Obsidian RAG Bridge

productivity-skills

A Claude Code plugin marketplace for information retrieval. It bundles complementary retrieval modalities — lexical, structural, structured-data, history, semantic (RAG), and graph — plus a routing agent that picks and composes them. Everything runs locally; the RAG layer keeps your corpus on your machine.

Install

/plugin marketplace add mbeacom/productivity-skills

Then install what you need (installing code-search auto-installs retrieval-core):

/plugin install code-search@productivity-skills     # lexical/structural/data/history search
/plugin install local-rag@productivity-skills        # local semantic search (turbovec + ollama)
/plugin install obsidian@productivity-skills          # Obsidian vault → RAG bridge

Plugins

Plugin	What it does
retrieval-core	The spine: a retrieval-strategist agent + retrieval-strategy skill that choose and compose modalities. Other plugins depend on it.
code-search	Lexical (rg/fd), structural (ast-grep/semgrep), structured-data (jq/yq/gron), history (git pickaxe/difftastic), structured rewrite (comby), metrics (tokei/scc), and non-code docs (rga/pandoc/pdftotext). Two skills: code-search (code) and data-and-docs-search (data/docs).
local-rag	Fully-local semantic search: a bin/rag CLI that chunks a corpus, embeds it with ollama, and indexes it with turbovec. Notes-first, corpus-agnostic, with incremental indexing and hybrid --allowlist retrieval.
obsidian	A skill-only RAG bridge: turn an Obsidian vault's graph/tags (official obsidian CLI, or rg fallback) into a candidate set fed to local-rag. For authoring/Bases/Canvas, use kepano/obsidian-skills.

Requirements

The skills degrade gracefully and tell you what's missing.

• code-search — needs rg (ripgrep); the rest are optional. Run bash plugins/code-search/scripts/check-tools.sh to see what's installed and the brew install … line for the rest.
• local-rag — needs uv (the rag CLI is bootstrapped into a venv automatically on session start) and a running ollama with an embedding model: ollama serve + ollama pull nomic-embed-text.
• obsidian — optional: the official obsidian CLI (with Obsidian running) for graph-accurate queries; otherwise falls back to rg/fd. Set your vault path in the plugin's config (vault_path).

Usage

Once installed, Claude invokes the skills automatically based on your task. The retrieval-strategist agent (or the retrieval-strategy skill) decides which modality fits — and they compose.

Pick a modality by what you know:

You know…	Modality	Example
an exact token / regex / filename	lexical	rg -t py 'def login' · fd -e ts
the code shape, not the text	structural	sg -p 'logger.debug($$$)' --lang js
a JSON/YAML schema path	structured-data	jq '.scripts' package.json · gron x.json | rg token
when/why code changed	history	git log -S'retry' -- src/
only the meaning/intent	semantic (RAG)	rag query "how do we handle backoff" --name notes
the corpus is an Obsidian vault	graph	obsidian backlinks file="Project X"

Semantic search (local-rag):

ollama pull nomic-embed-text                 # once
rag index /path/to/vault --name notes        # build/update (incremental)
rag query "open questions about billing" --name notes --k 8
rag status --name notes                       # counts, model, dim

Hybrid retrieval (the payoff) — narrow with the graph/lexical, rerank with vectors:

# Obsidian graph → semantic rerank (official CLI)
obsidian backlinks file="Project X" | rag query "open risks" --name notes --allowlist -

# rg fallback when Obsidian isn't running ($VAULT defaults to the plugin's configured vault_path)
VAULT="${CLAUDE_PLUGIN_OPTION_VAULT_PATH:-.}"
rg -l '#decision' "$VAULT" | rag query "why did we choose X" --name notes --allowlist -

rag returns path > heading + a snippet; follow up with rg to pin exact lines.

See docs/ARCHITECTURE.md for the modality model and how the plugins fit together.
