@sero-ai/plugin-weight-tracker

Weight tracker app for Sero — track your progress, visualise trends, and stay motivated with gentle encouragement.

Sero Plugin Install

Install in Sero → Admin → Plugins with:

git:https://github.com/monobyte/sero-weight-tracker.git

Sero clones the source repo, installs its dependencies locally, builds the UI, and then hot-loads the plugin into the sidebar.

Pi CLI Usage

Install as a Pi package:

pi install git:https://github.com/monobyte/sero-weight-tracker.git

The agent gains a weight tool (log, list, remove, goal, status, clear) and a /weight command. State is stored in .sero/apps/weight-tracker/state.json relative to the workspace root (or ~/.sero-ui/apps/weight-tracker/state.json when running inside Sero, since this is a global-scoped app).

Sero Usage

When loaded in Sero, the web UI mounts in the main app area and watches the same state file. Changes from the agent or the UI are reflected instantly in both directions.

Features:

• Log entries — record weight with optional date and notes
• Trend chart — SVG line chart with gradient fill
• Stats — current weight, weekly change, total change, goal progress
• Goal tracking — set a target and see your progress bar fill up
• Encouragement — motivational messages based on your recent trends

State File

This is a global-scoped app — in Sero, state lives at:

~/.sero-ui/apps/weight-tracker/state.json

In Pi CLI (no Sero), it falls back to workspace-relative:

workspace-root/.sero/apps/weight-tracker/state.json

{
  "entries": [
    {
      "id": 1,
      "weight": 80.5,
      "date": "2025-01-01",
      "note": "Starting fresh!",
      "createdAt": "2025-01-01T09:00:00.000Z"
    }
  ],
  "nextId": 2,
  "unit": "kg",
  "goal": null
}
