Learn AI agents from the inside out. MicroAgent shows you the agent loop, tool calls, planning, memory, and multi-agent coordination — the parts every other AI app hides behind a chat box. This is not another chatbot. It is a 12-lesson visual course that breaks down how a real AI agent runtime is built, from a minimal loop with one tool to a full multi-agent team with task isolation. WHY MICROAGENT • See inside every step: messages, tool calls, plans, task state, memory, collaboration • Replayable demos: deterministic scenarios you can run again and again • Source code you can follow: each lesson maps to real Swift / Python code • 12 lessons that build on each other, not 50 random tips • Built for iPhone and iPad, fully offline-readable • One-time purchase, no subscription WHAT YOU WILL LEARN ① s01 The Agent Loop — a minimal agent with a single bash tool, end to end ② s02 Tools — read, write, edit, bash; how a tool registry actually works ③ s03 TodoWrite — make the agent plan before it acts ④ s04 Subagents — isolate work and avoid context pollution ⑤ s05 Skills — load knowledge on demand with SKILL.md ⑥ s06 Compact — keep the context window healthy with summarization ⑦ s07 Tasks — file-backed task system with dependencies ⑧ s08 Background Tasks — long-running work without blocking the loop ⑨ s09 Agent Teams — multi-agent coordination via JSONL inbox ⑩ s10 Team Protocols — shutdown, plan approval, request-response patterns ⑪ s11 Autonomous Agents — idle-loop teammates that auto-claim tasks ⑫ s12 Worktree + Task Isolation — parallel execution with shared task board WHO IT IS FOR ① iOS / Swift / full-stack developers ready to move from "use AI" to "build agents" ② AI and LLM self-learners who have read about ReAct, reflection, tool calling and want to see them run ③ Tech leads, PMs and indie builders who need a real mental model of agent architecture, not just prompt tricks HOW IT IS DIFFERENT • Visual breakdown of every step — not another chat interface. See the agent loop, planning, memory and coordination in action. • Learn from deterministic demos — run the same scenario repeatedly and understand each step. • Engineering patterns for real agent systems — not just prompting tricks. • Built-in code visualization — each lesson maps directly to runnable Swift and Python source.
