davidshaevel-marketplace
Personal multi-agent development plugin providing development conventions, skills, and project templates. Works with Claude Code and OpenAI Codex CLI.
What This Plugin Provides
- Development conventions injected automatically at session start via hook
- Skills for code review resolution, session handoff (cross-agent memory), and project bootstrapping
- Templates for initializing new projects with standard structure
The same conventions, hooks, and skills serve both agents. Claude Code loads them via .claude-plugin/plugin.json; Codex loads them via .codex-plugin/plugin.json (v1.4.0+).
Plugin name: the plugin identifier is davidshaevel-claude-toolkit. It is retained (despite "claude" in the name) for install-command and marketplace-registration stability across both agents. A vendor-neutral rename is a future v2.0.0 consideration.
Installation
Claude Code
# Add as a marketplace
/plugin marketplace add davidshaevel-dot-com/davidshaevel-marketplace
# Install the plugin
/plugin install davidshaevel-marketplace@davidshaevel-claude-toolkit
Codex CLI
v1.4.0 status: foundational support only. This release ships the Codex-side infrastructure — .codex-plugin/plugin.json manifest, hooks/hooks-codex.json (uses Codex-canonical $PLUGIN_ROOT), shared conventions/development-standards.md, and shared skills/. Remote git-source marketplace install is not yet working because two architectural changes are required:
- Plugin layout. Codex's local source resolver rejects entries that resolve to the marketplace root; the plugin needs to live in a
./plugins/<plugin-name>/ subdirectory per the Codex plugin-json-spec. Our current repo uses a root layout (which Claude Code supports natively).
- Skill path resolution. Several skills (
backup-local-config, session-handoff backup step) invoke scripts via ${CLAUDE_PLUGIN_ROOT}/scripts/.... In a Codex session that variable is not populated; the commands fail. Need to make skill path resolution agent-agnostic (or detect $PLUGIN_ROOT first).
Both blockers are tracked in TT-393 — v1.5.0 Codex remote git-source marketplace install support.
For now (v1.4.0): if you want to experiment with the plugin in Codex, clone the repo locally and register a personal-marketplace entry pointing at the local path (Codex's ~/.agents/plugins/marketplace.json). When the SessionStart hook fires for the first time, Codex will surface a trust prompt — accept it to enable conventions/development-standards.md injection. Skills that don't depend on ${CLAUDE_PLUGIN_ROOT} (resolve-code-review, bootstrap-project) work; skills that do (backup-local-config, session-handoff backup step) won't until v1.5.0.
For full multi-agent install parity: track TT-393. v1.5.0 will restore the remote git-source install path ([marketplaces.davidshaevel-marketplace] source_type = "git" in ~/.codex/config.toml) once the architectural work lands.
Skills

resolve-code-review | Read PR feedback, fix or decline each item, reply in threads, post summary |
session-handoff | Read/write SESSION_LOG.md for cross-agent memory persistence |
backup-local-config | Back up gitignored local files to Google Drive via rclone |
bootstrap-project | Initialize new projects with CLAUDE.md, .cursorrules, CLAUDE.local.md, SESSION_LOG.md |
Commands
| Command | Description |

Updating the Plugin
After pushing a new version to the repository, three locations must be updated for Claude Code to load the new version.
1. Marketplace directory
The marketplace directory is a git clone that needs to be pulled:
git -C ~/.claude/plugins/marketplaces/davidshaevel-marketplace pull origin main
2. Plugin cache
The cache stores versioned clones at ~/.claude/plugins/cache/davidshaevel-marketplace/davidshaevel-claude-toolkit/<version>/. Create a new directory for the new version:
# Clone the new version tag into the cache
git clone --branch v<NEW_VERSION> --depth 1 \
[email protected]:davidshaevel-dot-com/davidshaevel-marketplace.git \
~/.claude/plugins/cache/davidshaevel-marketplace/davidshaevel-claude-toolkit/<NEW_VERSION>
# Optionally recreate the old version directory from its tag (keeps it clean)
rm -rf ~/.claude/plugins/cache/davidshaevel-marketplace/davidshaevel-claude-toolkit/<OLD_VERSION>
git clone --branch v<OLD_VERSION> --depth 1 \
[email protected]:davidshaevel-dot-com/davidshaevel-marketplace.git \
~/.claude/plugins/cache/davidshaevel-marketplace/davidshaevel-claude-toolkit/<OLD_VERSION>
3. Installed plugins registry
