how is this anything other than advanced context pollution?

I hear you maybe my summary of the tool does give this impression.

Here are actual small use cases that work for me:

- Aggregate the markdown files of a git project in one place. I can version them, review them, dump them, search efficiently into them. Useful to me before launching long agentic tasks, I specify all I want to beforehand.

- "Cron" checks on new versions of libraries. This works without specific APIs or any setup. A document is maintained with the latest seen version in a specific path of the document base. I also had good results tracking new stars and user adding them with this.

- Press review / OSINT I built myself a "President Daily Brief" Same thing. It can "reason" given the old daily briefs and assess if the situation is worsening or not on a specific issue, and make basic forecasts. It tracked down the current Ebola crisis before it went mainstream for me and predicted correctly it would worsen.

I guess I use this for long term memory basically, where I keep ownership of long term knowledge locally. It's more a metaCerebralCortex, and openClaw "dreams" are the hippocampus coalescing these memories at night.

Also, please note each document in base has a virtual "path", so beyond tags and search you can pin down on a specific domain. It is structured as a tree.

I do understand that if I were to build a harness this would possibly not be a good fit for the core of it.

Does this make sense to you, or would you just basically do without such a thing at all to keep each agentic task context clean(er) ?
