+name: trello-llm-arranged-card
+description: Use when the user wants to create a Trello card in the NixCN CMS board's LLM Arranged list from natural-language instructions, and the target card should be written safely with exact board/list validation.
+---
+
+# Trello LLM Arranged Card
+
+## Overview
+
+Create cards only in `NixCN CMS / LLM Arranged`.
+
+Core rule: validate the exact board and exact list before writing. Never guess, never fall back to the active board, and never create the card if the target cannot be matched exactly.
+
+## When to Use
+
+Use this skill when the user wants Claude to turn an instruction into a Trello card in:
+- board: `NixCN CMS`
+- list: `LLM Arranged`
+
+Do not use this skill for:
+- moving cards
+- editing existing cards
+- creating boards or lists
+- writing cards to any other board/list unless the user explicitly asks to change this skill
+
+## Required Target
+
+Always use these exact values:
+
+- `boardId`: `69b25ef1ed862e287ff0b657`
+- `boardName`: `NixCN CMS`
+- `listId`: `69c49bf90863369ce20526ec`
+- `listName`: `LLM Arranged`
+
+Always verify the board and list before writing.
+
+## Input Mapping
+
+Minimum required field:
+- card title
+
+Default mapping from natural language:
+- short primary request -> card title
+- remaining details -> card description
+
+If the user provides structured fields, map them as:
+- `title:` -> card name
+- `description:` or remaining body -> card description
+- `due:` -> due date in ISO 8601
+- `start:` -> start date in `YYYY-MM-DD`
+- `labels:` -> labels, only if explicitly provided
+
+If labels are provided by name, first call `mcp__trello__get_board_labels` with `boardId: 69b25ef1ed862e287ff0b657`, require exact name matches, then pass the matched label IDs. If any label cannot be matched exactly, ask the user instead of guessing.
+
+Do not infer labels, due dates, assignees, or checklists unless the user explicitly asks.
+If the user provides unsupported details, preserve them in the card description instead of dropping them silently.
+If a natural-language date cannot be resolved confidently, ask a follow-up question.
+
+## Workflow
+
+### 1. Validate destination
+
+Before creating the card:
+1. call `mcp__trello__list_boards` and require an exact board name match for `NixCN CMS` with `id: 69b25ef1ed862e287ff0b657`
+2. call `mcp__trello__get_lists` with `boardId: 69b25ef1ed862e287ff0b657`
+3. confirm `listId: 69c49bf90863369ce20526ec` exists in that board with exact list name `LLM Arranged`
+4. use the exact `boardId` and exact `listId` when creating the card
+
+If exact validation fails, stop and tell the user what is missing.
+
+### 2. Validate content
+
+If there is no clear card title, ask for one.
+
+If the user gives only a loose idea and wants help organizing it, you may propose a cleaned-up title and description first, but do not create the card until the user confirms the synthesized content.
+
+### 3. Check duplicates
+
+Before creating the card, call `mcp__trello__get_cards_by_list_id` with:
+- `boardId: 69b25ef1ed862e287ff0b657`
+- `listId: 69c49bf90863369ce20526ec`
+
+If a near-identical card already exists, warn the user and ask whether to create another one.
+
+### 4. Create the card
+
+Use `mcp__trello__add_card_to_list` with:
+- `boardId: 69b25ef1ed862e287ff0b657`
+- `listId: 69c49bf90863369ce20526ec`
+- `name: <resolved title>`
+- optional `description`, `dueDate`, `start`, `labels`
+
+### 5. Return auditable output
+
+After creation, always report:
+- board name
+- list name
+- card name
+- card id
+- card url
+
+## Safety Rules
+
+- Always pass `boardId: 69b25ef1ed862e287ff0b657` explicitly on Trello calls used by this skill.
+- Never use the active board as an implicit fallback.
+- Never fuzzy-match a board or list name.
+- Never create in `Backlog`, `To Do`, or any other list as a fallback.
+- Never silently drop user-provided details.
+- Never guess labels or due dates.
+- If the request is ambiguous, ask instead of writing.
+
+## Quick Reference
+
+| Need | Action |
+|---|---|
+| User wants a card created from plain language | Extract title, put remaining details in description |
+| Title is unclear | Ask for title or propose one for confirmation |
+| Target list missing or renamed | Stop and report exact mismatch |
+| User repeats same request | Warn that creation is not idempotent and may duplicate cards |
+
+## Common Mistakes
+
+- **Using the current active board** instead of the fixed destination — forbidden.
+- **Creating with only a vague title** when the instruction is too ambiguous — ask first.
+- **Guessing metadata** like labels or due dates — only use explicit user input.
+- **Reporting only “done”** — always return card id and URL.
