T3 Code
Audio Narration
T3 Code addresses the frustration of hitting Claude’s five-hour usage limit during focused work. Rather than replacing coding agents, it provides a single desktop interface for tools such as Claude Code, Codex, Cursor, Grok Build, OpenCode, and Antigravity, with users signing in through their own accounts. Each thread remains tied to its original provider, so an unfinished Claude conversation cannot be transferred directly to Codex. However, the surrounding workspace, project, and workflow stay in one app. When a limit is reached, T3 Code identifies the restriction and reset time, allowing the user to start a new thread with another provider and quickly restate the task. The app is free and does not resell or mark up tokens, aligning its incentives with users who want to avoid unnecessary calls. Its MIT license, self-hosting support, public codebase, and more than 21,000 GitHub stars are especially important because it handles provider credentials and repository access. Although founder Theo frequently promotes the product, its transparency makes those claims easier to verify. The Linux desktop app remains young and occasional releases cause problems, but steady improvements and its ability to coordinate separate agents make it a practical solution for maintaining momentum.
The five-hour wall
Anyone on a Claude subscription knows the moment. You are deep in a task, the plan is working, and the usage window closes. The work stops. Not because the problem got hard, but because a clock ran out.
For a long time my answer was to open another tool, paste in what I could remember of the context, and hope. That is a bad answer. Context is the expensive part.
What actually happens when Claude runs out
T3 Code is a desktop app that sits in front of your coding agents instead of replacing them. Codex, Claude Code, Cursor, Grok Build, OpenCode and Antigravity all plug in, and you sign in to each one with your own account.
You pick the provider when you start a thread, and that thread keeps it. There is no handing a half-finished Claude conversation over to Codex. What you get instead is that everything around the conversation stays put. Same app, same project, same place I was working. When the limit hits, the thread tells me which one I reached and when it resets, and I open a new thread on Codex and describe the task again. Re-explaining costs me a minute. Leaving for a different tool used to cost the afternoon.
It does not resell your tokens
T3 Code is free and you bring your own subscriptions. It does not sit in the middle and mark up API access.
I like this more than I expected to. A tool that resells tokens has a reason to want you making more calls. This one does not. It has no idea what my Claude plan costs and no way to profit from me burning through it faster. The incentives point the same direction as mine.
Open source is doing real work here
MIT licensed, self-hostable, and you can fork it. Over 21,000 stars on GitHub.
For most apps I treat open source as a nice bonus. Here it counts for more. This thing holds credentials for every AI provider I use and reads every repository I point it at. Being able to check what it does with them, or run my own build, is not a philosophical preference. It is the reason I was willing to install it at all.
Yes, Theo promotes his own tool
I found T3 Code through Theo on YouTube, where he plugs it often. That is worth saying out loud.
It bothers me less than it might, because the code is public. A closed tool with a loud founder asks for trust. An MIT-licensed one asks you to go look. I went and looked.
Slowly getting better
I run the desktop app on Linux, and I have used it long enough to watch it grow. Features land steadily, rough edges get sanded down, and the version I use today is better in ways I notice every week.
It is still a young product and it acts like one. Some releases break things. But the core idea holds up. My agents are separate tools with separate limits, and something has to sit above them and keep the work moving when one of them stops. Right now this is the best answer I have found.
Trying out autonomous agents
Sandcastle is Matt Pocock’s workflow for running Claude Code unattended inside a Docker container. It assigns the agent a GitHub issue in a git worktree, then merges the resulting commits back into the user’s branch. Its init command quickly scaffolds the infrastructure, but useful results still depend on supplying clear, focused tickets. Wayfinder fills that planning gap by breaking an idea that is too large for one session into a map issue and smaller decision tickets. Each ticket addresses a single unresolved question rather than a build segment, producing the self-contained, labeled issues Sandcastle needs. Without this map, vague issues led to equally vague pull requests. Before queueing work, the author uses a grilling skill to challenge assumptions and force difficult decisions. Resolving uncertainty early prevents the agent from making costly guesses during unattended runs. For secrets, the author replaces a plaintext .env file with Varlock and a committed .env.schema. Values are resolved through Doppler and exposed only through process.env during execution, although each secret must still be explicitly forwarded into the container configuration. The author would use the setup again but stresses that ticket quality remains decisive. Every diff is still reviewed, tasks stay tightly scoped, and fully unattended overnight operation remains a future goal.

Decisions, not code: a month with Matt Pocock's agent skills
AI agents can generate code quickly, but the real bottleneck is deciding what should be built. Matt Pocock’s skills repository addresses this through tools that clarify requirements before implementation. “Grill me” conducts a persistent interview, mapping an idea into a design tree and identifying the current frontier of answerable questions. It presents numbered questions alongside recommended answers, turning an overwhelming list into a practical review. It researches factual questions itself, leaving genuine decisions to the user, and continues until no assumptions remain. “Grill me with docs” combines this process with domain modeling, recording decisions as ADRs and maintaining a glossary. This preserves reasoning beyond the agent’s context window and gives important terms stable meanings, reducing inconsistency in later work. “Wayfinder” supports projects spanning multiple sessions. It creates a map issue with linked decision tickets, dependencies, and assignment rules that prevent parallel agents from colliding. Tickets resolve decisions rather than represent implementation slices, while the map remains an index. These tools lead to more planning and less rewriting, but they add unnecessary overhead for small tasks. Grilling is most useful for work likely to continue into the following week, while Wayfinder suits only larger efforts requiring a disciplined issue tracker.
