Shows which /effort level each message needs, the moment you send it, judged by TypeSafe's Jev, and switches on your OK. Based on 'Using Claude Code: Spending…
Shows which /effort level each message needs, the moment you send it, and switches on your OK. TypeSafe's Jev model reads your message and gives a one-line verdict against the level Claude is about to run on (⬆ needs high, ⬇ low is enough, ✓ medium fits). When the level looks wrong, in either direction, a dialog (ask_first) or a band above the prompt (1: switch, 2: keep) switches it for that message's turn. It never switches on its own.
Needs Claude Code 2.1.287 or later and a TypeSafe API key, entered when you enable the plugin and kept in secure storage.
Options: language (en / zh), quiet, ask_first, log_decisions.

hooks/register.tsx 815 lines1// spending-effort-with-jev as a mod: judge each typed message with Jev, then,
2// before the model request that would run it, compare with the live effort
3// and let the person switch from the UI. The switch rewrites the effort of
4// this session's main-loop requests; the setting under the input box is
5// untouched, and changing it there takes back control. Around that: a ledger
6// of what each level cost, subagents sized by their own task, a mid-turn
7// downgrade hint, a spec interview before long fuzzy runs, and thresholds
8// tuned to the person's own answers.
