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.

Cursor is the best place to plan a refactor. Aider is the best place to execute it from a terminal with cheap models and atomic git commits. This guide shows the exact pipe: dump the Cursor chat to markdown, hand it to Aider as a read-only context file, and run an architect/editor split that finishes the work.

Build a project-scoped Claude Code subagent that drives Playwright in a real browser, scoped to its own MCP server so the main session never sees the 25 browser_* tools. Covers the .claude/agents/browser-tester.md frontmatter, mcpServers inline definition, allowed tool list, isolation: worktree, the Playwright Test Agents init flow, and the Sonnet-vs-Haiku model choice.

Turn the unwritten rules in your repo into a SKILL.md that GitHub Copilot loads on demand. Frontmatter, descriptions that route, file references, and how to verify it actually fires.

Claude Code v2.1.128 (May 4, 2026) ships --plugin-dir support for .zip archives, makes EnterWorktree branch from local HEAD, and stops the CLI from leaking its own OTLP endpoint into Bash subprocesses.

Wire an EF Core 10 DbContext into a Model Context Protocol server so Claude Code, Cursor, or any compliant client can run safe, scoped queries against your database. Covers IDbContextFactory lifetime, read-only projections, schema discovery tools, AsNoTracking, parameterised filters, row-level scoping, and the destructive-tool gates you need before letting an agent touch UPDATE.

Claude Code v2.1.126 ships claude project purge, a new CLI subcommand that deletes every transcript, task, file-history entry, and config block tied to a project path in a single shot. Includes --dry-run, --yes, --interactive, and --all.

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.

Claude Code v2.1.122 adds the ANTHROPIC_BEDROCK_SERVICE_TIER environment variable, sent as the X-Amzn-Bedrock-Service-Tier header. Set it to flex for a 50 percent discount on agent calls or priority for faster responses, without touching SDK code.

cowork-terminal-mcp v0.4.1 bridges Claude Cowork's sandboxed VM to your host shell. One tool, stdio transport, hard-pinned Git Bash on Windows.
