ci: run Claude Code workflow on Fable 5

[loothero]

Summary

• Set model: "claude-fable-5" on the anthropics/claude-code-action step in .github/workflows/claude.yml, so @claude mentions on issues and PRs are handled by Claude Fable 5 (Anthropic's most capable model) instead of the action's default (Opus 4.8).
• Replaced the stale commented-out example (claude-opus-4-20250514, a deprecated model ID) with the explicit model setting.

Notes

• Fable 5 is priced at $10/$50 per MTok (input/output) vs Opus 4.8's $5/$25 — the increased API cost is expected and accepted.
• No other workflow behavior changes (triggers, permissions, and auth via CLAUDE_CODE_OAUTH_TOKEN are untouched).

• Provide comprehensive feedback

Review Feedback

✅ Overall Assessment: APPROVED

This is a well-executed configuration update that achieves its stated goal of upgrading to Claude Fable 5. The changes are minimal, focused, and properly documented.

Code Quality & Best Practices

• Excellent: Clear, descriptive comment explaining the model choice on .github/workflows/claude.yml:43-44
• Good: Maintains consistent YAML formatting and indentation
• Good: Follows the action's documented parameter naming conventions

Security & Configuration

• ✅ Secure: Uses proper secret reference (CLAUDE_CODE_OAUTH_TOKEN) without exposing credentials
• ✅ Permissions: Workflow permissions remain unchanged and appropriate (read-only access)
• ✅ Model ID: "claude-fable-5" is a valid, current model identifier

Potential Considerations

• Cost Impact: As acknowledged in the PR description, Fable 5 is 2x more expensive than Opus 4.8 ($10/$50 vs $5/$25 per MTok). This is documented and accepted.
• Performance: Fable 5 should provide better code analysis quality, justifying the cost increase for code reviews

Technical Implementation

• Clean Change: Replaces outdated commented example with active configuration
• No Breaking Changes: All other workflow behavior remains identical
• Backward Compatible: Action version @beta supports the Fable 5 model

Minor Suggestions

1. Consider monitoring usage costs after deployment to validate the ROI
2. The extensive commented examples (lines 46-64) are helpful for future customization

Verification

• Workflow syntax is valid YAML
• All required parameters are present
• Trigger conditions remain unchanged
• No security vulnerabilities introduced

Summary

This PR successfully implements the intended upgrade to Claude Fable 5 with no issues identified. The implementation is clean, well-documented, and maintains all existing functionality while providing access to Anthropic's most capable model.
