cross-search

name	cross-search
description	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.

Memex - Cross-Workspace Search

Wikilink rule: When referencing any file in markdown, always use [[filename]] wikilink format.

Grep across every searchable workspace in ~/.memex/sources.md, grouped by source. Reads only _MANIFEST.md, every _CLOSETS.md, and every _CLOSETS-archive.md. Fast and deterministic.

Registry conventions, script-path resolution, and privacy semantics: see references/registry.md. CLI surface: ${CLAUDE_SKILL_DIR}/scripts/sources.py.

Step 1: Query

Use $ARGUMENTS as the query. If empty, ask: "What do you want to search for across linked workspaces?"

Step 2: Confirm sources exist

python3 "${CLAUDE_SKILL_DIR}/scripts/sources.py" list. If none searchable, tell the user: "No linked workspaces yet. Run /memex:link-workspace from a workspace to register it."

Step 3: Search

python3 "${CLAUDE_SKILL_DIR}/scripts/sources.py" search "<query>"

The script greps each searchable source's _MANIFEST.md, _CLOSETS.md, and _CLOSETS-archive.md for matches. Results are grouped by source.

Step 4: Format output

If results found:

1. Show grouped raw results (file path, line, match).
2. Per source with hits, suggest: "To dive in, switch to that workspace (cd to its path) and start a session."
3. If a hub by the same name appears across multiple sources, call that out.

If no results:

No matches for "<query>" across <N> linked sources.

Either:
- The subject hasn't been wikilinked into any manifest or closets file.
  /memex:resummarize in the relevant workspace would surface it.
- The subject lives only inside files (not in manifests/closets). Open
  the workspace directly to search inside files.

Gotchas

• Index-only search. Manifests and closets. Never inside content files. Closets are the index, content is the body. If a subject isn't wikilinked into a closet, it's invisible here. Closets format spec: memex/skills/session-end/references/closets-format.md.
• searchable: false is total. A source opted out is skipped silently. No partial visibility.
• Case-insensitive substring. Regex chars in the query are escaped automatically; you can't use regex.
• Missing path = silent skip per source. If a workspace was moved after linking, cross-search prints (path missing: ...) for that source and continues. Fix with unlink + re-link.
