Sleepz

Stop wasting time waiting for sleep to finish.
A Claude Code plugin that automatically adjusts sleep durations to account for permission dialog wait time and internal processing overhead.

The Problem

When Claude Code proposes sleep 60 && npm run build, you have to approve it first. If you take 15 seconds to hit "Allow", the sleep still runs for the full 60 seconds — meaning 75 seconds pass instead of the intended 60.

Claude Code also adds its own processing overhead (~1s) between deciding to run a command and actually executing it. These hidden delays add up.

Sleepz fixes this. It accounts for both delays and ensures the total wall-clock time matches what was originally intended.

Install

/plugin marketplace add rafet/claude-code-sleepz
/plugin install sleepz@claude-code-sleepz

That's it. No configuration needed — it works out of the box.

How It Works

A PreToolUse hook intercepts Bash commands containing sleep, records a timestamp, and replaces sleep with a lightweight wrapper. After you approve the command, the wrapper calculates how much time already elapsed and sleeps only the remaining duration.

sleep 60 && npm run build

       ▼                                   │
  Wrapper: 60 - 16 = 44s remaining  ──────┘
       │
       ▼
  sleep 44 && npm run build

The hook itself adds only ~15ms of overhead — negligible compared to the time it saves. Non-sleep commands are filtered out by a fast bash pre-check without spawning any extra processes.

What Gets Adjusted

Command	Behavior
sleep 60	Adjusted
sleep 60 && cmd	First sleep adjusted, rest of the command runs normally
sleep 0.5	Adjusted (fractional values supported)
sleep $VAR	Skipped — variables can't be parsed statically
sleep 60s / sleep 1m	Skipped — suffixed durations not supported
bash -c "sleep 60"	Skipped — nested shells are left untouched
sleep 10 && sleep 20	Only the first sleep is adjusted
Hook or script error	Original command runs unmodified — never breaks your workflow

Time Saved

Sleepz silently tracks how much time it saves you in ~/.claude/sleepz-stats. To see your stats:

~/.claude/sleepz --stats
# sleepz stats: 47 commands optimized, 3m 42s saved

The stats file is append-only and parallel-safe — no data is ever lost, even with multiple Claude sessions running simultaneously.

Configuration

Disable Sleepz temporarily with an environment variable:

export DISABLE_CC_SLEEPZ=1

Requirements

• Bash
• Claude Code with plugin support
