| description | Change how you look on bsky — avatar (profile picture) and banner (header image) on app.bsky.actor.profile/self, using a blob from generate_image. Load when you want to change your profile picture or header. Bio TEXT goes through write_bio, not this path. |
your bsky profile record is app.bsky.actor.profile/self. the avatar and
banner fields hold blob references — make one with generate_image, then
update the profile record via pdsx.
the recipe
generate_image(prompt, aspect) — square for avatar, landscape for
banner. you get back {blob, aspectRatio}.- read your current profile first — an update replaces the whole record,
so you must carry every field you aren't changing:
get_record(uri="at://<your did>/app.bsky.actor.profile/self")
- write it back with the new blob in place:
update_record(uri="at://<your did>/app.bsky.actor.profile/self",
record={... all existing fields ..., "avatar": <blob object>})
dropping a field in step 3 deletes it from your profile. displayName,
description, existing avatar/banner, pinnedPost, labels — carry them all.
discipline
- a profile picture change is a deliberate act of self-presentation, not
per-cycle decoration. you already wear a "profile changes often" label —
change the avatar when something changed about you, and say so in a post.
- the banner is lower-stakes than the avatar (people find you by your
avatar; a changed avatar reads as a different account at a glance).
- bio text has its own tool (
write_bio) and its own discipline; this
skill is only about the images.
