PURPOSE:
            Retrieve a list of negative keywords lists from the Metadata platform with optional name filtering.
            Use this tool to discover and search for specific negative keywords lists for campaign management and optimization.

            ACCOUNT LIMIT:
            WARNING: MAXIMUM 20 NEGATIVE KEYWORDS LISTS PER ACCOUNT
            Each account can have a maximum of 20 negative keyword lists. Use this tool to check your current list count
            and manage your existing lists. If you need to create a new list but have reached the limit, you'll need to
            delete or archive existing lists first.

            WHEN TO USE:
            - Browse all available negative keywords lists in the account
            - Search for specific negative keywords lists by name
            - Find negative keywords lists by partial name matching
            - Get all negative keywords lists data
            - Discover available negative keywords lists for campaign use
            - Check current list count to manage the 20-list limit

            KEY FEATURES:
            - NAME SEARCH: Filter by negative keywords list name for targeted searches (optional)
            - MULTIPLE SEARCH: Search for multiple list names at once with automatic deduplication
            - SIMPLE INTERFACE: Only name-based filtering, no pagination or sorting needed
            - LIST COUNTING: Use to verify your current count against the 20-list maximum

            NAME SEARCH:
            The optional 'name' parameter supports:
            1. Single name (string): Searches for one negative keywords list name
               - "branded" → Finds negative keywords list named "Branded"
               - "competitor" → Finds negative keywords list named "Competitor"
               - "generic" → Finds negative keywords list named "Generic"

            2. Multiple names (array of strings): Searches for multiple negative keywords lists at once
               - ["branded", "competitor", "generic"] → Aggregates results from all three searches
               - Makes separate API requests for each name and combines results
               - Automatically deduplicates lists by ID
               - Returns all unique negative keywords lists matching any of the provided names

            - Omit 'name' parameter to list all negative keywords lists without filtering
            - Both single and multiple searches support partial matching

            RESPONSE FORMAT:
            Returns a response with:
            {
              "data": [
                {
                  "name": "BRanded",
                  "id": 123
                },
                {
                  "name": "Competitor",
                  "id": 124
                }
              ]
            }

            COMMON USE CASES:
            1. List all negative keywords lists:
               list_negative_keywords_list()

            2. Search for "branded" negative keywords list:
               list_negative_keywords_list(name="branded")

            3. Find specific negative keywords list:
               list_negative_keywords_list(name="BRanded")

            4. Search for multiple negative keywords list names at once:
               list_negative_keywords_list(name=["branded", "competitor", "generic"])

            5. Search multiple negative keywords list names:
               list_negative_keywords_list(name=["competitor", "generic"])

            PARAMETERS:
            - name: Optional negative keywords list name or partial name to search for. Can be a string or array of strings.
                    Supports partial matching. Omit to list all negative keywords lists. (optional)

            PERFORMANCE TIPS:
            - Use name parameter for targeted searches to reduce result set
            - When searching multiple names, each name triggers a separate API request
              Use reasonable list sizes to avoid excessive API calls
            - Results are automatically deduplicated when searching multiple names

            EXAMPLES:
            - list_negative_keywords_list() - Get all negative keywords lists
            - list_negative_keywords_list(name="branded") - Search for branded negative keywords list
            - list_negative_keywords_list(name=["branded", "competitor"]) - Search multiple negative keywords lists
            - list_negative_keywords_list(name="competitor") - Find competitor negative keywords list
            - list_negative_keywords_list(name=["branded", "generic"]) - Multiple list names search

            CHANNEL SCOPE:
            BOTH search channels are supported: pass channel=MICROSOFT_ADS for Microsoft
            Ads (Bing) and channel=GOOGLE_ADS for Google. The two channels hold SEPARATE
            lists, so never substitute one channel for the other to get "close enough"
            results.
