eCTD XML Compiler

ID: 197

Automatically convert uploaded drug application documents (Word/PDF) into XML skeleton structure compliant with eCTD 4.0/3.2.2 specifications.

When to Use

• Use this skill when the task needs Automatically convert uploaded drug application documents (Word/PDF) into XML skeleton structure compliant with eCTD 4.0/3.2.2 specifications.
• Use this skill for academic writing tasks that require explicit assumptions, bounded scope, and a reproducible output format.
• Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

Key Features

• Scope-focused workflow aligned to: Automatically convert uploaded drug application documents (Word/PDF) into XML skeleton structure compliant with eCTD 4.0/3.2.2 specifications.
• Packaged executable path(s): scripts/main.py.
• Reference material available in references/ for task-specific guidance.
• Structured execution path designed to keep outputs consistent and reviewable.

Dependencies

python-docx>=0.8.11    # Word document parsing
PyPDF2>=3.0.0          # PDF text extraction
lxml>=4.9.0            # XML processing

Example Usage

See ## Usage above for related details.

cd "20260318/scientific-skills/Academic Writing/ectd-xml-compiler"
python -m py_compile scripts/main.py
python scripts/main.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/main.py with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

Implementation Details

See ## Workflow above for related 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/main.py.
• 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.

Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

python -m py_compile scripts/main.py

Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

python -m py_compile scripts/main.py
python scripts/main.py --help

Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

Overview

eCTD (electronic Common Technical Document) is the electronic Common Technical Document standard established by ICH for submitting drug registration applications to regulatory agencies such as FDA and EMA.

This tool parses uploaded drug application documents (Word/PDF) and converts them into XML skeleton structure compliant with eCTD 4.0/3.2.2 specifications.

Arguments

Options

Examples

# Basic usage - auto-detect module
python skills/ectd-xml-compiler/scripts/main.py document1.docx document2.pdf

# Specify output directory and module
python skills/ectd-xml-compiler/scripts/main.py -o ./my-ectd -m m3 quality-doc.docx

# Validate generated XML

Input Document Processing

Supported Formats

• Microsoft Word (.docx, .doc)
• PDF (.pdf)

Document Parsing Logic

1. Title Recognition: Extract heading hierarchy based on font size and style
2. TOC Mapping: Auto-recognize section numbers (e.g., 3.2.S.1.1)
3. Metadata Extraction: Extract author, date, version, and other information
4. Content Classification: Map to corresponding eCTD modules based on keyword matching

Module Auto-Recognition Rules

Output Structure

Generated eCTD skeleton contains:

index.xml

Master index file containing references and sequence information for all modules.

Module XML (m1.xml - m5.xml)

XML skeleton for each module, containing:

• Document hierarchy structure (<leaf>, <node>)
• Cross-references (<cross-reference>)
• Attribute definitions (ID, version, operation type)

MD5 Checksums

MD5 checksum values for each file to ensure integrity.

Installation

# Install dependencies
pip install python-docx PyPDF2 lxml

Validation

Using --validate option can validate generated XML:

• DTD structure validation
• Required elements and attributes check
• Cross-reference integrity check

Risk Assessment

Security Checklist

• [ ] No hardcoded credentials or API keys
• [ ] No unauthorized file system access (../)
• [ ] Output does not expose sensitive information
• [ ] Prompt injection protections in place
• [ ] Input file paths validated (no ../ traversal)
• [ ] Output directory restricted to workspace
• [ ] Script execution in sandboxed environment
• [ ] Error messages sanitized (no stack traces exposed)
• [ ] Dependencies audited

Prerequisites

No additional Python packages required.

Evaluation Criteria

Success Metrics

• [ ] Successfully executes main functionality
• [ ] Output meets quality standards
• [ ] Handles edge cases gracefully
• [ ] Performance is acceptable

Test Cases

1. Basic Functionality: Standard input → Expected output
2. Edge Case: Invalid input → Graceful error handling
3. Performance: Large dataset → Acceptable processing time

Lifecycle Status

• Current Stage: Draft
• Next Review Date: 2026-03-06
• Known Issues: None
• Planned Improvements:

- Performance optimization - Additional feature support

Output Requirements

Every final response should make these items explicit when they are relevant:

• Objective or requested deliverable
• Inputs used and assumptions introduced
• Workflow or decision path
• Core result, recommendation, or artifact
• Constraints, risks, caveats, or validation needs
• Unresolved items and next-step checks

Error Handling

• If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
• If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
• If scripts/main.py fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
• Do not fabricate files, citations, data, search results, or execution outcomes.

Input Validation

This skill accepts requests that match the documented purpose of ectd-xml-compiler and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

ectd-xml-compiler only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.
