start

start is a command for Claude Code from aniketkarne/ClaudeNightsWatch. It costs 12 tokens per session (499 once invoked), scanned A, original, MIT.

A command that starts the Claude Nights Watch background service, which monitors Claude usage windows and runs tasks from a task.md file.

In plain words
What is it for?
Use it to start monitoring immediately or schedule it for a specific time, while recording activity in a log file.
Why use it?
It lets tasks continue to be monitored and executed around Claude's five-hour usage limit without manually starting each run.

Command for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the ClaudeNightsWatch plugin — 6 commands, 3 hooks, 1 MCP server shipped together

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

start scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Start Nights Watch Daemon

Starts the Claude Nights Watch daemon to monitor your Claude usage windows and execute tasks from task.md automatically.

Usage

/nights-watch start [OPTIONS]

Options

  • --at TIME - Schedule daemon to start monitoring at a specific time
    • Format: HH:MM (today) or YYYY-MM-DD HH:MM (specific date/time)
    • Daemon will wait until scheduled time before beginning task execution

What It Does

  1. Checks for required files (task.md in current directory)
  2. Starts background daemon process
  3. Begins monitoring Claude usage windows
  4. Executes tasks when approaching the 5-hour limit
  5. Logs all activity to logs/claude-nights-watch-daemon.log

Prerequisites

  • task.md file must exist in current directory (create one if not present)
  • rules.md file is recommended for safety constraints (optional)
  • Claude CLI must be installed and configured

Examples

Start immediately:

/nights-watch start

Start at 9 AM today:

/nights-watch start --at "09:00"

Start at specific date and time:

/nights-watch start --at "2025-10-12 14:30"

Implementation

${CLAUDE_PLUGIN_ROOT}/claude-nights-watch-manager.sh start "$@"

Safety Notice

⚠️ The daemon uses --dangerously-skip-permissions for autonomous execution. Always:

  • Test tasks manually first
  • Use comprehensive rules.md for safety constraints
  • Monitor logs regularly
  • Start with simple, non-destructive tasks

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
