Kadmon Harness
Operative layer for Claude Code — hooks, agents, skills, and commands that transform Claude from a reactive assistant into a system that observes, learns, and evolves.
What is this?
Kadmon Harness is infrastructure, not a product. It is a portable set of agents, commands, skills, hooks, and rules that encode how Claude Code should work on any TypeScript or Python project. Built once, carried to every new project via bootstrap. It turns every session into an observable, memorable, self-improving loop.
Language support today: TypeScript/JavaScript and Python.
Instead of asking Claude "please write a test first", you define it in a rule, a hook enforces it, and an agent specializes in it. The next session already knows.
🎯 Mantra
Observe → Remember → Verify → Specialize → Evolve
| Phase | What It Does | Key Components |
|---|
| Observe | Watch every tool call, manage context | observe hooks, /kompact audit, /nexus |
| Remember | Persist sessions, track learned patterns | SQLite, instinct engine, /chekpoint |
| Verify | Tests first, code review, quality gates | /skanner, /chekpoint |
| Specialize | Domain agents, curated skill catalog | 16 agents, 48 skills, /abra-kdabra |
| Evolve | Forge observations into instincts, generate artifacts | /forge, /evolve (step 6 Generate EXPERIMENTAL through 2026-04-28) |
🚀 Install — 5 steps to install everything
Steps 1–3 install the plugin (agents, skills, commands, hooks — 80 %).
Steps 4–5 bootstrap the rules and security permissions (the 20 % Claude Code plugins can't ship: 19 rules, 14 permissions.deny, 9 permissions.allow CORE).
Steps 1–3 · Install the plugin
Open a Claude Code session in any project and run each on its own line:
Step 1 — Register the marketplace
/plugin marketplace add https://github.com/Kadmon7/kadmon-harness.git
Step 2 — Install the plugin
/plugin install kadmon-harness@kadmon-harness
Step 3 — Reload to activate
/reload-plugins
Run /plugin and you'll see kadmon-harness Enabled with 16 agents · 48 skills · 11 commands · 22 hooks live in the session.
Steps 4–5 · Bootstrap rules + permissions
Pick your OS:
🍎 macOS / 🐧 Linux · bash
Step 4 — Clone and build the harness (once per machine)
git clone https://github.com/Kadmon7/kadmon-harness.git ~/projects/kadmon-harness
cd ~/projects/kadmon-harness
npm install && npm run build
Step 5 — Run the installer for your project (once per project · re-run to update)
./install.sh /path/to/your/project
Dry-run first: ./install.sh --dry-run /path/to/your/project
Updating the harness later:
cd ~/projects/kadmon-harness && git pull && npm install && npm run build # refresh clone
./install.sh /path/to/your/project # re-apply per project
🪟 Windows · PowerShell
One-time machine setup (symlinks + script execution won't work without these):
- Settings → Privacy & Security → For Developers → Developer Mode: ON
- In any terminal:
git config --global core.symlinks true
- In PowerShell (one-time, current user scope):
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
Default Windows policy Restricted blocks .ps1 execution with UnauthorizedAccess. RemoteSigned allows local scripts and signed remote scripts. Verify with Get-ExecutionPolicy -Scope CurrentUser.
Step 4 — Clone and build the harness (once per machine)
# Pick any path — examples: C:\projects, C:\Command-Center, $HOME\dev
cd C:\projects
git clone https://github.com/Kadmon7/kadmon-harness.git
cd kadmon-harness
npm install; npm run build
Step 5 — Run the installer for your project (once per project · re-run to update)
.\install.ps1 -TargetPath C:\path\to\your\project
Dry-run first: .\install.ps1 -TargetPath C:\path\to\your\project -DryRun
