Agent Bedtime — Development skill for Claude Code

agent-bedtime

Claude Code hook that reminds you to go to bed. Every message you send past bedtime, Claude gets told to remind you to wrap up and go to sleep.


How it works

A `UserPromptSubmit` hook that fires on every message you send. If the current time is past bedtime, it injects a bedtime reminder into Claude's context via stdout (exit 0). Claude sees it and reminds you naturally.

Each prompt during bedtime is logged as a violation to `~/.agent-bedtime/violations`. As violations accumulate, the hook instructs Claude to get progressively more annoying:

Violations	Tone
1	Gentle reminder
2-3	Firm, mildly disappointed
4-5	Persistent and direct, keeps responses short, won't engage with new work
6+	Maximally stubborn, extremely brief, enthusiastically sells you on how great sleep is

Violations are automatically cleared once wakeup time passes the next day. On clearing, a summary row is appended to `~/.agent-bedtime/history.csv`:

date,violations,first_violation,last_violation
2026-02-21,14,2026-02-21 23:57:01,2026-02-22 00:41:30

Install

Add to `~/.claude/settings.json`:

{
  "hooks": {
    "UserPromptSubmit": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "~/code/tools/agent-bedtime/bedtime-hook"
          }
        ]
      }
    ]
  }
}

Config

Create `~/.config/agent-bedtime` (required):

BEDTIME=23:00
WAKEUP=06:00

Optionally, add a `CONTEXT` line with extra motivation. This gets included in the hook message, giving Claude more to work with:

CONTEXT="The user has a 7am meeting tomorrow. They're working on a sleep consistency goal this month."

Changes take effect immediately — the file is sourced on every hook invocation, so no restart needed.
