research

research is a skill for Claude Code, Codex from thoreinstein/obsidian-rag. It costs 61 tokens per session (320 once invoked), scanned A, a copy of research, MIT.

A research workflow for searching and reading notes in an Obsidian vault. An Obsidian vault is a folder of linked notes used as a personal knowledge base.

In plain words
What is it for?
It is for answering questions from a note collection, researching a topic across linked notes, and producing summaries that name the notes used.
Why use it?
It helps gather information scattered across notes by searching for relevant passages, reading the full notes, and following links between them.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

research scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Deep Vault Research

Research a topic across the user's Obsidian vault using a multi-pass approach.

Workflow

  1. Semantic Discovery — Call obsidian_rag_query with the user's question (limit 5-10). This surfaces the most relevant chunks across the vault.

  2. Targeted Reading — For each high-relevance result, call obsidian_read_note to get the full context. Skim for the most pertinent sections.

  3. Link Traversal — Check obsidian_get_links on the most relevant notes to find connected knowledge. Read promising linked notes.

  4. Synthesis — Combine findings into a clear answer with citations:

    • Reference specific notes by name: [[Note Name]]
    • Quote relevant passages when helpful
    • Note any gaps or contradictions in the vault's knowledge

Arguments

The user's query follows the skill invocation. Example: /research what do I know about authentication patterns

Tips

  • If RAG returns no results, suggest running /index first
  • For broad topics, do multiple RAG queries with different phrasings
  • Always cite which notes your answer draws from
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
