- Added comprehensive tests for buildIterationContext() (both refiners) - Added tests for serialization edge cases - Added tests for deserializeAnalysis() error path - Added tests for prompt construction (convergence and refinement) - Added tests for truncateForPrompt() utility - Added nil artifact error path tests for Refine() methods - All tests are fixture-based and run without ANTHROPIC_API_KEY Coverage improvements: - analysis_refiner.go: 85.3% (buildIterationContext 0%->100%, truncateForPrompt 66.7%->100%, serializeAnalysis 72.5%->95%, deserializeAnalysis 0%->100%) - assessment_refiner.go: 73.1% (buildConvergencePrompt 0%->100%, buildRefinementPrompt 0%->100%) - Overall refiner coverage: 79.96% (exceeds 60% target) Addresses vc-ckef acceptance criteria #1, steveyegge#4, steveyegge#5, steveyegge#6

Summary
This PR introduces support for custom Anthropic API endpoints by adding a centralized client creation utility that respects the
ANTHROPIC_BASE_URLenvironment variable. This enables VC to work with Anthropic-compatible APIs, custom deployments, or alternative endpoints while maintaining backward compatibility.Key Changes
New Utility Function
NewAnthropicClient()ininternal/ai/utils.gothat:ANTHROPIC_BASE_URLenvironment variable for custom endpointsRefactored Client Instantiation
Replaced direct
anthropic.NewClient()calls with the new utility in:internal/ai/supervisor.go- AI supervision functionalityinternal/discovery/sdk/ai.go- AI discovery SDKinternal/executor/agent.go- Agent loop detectioninternal/executor/executor.go- Auto-commit message generationinternal/repl/conversation_state.go- REPL conversation handlinginternal/health/model_*_test.go- Test files for model cost/qualityBenefits
Usage
To use with a custom endpoint:
If
ANTHROPIC_BASE_URLis not set, the client will use the default Anthropic API endpoint.Testing
This enhancement makes VC more adaptable to different deployment scenarios and enables integration with custom AI infrastructure while maintaining simplicity for standard use cases.
