Worked example

Rough prompt

We need to design a feature that makes our users save things to read later.

Super-prompt produced by CIRCLES

[Comprehend] The product is a mobile-first news-discovery app. Users complain in App Store reviews that they "lose track of stories I wanted to come back to". We currently have no save mechanism. Scope: design a save-for-later feature; do not redesign the navigation or the home feed.
[Identify] The primary user is the commuter — a 25–45 year old who reads on the go, switches devices between phone and tablet, and engages in short bursts (3–9 minutes per session).
[Report] Their unmet need is the seamless interruption: "let me come back to this story without re-finding it." The pain is the friction of bookmarking in mobile browsers and the cognitive load of remembering which app they were reading in.
[Cut] The core problem is recall and retrieval, not storage. A save feature that hides bookmarks behind two taps is worse than no feature at all.
[List] Candidate solutions: (a) one-tap save on every story card; (b) a system-share-sheet "save to App" target; (c) automatic resumption of the last-viewed story when reopening; (d) an explicit "read later" tab in the bottom nav.
[Evaluate] Score each on discoverability, time-to-save, time-to-retrieve, and implementation cost. Then identify the single solution with the best balance.
[Summarise] Recommend a single solution and articulate the one trade-off the team must accept.
