/cct:jev — optional Jev spawn routing (v4.4.0, Phase 1a)

Run exactly one command, using the word the user typed after /cct:jev (no word means status), and relay its output verbatim:

python3 "${CLAUDE_SKILL_DIR}/jev_ctl.py" status

(on, off or report in place of status.) Never edit .claude/settings.local.json or <git common dir>/jev/config.json yourself: jev_ctl.py writes the config, and on/off also clear a v4 registration left in the settings file (off restores that file byte for byte when nobody edited it since the v4 /jev on).

What it does

• On (per clone): writes {"model": "jev-1.13.0", "threshold": 0.65, "route": true, "legs": false} to <git common dir>/jev/config.json. Nothing else is written: the cct plugin registers the router (hooks/jev-route.sh, PreToolUse Agent) and the session notice (hooks/jev-notice.sh) itself, and both act only while that file says "route": true. Every checkout of the clone, worktrees included, is covered by the one switch. A v4 /jev on left an entry in this checkout's .claude/settings.local.json; on and off remove it (until then the plugin steps aside for it, so routing never runs twice).
• Per spawn that passes no model: TypeSafe's Jev picks a model in ~0.3 s. It applies only at confidence ≥ 0.65 (the threshold in the config; a one-week trial value), and may pick any model on haiku < sonnet < opus < fable, never below sonnet for review/architect types, whose effort is also never lowered below the agent file's (with no agent effort they keep the session's). A spawn with no model of its own always leaves with one: Jev's choice, or the project floor when Jev is unsure, slow (2 s), unreachable or keyless. Jev's effort is applied at the same threshold when it differs from the agent file's effort: (an agent file without one counts as different); an effort you pass on the spawn is never changed. A typed agent whose model stays the same gets the effort only, never a pinned model.
• Off: the switch goes off first, so hooks/model-floor.sh floors again at once. Then any v4 registration and notice in .claude/settings.local.json are removed. Events stay for /cct:jev report.

/cct:jev report stays per clone. For the cross-machine trial tally over every clone under a root, run python3 <toolkit>/scripts/jev-tally.py [--since DATE] [ROOT...] (default root ~/git; the PC passes G:/git). It is read-only and prints counts only.

While on: omit model (user ruling U-1, 2026-10-02)

"Jev decides, I don't." While Jev routing is on in this repo, do NOT pass model on Agent spawns. Jev picks one per launch. This is the exception to the user-level rule "every Agent spawn names its model". After /cct:jev off, name model again. A model you do pass is never changed, so passing one opts that spawn out of routing.

AGENT_TEAM.md's "Typed agents own their model; a type without one (general-purpose, built-ins) gets the project default via hooks/model-floor.sh unless you pass one" is overridden for spawns Jev routes, within the bounds above: Jev may move a typed agent to any model and set its effort.

What leaves the machine

Only for a spawn Jev routes: the agent type, description and prompt, with secrets, emails, your username and home paths masked, trimmed to 4,000 characters. A spawn whose text still holds a secret-shaped token is not sent at all. The key (TYPESAFE_API_KEY, else HKCU\Environment) goes in a header only and is never printed or logged. <git common dir>/jev/events/ holds decisions and confidences, never the prompt or the key.
