Make Firebase the visible sync path, and GitHub the mirror it now is
Four things about the sync settings read wrong on the phone, all of them
left over from when GitHub was the only backend:

- "Connect GitHub" sat on the primary path as a peer of "Connect Firebase",
  implying a choice. It is not one: GitHub is the cutover mirror. Its whole
  configuration -- device-flow OAuth, owner, repo, client id, PAT fallback --
  now lives under "Advanced (GitHub mirror)".
- "Test connection" builds a GitHubClient and calls canAccessRepo(). It has
  never said anything about Firebase, so it is now "Test GitHub connection",
  and its result messages name GitHub too.
- Once connected, the account still rendered as an editable email box beside
  an empty password box, which reads as "you still have to enter this" -- a
  connected device looked unconfigured. It now shows the account as text with
  a Disconnect button, and the form appears only when disconnected.

Also pins crdt-sync v0.5.1 (from v0.3.0), the shared-config release the
Firebase cutover needs; verified importable under /usr/bin/python3, which is
what diet-guard-gate.service actually runs.

Adds coverage for both Firebase states, which had none: the disconnected form
and the connected read-only display.

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: with confirm=False it previews the resolved nutrition and target slot and mutates nothing; only confirm=True appends 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
