Muscle Gain

Track muscle building with weight progression, protein tracking, and strength milestones

Security Scan

The skill's description (local encrypted offline storage and automatic tracking) is plausible, but it's an instruction-only skill with no code, no install, and no declared storage/config paths — the promises about how data is stored and processed aren't supported by any concrete mechanism.

Purpose & Capability

The name/description (muscle tracking, protein, lifts, photos) matches the requested footprint: there are no credentials, binaries, or installs required. However, features that imply persistent, automated data processing (auto-calculated protein, milestone surfacing, charts, encrypted local storage) require state and code; the skill package provides no implementation or config paths to do that.

Instruction Scope

SKILL.md gives usage semantics and privacy claims ("All data stays local on your machine — encrypted and stored offline") but contains no runtime instructions or commands for how to collect/store/process data. It neither specifies file paths, formats, or encryption mechanisms nor indicates how progress photos are kept locally. That ambiguity means the agent or downstream tooling would need to decide how to persist or transmit data, which could lead to unintended cloud uploads or unclear handling of images.

Install Mechanism

No install spec and no code files are present, which minimizes risk from downloads or executes. Because nothing is installed, there's no install-time supply-chain risk in the package itself.

Credentials

The skill requests no environment variables, credentials, or config paths — good for proportionality. However, its strong privacy claim (encrypted local storage, no cloud) is unverifiable given the lack of implementation details; users should not assume the platform or agent will enforce this.

Persistence & Privilege

always is false and the skill does not request persistent agent-level privileges or modify other skills. It relies on the agent to run when invoked, which is appropriate for this type of skill.

What to consider before installing

This skill is an instruction-only description of a muscle-tracking assistant; it contains no code or install steps. Before installing or trusting it with photos and personal data, ask the publisher or maintainer how data will actually be stored and encrypted (file paths, formats, encryption algorithm, key management, and backups). If you rely on the promise "all data stays local," require concrete details or prefer a skill that provides code or a local client you can inspect. Be cautious about uploading progress photos or sensitive health data until you confirm where the agent will store them and whether any external services are contacted. If you decide to proceed, test with dummy data first and monitor agent activity or logs for any unexpected network calls.

Build lean muscle with precision tracking of strength, nutrition, and body composition.

What it does

The muscle-gain skill transforms your fitness journey into a data-driven process. Log body weight and measurements to track lean mass gains, monitor daily protein intake against personalized targets, and record strength progression across your key lifts. Automatically surfaces milestone achievements and flags underperformance to keep you accountable. Built for serious lifters, casual athletes, and anyone committed to measurable gains.

Usage

Log measurements Track body weight, chest, arms, shoulders, waist, and thighs weekly. Provides trend analysis to distinguish lean mass from water weight.

Track protein Log meals and auto-calculate daily protein intake. Compares against your personalized target (0.7–1g per pound of body weight).

Check gains View strength progression charts for squats, deadlifts, bench press, and other key lifts. See month-over-month and year-over-year trends.

Set targets Define your bulk targets (body weight gain, protein intake, lift PRs) and get reminded when targets are within reach or falling behind.

Progress pics Organize before/after photos and annotate with measurements and lift PRs from the same date for visual proof of progress.

Key Metrics

• Body weight - Daily logged weight
• Measurements - Arms, chest, shoulders, waist, thighs, neck (weekly)
• Strength lifts - Squat, deadlift, bench press, overhead press, barbell rows (log reps × weight)
• Protein intake - Daily grams tracked against target
• Caloric surplus - Optional integration with nutrition logging to track daily surplus
• Progress photos - Timestamped images with metadata (date, weight, lift PRs)

Tips

1. Weigh yourself daily, same time - Morning after bathroom, before food. Track the trend, not daily variance.

2. Protein first, everything else follows - Hit your protein target (0.8–1g per pound) before worrying about total calories. Lean mass gain demands protein surplus.

3. Log lifts immediately after sets - Record reps, weight, and RPE (rate of perceived exertion). Patterns in RPE reveal when you're underrecovering.

4. Measure weekly on the same day - Sunday morning works. Take measurements in identical conditions to avoid false positives from water retention or pump.

5. All data stays local on your machine - Your training logs, weight history, and progress photos are encrypted and stored offline. No cloud upload, no third-party access, full privacy.
