save-url

Saves a URL to the user's Wallabag instance using OAuth2 password grant authentication. Supports optional tags and a custom title.

<quick_start> /wallabag:save-url https://example.com/article

With tags: /wallabag:save-url https://example.com/article #tag1 #tag2

With title: /wallabag:save-url https://example.com/article "My custom title" </quick_start>

Parse `env=` from `$ARGUMENTS` before any other processing. Strip it from remaining arguments. Default to `""` (empty string). Credential file: `~/.claude/channels/wallabag/${ENV}.env`. Omit `env=` from suggested commands when ENV is empty. Load credentials from `~/.claude/channels/wallabag/${ENV}.env`. If the file doesn't exist or any key is missing, tell the user to run `/wallabag:configure-wallabag env=$ENV setup` first and stop.

<argument_parsing> Parse $ARGUMENTS (after stripping env=) for:

• url — the URL to save (required; stop with error if missing)
• tags — comma-separated list of tags if any #tag tokens are present
• title — custom title if a quoted string is present (optional) </argument_parsing>

**Authenticate:**

source ~/.claude/channels/wallabag/${ENV}.env
TOKEN=$(http --ignore-stdin -f POST "${WALLABAG_URL%/}/oauth/v2/token" \
  grant_type=password \
  client_id="$WALLABAG_CLIENT_ID" \
  client_secret="$WALLABAG_CLIENT_SECRET" \
  username="$WALLABAG_USERNAME" \
  password="$WALLABAG_PASSWORD" | grep -o '"access_token":"[^"]*"' | cut -d'"' -f4)

If the token is empty, report an authentication failure and suggest running /wallabag:configure-wallabag env=$ENV to verify credentials.

Save the entry:

http --ignore-stdin POST "${WALLABAG_URL%/}/api/entries.json" \
  "Authorization:Bearer $TOKEN" \
  url="$URL" \
  tags="$TAGS" \
  title="$TITLE"

Omit tags and title fields if not provided.

• HTTP 401 — token expired or invalid; suggest re-running /wallabag:configure-wallabag env=$ENV.
• Other error — show the status code and response body. </display_results>

<success_criteria>

• URL saved to Wallabag and entry ID reported
• Authentication failure gives clear guidance to reconfigure
