Fix the three failure modes that break Claude agents in production: runaway loops, wrong tool calls, and hallucinated arguments. A practical debugging guide.
Design context for Claude agents: what to keep, what to load on demand, what to leave out, and why cutting content sharpens reasoning and cuts cost.
Context engineering for Claude agents: the least-context principle, what earns a place in the window, what to evict, and compaction for long tasks.
Production guide to connecting MCP servers to Claude: auth at the tool boundary, model-friendly schemas, idempotency, and graceful error handling.
Connect MCP servers to Claude the right way: OAuth, closed schemas, error-as-data recovery, and idempotency keys so your integrations survive production.
Reusable patterns for Claude agents: layered prompts, typed tool contracts, just-in-time context with Skills, plan-then-act, and structured handoffs.
Code-level patterns for structuring Claude agents: frozen prompts, prescriptive tools, programmatic tool calling, and context lifecycle. Build reliable agents.
A hands-on walkthrough: define tools, build the loop, handle failures and idempotency, and ship a Claude agent behind an eval gate.
A step-by-step guide to building a working Claude agent with tool use, the agentic loop, and structured outputs you can ship today. Code included.
