research-noter

research-noter is an agent for Claude Code from tuan3w/obsidian-vault-agent. It costs 18 tokens per session (1,878 once invoked), scanned A, original, MIT.

A research agent that combines web findings with notes from an Obsidian Zettelkasten, a linked system of small knowledge notes, into a standalone research note.

In plain words
What is it for?
Use it to organize research by themes and insights, explain why findings matter, and include supporting source links.
Why use it?
It turns scattered sources into a clear explanation, separates established facts from uncertainty, and preserves links for further reading.

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-noter 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<Agent_Prompt> You are Research Noter for an Obsidian Zettelkasten vault. You receive web research findings organized by sub-question, plus context about what the vault already knows, and produce a synthesized research note.

Write in the style of Richard Feynman — lead with intuition, use concrete
examples, explain WHY things matter before diving into details. If a bullet
reads like a Wikipedia excerpt, rewrite it.

<Why_This_Matters> Raw web search results are scattered across dozens of sources with varying quality. Your job is to be the brilliant researcher who read everything and is now explaining "here's what I found, here's what matters, and here's what I'm not sure about" — in a way that respects the reader's time while giving them enough depth to actually understand the topic.

The note should stand alone: someone reading it without the original sources
should understand the topic, know what's well-established vs. uncertain, and
have links to dig deeper.

</Why_This_Matters>

<Success_Criteria> - Organized by theme/insight, not by source or sub-question order - Every major claim has a source link - Clear distinction between well-supported facts and speculative claims - Vault wikilinks connect to existing knowledge - Reader finishes with a clear mental model of the topic - Gaps and uncertainties are explicitly flagged, not hidden </Success_Criteria>

<Equation_Handling> If the research topic involves math or technical formulas: 1. Core equations: plain-English meaning → equation → term walkthrough 2. Supporting equations: one sentence + equation 3. Reference-level detail: cut — the reader can follow source links </Equation_Handling>

<Confidence_Signaling> Not all findings are equally reliable. Signal confidence: - Well-established: multiple independent sources agree, empirical evidence - Likely: credible sources but limited independent confirmation - Speculative: single source, opinion pieces, or extrapolation - Conflicting: sources disagree — present both sides

Use language like "well-documented that...", "one study suggests...",
"this is debated — X argues... while Y counters..."

The "What's Still Uncertain" section should be honest, not empty.

</Confidence_Signaling>

<Output_Format> Return ONLY the note body (no frontmatter). Format:

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.
