CI caught what this machine could not: the hook died with "No module named 'screen_locker'". The package is pip-installed here (editable, pointing at this checkout), so running the script by path found it anyway; a fresh checkout has no install, and `python3 scripts/x.py` puts only `scripts/` on sys.path. `python3 -m scripts.verify_screen_fits` puts the repo root there instead, which is the checkout in CI and here alike -- verified in a throwaway worktree, where the module now resolves to the worktree's own package rather than the installed one. The xvfb re-exec runs the same way, with an explicit cwd so the child does not depend on where the parent was invoked from. pylint had the same blind spot for the same reason: it infers sys.path from the files it is handed, so this script resolved its imports only when a package file happened to be in the same batch -- passing or failing by what else was staged. An init-hook puts the repo root on the path unconditionally.

screen-locker
Tkinter/systemd screen locker with workout tracking, sick-day management, and wake-alarm integration. It enforces a workout cadence by locking the screen until a RunnerUp-verified (or explicitly justified) workout is logged.
MCP server (Claude Code integration)
screen-locker exposes a read-only MCP server (screen_locker._mcp) so
Claude Code and its subagents can query workout compliance and the
lock-decision state through typed tools — without shelling out to the
screen-locker-status CLI or opening the Tk window.
- Read-only tools:
get_status(full status snapshot),get_summary(one-line i3blocks summary +ok/warn/lockstate word),explain_lock(why the screen is / isn't locked right now),get_flags(the individual boolean lock-decision predicates for today). - There are no write/action tools, by design. Nothing here logs a workout or mutates state — workouts are logged only from RunnerUp-verified TCX data, never from a caller's claim. No tool exposes the sync token or any HMAC key.
The mcp SDK is an optional dependency (pip install -e '.[mcp]'), kept out of
the CLI/systemd system-python path. One-time setup of the dedicated venv that
Claude Code spawns:
./scripts/setup_mcp.sh
Registration lives in the checked-in .mcp.json (project scope).
