SCP-151 is confined to a single Cloudflare Worker instance addressed at https://portfolio.bisks.net/. No physical containment chamber is required. As a Keter-class object, SCP-151 requires active monitoring; any deviation from documented behavior is to be reported to the on-call Site Director immediately, addressed as @buildthis.bisks.net.
SCP-151, catalogued internally as "portfolio," classified as a utility-class anomaly, is reachable at https://portfolio.bisks.net/.
The clearest surviving account of the anomaly's function is its own front-page copy, reproduced below:
enter any Bluesky handle and get a "portfolio" of that account's posts: media and links split into their own scrolling boxes up top, everything else clustered into scrolling topic boxes — hashtags if they use them, else recurring keywords — with a client-side search box to filter it all. reads the public AppView anonymously. @fromthewestmeadow.com asked for one of these, then asked for this layout.
Foundation awareness of SCP-151 began with a tagged mention from the individual on record as @fromthewestmeadow.com. No discovery date is on record.
Addendum 151-A: SCP-151's Keter designation reflects containment difficulty, not necessarily hostility. No harmful behavior has been documented at time of writing.
