longitudinal skillA

longitudinal is agent-read markdown (skill) from mycelium-hq/ai-brain-starter: Use when the user wants multi-year health patterns from HealthKit + journal data: "patterns in my health data," "what does my body tell me," "correlations between mood and HRV," "Floor x body fingerprint," long-term trends in sleep, HRV, VO2max, cycle, or symptoms, "how has my body changed over the years," or /longitudinal. NOT for single-day analysis (use /health-doctor), this-week patterns (use /weekly), or journal-only pattern extraction (use /patterns)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add mycelium-hq/ai-brain-starter/longitudinal@git:20260707.f0ac903
Exact content
mdr add mycelium-hq/ai-brain-starter/longitudinal@sha256:9a94c1e81713f3f6

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
