What it does

Quadas C Assessment For Diagnostic Accuracy Studies is an agent skill from aipoch/medical-research-skills. Automated bias assessment for diagnostic accuracy studies using QUADAS-C criteria. Requires full text input.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `quadas-c-assessment-for-diagnostic-accuracy-studies_audit_result_v1.json`, `references/prompts.md` and `scripts/extract_pdf.py`).

It sits in Data & Analytics, covering Data analysis. The repository describes itself as: Hundreds of agent skills for medical research, including protocol design, data analysis, evidence insights, and academic writing. The licence is MIT.

When your agent uses it

  • Tasks that involve Data analysis

Example prompts

  • “/quadas-c-assessment-for-diagnostic-accuracy-studies”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Confirm the user input, output path, and any required config values.
  2. Edit the in-file CONFIG block or documented parameters if the script uses fixed settings.
  3. Run python scripts/extract_pdf.py with the validated inputs.
  4. Review the generated output and return the final artifact with any assumptions called out.

What it can do on your machine

Read from SKILL.md and the folder at commit 686e09d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Quadas C Assessment For Diagnostic Accuracy Studies loads about 1.1k tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 40 tokens; SKILL.md has 517 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~40
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

QUADAS-C Assessment Skill

This skill automates the risk of bias assessment for diagnostic accuracy studies comparing two or more index tests (QUADAS-C).

When to Use

  • Use this skill when you need automated bias assessment for diagnostic accuracy studies using quadas-c criteria. requires full text input in a reproducible workflow.
  • Use this skill when a data analytics task needs a packaged method instead of ad-hoc freeform output.
  • Use this skill when the user expects a concrete deliverable, validation step, or file-based result.
  • Use this skill when scripts/extract_pdf.py is the most direct path to complete the request.
  • Use this skill when you need the quadas-c-assessment for diagnostic accuracy studies package behavior rather than a generic answer.

Key Features

  • Scope-focused workflow aligned to: Automated bias assessment for diagnostic accuracy studies using QUADAS-C criteria. Requires full text input.
  • Packaged executable path(s): scripts/extract_pdf.py plus 1 additional script(s).
  • Reference material available in references/ for task-specific guidance.
  • Structured execution path designed to keep outputs consistent and reviewable.

Dependencies

  • Python: 3.10+. Repository baseline for current packaged skills.
  • Third-party packages: not explicitly version-pinned in this skill package. Add pinned versions if this skill needs stricter environment control.

Example Usage

See ## Usage above for related details.

bash
cd "20260316/scientific-skills/Data Analytics/quadas-c-assessment-for-diagnostic-accuracy-studies"
python -m py_compile scripts/extract_pdf.py
python scripts/extract_pdf.py --help

Example run plan:

  1. Confirm the user input, output path, and any required config values.
  2. Edit the in-file CONFIG block or documented parameters if the script uses fixed settings.
  3. Run python scripts/extract_pdf.py with the validated inputs.
  4. Review the generated output and return the final artifact with any assumptions called out.

Implementation Details

  • Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
  • Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
  • Primary implementation surface: scripts/extract_pdf.py with additional helper scripts under scripts/.
  • Reference guidance: references/ contains supporting rules, prompts, or checklists.
  • Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
  • Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

When to Use This Skill

Use this skill when:

  1. You have the full text of a clinical research paper.
  2. You need to assess the risk of bias using the QUADAS-C tool.
  3. The study compares at least two diagnostic methods.

Usage

The skill processes the paper through the following steps:

  1. Extraction: Identifies diagnostic methods compared in the study.
  2. Assessment: For each method, runs a QUADAS-2 assessment.
  3. Signaling Questions: Answers specific QUADAS-C signaling questions for 4 domains:
    • Patient Selection
    • Index Test
    • Reference Standard
    • Flow and Timing
  4. Risk of Bias: Determines "Low", "High", or "Unclear" risk for each domain.
  5. Reporting: Generates a structured JSON report.

Execution

To run the assessment, use the provided Python script. You can pass the paper text as a command-line argument or via a file.

bash

# Example: Process a text file containing the paper
python scripts/quadas_c.py --file "path/to/paper.txt"

Output Format

The output is a JSON object with the following structure:

json
{
  "P": "Low/High/Unclear",
  "I": "Low/High/Unclear",
  "R": "Low/High/Unclear",
  "FT": "Low/High/Unclear"
}

Reference

See references/prompts.md for the specific signaling questions and risk of bias criteria used in the LLM prompts.

Helper Scripts

PDF Text Extraction

When the user provides a PDF file path, use extract_pdf.py to extract the text content before assessment:
