claudespace

Personal Claude Code plugin marketplace — one catalog for all your self-authored and curated third-party skills, with exact version pinning via git.

What problem does this solve?

Claude Code has two extension mechanisms — skills (flat file copies under ~/.claude/skills/) and plugins (versioned, installed via claude plugin install plugin@marketplace). Managing skills as file copies means you lose track of where they came from, what version they're at, and whether there are upstream updates.

claudespace is a marketplace: a git repo with a .claude-plugin/marketplace.json catalog that tells Claude Code what plugins are available, where their code lives, and the exact commit to install. One claude plugin marketplace add gives you every skill in this catalog. Version bumps are explicit git operations — no silent drift.

Quick Start

# 1. Register this marketplace (once per machine)
claude plugin marketplace add LKCY23/claudespace

# 2. Install any plugin
claude plugin install github@claudespace
claude plugin install deep-research@claudespace

# 3. Install everything
claude plugin install github@claudespace \
  research-brainstorm@claudespace \
  literature-review@claudespace \
  read-paper@claudespace \
  deep-research@claudespace \
  academic-paper@claudespace \
  academic-paper-reviewer@claudespace \
  academic-pipeline@claudespace \
  karpathy-llm-wiki@claudespace

If you use claude-config for cross-machine config sync, you can reference these in plugins.yaml and let claude-config apply handle the installation.

| Plugin | Category | Source | Upstream | |--------|----------|--------|----------| | github | devtools | self-hosted | claude-github-skill | | research-brainstorm | research | self-hosted | research-brainstorm | | literature-review | research | self-hosted | research-reading-skills | | read-paper | research | self-hosted | research-reading-skills | | deep-research | research | third-party | academic-research-skills | | academic-paper | research | third-party | academic-research-skills | | academic-paper-reviewer | research | third-party | academic-research-skills | | academic-pipeline | research | third-party | academic-research-skills | | karpathy-llm-wiki | knowledge | third-party | karpathy-llm-wiki |

Architecture: Two source modes

claudespace supports two plugin source patterns, both defined in marketplace.json:

Mode 1 — Self-hosted (submodule)

The plugin code lives directly in this repository via git submodule. The version is determined by the submodule's pinned commit.

claudespace/
└── skills/
    └── github/              ← git submodule @ commit 8ba6659
        └── SKILL.md

{ "name": "github", "source": "./skills/github" }

Used for: plugins you own — github, research-brainstorm, literature-review, read-paper.

Mode 2 — External reference (pinned sha)

The plugin code lives in an external repository. The version is locked to an exact commit sha.

{
  "name": "deep-research",
  "source": {
    "source": "git-subdir",
    "url": "https://github.com/Imbad0202/academic-research-skills",
    "path": "skills/deep-research",
    "ref": "main",
    "sha": "57507ef7a0b6828798d5de8f68a08b5943f43a87"
  }
}

Used for: third-party plugins you want to pin — deep-research, academic-paper, academic-paper-reviewer, academic-pipeline, karpathy-llm-wiki.

Why two modes?

| | Mode 1 (self-hosted) | Mode 2 (external) | |---|---|---| | Version tracking | git submodule status | sha field in marketplace.json | | Update mechanism | git submodule update --remote | manually update sha in marketplace.json | | Git history | Full submodule history in this repo | No local copy of upstream code | | Best for | Code you maintain and evolve | Curated third-party snapshots |

Install

# Register marketplace
claude plugin marketplace add LKCY23/claudespace

# Install a specific plugin
claude plugin install <name>@claudespace

# List what's installed
claude plugin list

Update

Update self-hosted plugins (Mode 1)

cd claudespace
git submodule update --remote skills/github        # pull latest from upstream
git add skills/github                              # pin new commit
git commit -m "chore: update github to vX.Y.Z"
git push

# Then tell users to refresh their marketplace cache:
claude plugin marketplace update claudespace
claude plugin update github@claudespace

Update third-party plugins (Mode 2)

# 1. Get the latest commit sha from upstream
gh api repos/Imbad0202/academic-research-skills/commits/HEAD --jq '.sha'

# 2. Edit marketplace.json: update the "sha" field for the plugin

# 3. Review the diff between old and new sha to verify nothing is broken

# 4. Commit and push
git add .claude-plugin/marketplace.json
git commit -m "chore: update deep-research to <new-sha>"
git push

# 5. Users refresh:
claude plugin marketplace update claudespace
claude plugin update deep-research@claudespace

Add a new plugin

Add your own (Mode 1)

# 1. Add as git submodule
git submodule add https://github.com/<you>/<repo>.git skills/<name>

# 2. Add entry to marketplace.json
# {
#   "name": "<name>",
#   "source": "./skills/<name>",
#   "description": "...",
#   "category": "..."
# }

# 3. Commit
git add .gitmodules skills/<name> .claude-plugin/marketplace.json
git commit -m "feat: add <name> plugin"
git push

Curate a third-party (Mode 2)

# 1. Find the repo structure — locate the SKILL.md and note the subdirectory path

# 2. Get the latest commit sha
gh api repos/<owner>/<repo>/commits/HEAD --jq '.sha'

# 3. Add entry to marketplace.json
# {
#   "name": "<name>",
#   "source": {
#     "source": "git-subdir",
#     "url": "https://github.com/<owner>/<repo>",
#     "path": "<subdir>",
#     "ref": "main",
#     "sha": "<commit-sha>"
#   },
#   "description": "...",
#   "category": "...",
#   "author": { "name": "<owner>" }
# }

# 4. Commit
git add .claude-plugin/marketplace.json
git commit -m "feat: add <name> (third-party, pinned to <short-sha>)"
git push

Repository Structure

claudespace/
├── .claude-plugin/
│   └── marketplace.json          ← Plugin catalog (the core of this repo)
├── .gitmodules                   ← Submodule definitions (self-hosted plugins)
├── skills/                       ← Self-hosted skill submodules

Third-party plugins (Mode 2) have no local files in this repo — they are referenced by URL and sha in marketplace.json and fetched on demand by claude plugin install.

Relationship with claude-config

claude-config is a cross-machine configuration sync tool. claudespace is the skill source — it defines what skills exist and at what versions. claude-config is the deployment tool — it applies configurations (including plugin installations) to any machine.

claudespace                     claude-config
  │                               │
  │ marketplace.json  ──ref──→    │ plugins.yaml
  │ (what & which version)        │ (what to install where)
  │                               │
  │  claude plugin install        │  claude-config apply
  │  github@claudespace           │  → calls plugin install
  │                               │

If you use both, reference claudespace plugins in claude-config's plugins.yaml and run claude-config apply — it will handle marketplace registration and plugin installation for you.

Version Policy

All plugins are pinned to exact commits — no automatic tracking of main/latest
Updates are manual and reviewed — before bumping a sha, review the upstream diff to avoid breaking changes
Self-hosted plugins are pinned via submodule commit; git submodule update --remote fetches latest but does not auto-commit
Third-party plugins are pinned via sha in marketplace.json; update requires an explicit edit and commit

This is intentional: a marketplace is a curated catalog, not a firehose. You decide when to upgrade.

License

This repository contains both original work and third-party plugin references. Each self-hosted submodule carries its own license. Third-party plugins referenced in marketplace.json remain under their respective upstream licenses.
