claude plugins

Personal Claude Code plugins that wrap tools the official LSP plugins don't cover. Split into small, composable pieces so you can mix-and-match LSP and post-edit behavior.

Plugins

Plugin	Type	What it does
ruff-hooks	hook	Autofix + format Python on every edit; surface remaining ruff diagnostics on stderr
ruff-lsp	LSP	Register ruff server as the Python LSP
pylsp	LSP + hook	Register python-lsp-server + pylsp-mypy as the Python LSP; mypy-on-edit fallback hook
shuck	LSP + hook	Lint + autofix .sh/.bash/.zsh on every edit; register shuck server LSP

Setup matrix

The Python plugins compose, but ruff-lsp and pylsp are mutually exclusive — both claim python as their LSP and the harness only routes a language to one server.

Want	Enable	Skip
Ruff only — lint + format, no type-checking	ruff-hooks + ruff-lsp	pylsp
Ruff + mypy types via pylsp (recommended)	ruff-hooks + pylsp	ruff-lsp
Just autofix-on-edit, no LSP	ruff-hooks	ruff-lsp, pylsp
Ruff LSP only, no autofix-on-edit	ruff-lsp	ruff-hooks

If you enable an LSP that surfaces ruff diagnostics (either ruff-lsp, or pylsp with its bundled pylsp_ruff plugin enabled), set RUFF_HOOK_NO_DIAGNOSTICS=1 in your shell so ruff-hooks skips its diagnostic-emit step. The autofix + format steps still run; only the duplicate diagnostic pass is suppressed.

How they work

Each plugin ships one or both of:

1. A PostToolUse hook that fires after Edit / Write / MultiEdit / NotebookEdit — reads the edited file path from the tool payload, runs the relevant tool, and emits any remaining diagnostics on stderr so Claude can iterate.
2. A .lsp.json registering an LSP server for the relevant language.

The ruff-hooks, ruff-lsp, and pylsp plugins each ship a thin wrapper in bin/ that resolves the underlying tool at runtime:

• prefer command -v <tool> on PATH (with a self-recursion guard)
• else walk up from cwd looking for .venv/bin/<tool> (per-project venv)
• else ~/.venv/bin/<tool> (global venv fallback)

Both the .lsp.json and the hooks invoke the wrapper, so resolution is consistent and survives the harness running with a stripped PATH.

Install (persistent, via the local marketplace)

This directory ships its own marketplace manifest at .claude-plugin/marketplace.json (id: georgeharker). Register it as a local marketplace and install the combo you want — no git remote required:

claude plugin marketplace add ~/Development/claude
# Recommended combo (ruff + mypy via pylsp):
claude plugin install ruff-hooks@georgeharker
claude plugin install pylsp@georgeharker
claude plugin install shuck@georgeharker

To pull in plugin edits without bumping versions: claude plugin marketplace update georgeharker. To uninstall: claude plugin uninstall <name>.

Install (per-session, ad-hoc)

claude --plugin-dir ~/Development/claude/ruff-hooks \
       --plugin-dir ~/Development/claude/pylsp \
       --plugin-dir ~/Development/claude/shuck

Going public

Each plugin dir is self-contained (own .claude-plugin/plugin.json, own bin/ wrappers where needed) so each can become its own git repo. Two layouts work:

• Monorepo: keep this top-level directory as one repo. The marketplace manifest with relative ./<dir> sources works identically when added from a local path or a GitHub URL.

  cd ~/Development/claude && git init && git remote add origin <url> && git push -u origin main
  # consumers: claude plugin marketplace add georgeharker/claude-plugins
  

• Per-plugin repos: split each plugin into its own repo, then keep a separate marketplace repo whose marketplace.json uses git URLs instead of relative paths:

  { "source": { "source": "git", "repo": "georgeharker/ruff-hooks" } }
  

  Trade-off: cleaner ownership per plugin, but versioning is now spread across N repos and consumers see N entries.
