--- title: "Reference Document Architecture" description: "Complete reference document structure for the python3-development skill" version: "1.0.0" last_updated: "2025-11-02" document_type: "architecture" status: "historical-proposal" implementation_status: "not-implemented" archived_date: "2025-11-02" note: "This document represents an architectural proposal that was never implemented. The actual python3-development skill uses a different structure (references/ and commands/ directories) than the one proposed here (docs/scenarios/ and docs/standards/). Preserved for historical reference." related_docs: - "./SKILL.md" - "./references/python-development-orchestration.md" --- # Reference Document Architecture ## Executive Summary This document defines the complete reference document structure for the opinionated-python-development skill implementing Claude Code progressive disclosure pattern to optimize token usage while maintaining comprehensive guidance. The architecture follows three-level loading: - Level 2 (SKILL.md) core orchestration logic and decision trees - Level 3 (Reference Documents) deep content loaded on-demand Key Design Principles: - Progressive disclosure minimize token consumption - Modular architecture enable independent framework updates - Scenario-specific loading only relevant content accessed - Token budget management estimated sizes and optimization strategies - Cross-reference integrity bidirectional linking with validation - Version independence documents evolve independently --- ## 1.

Content Update Strategy ### 6.1 Version Management **Document Versioning**: - Each document has independent version in frontmatter - Follows semantic versioning (MAJOR.MINOR.PATCH) - MAJOR: Breaking changes to document structure/requirements - MINOR: New content additions examples patterns - PATCH: Clarifications typo fixes formatting **Skill Versioning**: - Skill has overall version in metadata.json - Skill version bumps when multiple documents updated - Skill MAJOR bump: Breaking changes to core requirements - Skill MINOR bump: New scenarios/frameworks added - Skill PATCH bump: Documentation improvements **Example**: ```yaml # In docs/scenarios/cli-human-facing.md --- version: "1.2.0" # Document version --- # In metadata.json { "version": "1.5.0", # Skill version } ``` ### 6.2 Update Triggers **MUST Update Document When**: 1. Python version support changes (e.g. Python 3.15 released) 2. Framework version requirement changes (e.g. Typer 0.20 released) 3. Tool version updates with breaking changes 4. Standards change based on new PEPs 5. Validation discovers broken examples **SHOULD Update Document When**: 1. New patterns discovered in usage 2. Common pitfalls identified 3. Better examples created 4. User feedback suggests improvements **MAY Update Document When**: 1. Formatting improvements possible 2. Diagrams can be enhanced 3. Cross-references can be optimized ### 6.3 Deprecation Workflow **Deprecating a Requirement**: 1. Add deprecation notice to document (90 days before removal) 2. Update examples to show new pattern 3. Provide migration guide 4. Bump document MINOR version 5. After 90 days: Remove deprecated content bump MAJOR version **Example**: ````markdown ## Legacy Pattern (DEPRECATED) > **Deprecation Notice**: This pattern is deprecated as of 2025-10-21 and will be removed in version 2.0.0 (estimated 2026-01-21). > > **Reason**: Python 3.11+ native generics replace legacy typing imports. > > **Migration**: See [Modern Pattern](#modern-pattern) below. ### Deprecated Code \```python from typing import List, Dict # DEPRECATED \``` ## Modern Pattern (CURRENT) \```python # Use native generics (Python 3.11+) def process(items: list[str]) -> dict[str, int]: pass \``` ```` ### 6.4 Dependency Tracking **Document Dependencies** (in frontmatter): ```yaml related_docs: - @docs/standards/type-hints.md - @docs/frameworks/typer-rich/standards.md dependencies: - typer>=0.19.2 - ruff - mypy python_versions: [3.11, 3.12, 3.13, 3.14] ``` **Update Propagation**: - When type-hints.md updates all documents listing it in related_docs flagged for review - When Python 3.15 releases all documents listing python_versions updated - Automated tool generates "Needs Review" report **Dependency Update Tool**: ```python #!/usr/bin/env python3 """Track document dependencies and flag updates.""" from pathlib import Path import yaml def extract_dependencies(doc_path: Path) -> dict: """Extract dependencies from document frontmatter.""" content = doc_path.read_text() # Extract YAML frontmatter if content.startswith('---'): end = content.find('---', 3) if end > 0: frontmatter = yaml.safe_load(content[3:end]) return frontmatter return {} def find_dependent_documents(target_doc: Path, skill_root: Path) -> list[Path]: """Find all documents that depend on target document.""" dependents = [] for doc_path in skill_root.rglob("*.md"): deps = extract_dependencies(doc_path) related = deps.get('related_docs', []) # Check if target_doc in related_docs target_ref = str(target_doc.relative_to(skill_root)) if f"@{target_ref}" in ' '.join(related): dependents.append(doc_path) return dependents # Usage: When updating type-hints.md find all dependents # Generate review checklist for each dependent ``` --- ## 7.
