Build a working LLM-as-judge eval harness for a coding agent in Python: golden tasks, deterministic checks, a rubric judge on Claude Sonnet 4.6, calibration against human labels, and a CI gate that fails the build when scores regress.

Wire up anthropics/claude-code-action@v1 so every pull request gets an autonomous Claude Code review with no @claude trigger. Includes the v1 YAML, claude_args for claude-sonnet-4-6 vs claude-opus-4-7, inline-comment tooling, path filters, REVIEW.md, and the choice between the self-hosted action and the managed Code Review research preview.

Stream Claude responses from an ASP.NET Core 11 minimal API end-to-end: the official Anthropic .NET SDK, TypedResults.ServerSentEvents, SseItem, IAsyncEnumerable, cancellation flow, and the gotchas that buffer your tokens silently. With Claude Sonnet 4.6 and Opus 4.7 examples.

Add prompt caching to a Python or TypeScript Anthropic SDK app, place cache_control breakpoints correctly, and read cache_read_input_tokens and cache_creation_input_tokens to compute a real hit rate. With pricing math for Claude Sonnet 4.6 and Opus 4.7.

Three ways to put Claude Code on a schedule that triages GitHub issues unattended in 2026: cloud Routines (the new /schedule), the claude-code-action v1 with cron + issues.opened, and the session-scoped /loop. Includes a runnable Routine prompt, a complete GitHub Actions YAML, jitter and identity gotchas, and when to pick which.

Build a working Model Context Protocol server in C# 14 / .NET 11 using the official ModelContextProtocol 1.2 SDK. Covers stdio transport, [McpServerTool] attributes, dependency injection, the stderr logging trap, and registration with Claude Code, Claude Desktop, and VS Code.
