A workbench for the coding agents you already use.

Features

1. Or the same agent, as a conversation.

   Open it Integrated for permission cards, plans and diffs. The native CLI still does the work.

   Two tabs can submit the same cart. Find the race and fix it.

   I’ll start with the checkout controller and the order service.

   Used2 Read

   The cart is only locked after the payment intent exists, so two requests can both pass the stock check.

2. It starts helpers.

   Agents start helpers, message them and wait for their reports. Each one nests under the agent that started it.

3. Your machines, working together.

   Pair Patterm on your dev box and your desktop. Their agents can message each other and wait for replies, and you see every agent on both machines in one window.

   Checkout tests pass. I’ll start helpers for regression tests and the payment retries.

   While they work, I’ll ask the benchmark agent on the desktop to measure the fix under load.

4. It can draw you a chart.

   Integrated agents can answer with charts, tables, diagrams and choices. They send the numbers, and Patterm draws them to match the app.

5. When it needs you, you’ll know.

   Permission prompts, questions and finished work land in one list, and notifications can follow you to your phone.

   NotificationsMark all read

   Notifications are kept for 30 days after they are read.

6. Or ask what’s waiting.

   A Codex-powered assistant keeps track of every agent in every project. Talk to it by text or by voice.

   Assistant

   What’s waiting on me?

   Two things in storefront:

   • Audit payment retries wants to run a migration.
   • Upgrade to Vite 8 is ready to close. Build and tests pass.

   Write regression tests already reported: six tests, all passing.

7. You review before anything lands.

   Give a helper its own worktree, then read its changes file by file. Patterm never commits for you.

   Two tabs can submit the same cart. Find the race and fix it.

   I’ll start with the checkout controller and the order service.

   The cart is only locked after the payment intent exists, so two requests can both pass the stock check. I moved the lock into a transaction around the stock check.

10. Know what’s left before you start.

    Usage shows what’s left of your Claude Code and Codex 5-hour and weekly limits, when each resets, and the tokens you’ve used.

11. Work that carries on while you’re away.

    Routines start an agent on a schedule with your instructions, and notify you when it reports.

    Nightly dependency check

    Run every week on MoTuWeThFrSaSu02:00

    Start Codex with default preset in storefront and ask it to:

    Check for outdated dependencies since {{last_run_at}}, upgrade the safe ones in a worktree and add a todo for anything risky.

    Insert {{date}}{{weekday}}{{since}}{{last_run_at}}

    When it reports, notify me
