francylisboacharuto bac2b27bb8 feat: v4.0 Cross-Platform Modernization — Agent Skills Open Standard compliance 
BREAKING CHANGES:
- Remove -cskill suffix from all skill names (use standard kebab-case)
- Simplify marketplace.json to only official fields (fixes Issue #5)
- SKILL.md body must be <500 lines (progressive disclosure via references/)

New features:
- Cross-platform support for 8+ platforms (Claude Code, Copilot, Cursor, Windsurf, Cline, Codex CLI, Gemini CLI)
- scripts/install-template.sh: Auto-detect platform installer with --dry-run
- scripts/validate.py: Spec compliance checker for generated skills
- scripts/security_scan.py: Security scanner for hardcoded keys and dangerous patterns
- MIGRATION.md: v3.x to v4.0 migration guide
- 6 new reference files for progressive disclosure from lean SKILL.md

Key changes:
- SKILL.md: 4,116 → 272 lines with spec-compliant YAML frontmatter
- marketplace.json: Stripped to {name, plugins} only
- article-to-prototype-cskill/ → article-to-prototype/
- stock-analyzer-cskill/ → stock-analyzer/
- Export system integrates validation + security scanning
- README.md rewritten for all supported platforms
- Phase 5 pipeline outputs SKILL.md-first, spec-compliant skills

SC-039: Generated Skills Work Across Platforms Without Modification

Covers: FR-028, NFR-001 — Generated skills MUST work on any SKILL.md-standard platform without modification Type: Happy Path

Given

  • A skill has been generated by the meta-skill for "code review automation"
  • The skill uses only standard SKILL.md features (no platform-specific extensions)

When

  • The generated skill directory is copied to:
    • ~/.claude/skills/code-review-automation/
    • .github/skills/code-review-automation/
    • .cursor/rules/code-review-automation/

Then

  • The SKILL.md is valid standard SKILL.md format readable by all platforms
  • No platform-specific hacks or workarounds are present in the files
  • The frontmatter uses only standard fields (name, description, license, compatibility, metadata, allowed-tools)
  • No files reference platform-specific paths or configurations

Verification Method

Method: Automated test

Steps:

  1. Generate a skill using the meta-skill
  2. Parse SKILL.md frontmatter and verify all fields are standard spec fields
  3. Grep for platform-specific strings: grep -r "claude-code\|copilot\|cursor" code-review-automation/SKILL.md
  4. Verify no platform-specific conditional logic in SKILL.md body

Expected evidence: SKILL.md frontmatter contains only standard fields. No platform-specific strings in SKILL.md body. The skill is a pure standard SKILL.md that any compliant platform can read.
