loopkeeper

See and steer your subagents: cards with cost, tokens, context and progress, tree and team views, spawn caps, permission waits, idle alerts and a Stop button.

Know when Claude needs you or finished something long: a desktop notification, a sound, a toast, a band and an /lk-attention inbox. Linux with GNOME.

Don't lose a session to the context limit: watches context fill, writes a handoff into .claude/brain/ before the limit, then clears and resumes from it.

PR and CI state for the current branch above the prompt, toasts on transitions, and a note to Claude when a check fails. Works through your gh sign-in.

Stops credential-shaped strings and a private deny-list of words from being written into files or shell commands, by Claude or by any subagent.

A token budget for the session and each subagent that warns, refuses new subagents or stops tool calls, and a prompt-cache timer with an opt-in keep-warm.

One line above the prompt with the repo, branch and worktree, how dirty it is, and the account's usage windows and prompt cache, plus a /lk-where pane.

Keep Claude on a plan: a staged loop with approval gates, a plan-scoped file budget, protected paths, a ship gate, model routing, review loops and a decision log.
