Claude Watcher — Development skill for Claude Code

Claude Watcher

A Claude Code mod that shows what Claude is doing in one place: the current turn, the plan, subagents, your other sessions and the session's health. It works in the terminal, the Desktop app and VS Code.

• Spinner suffix: npm test · 2:14 · ~1:46 left · 3/5 tasks
• Dashboard pane (/watch) with six tabs: Turn, Plan, Agents, Sessions, Health and Config
• Attention band above the prompt when Claude needs you, plus an optional toast and desktop notification
• Visuals: Svg bars, Gantt, sparkline and donut on Desktop and VS Code; Raster bars, swimlanes and a heat strip in the terminal; a text fallback everywhere
• Time-left estimates learned from your own command history: ~ with 3 or more samples, ? with fewer, up to when only a timeout bounds the call

Claude Watcher only observes. Every hook passes the event on unchanged, and it never blocks or denies anything.


Install

Requires Claude Code 2.1.304 or later.

At the prompt of a terminal session:

/plugin install watcher --marketplace 31mahadi/claude-watcher

From a shell:

claude plugin install watcher --marketplace 31mahadi/claude-watcher

To run it from a checkout:

claude --plugin-dir ./claude-watcher

Updating

Watcher checks GitHub for a new release once a day. When one is out, it shows a toast once with the version and the update commands. The check sends no data and stays quiet when you are offline.

Update by hand

At the prompt of a terminal session:

/plugin marketplace update claude-watcher
/plugin update watcher@claude-watcher

From a shell:

claude plugin marketplace update claude-watcher
claude plugin update watcher@claude-watcher

Restart Claude Code afterwards so the new version loads.

Update automatically

Auto-update is off by default for marketplaces outside Anthropic. To turn it on:

1. Run /plugin.
2. Open **Marke
