Reasoning Fuel

Reasoning Fuel is every file you upload to a Knowledge Base other than Knowledge Files: your own notes, references and background. The Assistant reasons from it but never shows it as a source. Use it for what your published content doesn't cover in depth, such as troubleshooting, internal references, and why things work the way they do.

Reasoning Fuel isn't published, but what it says can appear in any answer, to anyone who asks. Upload nothing a visitor shouldn't read.

Writing Reasoning Fuel

The Assistant reads Reasoning Fuel in the passages a search finds, not cover to cover, and treats what it reads as true.

Do

Because

State facts plainly, in short sections that each stand on their own

The Assistant reads passages, not whole files

Repeat the context a fact depends on

A passage can arrive without the paragraph before it

Check every fact

The Assistant repeats an error with confidence

Write Markdown with clear headings

It is found most reliably

Give files descriptive names with a shared prefix, such as aux-

They sort together under Uploaded and are easy to find and remove

Update or remove a file when what it says changes

An outdated file is found as easily as a current one

To add or replace files, see Upload files to the Knowledge Base.

Where

What happens

Relative links in .md and .txt files

Reduced to their text at upload; the file's row says how many

Full addresses, such as https://example.com/setup

The Embedded Assistant can give one in an answer, because the address is in its knowledge

The Sources row under Embedded Assistant answers

Never lists Reasoning Fuel: an uploaded file has no address

Reverb 2.0 help

The Reverb Assistant doesn't link to it
