What problem does it solve? Retiring a study by hand leaves broken catalog entries, stale proposal-registry rows, and dead links across the site. This Skill runs the repository's removal script so the study directory, catalog JSON, README rows, references, and pipeline metadata are all updated together. ## Core Features & Use Cases - Complete study removal: Deletes the full Studies/<Slug>/ or Applications/<Slug>/ directory and removes its catalog entry from JSON, README, and the rebuilt index. - Metadata cleanup: Clears the slug from proposal-registry.json, presentation-pipeline.json, and companion-pipeline.json, including metadata-only cleanup when the directory was already deleted. - Reference maintenance: For published studies, removes the References README row, MANIFEST block, and by-tag citations while preserving citations to other studies. - Use Case: An Ongoing placeholder study is abandoned; run the script with --dry-run to preview, then --yes to delete the directory, catalog row, and registry entry in one step. ## Quick Start Ask the assistant to remove the study with slug 'The-Ontology-of-Coexistence' using the remove-study script, starting with a dry run to preview the changes.
