Do Not Compact — Development skill for Claude Code

Don't Compact CLAUDE.md

Claude Code plugin that reloads CLAUDE.md files into context after conversation compaction.

Problem

When Claude Code compacts the conversation to stay within context limits, the contents of CLAUDE.md files (user instructions, project rules, git conventions, etc.) may be lost or summarized. This can cause Claude to forget important rules like commit message conventions or coding standards.

Solution

This plugin hooks into the `SessionStart` event with a `compact` matcher. After compaction, it collects all CLAUDE.md files from the directory hierarchy and injects them back into context as `additionalContext`.

Files collected (in order):

1. ~/.claude/CLAUDE.md (user global instructions)
2. ~/CLAUDE.md and parent directories up to cwd (project hierarchy)

Installation

Plugin install (recommended)

Install in two commands from inside a Claude Code session:

**1. Register the marketplace**

/plugin marketplace add coo-quack/claude-code-marketplace

**2. Install the plugin**

/plugin install do-not-compact@coo-quack

Done. The hooks are enabled automatically.

**Keeping up to date:** Third-party marketplaces have auto-update disabled by default. To receive automatic updates, run `/plugin` → **Marketplaces** tab → select the marketplace → **Enable auto-update**. You can also update manually from the same tab. See [Discover and install plugins](https://docs.anthropic.com/en/docs/claude-code/discover-plugins) for details.

npm install

Install globally via npm and configure hooks manually:

npm install -g @coo-quack/do-not-compact

Update to the latest version:

npm update -g @coo-quack/do-not-compact

Then add to `~/.claude/settings.json`:

{
  "hooks": {
    "SessionStart": [
      {
        "matcher": "compact",
        "hooks": [

            "type": "command",
            "command": "\"$(npm root -g)/@coo-quack/do-not-compact/hooks/rel
