# Claude Ecosystem Expansion Foundations

## Purpose

This document captures the architectural foundations adopted in `ai-toolkit` after reviewing:

1. the current toolkit repository,
2. official Claude Code patterns,
3. selected external benchmark repositories.

The outcome is a toolkit that is now positioned as a more modular, Claude-first, benchmark-backed system with stronger lifecycle automation and extension tooling.

## Implemented Foundations

### 1. Plugin-oriented structure

`ai-toolkit` now treats plugin packaging as a first-class capability, with separate runtime-aware surfaces for Claude Code, the Claude Chat/Desktop/Cowork app, and optional global Codex layering.

Implemented artifacts:
- `app/.claude-plugin/plugin.json`
- `app/claude-app/`
- `app/plugins/`
- `app/skills/plugin-creator/SKILL.md`
- `scripts/claude_app.py`
- `kb/reference/plugin-pack-conventions.md`

Claude Code reads filesystem configuration such as `~/.claude/rules` and
`CLAUDE.md`. The Claude app does not scan those locations. For the app,
`ai-toolkit claude-app export --verify` creates an uploadable plugin ZIP and a
separate Cowork global-instructions file. Plugin skills work in Chat and Cowork;
hooks and sub-agents are Cowork-only.

### 2. Broader lifecycle coverage

The toolkit now covers prompt, edit, subagent, compaction, and session-end phases.

Implemented events:
- `SessionStart`
- `Notification`
- `PreToolUse`
- `UserPromptSubmit`
- `PostToolUse`
- `Stop`
- `TaskCompleted`
- `TeammateIdle`
- `SubagentStart`
- `SubagentStop`
- `PreCompact`
- `SessionEnd`

### 3. Creator workflows

The toolkit now includes first-class creator workflows for extension work:
- `hook-creator`
- `command-creator`
- `agent-creator`
- `plugin-creator`

### 4. Benchmark-backed maintenance

External ecosystem research is operationalized through repeatable scripts and machine-readable artifacts.

Implemented artifacts:
- `scripts/benchmark_ecosystem.py`
- `scripts/harvest_ecosystem.py`
- `benchmarks/ecosystem-dashboard.json`
- `benchmarks/ecosystem-harvest.json`
- `kb/reference/claude-ecosystem-benchmark-snapshot.md`

## Benchmark Inputs

The reference benchmark set is intentionally curated:
- `anthropics/claude-code`
- `affaan-m/everything-claude-code`
- `ChrisWiles/claude-code-showcase`
- `disler/claude-code-hooks-mastery`
- `codeaholicguy/ai-devkit`
- `alirezarezvani/claude-code-skill-factory`

## Adopted Outcomes

| Area | Adopted in ai-toolkit |
|------|------------------------|
| Plugin manifests | Yes |
| Claude Chat/Cowork uploadable plugin export | Yes |
| Domain plugin packs | Yes (experimental) |
| Hook creator workflow | Yes |
| Command creator workflow | Yes |
| Agent creator workflow | Yes |
| Plugin creator workflow | Yes |
| Post-edit feedback hooks | Yes |
| Prompt governance hook | Yes |
| Subagent lifecycle hooks | Yes |
| Session-end handoff | Yes |
| Benchmark dashboard JSON | Yes |
| Harvesting workflow | Yes |

## Current Position

`ai-toolkit` is now documented and implemented as a complete, production-ready toolkit baseline rather than a staged roadmap. Future changes should be treated as normal product evolution, not backlog catch-up.
