Copilot optimizes for keystrokes, Claude Code optimizes for tasks. Which to choose, where each fits, and how they differ on MCP tools, review, cost and governance.
Leaderboards measure someone else's problem. Build a 50-task set from your own traffic, score it blind, price it per task, then keep the swap cheap.
Every long-context release restarts the RAG obituary. Retrieval still wins on cost, freshness, permissions, and citation. The five fixes that rescue a weak pipeline.
The prompt is the smallest part. Production quality comes from context assembly: retrieval scope, ordering, compaction, tool results, and a hard token budget.
