testsAndMisc

Mixed-language monorepo: Python packages, Bash automation, and several apps.

Repository Layout

Path	Description
python_pkg/	Python packages — every .py in the repo belongs here or in an allowlisted dir
meta/	Repo-wide tooling: pyproject.toml, requirements.txt, run.sh, lint_python.sh, .fvmrc, scripts/
linux_configuration/	Arch setup, i3 config, system maintenance, and the tracked git hooks
phone_focus_mode/	GPS-based Android focus enforcer (Bash, ADB, Magisk)
billsplit/	Receipt bill-splitting Flutter app (Dart)
bottles/	Small standalone project
docs/	Reference docs; docs/superpowers/ holds AI workflow artifacts
third_party/	Vendored upstream skills/agents

Root pyproject.toml, requirements.txt, run.sh, lint_python.sh and .fvmrc are symlinks into meta/ — edit the files in meta/, not the symlinks.

Extracted to their own repos: steam-backlog-enforcer, screen-locker, diet-guard, wake-alarm, dufs-cloud, build-your-x (lives at ~/build_your_x), reverse-survivors, kcd2-dice-solver (lives at ~/kcd2-dice-solver), focus-owner, mtk-root, system-maintenance (lives at ~/system-maintenance), android-guardian (lives at ~/android-guardian). Archived work: testsAndMisc-archive.

Adding a Flutter app

billsplit/ is currently the only one, and the only place binaries are committed. To add another, repeat both halves or the icons fail silently:

1. Add the icon globs to .binary-allowlist.
2. Add matching ! overrides at the end of .gitignore — an ignored file fails silently on git add rather than erroring.

Icons come from the shared generator in python_pkg/app_icons/. Dart style is gated by CI only (.github/workflows/billsplit-ci.yml), not by a local hook. Keep app dirs free of Python: the check-python-location hook requires every .py to sit under python_pkg/ (or linux_configuration/, phone_focus_mode/, meta/scripts/). billsplit/'s coverage gate therefore lives at python_pkg/billsplit_coverage/.

Git Workflow

Work directly on main; commit and push straight there.

core.hooksPath points at the tracked linux_configuration/.githooks/, so hooks travel with the repo. .git/hooks/ is unused — never run pre-commit install.

• pre-commit: shfmt + shellcheck + jscpd (fails above 2% duplication), then pre-commit run --hook-stage pre-commit.
• pre-push: pre-commit run --hook-stage pre-push — prettier and ci-mirror. ci-mirror runs a clean-venv install, pre-commit run over all files, and pytest for changed packages.

Bootstrap a clone or new machine:

./meta/scripts/install_hooks.sh          # wire hooks + install missing tools
./meta/scripts/install_hooks.sh --check  # verify only; exit 1 if incomplete

Both hooks fail closed: every external binary is verified each run and auto-installed via pacman where possible. A missing tool aborts the commit — it never means "skip the check". Extend REQUIRED_TOOLS in linux_configuration/.githooks/lib/common.sh when adding a language: system hook. common.sh also warns when local shellcheck/prettier/shfmt/zsh drift from the versions pinned in .github/workflows/pre-commit.yml.

Development Workflow

• Do NOT run tests unless instructed, or before committing.
• If tests fail on the same issue twice in a row, STOP and ask.
• Confirm a change works by running the program and inspecting output — not by running tests. Then ask the user to confirm the behaviour.
• Fix coverage gaps; do not ignore them.

AI evidence (enforced)

Every commit touching code needs an evidence artifact:

1. Copy docs/superpowers/evidence/template.json → docs/superpowers/evidence/<task-slug>-<date>.json.
2. Fill in intent, scope, changes, verification, risks, rollback.
3. Stage it with the code.

validate_evidence.py rejects empty verification[] and the phrases "should work", "probably fine", "seems right".

Staging ≥4 code files additionally requires a fresh docs/superpowers/contracts/*.json in the same commit.

Deletions in docs/superpowers/sessions/* abort the commit (append-only).

Code Conventions

Anything already enforced by a hook is omitted here — run pre-commit run --all-files and read .pre-commit-config.yaml for the complete list. What follows is what a linter cannot check.

Python

• from __future__ import annotations for forward references.
• Prefix private functions/modules with _ (_smart_plug.py, _process_game_event).
• Mock external calls in tests; never hit real APIs or the filesystem.
• For branch coverage: prefer an explicit while True with try/except StopIteration over for when iterator exhaustion needs covering, and mock threads/subprocesses to keep tests fast.

Full linting/coverage configuration lives in meta/pyproject.toml (ruff select = ["ALL"], mypy, pylint enable = "all", coverage fail_under = 100 with branch coverage). Note the mypy hook disables a number of error codes, so it is weaker than the strict = true in the config.

Shell

• set -euo pipefail in every script.
• Prefer /proc, /sys and bash builtins over $(...) in hot paths — see the efficient-polling-scripts skill. The no-polling-antipatterns hook only inspects functions named *_loop, *_daemon or poll*, so a fork storm elsewhere passes clean.
• Use jq/yq for JSON/YAML, not grep/awk.

Key Files

• meta/pyproject.toml — all Python tool configs
• .pre-commit-config.yaml — hook definitions
• linux_configuration/.githooks/ — the tracked git hooks
• meta/requirements.txt — runtime + dev dependencies
• docs/superpowers/evidence/template.json — evidence template
• .github/workflows/ — pre-commit, python-tests, shell-tests, and one CI workflow per app
