In plain words
What is it for?
Use it to import health files, set up the graph, check stale links, and analyse supplements, symptoms, sleep, wearable data, and patterns.
Why use it?
It explains the repository’s working rules and available analyses before an agent changes files or processes health data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

personal-health-graph CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this repo is

Personal Health Graph (PHG) is a structured markdown file system — not a software project. There is no build step, no test suite, no dependencies. The "code" is methodology: structured natural language skill files that instruct LLMs how to analyze health data.

How to work with this repo

Running skills

Skills are in skills/*.md and skills/workflows/*.md. To run a skill, read the skill file and follow its instructions against the relevant data files it specifies in its reads: frontmatter field.

Entry point skills:

  • skills/INTAKE.md — process files dropped in inbox/ into structured PHG files
  • skills/QUICKSTART.md — guided onboarding wizard; run if the graph is newly set up
  • skills/MAINTENANCE.md — scheduled audit of staleness and cross-reference validity

Analysis skills (require populated data first):

  • skills/SUPPLEMENT_REVIEW.md — evaluate supplement stack against labs and genetics
  • skills/SYMPTOM_ANALYSIS.md — correlate symptoms with sleep, wearables, supplements
  • skills/PATTERN_DETECTION.md — full-history scan for correlations and anomalies
  • skills/DOCTOR_PREP.md — compile structured visit summary for a provider
  • skills/MASTER_ANALYSIS.md — comprehensive 5-phase analysis
  • skills/HEALTH_MEMO.md — Amazon-style narrative health briefing
  • skills/BASELINE_REPORT.md — first-run assessment with gap analysis
  • skills/RISK_ASSESSMENT.md — cardiovascular and genetic risk review
  • skills/EXPERIMENT.md — design and evaluate N-of-1 self-experiments (writes EXPERIMENTS.md)
  • skills/FACT_AUDIT.md — re-verify a prior report's claims against primary sources
  • skills/SPECIALIST_TRANSLATOR.md — specialty-native handoff briefs
  • skills/TIMELINE.md — rebuild TIMELINE.md, the derived chronological event spine
  • skills/DASHBOARD.md — render the graph into a self-contained HTML dashboard (injects data into templates/dashboard_shell.html; never edit the shell's markup or add external resources)

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
