Claude Hooks Pack · 4 production hooks · copy-paste install

Most people use Claude Code.
Not many build a Claude Code system.

These 4 files are the difference. Copy-paste hooks running in production — not tips, not demos, actual infrastructure.

Every session starts from scratch — context gone
Design tokens change, paired projects break silently

Hooks are Claude Code's most underused feature. Most people don't know they exist.

Claude Code hooks let you run scripts at specific points in Claude's lifecycle — before it runs a command, after it edits a file, when a session ends. Right like, this is not a Claude trick or a prompt engineering thing, this is actual infrastructure. You're wiring event handlers to Claude's actions the same way you'd wire them to any other system. That's what makes it a professional environment and not just a really fast tab-completion.

I'm a Lead Engineer. I work on distributed systems that process $5.2 trillion in assets for over a thousand advisory firms. When I started using Claude Code seriously for side project work, the first thing I did was build the safety layer I'd build for any critical system — guard against destructive operations, enforce quality checks, automate the handoff so context doesn't disappear. These hooks are that.

The 4 hooks in this pack are running in my production environment right now. This is not a demonstration. This is what I actually use.

The 4 hooks

What each one does, why it matters, what breaks without it.

Each hook is a single file with a clear job. There's no framework, no dependencies — just a script that runs at the right moment. The installation guide tells you exactly where each one goes. Install time is about 15 minutes total if you read the guide first and don't try to figure it out from the code alone.

Anti-Deletion Guard

pre-tool-use.hook.sh

Intercepts bash commands before they run and blocks anything destructive — rm -rf, git reset --hard, drop table, and a configurable list you add to. The command doesn't run. Claude gets a message explaining why. You get to explicitly allow it if you actually meant it.

This isn't about Claude being reckless — it's about the fact that at 11pm after 3 hours of debugging, you will at some point tell Claude to "clean everything up" and it will interpret that more literally than you intended. The guard runs before that interpretation becomes a file you can't get back.

Without it: Claude can and will execute destructive operations when instructed — including ones you didn't mean to instruct. If you're not reviewing every bash command Claude runs, you're relying on it not making that mistake.

Quality Check

post-file-edit.hook.sh

Scans every file Claude edits before you see the result. Looking for three things: hardcoded secrets (API keys, tokens, connection strings — real patterns, not just the word "secret"), leftover console.log statements that shouldn't go to production, and TODO comments that accumulate into technical debt nobody meant to ship. Flags them in the output so you decide before you commit.

This one is the "I should have had this" hook. The first time it catches a hardcoded token in a file Claude generated, you will understand immediately why it's in the pack.

Without it: These things go to commits. Sometimes to production. Sometimes to GitHub where they're public. This is not theoretical — it's a known pattern with AI-generated code and it's caught in post-mortems, not pre-commits.

Auto-Handoff

session-stop.hook.sh

Runs when a Claude session ends. Writes a timestamped handoff note to docs/handoff.md — what was worked on, what was changed, what's still open, any blockers. Tomorrow-you opens that file and picks up in 30 seconds. You stop rebuilding context from git blame and trying to remember what you were thinking.

This is the one that changed how I work the most. I build in the evenings when I can, right like sometimes it's 45 minutes, sometimes it's two hours, always with three kids and a full-time job competing for the same brain. The handoff note means I don't lose the thread just because I had to stop.

Without it: Every session restart costs you 15-20 minutes of context recovery. At 3 sessions a week that's an hour you're spending re-orienting instead of building. Multiply that over a month and you'll understand why the project keeps stalling.

Sync Guard

post-file-edit.sync.hook.sh

Monitors specific shared files — design tokens, brand kits, API schemas, anything that multiple projects depend on. When one of those files changes, it drops a flag and alerts you that downstream projects need to sync. It doesn't do the sync for you — that's on purpose, you should control that. It just makes sure you know.

This one is for people building more than one project that share infrastructure. If that's not you yet, you can configure it for whatever shared files matter in your setup — environment config, shared components, documentation that stays in sync. The guide has examples.

Without it: Design tokens change in project A. Project B silently runs on old values. You debug visual inconsistencies for an hour and trace it back to a token that changed two weeks ago. This is the kind of thing that's obvious in retrospect and invisible in the moment.

Full settings.json configuration template.

The hooks don't do anything if they're not wired up. The included settings.json template shows you exactly how to register each hook, what permissions each one needs, and how to configure the paths and patterns for your project structure. The installation guide walks through every field. There's nothing to figure out, just fill in your paths and it runs.

.claude/settings.json (structure preview)
{
  "hooks": {

    // Runs before every bash tool call
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [{ "type": "command",
          "command": "bash .claude/hooks/pre-tool-use.hook.sh" }]
      }
    ],

    // Runs after every file edit
    "PostToolUse": [ ... ],

    // Runs on session end
    "Stop": [ ... ]

  },

  // Configurable patterns for Anti-Deletion Guard
  "deletionGuard": {
    "blocked": ["rm -rf", "git reset --hard", "DROP TABLE"],
    "custom": []  // add your own
  }
}
# Full template + path config in the download.

15-minute install. You don't need to understand the hooks to run them.

If you want to read the code you can — it's all annotated. But you don't have to. The installation guide is step-by-step and you don't need to modify anything to get all four hooks running. After that, you configure the patterns that match your project structure and you're done.

step 01
Create .claude/hooks/ directory in your project root
step 02
Copy the 4 hook files into .claude/hooks/
step 03
Add the provided settings.json to your .claude/ directory
step 04
Update the path and pattern config to match your project (guide has examples)
step 05
Open a Claude Code session and run the provided test sequence — each hook confirms it's active

I'm a Lead Engineer at Orion Advisor Solutions where my team's distributed trading systems process $5.2 trillion in assets for over a thousand financial advisory firms. I design systems where "it mostly works" is not a standard. I've been doing this for 8+ years — Java, C#, Node.js, AWS, the whole stack, event-driven architecture, the kinds of systems where latency and reliability are not optional requirements.

I started using Claude Code seriously for side project work and the first thing I noticed was that most people use it like an autocomplete that can write whole files. And it does that well. But the thing that made it actually trustworthy for production code — even side project production code — was the infrastructure layer. The hooks I built are the same thing I'd build for any critical process: guard the destructive operations, enforce the quality check, automate the handoff. I put these together in a pack because every developer using Claude Code should have them running. The setup takes 15 minutes. The alternative is finding out the hard way what happens without them.
