# Wt Cleanup Loop

> Polls for merged PRs and closes the herdr workspaces or tmux windows behind them, on a timer. Args: [tick] [duration], defaults 5m and 3h. Use when the user wants tabs cleaned up as PRs land rather than right now: \"watch and close tabs as PRs merge\", \"wt cleanup-loop\", \"keep sweeping finished worktrees for the next few hours\". Same skill on both multiplexers; there is no herdr-specific vari…

## Install

```sh

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# Watch For Merged PRs

```bash
wt cleanup-loop $ARGUMENTS
```

Run it in the background. It prints one line per tick, so the user sees
closures as they happen without the loop blocking you.

```text
wt cleanup-loop            # 5m tick, 3h duration
wt cleanup-loop 2m 1h
wt cleanup-loop 10m        # 10m tick, 3h duration
```

## Why this is a shell loop, not an agent loop

The check is `gh pr list` per open worktree. Pure lookup, no judgement. An
earlier version woke a background subagent every tick to run it, which cost
tokens on every sweep and added a failure mode (an agent mis-transcribing the
safety rules) to a task that has no ambiguity in it. The loop lives in
`wt-cleanup-loop`, which calls `wt clear --merged-only` and sleeps.

Two consequences worth passing on to the user:

- It only closes **merged** PRs. Closed-without-merge often means the work is
  still wanted, so it is left alone; `wt clear` without the flag sweeps those too.
- Nothing is deleted. Checkouts and branches stay in `~/_wt` and git; `wt open
  ` brings any of them back. Deleting is `wt-remove`.

Do not build your own polling wrapper. That re-adds the cost this design removed.
