# Artifact Format

> This skill provides strategic spec artifact format knowledge. It activates automatically whenever working with -spec.md files, .ido4shape/ workspace files, or when the conversation involves writing capability definitions, group definitions, metadata fields (priority, risk, dependson), dependency references, success conditions, or structured markdown specifications. Also triggers when the user mentions "artifact format", "spec format", "strategic spec", "heading pattern", "metadata", "prefix", "dependson", "success conditions", "group prefix", " Group:", " PREFIX-", or discusses how to format specification output.
