How to Structure a Monorepo So Claude Code's Context Stays Small

A 2026 playbook for keeping Claude Code's 200k token context lean in a monorepo: launch from the subtree you are touching, split CLAUDE.md into nested files that load on demand, push path-scoped rules into .claude/rules/, use skills and subagents for the noisy reads, and exclude other teams' files with claudeMdExcludes. Anchored to Claude Code 2.1.x, claude-sonnet-4-6, and claude-opus-4-7.

How to Cache Multi-Turn Claude Conversations Across API Calls

Place rolling cache_control breakpoints across messages, respect the 20-block lookback, and refresh the 5-minute TTL automatically so a 50-turn agent loop pays the prefix once, not fifty times. Verified against anthropic 0.42 (Python) and @anthropic-ai/sdk 0.30 (Node) in May 2026.

How to Set Up an LLM-as-Judge Eval Harness for a Coding Agent

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.

GitHub Copilot Drops Claude Sonnet 4 From Every Surface

GitHub deprecated claude-sonnet-4 on May 6, 2026 across Copilot Chat, inline edits, ask and agent modes, and code completions. Recommended migration target is Claude Sonnet 4.6. What to grep for in your repo before the next pinned model selection silently breaks.

How to Pipe Cursor's Context to an Aider Session for Multi-Agent Refactors

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.

How to Write a Claude Code Subagent That Runs Browser Tests

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.
