Feature Request: Add environment variable support for custom GitHub repository configuration

[dobachi]

Summary

Allow users to configure the CLI to use custom GitHub forks of claude-code-templates by setting environment variables, enabling organizations and individuals to maintain their own component repositories.

Use Case

1. Enterprise/Organization Use: Companies can maintain private forks with custom agents, commands, and MCPs tailored to their workflows
2. Community Extensions: Contributors can test their components before submitting PRs
3. Regional Customization: Enable localized or specialized component collections
4. Development/Testing: Easier testing of new components during development

Proposed Solution

Add support for the following environment variables:

Variable	Description	Default
CCT_REPO_OWNER	GitHub owner/organization	davila7
CCT_REPO_NAME	Repository name	claude-code-templates
CCT_REPO_BRANCH	Branch name	main
CCT_COMPONENTS_PATH	Path to components directory	cli-tool/components

Example Usage

# Install agent from custom fork
CCT_REPO_OWNER=myorg CCT_REPO_BRANCH=develop npx claude-code-templates --agent my-custom-agent

# Use organization's private components
export CCT_REPO_OWNER=my-company
export CCT_REPO_NAME=claude-code-templates-enterprise
npx claude-code-templates --agent security-auditor

Scope and Limitations

This implementation is GitHub-specific. The CLI uses:

• raw.githubusercontent.com - For downloading component files
• api.github.com - For listing directory contents (discovering available components)

Support for other Git platforms (GitLab, Bitbucket, self-hosted) would require additional work due to different API endpoints.

Implementation

I have a working implementation ready in my fork:

• Branch: https://github.com/dobachi/claude-code-templates/tree/feature/custom-repository-support
• Commit: dobachi@f12be2a

Files Modified

File	Changes
src/file-operations.js	Add GITHUB_CONFIG with env var support
src/index.js	Add buildGitHubUrl and buildGitHubApiUrl helpers, update all installIndividual* functions
src/sdk/global-agent-manager.js	Same configuration pattern

Key Points

• Replaced all hardcoded GitHub URLs with configurable values
• Added helper functions for consistent URL generation
• Full backward compatibility (defaults to current behavior)
• No breaking changes to existing API
• Simple implementation using only environment variables

Next Steps

I will submit a PR referencing this issue once it's created. Thank you for considering this feature!
