Obsidian RAG Bridge

Compose Obsidian's graph with semantic search. The pattern: narrow to candidate notes via the graph/tags, then rerank semantically with rag.

1. Get candidate notes

Preferred — official obsidian CLI (requires Obsidian running; see obsidian help and https://help.obsidian.md/cli):

obsidian backlinks file="Project X"      # notes linking to a note
obsidian search query="retry policy"     # full-text candidates
obsidian tags                            # explore tags

Extract note paths from the output to feed step 2.

Fallback — rg/fd (Obsidian not running / no CLI). Operates on files directly; note the limitations (won't resolve aliases or [[link#heading]]):

VAULT="${CONTEXT_KIT_OBSIDIAN_VAULT:-${CLAUDE_PLUGIN_OPTION_VAULT_PATH:-.}}"
rg -l '\[\[Project X' "$VAULT"           # approx backlinks
rg -l '(^|\s)#decision' "$VAULT"         # notes with a tag
fd -e md . "$VAULT"                      # all notes

If rtk is installed, rtk rg -l … compacts output while keeping -l raw, so the piped note paths in step 2 stay intact. obsidian and rag aren't rtk-wrapped — they pass through unchanged.

2. Rerank semantically

Pipe candidate paths into local-rag's allowlist:

obsidian backlinks file="Project X" | rag query "open risks and mitigations" --name notes --allowlist -
rg -l '(^|\s)#decision' "$VAULT"        | rag query "why did we choose X"      --name notes --allowlist -

(Index the vault first: rag index "$VAULT" --name notes.)

3. Pin exact lines

rag returns path > heading + snippet. Use rg to jump to the exact lines.

Scope

This plugin only bridges retrieval. For authoring Obsidian notes, Bases, or Canvas, install kepano/obsidian-skills (the Obsidian founder's MIT skills) and use the official obsidian CLI.
