Report only what’s new

A recurring Action can drift into repeating the same findings week after week. Deduplication fixes that: Chief reviews the Action’s previous results before writing the next one, so each run delivers genuinely new information.

How it turns on

Chief: Deduplication — avoiding repeat reports — How it turns on
Deduplication is wired to Save to Library. When you check Save each Action run’s output to my Library as a file with label and pick a Label, Chief automatically adds a line to the top of your prompt — something like “First, check the previous Action results in my Library regarding [your Label]… provide net new information without duplicating past results.” Because past runs are saved under that Label in your Library, each new run can read them and skip what it already covered. When this happens you’ll see a green notice in the dialog: “I’ve updated your prompt to use this label to check for past results before running.”

​
Turning it off

If you’d rather not deduplicate, click Undo in that green notice. Chief removes the auto-added line from your prompt, and runs will no longer compare against past results.
ℹ️ Good to know: The dedup line is just text inserted into your prompt — you can see it, edit it, or delete it like anything else you typed. If you delete it manually, Chief respects that and won’t re-add it.

FAQ

It only kicks in when Save to Library is on and at least one Label is selected — that Label is what Chief uses to find past results. Turn on Save to Library and pick a Label.
Yes. If there genuinely isn’t much new since the last run, a deduplicating Action will say so rather than repeat old findings. To get a full re-summary, click Undo on the dedup notice or run the Action without the dedup line.
No. Chief compares against the saved, Labeled runs in your Library, so Save to Library with a Label is required.
