Plan for issue #8

[github-actions]

This PR contains a plan for issue #8.

Plan Overview

The plan proposes supporting multiple LLM providers (z.ai, MiniMax, and any OpenAI-compatible API) through the existing Claude Code GitHub Action by using provider-agnostic configuration variables. The key insight is that the anthropics/claude-code-action already supports custom base URLs and models, so we only need to add configuration for provider selection rather than creating provider-specific workflows.

Key Changes:

• Rename ANTHROPIC_BASE_URL → PROVIDER_BASE_URL
• Rename ANTHROPIC_MODEL → PROVIDER_MODEL
• Add backward compatibility fallback
• Create provider setup documentation

This approach is backward compatible and requires no new GitHub Actions or major architectural changes.

Closes #8

❓ Where is this modified?
The env keys of the action cannot be changed since that is what claude relies on.

[github-actions]

You're absolutely right! I apologize for the confusion in the plan.

The plan is misleading here. The env keys (ANTHROPIC_BASE_URL, ANTHROPIC_MODEL) cannot be changed because that's what the claude-code-action expects.

What can be changed are the GitHub repository variable names that populate these values:

env:
  ANTHROPIC_BASE_URL: ${{ vars.PROVIDER_BASE_URL }}  # Was vars.ANTHROPIC_BASE_URL
  ANTHROPIC_MODEL: ${{ vars.PROVIDER_MODEL }}        # Was vars.ANTHROPIC_MODEL

This way:

• Users configure provider-agnostic repository variables (PROVIDER_BASE_URL, PROVIDER_MODEL)
• The workflow still passes them to the action using the expected ANTHROPIC_* keys

I'll update the plan to clarify this distinction.
