BUILT FROM REAL DEVELOPMENT WORK

Opening another agent is easy.
Keeping the work aligned is harder.

The API is in one terminal. The frontend is in another. One agent implements, another reviews. You repeat the same specification, search for the last response and try to remember who is waiting for whom. PrumoGrid was built to organize this part of AI-assisted development.

More context in the project. Less work passing context between windows.

01 / INSIDE THE APP

Your terminal is still yours.

PrumoGrid adds space and context to the work you already do in the command line. Start with a grid. Add structure when you need it.

API, frontend and infrastructure in one workspace.Actual 0.5.4 interface. Demo projects; interface shown in Portuguese.
01 /

Less window switching.

Follow multiple projects, each with its own folder and terminals. Filter one project or see the whole workspace in All projects. Keep API, frontend and infrastructure work organized.

02 /

Pick up where you left off.

In persistent mode, terminals stay active when you close the window. After restarting Windows, resume identified Claude Code and Codex conversations through their CLIs.

03 /

Know what was verified.

An agent response and a passing command are different outcomes. Define a verification criterion and follow its result in the workflow.

04 /

Give each agent context.

Organize rules, roles and routines. Separate work using worktrees, and follow history and usage reported by supported CLIs.

02 / FROM PROMPT TO RESULT

Your way of working.
Room to grow.

You do not need an automation to open a terminal. Move from a simple session to multi-agent workflows at your own pace.

01

Open your project

Add your working folder. Terminals open in that context.

02

Choose your terminal

Use PowerShell, CMD, WSL or Git Bash. Start an installed, authenticated CLI such as Claude Code or Codex.

03

Follow up and continue

Work directly in the terminal or create steps. Check pending work, verify results and continue in the same session.

AN EXAMPLE WORKFLOW

  1. ImplementA task for your agent
  2. VerifyYour test command
  3. ReviewThe next step

You define the steps and criteria. PrumoGrid tracks execution.

IN PRACTICE

A workflow you can follow.

An example: implement a change, verify the result and hand it over for review. See where each part happens in the app.

01 /

Describe what needs to be done.

In New execution, write the task and choose its project and agent. When the result needs to pass a test, enable command verification.

  1. Open New execution → Task with agent.
  2. Write the request and check its executor.
  3. Define a verification command when appropriate.

↳ The request is connected to the project, terminal and completion criterion.

02 /

Stop repeating the same specification.

Define shared instructions and choose their scope: one project, all projects or a role. PrumoGrid organizes content in the files supported CLIs read, such as AGENTS.md and CLAUDE.md.

  1. Open Rules and create a new rule.
  2. Write the instruction and choose its scope.
  3. Check delivery and whether the agent needs to read it again.

↳ A common foundation for different agents, with room for specific instructions.

Actual 0.5.4 interface in Portuguese. Demo rule.
03 /

Hand work over to the next step.

Turn a recurring sequence into a routine. One step implements, another reviews and another tests. Choose executors and follow what is running, completed or waiting on a dependency.

  1. In New execution, select Use routine.
  2. Choose a sequence and describe the task.
  3. Review the project and executors before starting.

↳ The sequence stays visible. You do not have to rebuild it for every task.

04 /

The next task can use the context you already built.

With an open conversation, use Continue in this session to create another step in the same terminal. The conversation stays in the CLI; model and permissions follow the existing session.

  1. Check the previous step’s result.
  2. Choose Continue in this session.
  3. Write the next instruction and confirm.

↳ Continue your work with the context you already have.

YOUR TERMINAL, YOUR TOOLS

Your harness still
has a place here.

Already have scripts, versioned prompts or your own layer for calling agents? Run your commands in PrumoGrid terminals. Use project organization and add rules and workflows as you need them.

Running your own command remains available. Features such as resuming, notifications and metrics depend on each CLI integration.

CLI options are configurable; empty fields preserve their defaults.

EXTEND IT YOURSELF

Your workflow.
Your own plugins.

Create commands and open project terminals with a plugin built in your own repository. The guide includes complete files, a standalone packager and an installable example.

WHERE PRUMOGRID STARTED

Orchestrating multiple projects and coding agents

By Carlos Alvarenga

About the author

I’m a software architect with 30 years of experience in enterprise systems, including 18 years at MXM Sistemas, where I currently work as an architect.

I hold an MBA in Artificial Intelligence and Big Data from USP/ICMC, with research into standardized code generation. My focus is applying AI to enterprise systems with governance, security and tangible results, preserving what already works.

I want to make technology more accessible, help train new developers and turn ideas into working solutions.

I tried several tools, but something was always missing.

I usually split a project into smaller projects, and I often work on several projects at once.

I wanted a single place to interact with multiple terminals, orchestrate coding agents in stages, get notified when something needed my attention and track what had already been done. All in one tool.

PrumoGrid grew out of that need, initially as a tool for my own work. Gradually, I turned those needs into specifications, validating and testing ways to bring terminals, projects, agents and pending work into the same workspace. It took about three months of work in my spare time to reach this pre-alpha version.

BUILT WITH THREE CONTRIBUTORS

Me, Claude Code and Codex.

I also wanted to see what it would take to build a technical tool for programming. In this project, that was only viable with frontier models: with smaller models, the cost of reworking, fixing and reviewing outweighed the benefits.

I focused on specifications, validation and testing. I used Claude Code and Codex in alternating development and adversarial review roles: while one implemented, the other looked for flaws, challenged decisions and examined what could break. Then their roles switched.

Before you install

  • Windows 10 1809+ or Windows 11, 64-bit.
  • Node.js is not required to run the app.
  • For agents, install and authenticate their CLIs. Provider accounts and costs are separate.
  • Git is required for code review and worktree features.

In this release / 0.5.4

  • Resume identified Claude Code and Codex conversations after a restart.
  • Native plugins with installation, activation and commands.
  • Confirmation when closing a project with terminals.
Verify installer integrity

Run the command below in PowerShell and compare its result with the published SHA-256. The hash verifies the file; it does not replace a digital signature.

04 / THE DETAILS

Before your first prompt.

Security and privacy ↗
Do I need to use an AI agent?

No. PrumoGrid also works as a terminal grid organized by project. Agents are optional and must be installed and authenticated on your computer.

What happens when I close the window?

In persistent mode, terminals keep running in the local service and reconnect when you reopen. Parts of step coordination need the window to stay open. Restarting Windows stops the processes; resuming a conversation depends on the CLI, account and available history.

Is the source code available?

Source code is not available yet. Future publication is planned, with no announced date. For now, this site offers only the installer, under Apache 2.0.

Does the app run locally?

Yes. PrumoGrid organizes terminals and data on your computer without requiring its own account. Agents and commands you run may use the internet and send data to the services you choose.

How do I install a plugin?

Open Tools → Extensions, install a .prumoplugin file, review its information and permissions, enable it and run its commands. Plugins run code with your account privileges: only install plugins you trust. VS Code/VSIX extensions are not supported.

How do I start after installation?

Open PrumoGrid, click add projects and select a folder. Open a terminal and work as usual. To use a CLI, run its command. When you want to organize tasks, use New execution.

What data does this website collect?

This page includes no forms, trackers, analytics cookies or third-party scripts. Fonts and images are served with the site. Hosting infrastructure may process technical access data, such as IP addresses and request logs, to deliver and protect the service.
