Panes

Jev notices when a prompt starts an unrelated task and offers a fresh conversation for it, saving context and prompt cache.

Every failed Bash/PowerShell command gets an instant Jev diagnosis (15 failure classes) and a playbook in this project's terms, as a note Claude reads.

Huge Bash/PowerShell outputs cut to the lines that matter: Jev scores every 12-line chunk against your request, the full log is saved for Claude to open.

Compaction without amnesia: archives the full transcript before each compaction and tells the summarizer to keep paths, decisions, preferences, TODOs and working commands.

What Claude touched this session: reads, edits (+/− lines), searches per file, main vs subagent, with flags for blind edits and repeated reads.

Git at a glance and in reach: a branch/changes status line, a /git pane to diff, stage, revert and commit, and Conventional Commit messages written by haiku.

/handoff writes a structured handoff (goal, state, decisions, files, next steps, gotchas, how to verify) to .claude/handoffs/; /handoff load hands it to a later session.

Project memory across sessions: every few turns haiku writes what was done, decided and left open to .claude/journal.md, and new conversations start with the latest entries.

Whole-tree time travel: a git snapshot of every non-ignored file before each turn, with diff, restore and /undo, never touching HEAD, the index or the stash.

Switchable working styles (teach, terse, pair, review, tdd, explore, ship, or your own) applied to every prompt you send.

Starts every conversation oriented: one context block with the repo, branch, layout, stack and its build/test/lint/run commands, README summary and recent commits.

Every prompt you write, kept across sessions and projects: /history searches them and puts one back in the prompt box.

Text expansion in the prompt box: type ;plan and a space, get the full instruction.

Blocks catastrophic shell commands (rm -rf ~, curl | sh, force-push to main, DROP DATABASE, format C:) and asks before risky ones (git reset --hard, rm -rf, terraform apply), in Bash and PowerShell.

Notices the commands you keep approving by hand and offers a one-click standing allow rule (never for risky or interpreter-wide commands).

Commit messages in your repository's own style (learned from its last 30 subjects) and pull request descriptions from the branch, drafted by haiku; nothing is committed or pushed without a press.

Opt-in: questions about the codebase (where is, what does, how does, which file, find) go to a read-only haiku scout subagent first; its answer comes with Ask Claude anyway and Good enough, and the tokens saved.

During long turns, haiku writes one line above the prompt every ~30 s on what Claude is doing and what comes next, from a compact log of its tool calls; a one-line recap toast after turns over two minutes.

A side conversation with haiku or sonnet in a pane, kept out of Claude's context: attach Claude's last answer, the diff, the plan or a file on demand, then send the answer or a summary to the prompt box.

Opt-in: after a turn that adds or changes functions, sonnet (or haiku) drafts focused unit tests in the background, in the repo's framework and style; Review, Add & run (only that file), or Dismiss; never writes without a press; daily budget cap.

Prompt-cache hit rate, a live warm/cold countdown, cache-bust alerts with likely causes, savings, and optional keep-warm pings.

Context-window gauge: a fill bar in the status line, toasts as it fills, a /ctx breakdown pane with Compact now, and optional auto-compaction between turns.

Spend tracking across sessions: session and today's cost in the status line, daily and weekly budgets with toasts and an optional hard stop, and a /spend pane.

Subscription rate limits at a glance: each window and its reset in the status line, toasts at 75% and 90% and when your pace beats the reset, and a /limits pane.
