For developers using Claude Code who want to move past trial-and-error.This guide is built from the patterns that actually work when you're:- Running multi-agent workflows in parallel- Managing your context window like a scarce resource- Making fast calls on "should this be inline or dispatched?"- Routing tasks to the right model tier (cheap vs. frontier)- Handling subagent failures gracefullyIt's not tutorial-level. Not "10 tips." It's how someone operates at the edge case of agentic Claude Code — what to do, when to do it, and why.Contents:- Dispatch decision trees (which agent type, when)- Model routing for cost + reasoning (when a cheap model saves tokens, when a frontier model pays for itself) — including a hard sensitivity gate for what never leaves your control- Context economy discipline (11 concrete practices)- 6 reusable prompt templates (research, architecture, code review, data transformation, debugging, escalation) plus a ready-to-paste CLAUDE.md starter-rules set- Output formatting that scales (tables, progress bars, structured thinking)- Risk gates: what needs human confirmation, what you execute autonomously- Real workflow examples with failure/recovery texture (sanitized, generalizable)Full table of contents:1.
