doom
Doom above the Claude Code prompt, for the minutes Claude spends working: a corridor shooter: imps, a shotgun, and the floor below. The game pauses and its status line says so when Claude finishes the turn, so you never miss a reply. Playing costs no tokens: the mod answers every key and click itself.

View all mod skills →Prompt Cache Control
Prompt-cache meter above the Claude Code prompt: how many tokens each request read from, wrote to and sent past the cache, a live countdown to the cache's expiry, and what to do about it (keep going, compact or clear). The TTL follows Claude Code's own rules for your account (1 hour on a Claude subscription, 5 minutes on an API key, cloud provider or usage credits, plus the TTL variables and setting) and corrects itself from request timing. When Claude Code will compact an idle conversation by itself, it counts down to that too. cache opens a per-turn table.
Jev Model Router
Picks the model and the reasoning effort for each task with TypeSafe's Jev, a System One decision model reached either through TypeSafe's own API or the Vercel AI Gateway. Routes subagent models at agent.spawn and the main loop's effort and model at turn.step, in both directions, falling back to the engine's built-in classifier when no key is set.
Jev Skill Suggestion
Keeps the skill listing out of the context window and lets TypeSafe's Jev, a System One decision model, pick at most one skill per prompt from the skills' descriptions, the way TypeSafe's skill-suggestion cookbook does: one request ranks every skill and asks whether the prompt needs a skill at all, a second re-reads the top three with their SKILL.md and can reject them all. The winner's SKILL.md is attached to the prompt, so the skills can be hidden from the model altogether ( jev-skill-suggestion:setup makes them user-invocable-only and context counts them at 0). Falls back to the engine's built-in classifier when no key is set.
