[1.5.0] - 2026-04-18

Multi-language project support: languages: list in lao.config.yaml for full-stack projects (e.g., [python, react])
Auto-detection now collects all matches (a repo with pyproject.toml + package.json with react → [python, react])
React/TypeScript language pack for all 4 language-aware skills (coding-standards, testing-conventions, code-review, security)
React-specific references: component patterns, hooks, error boundaries, Vitest/React Testing Library, ESLint/Prettier/TypeScript config, XSS prevention, auth token handling, protected routes
Detection heuristic: package.json with react dependency or next.config.* → react
React/TS column added to coding-standards naming conventions table

Config accepts both languages: [python, react] (list) and language: python (backward compatible string)
validate-project-skills.sh parses both languages: list and language: string formats
validate-plugin.sh EXPECTED_REFS expanded from 35 to 42 entries (+ 7 React pack files)
All 4 language-aware SKILL.md files updated: multi-language guidance ("apply each pack to files of its language")
Manifest display changed from Language: to Languages: to reflect multi-language support
README, design spec, and config examples updated for multi-language and React/TypeScript support

Multi-language support: coding-standards, testing-conventions, code-review, and security skills now support Python, Java, and C# via language packs
Universal (language-agnostic) SKILL.md and checklists for all 4 language-aware skills
Language-specific reference packs under references/python/, references/java/, references/csharp/ for each skill
language field in lao.config.yaml for explicit language configuration
Auto-detection of project language from build files (pyproject.toml, pom.xml, *.csproj, etc.)
Language detection integrated into lao/SKILL.md pipeline start and lao-setup/SKILL.md project scan
Language field validation in validate-project-skills.sh
Multi-Language Support section in README and design spec

coding-standards/SKILL.md rewritten as language-agnostic (universal principles only)
testing-conventions/SKILL.md rewritten as language-agnostic (universal principles only)
code-review/SKILL.md updated to reference language-specific code standards
security/SKILL.md updated to reference language-specific checklists and examples
Universal checklists extracted for all 4 skills (language-agnostic items only)
validate-plugin.sh EXPECTED_REFS expanded from 11 to 35 entries (universal + 3 language packs × 4 skills)
Manifest presentation now includes detected language

Phase 6 (Plan) now includes no-placeholder rule, self-review checklist, and structured task templates
Phase 7 (Implement) now includes strict TDD discipline (red-green-refactor with verification), two-stage review (spec compliance + code quality), and systematic debugging protocol
Phase 8 (Validate) now includes rationalization prevention and structured evidence requirements
Phase 9 (Ship) now includes 4 structured completion options (PR, merge, keep, discard)
Simplified lao/SKILL.md — single workflow path

Dual command registration (full name + /lao alias) for all orchestrator commands
CONTRIBUTING.md, CODE_OF_CONDUCT.md, SECURITY.md
Expanded .gitignore for common development artifacts

Initial plugin structure with 13 skills (3 commands + 10 roles)
Validation scripts: validate-plugin.sh, validate-project-skills.sh, check-consistency.sh
Bats test suite with 21 tests
Support for both Claude Code and Cursor platforms
Config-based (lao.config.yaml) and convention-based project skill discovery
Cross-role review gates at Phases 1-3
Preview-then-execute model
Design spec and phase output contract
