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 contract and adds Docker-based integration tests with elevated sandbox options for coding; the coding and argument-hints examples touch isolation, grading boundaries, and API-key-backed file staging.

Overview
Introduces first-class example environments under environments/ (blank, coding, cua, argument-hints) and shifts onboarding from remote GitHub presets to hud init --template copying those projects (default coding for named non-interactive init; --preset kept as an alias). Docs and README are updated accordingly; the cookbooks/codex-coding sample is removed in favor of the full coding environment.

The coding example is a SWE-bench Lite–style repo workspace with hidden JUnit grading, flask.bundle, and isolation-focused Docker setup; argument-hints demonstrates console x-hud-hint controls plus HUD API data-file staging and rubric grading.

CI gains a templates matrix job: hud init each template against the checkout SDK wheel, optional lint/tests, Docker build/run, health check on port 8765, and template-specific hud task start/grade smoke tests (extra seccomp/AppArmor settings for coding). Workflow contents: read permissions are set; root .gitignore stops ignoring environments/ so examples ship in-repo.
