Best Claude Code hooks

Explanations as visual pages in a pane beside the chat: diagrams drawn in place, the full page one click away. No model calls.

Tells you when a newer version of an installed claude-pro-kit mod is out, and /kit-update installs it. One small download per session, no tokens spent.

Claude Code mod that skips Claude re-reading a file it already read in the same conversation when the file's size and modification time have not changed, while allowing deliberate retries, different ranges, subagents, and post-/compact or /clear reads through.

Make the $20 Claude Pro plan last longer in Claude Code.

A Claude Code plugin that trims long Bash/PowerShell output before Claude reads it, keeping the head, tail and error lines, and saving the full output to a file Claude can open without a permission prompt.

/receipt opens a pane with the exact tokens every turn of the session spent (uncached, cached, output, subagents) and the costliest turns. No tokens spent.

A Claude Code mod from the claude-pro-kit marketplace that shows a countdown until the prompt cache expires in the status line, and once it has expired, reports exactly how many tokens the next message will re-send uncached.

Stops Claude reading a file over 1,000 lines whole and gives it an outline tool (definitions with line numbers) so it reads only the range it needs. A retry still reads it whole.

Asks before a single turn uses more than +5 session points or 500,000 uncached input tokens, and stops it cleanly if you say so. Checks between requests, never mid-command.

A Claude Code mod that asks before Claude edits a file another chat on this machine changed in the last 30 minutes. Each chat records its own edits in a per-session ledger under ~/.claude/collision-guard/, so two chats never write the same file. No model calls, no network; zero tokens unless you press Cancel.

Desktop heads-up display for the Pro plan: exact 5h/7d usage gauges, context gauge, turn receipts, usage in the spinner and compact tool cards. No estimates, no tokens spent.

Moves tools you have not used lately behind ToolSearch, so their descriptions stop riding along on every request; core tools and anything you used in your last five sessions stay loaded.
