THE AGENTIC CODING FIELD GUIDE / FINAL MERGED EDITION

Understand the code.Behind the agent.

From a Markdown skill to a running worker. A visual, hands-on guide to Claude Code, context budgets, task graphs, AFK execution, and the repositories and toolkits that connect them.

Learn the system

Skills, workflows, subagents, hooks, memory and isolation—without conflating them.

Start with foundations ↗02 /

Inspect the mechanics

Follow concrete files, dispatch instructions, subprocesses, reports and checkpoints.

Open the repository field guide ↗03 /

Build a small version

Copy a skill, test a hook, run a local scheduler demo, then add only what you need.

Go to the build laboratory ↗04 /

Choose your toolkit

Compare nine toolkits by what they ship and what they keep in context—then install only what you call.

Runnerwhere it stays alive

A skill is not a daemon. A worktree is not a security sandbox. Background is not the same as cloud. Each solves a different problem.

What was consolidated—and what changed

Three uploads fed this edition. Your two masterclass files are byte-for-byte identical: this edition uses that shared masterclass as its source and preserves its original chapters in the source archive. The third, the nine-toolkit guide, is now merged into live chapters: a context-budget foundation, spec-driven frameworks, a toolkit comparison with its overload check, and a load-only-what-you-call setup.

From your uploads Foundational explanations, beginner exercises, toolkit comparisons and repository framing. External recheck Selected official documentation and source files. Teaching model New diagrams, simulations and example code—not undocumented product guarantees.

Reviewed 27 September 2026; updated 3 October 2026 for Claude Code v2.1.289 (AGENTS.md, mods, plugin marketplaces, prompt audit and evals). Live default-branch links can change. This file does not execute real agents, access your accounts, or send telemetry.
