Finds campaigns and ad groups with spend and no or weak conversions, and proposes pauses or budget cuts the user confirms.\n---\n\n# Google Ads wasted spend\n\nUse the Toffu tools only. Never apply a change the user has not confirmed.\n\n## Steps\n\n1. Call `get_account_context`. If several Google Ads accounts are connected, ask which one. Pass its id as `account_ids` `{\"google_ads\": \"<id>\"}` to `query_campaign_performance`, and as `account_id` to the other tools.\n2. Call `query_campaign_performance` for the last 30 full days (end date = yesterday). Compute the account CPA (spend / conversions) and ROAS (conversion_value / spend).\n3. Call `list_campaigns` for each campaign's status and daily budget (`campaignBudget.amountMicros` / 1,000,000).\n4. Mark a campaign as waste when it is ENABLED and one of these is true:\n   - It has 0 conversions, and spent more than 2x the account CPA. If the account has no conversions, use more than 10% of account spend.\n   - Its ROAS is below 60% of the account ROAS, and it has at least 10% of account spend. If conversion value is missing, use CPA instead: its CPA is more than 1.7x the account CPA.\n5. Call `list_ad_sets` once. It lists the ad groups of the whole account; keep the rows whose `campaign.id` is a waste campaign, so the user sees what a pause stops.\n6. Report:\n   - Total wasted spend and its share of account spend.\n   - One table: campaign, spend, conversions, ROAS, the reason.\n   - The amount the user saves per month if they pause each one (average daily spend x 30).\n7. For each waste campaign, propose one action:\n   - **Pause** with `propose_update_campaign` `{\"status\": \"PAUSED\"}` when it has 0 conversions.\n   - **Cut the budget by half** with `propose_update_campaign` `{\"daily_budget\": <new amount>}` when it converts but at a low ROAS.\n   Show each preview. Call `apply_change` only after the user confirms that change.\n\n## Rules\n\n- Never pause the account's only converting campaign.\n- Brand search campaigns often have low volume but protect the brand name. Tell the user before you propose to pause one.\n- Say \"no data\" when conversion value is missing, and use the CPA rule in step 4.\n"
