tools-agentbox

Devcontainer features, templates, and pre-built Docker images for Power Platform / Dataverse developers.

Don't run coding agents directly on your own workstation. They execute arbitrary commands, which is a real security exposure, and heavy agent workloads wear on a machine over time. Run them in one of the isolated environments below instead — see GitHub's own take on why: About cloud and local sandboxes.

Choose your environment

1. GitHub Codespaces

New project — create .devcontainer/devcontainer.json:

{
  "name": "Power Platform",
  "image": "ghcr.io/talxis/tools-agentbox/image:latest",
  "customizations": {
    "codespaces": {
      "openFiles": ["README.md"]
    }
  },
  "hostRequirements": {
    "cpus": 2,
    "memory": "8gb"
  },
  "postCreateCommand": "curl -fsSL --max-time 20 https://talxis.com/agentbox-harness | timeout 90 bash || true"
}

Already have a devcontainer.json? Point image at ghcr.io/talxis/tools-agentbox/image:latest and add that same postCreateCommand line — it's easy to end up with a working toolchain but no Skills/MCP registration if this step gets skipped, since nothing it does is baked into the image itself. It registers the TALXIS/skills plugin (Skills + the txc MCP server) with whichever of Claude Code / GitHub Copilot is present — omit it if you don't want that.

Or build your own devcontainer.json from individual features listed in devcontainer.features.json.

2. GitHub Copilot cloud sandbox

Copilot's cloud agent environment doesn't use devcontainer.json — customize it with .github/workflows/copilot-setup-steps.yml instead.

3. Claude Code cloud environment

Create an org-shared Claude Code cloud environment with:

• Setup script:

  curl -fsSL https://talxis.com/agentbox-setup \
    -o /tmp/agentbox-setup.sh && AGENTBOX_HARNESS=claude bash /tmp/agentbox-setup.sh || echo "agentbox setup failed to download or run" >&2

• Environment variables: DOTNET_ROOT=/usr/local/dotnet/current, CLAUDE_CODE_PLUGIN_SEED_DIR=/usr/local/claude-plugin-seed
• Network access: Custom, with the defaults included, plus cli.github.com and talxis.com (the setup script's short links redirect through it to github.com/ghraw, which is already on the default list)

This installs the Feature list from devcontainer.features.json directly on the VM, and registers the TALXIS/skills plugin (Skills + the txc MCP server) with Claude Code. No changes needed in individual repos.

To keep txc and the Dataverse templates current between setup script runs, merge the hooks from src/container/claude-code/session-start-hook.json into Admin Settings > Claude Code > Managed settings.
