Adds a new domain folder with a hub index and wires it into `_MANIFEST.md` -- for a new topic area, or splitting an existing domain into its own folder.
Moves a file from active (Tier 2) to archived (Tier 3) so Memex stops loading it automatically -- for a wrapped project, a stale reference, or a superseded file. The file stays on disk; only its manifest tier and hub status change.
Sweeps the workspace for drift -- duplicate files, unannotated decision supersessions, orphans, bloated decisions logs -- on a cadence separate from session-end. Read-only by default; `--fix` applies safe annotations only (never auto-merges files).
Trigger when the user's question spans multiple Memex workspaces and they don't know which one holds the answer, or they ask "have I written about X anywhere?". Not for questions the current workspace can answer -- use `/memex:search` instead. Reads only manifests and closets, never inside individual files.
Quick-capture an idea to the scratch inbox. Use when the user explicitly asks to capture: "capture this", "add to ideas", "don't let me forget", "log this idea", `/memex:idea`. Not for every "we should eventually..." aside -- most asides aren't capture-intent. Not for decisions (decisions.md) or state claims (closets `claims:` field).
Sets up Memex in the current workspace. Detects state -- fresh repo, existing repo with loose markdown, a foreign manifest, or an outdated version marker -- and runs the right combination of scaffold, scan-and-organize, migrate, or health-check.
Registers this Memex workspace in the global source registry so it's searchable from your other workspaces via `/memex:cross-search`.
Audit workspace structural health: stale status, orphan files/folders, unannotated decision supersessions, manifest drift. Read-only; `--fix` applies safe annotations. Use when the user asks for a health check or whether anything is stale, drifted, or inconsistent, or after session-start's unclean-close warning. Don't fire on vague unease or as a routine session step -- session-start/session-end handle hygiene. Wikilink targets: `/memex:wikilinks` (lint doesn't re-scan links).
