Use when looking for research topics a longitudinal cohort database can answer (NHIS, UK Biobank, an institutional EMR or registry). Profiles the cohort, matches PI expertise, scans literature saturation and returns ranked topic proposals with gap evidence.
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
# Find-Cohort-Gap Skill
Output directory: user-specified (default: current working directory).
## Phase 0: Cohort Intake
The cohort does not have to be one this skill has heard of. Route on what the user
actually has.
| The user has… | Do this |
|---------------|---------|
| A **named public cohort** (NHIS, UK Biobank, KNHANES, …) | Fill the profile from published documentation. Cite the source for every field. |
| A **codebook / data dictionary / CSV export** of their own registry or EMR extract | Run the input adapter below. This is the common case — an institutional registry or single-centre export that no public documentation describes. |
| A **review, guideline, or preprint** defining the clinical domain | Attach it as domain context (`--context`), as a file or a URL. |
### Input adapter (local codebook / documents)
```bash
python3 "${CLAUDE_SKILL_DIR}/scripts/build_cohort_profile.py" \
--codebook data_dictionary.csv \
--context narrative_review.pdf --context https://example.org/guideline \
--cohort-name "Institutional CT registry" --out-dir .
```
Formats: `.csv` / `.tsv` / `.json` / `.md` / `.txt` (stdlib), `.xlsx` (needs `openpyxl`),

How to install
mdr add aperivue/medsci-skills/find-cohort-gap@sha256:9d8fc26827ac134fThe line at the top of this page pins the label git:20261003.efd513d, 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.
