Claude Code Course

6 months ahead, in a few hours.

Ship in a day what your teammates ship in a week. It's not magic, it's a system. It's called harness engineering.

Six layers, one loop.

The harness is the layer wrapped around the model: hooks, permissions, tools, memory. It is what separates an LLM that answers from a real collaborator. We show you, layer by layer, how to set it up on your codebase in one afternoon.

HARNESS · 6 LAYERS EN · 2026
  1. INPUT

    Intent

    Translate a human need into a clear contract for the machine. No hacked prompts, briefs that hold up.

    • Canonical brief
    • Acceptance criteria
    • Doubt protocol
  2. MEMORY

    Context

    Give Claude the same view you have: codebase, tickets, conventions, past decisions. A million tokens, well spent.

    • CLAUDE.md
    • Semantic index
    • Decision log
  3. MCP

    Tooling

    Wire up the systems that matter: Jira, GitHub, staging database, Linear, Figma.

    • MCP servers
    • Scoped auth
    • Audit trail
  4. SKILLS

    Skills

    Skills = activatable know-how. A style, a procedure, a coded checklist. You pick the mode, not the words.

    • feature-dev
    • deep-review
    • post-mortem
    • ops
  5. HOOKS

    Guardrails

    Every Claude keystroke, a hook verifies. Lint, tests, types, security policy. Error → Fix

    • pre-tool
    • post-edit
    • pre-commit
    • policy
  6. SHIP

    Shipping

    Signed PR, changelog written, ticket closed. The loop closes on itself.

    • Draft PR
    • Auto changelog
    • Deploy preview
