longitudinal SKILL.md skillA
longitudinal from mycelium-hq/ai-brain-starter is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mycelium-hq/ai-brain-starter/longitudinal@git:20260707.f0ac903Pins git:20260707.f0ac903 in mdr.lock. Pin the fingerprint instead.

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).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
When the user types /longitudinal, run the multi-year correlation pass and surface only the strongest signals across years of health-mcp + journal data. ## Language Generate the report in the language the user writes in. If Spanish, all sections including the panel commentary are in Spanish. ## Scope resolution Parse the argument for window: - `all` -> earliest record in DB to today - `Ny` -> last N years (e.g. 5y, 3y) - `Nm` -> last N months (e.g. 18m) - blank -> 365 days If `all`, query the DB for the earliest record date first: ```python SELECT MIN(start_date) FROM records WHERE value IS NOT NULL ``` ## Step 1: top_signals first (the noise filter) Always call `health_top_signals(vault_root=..., lookback_days=N, min_strength="moderate")` first. This is Lara Briden's dissent codified: most correlations are noise. The substrate has already filtered. Start with what's left. If `signal_count == 0`, report "no signals above noise threshold for this window" and stop — do not invent. Surface what IS there: the deltas and r-values that didn't quite clear the threshold, in case the user wants to relax it. ## Step 2: Floor x body fingerprints for the user's top 3 Floors …

How to install
mdr add mycelium-hq/ai-brain-starter/longitudinal@sha256:9a94c1e81713f3f6The line at the top of this page pins the label git:20260707.f0ac903, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
