Hierarchical Agent Memory (HAM)

Scoped memory system that gives AI coding agents a cheat sheet for each directory instead of re-reading your entire project every prompt. Root CLAUDE.md holds global context (~200 tokens), subdirectory CLAUDE.md files hold scoped context (~250 tokens each), and a .memory/ layer stores decisions, patterns, and an inbox for unconfirmed inferences.

When to Use This Skill

• Use when you want to reduce input token costs across Claude Code sessions
• Use when your project has 3+ directories and the agent keeps re-reading the same files
• Use when you want directory-scoped context instead of one monolithic CLAUDE.md
• Use when you want a dashboard to visualize token savings, session history, and context health
• Use when setting up a new project and want structured agent memory from day one

How It Works

Step 1: Setup ("go ham")

Auto-detects your project platform and maturity, then generates the memory structure:

project/
├── CLAUDE.md              # Root context (~200 tokens)
├── .memory/
│   ├── decisions.md       # Architecture Decision Records
│   ├── patterns.md        # Reusable patterns
│   ├── inbox.md           # Inferred items awaiting confirmation
│   └── audit-log.md       # Audit history
└── src/
    ├── api/CLAUDE.md      # Scoped context for api/
    ├── components/CLAUDE.md
    └── lib/CLAUDE.md
