main.dart now builds MaterialApp's theme from buildAppTheme() instead of ColorScheme.fromSeed(Colors.teal) -- theme.dart existed but was never actually used until this commit. photo_viewer_screen.dart, settings_screen.dart, and day_status_calendar.dart's raw Colors.* literals (Colors.black, Colors.red, Colors.white38, Colors.grey.shade800, ...) now read from Theme.of(context) instead. Also rewrites CLAUDE.md's Visual Design & Theming section, which previously contradicted the unified-design-system skill (noise texture, multi-layered shadows, ColorScheme.fromSeed -- all things that skill explicitly forbids). This was the other prerequisite the on-fill/warm-palette fixes actually needed: theme.dart existing but unwired meant the app was still running Flutter's default seeded theme. |

diet_guard
A log-to-unlock gate: locks the desktop until a meal is logged once a meal slot (08:00 / 12:00 / 16:00 / 20:00) has elapsed without one, and tracks a sealed daily calorie/macro budget.
Install
bash install.sh
This installs the package + dependencies into system Python's user
site-packages (the systemd service runs /usr/bin/python directly, not a
venv — see CLAUDE.md), installs the systemd user timer, seals your daily
budget, and locks the budget file immutable.
Usage
python -m diet_guard init # one-time: compute and seal today's budget
python -m diet_guard gate --demo # test the lock window (safe, closeable)
The timer runs the gate automatically every ~30 minutes; no manual invocation is needed once installed.
MCP server
An optional Model Context Protocol server
lets an MCP client (Claude Code and its subagents) query today's intake and log
meals as typed tools instead of shelling out to the CLI. It runs in its own
venv (~/.venvs/diet-guard-mcp) so the mcp SDK never touches the
dependency-light system/CLI python path.
Tools:
get_status— today's consumed kcal + macros, the consumption band (on track/approaching limit/OVER BUDGET, or none when no budget is sealed), plus due / logged / current meal slots.list_today— today's logged meals (description, kcal, macros, source, slot).get_slots— the day's fixed meal slots and the current one.log_meal(description, grams=, kcal=, protein=, carbs=, fat=, slot=, confirm=False)— gated write: withconfirm=Falseit previews the resolved nutrition and target slot and mutates nothing; onlyconfirm=Trueappends the entry. The gate is intrinsic — never add this tool to a permission allowlist, since a client's auto-approve mode would otherwise bypass the human confirmation.
The read tools deliberately never expose the raw daily budget number (only the
qualitative band), nor the sealed .budget file, the shared HMAC key, or the
sync token — the budget stays hidden by design.
Setup:
bash scripts/setup_mcp.sh # create the venv and install diet_guard[mcp]
Then restart Claude Code in this repo and approve the project MCP server
(registered in .mcp.json).
Development
python -m venv .venv && .venv/bin/pip install -r requirements.txt
.venv/bin/pre-commit install && .venv/bin/pre-commit install --hook-type pre-push
.venv/bin/python -m pytest diet_guard/tests/ --cov=diet_guard --cov-branch --cov-fail-under=100
