Why Harness Engineering?

You've probably hit this wall: every time you open a new Claude conversation, it has no idea what your project is, what tech stack you're using, or what conventions you follow. You spend the first few minutes re-explaining, or you maintain an ever-growing CLAUDE.md as a band-aid.

This isn't an AI capability problem — it's an information structure problem.

Harness Engineering is a documentation methodology built specifically to solve this. The core idea: instead of feeding AI context ad hoc each session, structure your project knowledge once so AI can access it at the right depth at any time.


What Do the Three Skills Do?

Step 1 — Create AGENTS.md and Knowledge Base Structure

Scans your existing codebase and auto-generates AGENTS.md (an AI-readable project directory index) and a docs/ knowledge base skeleton. This is the foundation — all subsequent Skills build on it. Run once, benefit permanently.

Step 2 — Fill the docs/ Knowledge Base

With the skeleton from Step 1 in place, this Skill deeply analyzes each module's architecture decisions, technical conventions, and interface contracts — converting the tacit knowledge scattered across your code into structured documentation that AI can read directly. This is the step that makes AI truly understand your project.

Step 3 — Cross-Session State Management

Creates tasks.json (task list), progress.md (progress log), and init.sh (environment initialization script). Solves the "AI starts from zero every session" problem — next time you open a conversation, run init.sh and the AI immediately knows where you left off and what comes next.


Who Is This For?

  • Developers using Claude Code long-term on the same project
  • Engineers who need AI help maintaining complex codebases
  • Teams where multiple people use AI assistance on the same project

The three Skills work best used in sequence, but each can also be run independently.
