How to Transform 3 Years of Thinking into Assets: Accelerate Feedback with Claude Cowork

Claude Cowork: The Ultimate Engine for Objectively Viewing Your Own Thought Evolution
I had been pondering whether Claude Cowork actually has any practical uses. Then I discovered a new way to use it. Cowork is a work companion that autonomously executes multiple tasks based on massive amounts of data that surpass what a standard chat can handle.
As you know, Claude Cowork is not merely a chat tool. It is an AI agent that directly accesses your local file system (in my case, Obsidian) and autonomously completes tasks. You can either:
- Place your Obsidian vault in a folder that Cowork can access, or
- Use a combination of a local REST API + Obsidian MCP Tools to have Cowork retrieve information via MCP.
Both approaches work effectively.
What makes this tool truly disruptive is its ability to execute against three years of my living‑thought data with precision and speed comparable to the Observe and Orient phases of the OODA loop (Observe, Orient, Decide, Act). Sounds pretentious, right?
Why Bother Using Claude Cowork?
Human memory is vague and conveniently rewritten. Extracting every single description on a specific theme from three years of notes—numbering in the thousands—is humanly impossible. Simple word searches return only a fraction of the relevant information and ignore intent. Claude Cowork autonomously repeats searching and browsing, comprehensively observing all data.
Breaking Through the Limits of Observe
- Comprehensive extraction: Goes beyond keyword matches to consider the intent behind each note.
- Speed: Processes thousands of notes in minutes rather than days.
Deepening Orient
By comparing the thinking habits of my three‑years‑ago self with my current self, the AI highlights:
- Shifts in subjects of interest
- Changes in word choice
- Emerging patterns or blind spots
These objective facts are things I could never have noticed on my own. This isn’t nostalgia; it’s an advanced metacognitive environment that uses my past self as a stepping stone toward new ideas.
From Retrieval to Analysis
Using Claude Cowork transforms a simple Retrieval‑Augmented Generation (RAG) setup (e.g., Obsidian + Dify) into comprehensive information retrieval and analysis. The workflow I run looks like this:
- Observe – Scan all notes containing my views on generative AI from 2023 to the present (2026).
- Orient – Analyze chronologically when and through which technological breakthroughs my thinking changed.
- Insight – From that trajectory, surface blind spots that I should focus on in the next year.

Previously, this required several days of reading through past notes. With Claude Cowork, intermediate analysis files are generated in the working folder, and a map of my own thinking is produced in just minutes. This is not mere summarization—it is prototyping for the future through dialogue with my past self.
Reusing PKM as an Asset
In uncertain times, clinging to past success stories is unproductive. Your historical data—what you thought, how you experimented—is a unique asset that belongs to no one else. Claude Cowork turns that data from a static record into a “power plant” for generating new ideas.
Final Thoughts
Stop using Claude Cowork as just a summarization tool. It is a partner for increasing the speed of your thinking and running the OODA loop faster than anyone else. Whether you let three years of data sleep as mere records or turn it into a catalyst for your next ideas depends on how you master Cowork as an autonomous agent.
I will continue to gaze into this ultimate mirror and refine my thinking day after day.
