What it does

Evidence-based health research using tiered trusted sources with GRADE-inspired evidence ratings. Integrates Apple Health data for personalized context. Use when user asks health, nutrition, exercise, sleep, or wellness questions.

Installed, it changes the agent in these ways.

What this skill changes about the agent is not written down here yet. The listing was collected from its source, and the description is in its own SKILL.md.

Expertise

Domain judgement the base model does not have.

The skill itself

This is the whole product. A skill is instructions the model reads, so there is nothing behind the listing you cannot see first — the front matter loads with every session, and the body below it loads when the skill triggers.

26## Depth Levels
27
28| Level | Flag | Tools | Time | Use When |
29|-------|------|-------|------|----------|
30| Quick | *(default)* | WebSearch | ~30s | Simple factual questions |
31| Deep | --deep | WebSearch + Tavily | ~90s | Competing claims, nuanced topics |
32| Full | --full | WebSearch + Tavily + Firecrawl | ~3min | Controversial topics, need primary sources |
33
34## How It Works
35
36### 1. Parse Query & Detect Topic Category
37
38Classify the question into one of:
39- **Nutrition/Supplements** (examine.com gets priority)
40- **Exercise/Training** (PubMed + ACSM get priority)
41- **Sleep** (focus sleep-specific databases)
42- **Disease/Condition** (condition-specific orgs + clinical guidelines)
43- **Medication/Treatment** (FDA, EMA, Cochrane get priority)
44- **Mental Health** (APA, mental health orgs)
45- **General Wellness** (broad search across all tiers)
46
47### 2. Search Evidence Sources (Tiered)
48
49Search sources in priority order. See references/sources.md for complete domain list.
50
51**Tier 1 -- Primary Research** (highest weight):
52- PubMed/PMC, Cochrane Library, WHO, ClinicalTrials.gov
53
54**Tier 2 -- Clinical/Institutional** (high weight):
55- Mayo Clinic, Hopkins Medicine, Cleveland Clinic, Harvard Health
56- Condition-specific: AHA, ACS, ADA, Alzheimer's Association
57
58**Tier 3 -- Expert Analysis** (medium weight):
59- Examine.com, STAT News, Health News Review
60- Consensus.app, Epistemonikos
61
62**Tier 4 -- Quality Journalism** (context/framing):
63- The Atlantic, NYT, NPR, Guardian, FiveThirtyEight
64
65#### Search Strategy by Depth
66
67**Quick** (default):
68```
69WebSearch(query, allowed_domains=[Tier 1 + Tier 2 domains])
70WebSearch(query + "systematic review OR meta-analysis", allowed_domains=[Tier 1])
71```
72
73**Deep** (--deep):
74All Quick searches PLUS:
75```
76tavily-search(query, include_domains=[Tier 1-3])
77WebSearch(query + "expert opinion OR position statement", allowed_domains=[Tier 2-3])
78WebSearch(query + "risks OR side effects OR contraindications")
79```
80
81**Full** (--full):
82All Deep searches PLUS:
83```
84firecrawl-research for top 2-3 most relevant results from Tier 1
85WebSearch for competing/contrarian viewpoints
86WebSearch(query + "retracted OR debunked OR misleading")
87```
88
89### 3. Pull Personal Health Context (unless --no-personal)
90
91Query Apple Health database for relevant metrics:
92
93```bash
94python ~/ai_projects/claude-skills/health-data/scripts/health_query.py --format json vitals
95python ~/ai_projects/claude-skills/health-data/scripts/health_query.py --format json daily
96python ~/ai_projects/claude-skills/health-data/scripts/health_query.py --format json sleep --days 7
97python ~/ai_projects/claude-skills/health-data/scripts/health_query.py --format json workouts --days 30
98```
99
100Select ONLY metrics relevant to the query:
101- Exercise question -> recent workouts, activity, resting HR, VO2 max
102- Sleep question -> sleep data, HRV
103- Nutrition question -> weight trends, activity level
104- Heart question -> HR, HRV, resting HR, blood pressure
105
106### 4. Synthesize with Evidence Grading
107
108Rate each claim using simplified GRADE scale:
109
110| Rating | Meaning | Based On |
111|--------|---------|----------|
112| **Strong** | Consistent evidence from systematic reviews/meta-analyses or multiple large RCTs | Level I-II evidence |
113| **Moderate** | Supported by well-designed studies but some inconsistency or limitations | Level II-III evidence |
114| **Weak** | Limited evidence, small studies, or conflicting results | Level III-IV evidence |
115| **Minimal** | Expert opinion, case reports, or preliminary/animal studies only | Level V evidence |
116| **Contested** | Active scientific debate with credible evidence on both sides | Mixed levels |
117
118### 5. Format Output

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈70
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
5,205

The instruction body and 3 supporting files, read only when the skill fires.
2.6%
of a 200k window
Ten skills this size would take about 26% of the window before you open a file.
050k100k150k200k context window

5.3k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been published here. It is in the skill’s own SKILL.md, which its author has not sent to the marketplace yet.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

It writes no files and reaches no network. All it changes is how the model reasons and writes.

What it asks for
Writes filesno
Network accessno

Read from the allowed-tools line of this skill’s own SKILL.md. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

4 files, 21.1 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md6.6 kB
  • instructions.md7.3 kB
  • .claude-plugin/plugin.json0.3 kB
  • references/sources.md6.9 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 4 files you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

Keeps workingfor good — the files are yours once they are on disk
Updatesevery update its author ships, delivered through this account

You can read the whole bundle before paying — the SKILL.md above is the product, not a preview of it. What the money buys is the delivery: the folder packaged and handed to your machine by key, every update its author ships, and our support if it does not do what this listing says. The terms of use are MIT, set by the author and unchanged by buying it here.

Payment runs through Stripe, on a page like this one rather than a redirect. Once there is an account it joins the same mcprush invoice as everything else you run, so there is never a second card to enter.

Which clients pick it up on their own

A skill is a folder of text. A client with a skills folder reads it without being told; everywhere else the same text works, it is just handed to the model rather than found.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.

Reviews

no reviews yet · no installs yet

Nobody has reviewed this skill yet. The rating is the mean of the reviews written here, so there is none until somebody writes the first.

Who can post

Only accounts that have had the skill installed for fourteen days, so a review is written after living with it rather than after reading it. Publishers may reply once.
