The Agent Skills Directory

[COMMAND_EXECUTION]: The skill guides users to run CLI commands such as npx eventcatalog fitness check to evaluate architectural rules in local development and CI environments.
[DYNAMIC_EXECUTION]: The skill assists in authoring and executing custom TypeScript logic (*.fitness.ts files) that is processed at runtime by the EventCatalog CLI to validate architectural constraints.
[EXTERNAL_DOWNLOADS]: Instructions and examples involve the use of official Node.js packages including @eventcatalog/core, @eventcatalog/cli, and @eventcatalog/fitness from the vendor's official distribution channels.
[INDIRECT_PROMPT_INJECTION]: The fitness functions process architectural metadata from the catalog, representing a surface where modified catalog data could influence the automated checks. 1. Ingestion points: Catalog resource data (Markdown and YAML frontmatter) is read via the catalog SDK methods defined in references/api.md. 2. Boundary markers: No specific delimiters or safety instructions are defined for the ingested catalog content. 3. Capability inventory: The system executes TypeScript logic with project-level access to perform analysis, as described in the 'Trust' section of SKILL.md. 4. Sanitization: The skill provides examples of parsing catalog data using standard methods like JSON.parse but relies on the integrity of the local catalog files.
