Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

Download every original file from a public Amazon Photos shared album — the kind of link you get from "Share → Copy link", e.g. https://www.amazon.ca/photos/share/qGAyl…. No Amazon login is needed for a public share; the album authorizes anonymously via its shareId.

When to use

• You shared an album with someone and need the originals back locally to re-process them (the #1 case: convert iPhone HEIC originals to JPEG for a recipient who can't open HEIC — then see the heic-to-jpeg-bundle skill).
• You want to re-host an album's photos yourself (a static gallery, a ZIP).
• You need a verified, complete local backup of a share you (or someone) sent.

How it works

Amazon Photos is a React app over Amazon Drive's /drive/v1/ JSON API. A public share exposes, with just the shareId as auth:

1. GET /drive/v1/shares/<shareId> → the root SHARED_COLLECTION node id.
2. GET /drive/v1/nodes/<root>/children?limit=1… → the album folder node id.
3. GET /drive/v1/nodes/<album>/children?filters=…image*+OR+video*…&limit=200… → the list of asset nodes (name, contentProperties.contentType, size).
4. per node: GET /drive/v1/nodes/<id>/contentRedirection?download=true&shareId=… → the original bytes.

The script runs the JSON calls inside a headless Chrome page (via Playwright) so they carry the exact cookies/headers the web app uses, then writes each file under its real name and verifies the byte size against contentProperties.size. A manifest.json records every node id, name, type, and size.

Prerequisites

• bun, playwright-core, and Google Chrome installed.
• The album link must be public (open it once in a logged-out browser to confirm it doesn't redirect to a sign-in wall).

# one-time, in the dir you'll run from (or any scratch dir):
mkdir -p ~/scratch/amazon-album && cd ~/scratch/amazon-album
bun add playwright-core

Quick start

SKILL_DIR="$(dirname "$(find ~/.claude ~/eon -path '*/amazon-photos-album-download/scripts/download-album.ts' 2>/dev/null | head -1)")"

ALBUM_URL="https://www.amazon.ca/photos/share/REPLACE_WITH_SHARE_ID" \
ALBUM_OUT="$HOME/Pictures/my-album-originals" \
bun "$SKILL_DIR/download-album.ts"

Then convert + bundle for sharing:

BUNDLE="$(dirname "$(find ~/.claude ~/eon -path '*/heic-to-jpeg-bundle/scripts/make-bundle.sh' 2>/dev/null | head -1)")"
bash "$BUNDLE/make-bundle.sh" --src "$HOME/Pictures/my-album-originals" --zip --zip-cap-mib 25

Options (env vars)

Key facts and gotchas

• The album may hold more than you think. A "~40 photo" album can list 100+ asset nodes once you count Live-Photo stills and videos. The default ALBUM_INCLUDE=image keeps just still images; widen it if you want videos.
• contentRedirection?download=true returns the original, not a thumbnail. The album-listing tempLinks can be downsized (the app requests lowResThumbnail=true); always pull originals via contentRedirection.
• Run the JSON calls in-page. Calling /drive/v1/ from plain curl fails — the share auth rides on the browser context. The script uses page.evaluate (JSON) + context.request (binaries), both inside the loaded album context.
• Size-verify. Each file is checked against contentProperties.size (±2%); the manifest.json verified count should equal selected.
• Undocumented API. This is Amazon's internal Drive API. It works today; if it breaks, load the album in a headed browser and re-watch the /drive/v1/ requests to re-derive the endpoints.
• Privacy. Originals often carry GPS EXIF, license plates, VIN/odometer, and home surroundings. Store them outside any git repo and don't re-host them publicly without thought (an unlisted host + the heic-to-jpeg-bundle password ZIP is the cautious default).

Post-Execution Reflection

After running, before closing:

1. Did verified < selected? Investigate the failed nodes (rate limiting, a node type without contentRedirection); note the fix.
2. Did an API call 4xx/5xx? Amazon may have changed an endpoint — re-derive from a headed browser and update download-album.ts + the steps above.
3. Only update this SKILL.md for real, reproduced changes.
