Coding Tips: 3 Claude Code Mods (take them)

From the video "3 Claude Code Mods I Built in 5 Minutes (Take Them)".

ModWhat it does
spinner-quipsReplaces the spinner word with a joke ("Blaming the intern", "Googling the error"…) and counts tool calls
safety-netBlocks rm -rf, git push --force, git reset --hard and DROP TABLE, and shows a warning
session-hudA live HUD above the prompt: time, tool calls, files edited, context bar, cost, and a mood 😎 😅 🥵

Needs Claude Code v2.1.287 or newer (Desktop app v2.1.286+).

Install (inside Claude Code)

/plugin marketplace add ivtrade777/coding-tips-mods
/plugin install spinner-quips@coding-tips-mods
/plugin install safety-net@coding-tips-mods
/plugin install session-hud@coding-tips-mods
/reload-plugins

Install only the ones you want.

Or try all three for one session, without installing

git clone https://github.com/ivtrade777/coding-tips-mods.git
claude --plugin-dir ./coding-tips-mods

Make them yours

Each mod is one short file: <mod>/hooks/register.ts (or .tsx). Change the jokes in spinner-quips, add your own dangerous commands to safety-net, or new stats to session-hud, then run /reload-plugins.

Before you install any mod

Mods are not sandboxed: they run with your permissions. Read the code (each mod is one short file in hooks/) and check what it does:

claude plugin validate ./session-hud

Tests: claude plugin test ./safety-net
