Makes KeiSeiKit installable both as classic kit AND as an
Anthropic Claude Code plugin.
.claude-plugin/plugin.json — plugin manifest (name, version,
description, author OBJECT per schema, repository, license)
.claude-plugin/marketplace.json — own marketplace declaration
(owner OBJECT per schema, plugins[].source OBJECT)
.claude-plugin/mcp-template.json — template for .mcp.json (actual
.mcp.json write is blocked by hook; user copies template manually)
PLUGIN.md — dual-install docs (plugin vs classic)
hooks/hooks.json — uses ${CLAUDE_PLUGIN_ROOT} (per Anthropic
schema, NOT ${PLUGIN_ROOT}); wraps hooks under top-level
"hooks": {...} key
Schema corrections caught during agent validation:
- marketplace.json owner MUST be object (not string)
- hooks.json requires "hooks": {...} top-level wrapper
- env var is ${CLAUDE_PLUGIN_ROOT} not ${PLUGIN_ROOT}
Companion edits in install-split bundle: install/lib-args.sh
gains an 8-line plugin-first banner in print_help() directing
users toward the plugin install path as recommended default.
Dual-install strategy: users can pick
- `claude plugin marketplace add <url>` then install — latest
and iteration-friendly (this PR enables it)
- classic ./install.sh — legacy kit path, full 37-primitive
control
