AGILAB Installer Skill

Use this skill when working on:

• install.sh / install.ps1 (root installer)
• src/agilab/install_apps.sh / src/agilab/install_apps.ps1 (apps/pages installer)
• src/agilab/apps/install.py (app install entry)
• Data seeding / dataset archives / post-install hooks

Golden Rules

• Use uv --preview-features extra-build-dependencies … for Python entrypoints.
• Do not add silent fallbacks (detect missing capabilities and raise actionable errors).
• Keep installs idempotent: rerunning should not wipe user data or re-download unnecessarily.

Common Commands

• Full install (macOS/Linux):
  • ./install.sh --non-interactive --cluster-ssh-credentials user:pass --apps-repository /path/to/apps-repo --install-apps --test-apps
• Apps/pages install only:
  • cd src/agilab && ./install_apps.sh --test-apps

Debugging Patterns

• “Does not appear to be a Python project”

  • You are installing a directory without pyproject.toml/setup.py.
  • Ensure the installer runs uv pip install -e . from the repo root.

• App install fails with missing worker/manager

  • Validate both manifests exist:
    • manager: .../<app>_project/pyproject.toml
    • worker: .../<app>_project/src/<app>_worker/pyproject.toml

• Dataset extraction wipes seeded files

  • Avoid mtime heuristics on extracted files; use a stamp file tied to the archive.
  • Prefer linking to shared datasets rather than copying to each app.

Data Dependencies Between Apps

Some apps depend on outputs of others (e.g. LinkSim needs satellite trajectories). Preferred approach:

• Install/seed the producing app first.
• Reuse outputs via symlink/junction into the dependent dataset folder to avoid duplication.
