alterlab-redcap-cdisc

alterlab-redcap-cdisc is a skill for Claude Code from AlterLab-IEU/AlterLab-Academic-Skills. It costs 230 tokens per session (2,866 once invoked), scanned A, original, MIT.

A design tool for REDCap, a system used to collect research-study data, and CDISC, a set of standards for submitting clinical data. It turns study requirements into REDCap data dictionaries and maps variables to CDASH and SDTM standards.

In plain words
What is it for?
Use it to design screening and follow-up forms, create an importable 18-column REDCap CSV, check a data dictionary, and map research variables to CDISC domains and coded terms.
Why use it?
It reduces errors when designing electronic forms, validation rules, branching questions, and study data mappings. It also makes clear that it creates files and mappings rather than importing them into a live REDCap server.

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

alterlab-redcap-cdisc 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/lint_data_dictionary.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

REDCap & CDISC — Research Data Capture and Standards Alignment

Designs validated electronic data capture (EDC) instruments in REDCap and aligns a study's variables to CDISC submission standards. It owns two jobs that overlap with sibling skills only at the edges:

  1. REDCap project & instrument design — turn a study's requirements into a REDCap data dictionary (the importable 18-column CSV), with correct field types, validation, branching logic, longitudinal events, and survey settings.
  2. CDISC alignment — map collected variables to CDASH (collection) and SDTM (tabulation) domains, and tie coded values to CDISC Controlled Terminology (NCI-EVS), so the data is submission- and reuse-ready.

This is design + standards work, not a live-API connector. Producing the CSV and the mapping is in scope; importing it into a running REDCap server is the instance owner's job (REDCap's own API/UI).

Quick Start

Build me a REDCap data dictionary for a 3-arm RCT screening + follow-up.
Add branching logic so the pregnancy question only shows when sex = female.
Lint this data_dictionary.csv before I import it.
Map my CRF variables to CDISC SDTM domains and CDASH fields.
Which SDTM domain and controlled-terminology codelist does "adverse event" go in?

→ Draft or read the dictionary, run scripts/lint_data_dictionary.py to catch structural errors, then (for CDISC) produce a variable → CDASH → SDTM mapping table. Always state which facts are design conventions vs. instance-specific.


When to Use This Skill

Use it when the request is about building the instrument or making it standards-compliant:

  • "Build / design a REDCap project, form, or data dictionary."
  • "Write the importable REDCap CSV for these variables."
  • "Set up branching logic / show-field logic / field validation / required fields."
  • "Configure longitudinal events / arms / repeating instruments / a survey."
  • "Lint / validate / debug my data dictionary before import."
  • "Map my study to CDISC — which SDTM domain / CDASH field / codelist?"
  • "Make my CRF submission-ready (SDTM/CDASH/CDISC CT)."

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.
