|

|

This PR adds ${platformName} support while maintaining existing ${otherPlatform} functionality, making this skill/extension work on both platforms.
|
||||
|
||||
## Changes
|
||||
|
||||
${targetPlatform === 'gemini' ? `
|
||||
- Added \`gemini-extension.json\` - Gemini CLI manifest
|
||||
- Added \`GEMINI.md\` - Gemini context file
|
||||
- Created \`shared/\` directory for shared documentation
|
||||
- Transformed MCP server paths for Gemini compatibility
|
||||
- Converted tool restrictions (allowed-tools → excludeTools)
|
||||
- Inferred settings schema from environment variables
|
||||
` : `
|
||||
- Added \`SKILL.md\` - Claude Code skill definition
|
||||
- Added \`.claude-plugin/marketplace.json\` - Claude plugin config
|
||||
- Created \`shared/\` directory for shared documentation
|
||||
- Transformed MCP server paths for Claude compatibility
|
||||
- Converted tool restrictions (excludeTools → allowed-tools)
|
||||
- Documented environment variables from settings
|
||||
`}
|
||||
|
||||
## Benefits
|
||||
|
||||
- ✅ Single codebase works on both AI platforms
|
||||
- ✅ 85%+ code reuse (shared MCP server and docs)
|
||||
- ✅ Easier maintenance (fix once, works everywhere)
|
||||
- ✅ Broader user base (Claude + Gemini communities)
|
||||
|
||||
## Testing
|
||||
|
||||
- [x] Conversion validated with skill-porter
|
||||
- [x] Files meet ${platformName} requirements
|
||||
- [ ] Tested installation on ${platformName}
|
||||
- [ ] Verified functionality on both platforms
|
||||
|
||||
## Installation
