Summary

  • add source-tree coding and computer-use example environments
  • make hud init copy a selected bundled example without remote downloads
  • use a real SWE-bench Lite task with a self-contained repository bundle and hidden JUnit grading for the coding example
  • demonstrate Chromium, Xvfb, x11vnc, noVNC, and the HUD server under one supervisor in the computer-use example
  • document the new initialization flow, exercise both examples in CI, and exclude environments/ from distributions

Validation

  • uv run pytest hud/cli/tests/test_init.py -q — 13 passed
  • uv run pytest tests -q in environments/coding — 15 passed
  • uv run pytest tests -q in environments/cua — 5 passed
  • uv run ruff check hud/cli environments
  • uv run ruff format --check hud/cli environments

Note

Medium Risk
Changes the public hud init default and ships a sandbox/isolation-heavy coding environment plus Docker/seccomp CI. Behavior and security of agent workspaces matter, but this is examples and scaffolding rather than core auth.

Overview
hud init now copies a complete example from the SDK (coding, cua, or blank) instead of downloading many GitHub presets. Named non-interactive runs default to coding; --template/-t replace --preset (still accepted as an alias). Installed releases fetch the matching SDK tag so the example matches the installed version.

The coding example is a SWE-bench-style repo workspace: isolated ssh sandbox, hidden JUnit tests via JUnitGrader, and bundled Flask tasks. blank is a minimal prompt/grade scaffold. Docs, cookbooks, and CI now treat these as the starting points; the old cookbooks/codex-coding agent sample is removed.

CI adds a templates job that inits each example against the checkout wheel, lints/tests when present, builds the image, and runs a short hud task lifecycle.
