What is ShadowHarness?

A shared home
for your AI work.

ShadowHarness is a Windows app for using AI tools such as Claude and Codex, from different providers and models, at the same time. Work with conversations and files side by side. All past memories form Sidera Memory and carry forward into the next task. Send instructions and photos from Android with Shadow Link.

WORKSPACE

A shared workspace.
Room to grow.

CLIs launched in Shadow start from a shared workspace. Describe what you want to do and begin experimenting or researching there. As the work grows, it is organized into a project with its change history tracked.

Temporary files outside projects are kept in scratch and automatically deleted once more than 14 days have passed since their last update. Shadow notifies you if files are left at the workspace root.

Describe the project to pick up the work

Talk about the project and Sidera recalls relevant memories. Follow the earlier context and working location to continue where you left off.

Keep AI conversations, files, the editor, and previews together to check the actual result as you work.

GABURU BOARD

AI panes collaborate.
Through Gaburu Board.

AI conversation panes can use Gaburu Board to divide work autonomously and request tasks from one another. An AI implementing a change can ask another AI to research or review it, then use the returned findings to continue the work.

Gaburu Board shares requests, assigned panes, acceptance and completion status, and results. AIs from different providers and models can collaborate this way.

Example: an AI requests a review from another AI

Implementing AIReviewing AI

Review this change and report any issues.

The implementing AI posts a request to Gaburu Board. Another pane reviews it and returns findings, which the implementing AI can use to continue making changes.

Example: share a requirement with every pane

Working AIAll running AIs

Tell every pane: “Keep the API contract unchanged.”

Share requirements and specification changes through Gaburu Board so each pane can work from the same instructions.

SIDERA MEMORY

Your next conversation.
With a memory.

ShadowHarness includes Sidera Memory and automatic recall. It forms memories from past conversations and automatically supplies relevant context to the AI working with you. Carry decisions and their reasons into the next task, even after closing a conversation or changing models.

Keep the decision and the reasoning

Trace the approach you chose, why it changed, and what remains to be done, without explaining the entire history again.

Return to the original conversation

Check the conversation behind a recalled memory. Records from connected devices accumulate in the same memory.

The SIDERA store sells one-off batch processing of collected logs, such as a project history. This service can be purchased without ShadowHarness. Store prices cover a single batch job, separately from ShadowHarness pricing.

SHADOWHARNESS GUIDE

Start working with Shadow

Enter your email on the registration page and verify the same Google account using the emailed link. When setup is complete, you will receive download links for Windows and Android by email.

Launch a CLI and start a task

  1. Click ＋CLI at the top of the window, choose a provider and CLI, then click “Launch this CLI.” Follow that CLI’s sign-in instructions if prompted.
  2. Type what you want to create or investigate in the CLI conversation. To open another CLI, use ＋CLI again.
  3. Click “Arrange” at the top of the window to position the open conversations and file views together.

Work in the shared workspace and grow your project

  1. CLIs launched in Shadow work in the shared workspace by default. Describe what you want to create or investigate and get started, without first specifying a folder.
  2. As an experiment becomes ongoing work, the CLI organizes it into a project and tracks its change history with Git.
  3. One-off work outside projects is kept in scratch. Files are automatically deleted once more than 14 days have passed since their last update. If files are left at the workspace root, Shadow notifies you and offers to organize them.
  4. To resume earlier work, describe the project. Sidera recalls relevant memories so you can trace its history and working location even when you do not remember the folder path.
  5. Open the work in EXPLORER and click a file to view it in PREVIEW. Keep the actual result beside the AI conversation as you continue.

Request work from another CLI or announce to all

  1. Launch the CLI that should receive the task and check the name in its title.
  2. In your current CLI conversation, type “Ask Claude 2 to test the login screen.” Replace “Claude 2” with the recipient’s displayed name.
  3. For a shared instruction, type “Announce to all CLIs: Keep the API contract unchanged” in the conversation.
  4. Open Window → Guide. Right-click the binder-clip mascot sitting above the guide panel and choose “Switch view: Guide ⇄ Board.”
  5. On the board, find the task under Open, Accepted, or Closed, then click its card to read the report.

Start using Sidera Memory

  1. Open Window → SIDERA MEMORY and read the data handling and consent terms.
  2. Click “Agree and Start” to check the session count and upload size, then click “Agree and Start” again to confirm. The first memory build’s progress appears in the same view.
  3. If the CLI toolbar shows “Inject✕,” click it to switch to “Inject.” Continue working in the conversation; memories relevant to your input are delivered to the AI.

Send instructions and attachments from your phone

  1. On your PC, open Shadow → Link a phone (QR), then click “Register a phone (QR)” to display the code.
  2. Sign in to Shadow Link for Android with the same Google account as your PC, then scan the QR code on the PC.
  3. Open a CLI from the list on your phone, type an instruction in the message field, and send it. You can attach photos and files too.
