Description
Track intermittent fasting windows, extended fasts, and autophagy milestones
README (SKILL.md)
Fasting Tracker
Monitor intermittent and extended fasting with precision—track eating windows, metabolic phases, and autophagy milestones in real-time.
What it does
- Fast Timer: Start a fast and get real-time elapsed tracking with countdown to key metabolic milestones
- Eating Window Tracking: Log when you break your fast and automatically calculate your eating window duration
- Metabolic Milestones: Receive alerts at ketosis (12h), fat adaptation (16h), autophagy (24h), and deeper cellular renewal thresholds
- Smart History: Review past fasts with duration, eating windows, and consistency metrics
Usage
Start Fast
"Start a fast" or "begin fasting"
- Logs the fast start time
- Displays current time and target milestones
- Sets background tracking (runs even when you close the app)
Break Fast
"Break my fast" or "I'm eating now"
- Records the end time
- Calculates total fast duration
- Shows eating window recommendation and next fast opportunity
Check Timer
"How long have I been fasting?" or "fasting status"
- Displays elapsed time
- Shows next metabolic milestone and time remaining
- Displays current autophagy phase if applicable
Fast History
"My fasting stats" or "fasting progress"
- Lists recent fasts with duration
- Shows weekly consistency
- Displays longest streak and average fast length
Set Schedule
"Schedule my fasts" or "fasting protocol"
- Configure preferred fasting protocol (16:8, OMAD, etc.)
- Set daily reminders for fast start/end times
- Customize notifications for key milestones
Metabolic Timeline
| Duration | Milestone | Status |
|---|---|---|
| 12 hours | Ketosis Begins | Glycogen depletes; body shifts to fat burning |
| 16 hours | Fat Adaptation | Insulin drops further; metabolic efficiency improves |
| 24 hours | Autophagy Activation | Cellular cleanup intensifies; damaged proteins recycled |
| 36 hours | Deep Autophagy | Mitochondrial renewal accelerates; immune reset begins |
| 48 hours | Cellular Regeneration | Growth hormone peaks; stem cell activation (rodent studies) |
| 72+ hours | Extended Benefits | Sustained autophagy; metabolic recalibration; requires medical oversight |
Fasting Protocols
- 16:8 Intermittent: 16-hour fast, 8-hour eating window (most beginner-friendly)
- 18:6 Intermediate: 18-hour fast, 6-hour eating window (moderate difficulty)
- 20:4 Warrior: 20-hour fast, 4-hour eating window (lean gains focus)
- OMAD (One Meal A Day): 23-hour fast, 1-hour eating window (advanced)
- 24-Hour Fast: Full day fast (once or twice weekly)
- Extended Fast: 36–72+ hours (consult healthcare provider; requires electrolyte management)
Tips
- Electrolytes Matter: Extended fasts deplete sodium, potassium, and magnesium. Supplement or drink bone broth to prevent cramping and fatigue.
- Hydration is Essential: Water, herbal tea, black coffee, and green tea are fasting-friendly; any calorie breaks the fast.
- Listen to Your Body: Fatigue, dizziness, or intense hunger warrants eating—fasting should enhance, not impair, daily function.
- Consistency Beats Intensity: A sustainable 16:8 protocol done for months outpaces sporadic 72-hour fasts; build the habit first.
- All data stays local on your machine: Your fasting logs, schedules, and metrics never leave your device—complete privacy, no cloud sync required.
Usage Guidance
This skill appears internally inconsistent: it promises background timers, notifications, and local storage but provides no code, install steps, or declared permissions to implement them. Before installing or enabling it: (1) ask the author how background tracking and notifications are implemented and where logs are stored; (2) require explicit instructions about any system changes (cron jobs, services, notification APIs) and the exact file paths used; (3) prefer a version that includes an install spec or code you can review, or run the skill in a restricted/sandboxed environment; (4) do not grant system-level scheduling or file-access permissions to the agent unless you understand and approve the exact actions it will take.
Capability Analysis
Type: OpenClaw Skill
Name: fasting-tracker
Version: 1.0.0
The OpenClaw AgentSkills skill bundle for 'fasting-tracker' appears benign. The `SKILL.md` content is entirely focused on its stated purpose of tracking fasting, providing information, and usage instructions. There are no indications of prompt injection attempts against the AI agent, no instructions for malicious execution, data exfiltration, persistence, or obfuscation. Notably, the documentation explicitly states, 'All data stays local on your machine', which is a strong indicator against data exfiltration.
Capability Assessment
Purpose & Capability
The name/description promise real-time background tracking, scheduled reminders, notifications, and local storage of fasting logs. However, the package is instruction-only with no code, no install steps, no declared access to notifications, and no file/storage paths. The capability set described is not supported by the artifacts provided.
Instruction Scope
SKILL.md uses vague, operational language ('Sets background tracking', 'runs even when you close the app', 'daily reminders', 'alerts') but gives no concrete instructions on how to schedule background tasks, where to persist logs, or how to send notifications. That vagueness grants the agent broad discretion and could lead it to attempt system-level actions (cron jobs, notification APIs, writing to arbitrary paths) without clear constraints.
Install Mechanism
No install spec and no code files are present, so nothing will be written to disk or downloaded during install. This is lower-risk from an installation perspective, but also means promised persistent features cannot be implemented as-is.
Credentials
The skill declares no environment variables or credentials (proportionate). However, it claims 'All data stays local' without specifying storage locations or access requirements — that claim cannot be validated from the provided materials.
Persistence & Privilege
Although the registry flags do not request 'always' or elevated privileges, the instructions imply persistent background operation and notifications. Without explicit implementation details, the agent would need to create persistent system artifacts (scheduled tasks, background services, or files) to fulfill that promise — a mismatch that merits caution.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install fasting-tracker - After installation, invoke the skill by name or use
/fasting-tracker - Provide required inputs per the skill's parameter spec and get structured output
