Organize Uncategorized FreshRSS Feeds

Go through all feeds in the Uncategorized folder, sample their content, and assign each to the best-fitting category.

Environment

FRESHRSS_URL - Base URL of FreshRSS instance
FRESHRSS_API_USER - API username
FRESHRSS_API_PASSWORD - API password

Procedure

1. Authenticate

AUTH_TOKEN=$(curl -s -X POST "$FRESHRSS_URL/api/greader.php/accounts/ClientLogin" \
  -d "Email=$FRESHRSS_API_USER" \
  -d "Passwd=$FRESHRSS_API_PASSWORD" | grep -oP 'Auth=\K.*')

2. Fetch existing categories

curl -s "$FRESHRSS_URL/api/greader.php/reader/api/0/tag/list?output=json" \
  -H "Authorization: GoogleLogin auth=$AUTH_TOKEN" | jq -r '.tags[].id' | grep 'label/' | sed 's|user/-/label/||'

Keep this list for matching. Note the naming style (title case, short names).

3. Fetch uncategorized feeds

curl -s "$FRESHRSS_URL/api/greader.php/reader/api/0/subscription/list?output=json" \
  -H "Authorization: GoogleLogin auth=$AUTH_TOKEN" | jq '[.subscriptions[] | select(.categories | length == 0 or (.categories | all(.label == "Uncategorized")))] | .[] | {id, title, url: .htmlUrl}'

If there are no uncategorized feeds, inform the user and stop.

4. Sample and categorize each feed

For each uncategorized feed:

Sample the feed using WebFetch on the feed's htmlUrl (or its RSS URL if htmlUrl is missing). Read the title, description, and a few recent post titles to understand its topic.
Infer the best category. Compare the feed content against existing categories. Prefer existing categories. Only propose a new category if nothing fits, keeping the name short and consistent with existing style.
Collect a proposal with: feed title, inferred category, and brief rationale (a few words).

5. Present all proposals to the user

Show a summary table of all feeds and their proposed categories. Use AskUserQuestion to confirm the batch. Include:

Feed name
Proposed category (with "(new)" suffix if it would create a new category)
Brief rationale

Let the user approve all, reject all, or provide specific overrides. If the user provides overrides, apply those instead.

6. Apply categorizations

For each approved feed:

curl -s -X POST "$FRESHRSS_URL/api/greader.php/reader/api/0/subscription/edit" \
  -H "Authorization: GoogleLogin auth=$AUTH_TOKEN" \
  -d "ac=edit" \
  -d "s=FEED_ID" \
  -d "a=user/-/label/CATEGORY_NAME" \
  -d "r=user/-/label/Uncategorized"

Use r=user/-/label/Uncategorized to remove the old label if present.

7. Output results

Print a summary of what was done:

Number of feeds categorized
List of feeds with their new categories
Any new categories that were created
Any feeds that were skipped or left uncategorized

Notes

Token is session-based, get a fresh one each invocation.
Feed IDs use format feed/https://... or feed/NUMBER.
Batch the proposals so the user only needs to approve once, not per-feed.
If a feed's website is unreachable or gives no useful content, note it in the summary and skip it rather than guessing.
Fever API is read-only, always use the GReader API for mutations.
