What problem does it solve? Controlling exactly which directories, files, file types, and URLs a Fux search index covers requires editing committed lists in .fux/ correctly, and mistakes like stale exclusions or wrong attributes silently leave documents unindexed. ## Core Features & Use Cases - Corpus Editing: Add or remove directories, files, file-type patterns, and URLs with fux add and fux remove, including archived, keep, ttl, meta, and update attributes. - Re-ingestion Control: Run fux ingest in its correct form — --refetch-all, --no-fetch, --check, --failed — since fux update was removed in 3.0. - Diagnosing Missing Files: Answer "why isn't file X indexed" using fux ingest --list-skipped and the skip-reason table covering type allowlists, ! exclusions, and .fuxignore lines. - Use Case: A teammate asks you to index the docs/runbooks folder and a Confluence page, then refresh stale URLs; this Skill gives the exact commands and warns that a bare fux ingest hits the network. ## Quick Start Ask the assistant to index a folder or URL in the Fux corpus, for example by saying "add docs/runbooks to the fux index and re-ingest".
