What problem does it solve? Teams keeping plans, findings, and analyses as Markdown files under .context/ lose track of what exists as the folder grows, and pre-commit hooks fail when files lack required YAML frontmatter. This Skill rebuilds .context/index.yaml from the frontmatter of every .context//*.md file and reports files with missing or malformed metadata. ## Core Features & Use Cases - Index regeneration: Scans all .context//*.md files, parses title/type/status/date/related frontmatter, and writes a grouped, sorted index.yaml. - Frontmatter validation: check-context-frontmatter.sh and validate-context-frontmatter.sh detect missing or schema-invalid frontmatter before commits. - Staleness and naming checks: Advisory scripts flag active plans older than a threshold and enforce date-first filename conventions. - Use Case: After adding two new finding files, run the regenerate script so agents querying "what plans exist?" see a complete, current index with zero warnings. ## Quick Start Ask the agent to regenerate the context index and fix any files reported as missing frontmatter.
