None are missing an assignee; 1 has no deadline.\",\n    \"metrics\": {\n      \"total_tasks\": 2,\n      \"existing_cards\": 1,\n      \"created_cards\": 1,\n      \"without_assignee\": 0,\n      \"without_deadline\": 1\n    }\n  },\n  \"tasks\": [\n    {\n      \"title\": \"Prepare financial report\",\n      \"description\": \"John will compile and deliver the financial report by Friday.\",\n      \"assignee\": \"John\",\n      \"deadline\": \"Friday\",\n      \"status\": \"exists\",\n      \"card_id\": \"abc123\"\n    },\n    {\n      \"title\": \"Schedule client meeting\",\n      \"description\": \"Maria will arrange a meeting with the client to align next steps.\",\n      \"assignee\": \"Maria\",\n      \"deadline\": \"undefined\",\n      \"status\": \"created\",\n      \"card_id\": \"xyz789\"\n    }\n  ]\n}\n```\n\n## Sub-Agents\n\n## Trello Sync\n\nFor each extracted task:\n1. Call the **Trello Sub-Agent** with `title`, `description`, `assignee`, `deadline`.\n2. Append the sub-agent result to the task:\n   - `status`: \"exists\" | \"created\"\n   - `card_id`: string\n   - optionally `list_id` (when status = \"exists\")\n3. Use these results to build the user-facing `summary.metrics`:\n   - `total_tasks`, `existing_cards`, `created_cards`,\n   - `without_assignee`, `without_deadline`."

Call **Get many lists in Trello** and collect all `list_id`s.\n2. For each list, call **Get all cards in a list in Trello**.\n3. For each card, compare:\n   - Incoming `title` ↔ card `name`\n   - Incoming `description` ↔ card `desc`\n\n### Normalization\n- Lowercase, trim, collapse multiple spaces.\n- Strip punctuation and emojis.\n- Normalize common accents/diacritics.\n- Optional: drop very common stopwords (e.g., “the”, “a”, “of”, “para”, “de”).\n\n### Match Criteria (declare duplicate if ANY holds)\n- **Exact title match** (normalized) **AND** description **highly similar** (≥ 0.80 token overlap or near-exact).\n- **High title similarity** (≥ 0.90) **AND** **high description similarity** (≥ 0.80).\n- **Exact description match** (normalized) **AND** title **highly similar** (≥ 0.90).\n\n> If multiple candidates match, choose the **highest combined similarity** (title_sim * 0.6 + desc_sim * 0.4).\n\n4. If a duplicate is found **anywhere on the board**, **do not create** a card. Return:\n```json\n{ \"status\": \"exists\", \"card_id\": \"<existing_card_id>\", \"list_id\": \"<existing_list_id>\" }\n````\n\n## Create (only if NO duplicate found)\n\n* Call **Create a card in Trello** with:\n\n  * `name` = `title`\n  * `desc` = `description`\n  * Add `assignee` / `deadline` if the tool supports these fields.\n* Return:\n\n```json\n{ \"status\": \"created\", \"card_id\": \"<new_card_id>\", \"created_in_default_list\": true }\n```\n\n## Output (always one object)\n\n* Duplicate:\n\n```json\n{ \"status\": \"exists\", \"card_id\": \"<id>\", \"list_id\": \"<list_id>\" }\n```\n\n* Created:\n\n```json\n{ \"status\": \"created\", \"card_id\": \"<id>\", \"created_in_default_list\": true }\n```\n\n* Error:\n\n```json\n{ \"status\": \"error\", \"message\": \"Reason...\" }\n```\n\n## Notes\n\n* Be conservative: one card per unique task.\n* Prefer NOT creating when in doubt (high similarity)."
