From the README

agent-starter

Skills, hooks, templates, and engineering guides for bootstrapping AI-agent-friendly projects, with a per-project self-improvement loop.

What it is

A toolkit for setting up projects that AI agents can work in safely and productively. It scaffolds new projects, retrofits existing ones, and ships enforcement hooks, drop-in configs, and engineering patterns. The differentiator is the self-improvement loop: scaffolded projects capture signal from their own usage and turn it into better rules over time.

Provenance: patterns marked _"derived from Anthropic's Claude Code source"_ are reverse-engineered from the Claude Code CLI; everything else is added on top. See About.

Quick start

This repo doubles as a Claude Code plugin marketplace. Installing the plugin is the recommended path: it loads every skill and wires the enforcement hooks in one step.

Then run /new-project (new codebase) or /adopt-project (existing one).

Install

Pick the path that matches what you want:

Point an agent at the repo

No install needed. Give an agent the repo URL and it reads the matching entry file and drives the setup interactively (audit-first, opt-in, nothing overwritten):

TEAM.md is the companion to ADOPT.md: where ADOPT.md installs into one developer's ~/.claude, TEAM.md vendors the setup (hooks, shared config, plugin defaults) into the repo itself.

Notes on the plugin and hooks

- The plugin wires five enforcement hooks (file-size, lint-on-edit, silent-error, dangerous-command, codebase-health) plus a /loop instruction-review hook, all from hooks/hooks.json.
- The read-before-edit guard pair is left out of the plugin on purpose (recent Claude Code enforces read-before-edit natively). Opt into it with ./install.sh --with-read-guard.
- install.sh merges its…

How plugins work

  • A plugin bundles slash commands, subagents, skills, hooks, MCP servers and status lines so they install together.
  • Add the marketplace inside Claude Code with /plugin marketplace add sneg55/agent-starter, then run /plugin to pick what to install.
  • You can turn a plugin off again from /plugin without deleting anything.
