Prompt

Jev ranks every file in the repo against each prompt in ~0.5 s and hands Claude the likely relevant ones (System-1 file triage).

Catches tests being weakened to make them pass: every test-file edit is judged by Jev in a few hundred ms against what you asked for.

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

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.

/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.

Ask before guessing: when a prompt looks ambiguous, Claude asks up to three clarifying questions first. Off until /clarify on.

Inline #tokens that attach live context to a prompt: #diff, #staged, #log:20, #tree, #todo, #errors, #file:path:10-40, #url:https://...

Set the effort for one prompt with a caret prefix: ^max, ^xhigh, ^high, ^med, ^low (^^ = max, ^ = high).

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

One-tap follow-ups: after each answer, three short next prompts above the prompt, on keys 1-3.

Standing context you control: pin notes and files once, and every prompt you send carries them.

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.

Rough idea in, precise prompt out: /polish or a trailing ?? rewrites your prompt into the input box for you to edit and send.

Park a half-written prompt, ask something else, and pop it back into the box later.

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

"Look, don't touch": /readonly on blocks edits and every command that is not provably read-only, and tells Claude to investigate and explain instead.

Keeps credentials out of your code, your shell commands and Claude's context: blocks hard-coded secrets in edits, asks before commands with literal keys, redacts secrets from tool results and flags them in prompts.

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.

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.

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

A one-line TL;DR under long answers, written by haiku.
