rpg-companion-app-systems

Create or modify RPG Companion App resource instances (.json or .rpg) under systems/<system>/resource_instances using stats.rpgs schemas. Use when asked to edit, bulk update, or generate instances for 5e or 5e2024 (including imports from external JSON). Always run scripts/validate_resource_instances.py and then scripts/format_resource_instances.py after changes.

Import or assess a 5etools book or source for RPG Companion systems, including cloning 5etools-src, reading a book JSON or source id, determining dependency-aware resource creation order, updating or creating importer logic, generating resource instances, auditing mechanics and counters, and validating the result. Use when Codex is asked to onboard a new 5etools book, source, class/species/feat/background batch, or create a reusable import pipeline for RPG Companion.

Edit RPG Companion App system files under systems/<system>/system (such as .rpgs and .rpg.json), including stats formulas, mechanics, views, resources wiring, and combat behavior. Use when asked to adapt rules behavior in an existing system, add/update RPG Script formulas, or troubleshoot system-file logic. Prefer MCP dev-tool validation when available, with local fallback checks.
