Use when running isolated COC Keeper simulated-player tests, evaluator reviews, battle reports, evaluation reports, and regression checks in Codex.

Import and index authored Call of Cthulhu scenarios for COC mode. Use for rulebook scenarios, external module PDFs, scenario skeletons, source maps, Keeper-only separation, and on-demand PDF lookup.

Parse TRPG rulebook PDFs (especially 2-column layouts like Call of Cthulhu Keeper Rulebook) into structured data using pymupdf4llm. Use when extracting rules data from a PDF rulebook, verifying data against the source PDF, or checking parse quality. Handles the 2-column reading-order problem with pymupdf4llm (0.4s/page, correct column order, Markdown table output). Also provides bbox overlay visualization and quality scoring. Use when the user says "解析 PDF / 核对规则书 / 双栏排版 / extract from rulebook".

Thin Cursor entry for COC Keeper. Use after the user explicitly activates COC mode (e.g. "Activate COC mode", "进入 COC 模式"), or when a Cursor try/demo prompt asks to use the plugin in a concrete/useful way or show why it is valuable. Routes to coc-main onboarding — not a rules-engine demo. Canonical skills live under plugins/coc-keeper/skills/. Portrait generation is Codex-only; skip imagegen on Cursor.

Activate and orchestrate COC mode. Use for activate/enter/continue/pause/save/exit Call of Cthulhu play, and for host try/demo prompts that ask to use COC Keeper in a concrete/useful way or show why the plugin is valuable. Prefer this over rules-engine demos for first contact.

Resolve structured Call of Cthulhu rules for skill checks, success levels, half/fifth values, bonus or penalty dice, damage bonus, build, sanity thresholds, and rules parameter inspection. Do not use for host try/demo or “show why the plugin is valuable” prompts — those go to coc-main onboarding instead.

Resolve Call of Cthulhu chase scenes during COC mode using the full Chapter 7 Parts 1-5 system. Use for establishing pursuits (CON/Drive Auto speed rolls), Cut to the Chase positioning, location chains with hazards and barriers, movement-action economy, Pedal to the Metal, passenger assists, firing while moving, Choosing a Route, Sudden Hazards, same-location melee delegated to CombatSession, vehicle Drive Auto conflict, and structured chase state persistence via ChaseSession and save/chase.json.

Resolve Call of Cthulhu combat during COC mode using the full Chapter 6 system. Use for DEX initiative (with readied-firearm +50 and casting overrides), declaration of intent, multi-round opposed resolution (fight back vs dodge, distinct tie rules), the eight combat mechanisms (firearms cannot be dodged, Dive for Cover, Cover, Outnumbered, Point-Blank, Range→difficulty, Firearms DEX+50, flee), damage with armor/Flesh Ward, conditions (major wound/dying/prone/grappled/surprised), and structured combat state persistence via CombatSession and save/combat.json.

Run immersive Call of Cthulhu play after COC mode is active. Use for scene narration, NPC portrayal, player action handling, clue reveal, pacing, subsystem transitions, and campaign memory updates.

Provide spoiler-aware Mythos references for COC mode. Use for monsters, deities, spells, tomes, artifacts, combat stats, source pages, and Keeper-only lookup during scenario preparation or play.

Internal COC Keeper narrative orchestration layer. Use only after COC mode is active, before coc-keeper-play renders the next player-visible response, to choose scene direction, pacing, clue delivery, NPC moves, pressure clocks, and memory use. This skill does not output final narration to the player.

Resolve Call of Cthulhu sanity events during COC mode. Use for SAN rolls, sanity loss, temporary insanity, indefinite insanity, bouts of madness, delusions, reality checks, phobias, manias, and recovery notes.

Create and maintain reusable Call of Cthulhu investigators. Use for full guided investigator creation, quick generation, derived values, age modifiers, validation, development, and cross-campaign character history.

Manage project-local COC JSON state. Use for creating, reading, validating, snapshotting, or explaining .coc workspaces, campaigns, reusable investigators, logs, memory, indexes, and playtest sandboxes.

Handle out-of-character and system-level questions during COC mode. Use when the player asks rules questions, requests parameters, challenges a ruling, pauses narration, or asks about the COC system itself.
