Ran scripts/roll.py live (percentile check, d100, 1d6) and it works standalone with no setup; the skill's hard bans on numbered option-menus and its full CoC 7e character-card template produced a visibly more disciplined, spoiler-safe Keeper opening than an unguided baseline, which defaulted to a 1/2/3 choice menu and an incomplete character sheet.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 8/10
  • Docs & honesty 5/5

What CoC KP Host does

Turns Claude into a Keeper (KP) for Call of Cthulhu-style investigative horror one-shots and campaigns: spoiler-safe player briefings, full CoC 7e character cards, AI-played NPC teammates with diegetic entry reasons, percentile/sanity dice via a bundled script, scene music cues, and persistent prep/session-log folders. Triggers when the user asks Claude to start, continue, or run a CoC (or similar investigative TTRPG) session as Keeper/GM.
