[github-actions]

Summary

Update the indirect dependency github.com/anthropics/anthropic-sdk-go from v1.22.0 to v1.26.0. This SDK is used by the Claude engine integration.

Current State

• Package: github.com/anthropics/anthropic-sdk-go
• Current Version: v1.22.0
• Proposed Version: v1.26.0
• Dependency Type: Indirect (// indirect in go.mod)
• Update Type: Multi-version minor jump (v1.22.0 → v1.26.0, skips v1.23.x, v1.24.x, v1.25.x)

Why Separate Issue

⚠️ Multi-version minor jump with new features

• Jumps 4 minor versions (v1.22.0 → v1.26.0)
• Adds new API features including top-level cache control (automatic caching)
• Adds BetaToolRunner for automatic tool use loops
• Each intermediate version may introduce API additions or behavior changes
• Needs careful testing of the Claude engine integration

Safety Assessment

⚠️ Requires careful review

• Multi-version jump increases cumulative risk across all intermediate releases
• New features (BetaToolRunner, automatic caching) may affect Claude engine behavior
• Review all intermediate changelogs: v1.23.0, v1.24.0, v1.25.0, v1.25.1, v1.26.0
• Test Claude engine workflows thoroughly after update

Changes (latest release v1.26.0)

• Added top-level cache control (automatic caching)
• Added BetaToolRunner for automatic tool use loops
• Various codegen-related updates across intermediate versions

Recommended Action

go get github.com/anthropics/anthropic-sdk-go@v1.26.0
go mod tidy

Testing Notes

• Run all tests: make test-unit
• Test Claude engine workflows end-to-end
• Verify message streaming still works correctly
• Check tool use / function calling behavior
• Verify no regressions in Claude-based agentic workflows
