Use when writing, modifying, debugging, reviewing, or refactoring TypeScript or JavaScript code in an existing repository. Enforces explicit assumptions, simple solutions, surgical diffs, test-backed changes, and strong TypeScript hygiene. Do not use for greenfield brainstorming where broad exploration is more important than conservative implementation.
Model and change AetherTarot's reading runtime state for `POST /api/reading`. Use when Codex is designing or modifying canonical reading flow, question classification handoff, spread/card hydration, draft-to-structured output mapping, LangGraph node boundaries, or `session_capsule` insertion points in the reading pipeline. Do not use for tarot knowledge ingest, pure UI rendering tweaks, or generic LangGraph tutorials. This skill only serves reading-state and orchestration tasks in `apps/web/src/server/reading/`, `packages/shared-types/`, and the matching docs.
Handle AetherTarot safety escalation, output restriction, and reality-based referral for high-risk readings. Use when Codex is changing crisis handling, self-harm or violence responses, health or legal or financial boundary logic, manipulation or abuse-related guidance, `safety_note` generation, or future human-review interruption paths. Do not use for routine tarot tone tuning, ordinary reading synthesis work, or generic human-in-the-loop tutorials. This skill only serves high-risk output control in `apps/web/src/server/reading/safety.ts`, the reading contract, safety docs, and the structured output schema.
Design and change AetherTarot's session capsule, history summary, and long-term memory boundaries. Use when Codex is implementing or revising `session_capsule`, history replay semantics, memory merge rules, thread or session persistence, or user-profile retention for readings. Do not use for generic database work, unrelated localStorage cleanup, or broad LangGraph persistence tutorials. This skill only serves memory and persistence tasks tied to `docs/30-agent/context-strategy.md`, `apps/web/src/context/ReadingContext.tsx`, `apps/web/src/server/reading/`, and the shared reading schema.
Compile unstructured tarot source material from `knowledge/raw/` into governed Markdown pages under `knowledge/wiki/` that conform to `knowledge/AGENTS.md`. Use when Codex needs to ingest raw books or notes, create or revise card/concept/spread pages, register new source IDs, merge multi-source interpretations, or synchronize `knowledge/index.md` and `knowledge/log.md` after wiki ingest or lint work.
