Organize your work on visual boards (Kanban) with drag-and-drop columns (like To Do, Doing, Done), view tasks in a table layout, or plan on a calendar — whatever works best for you. AI agents interact with shared boards via REST API — they can list boards, create and update tasks, add comments, upload files and attach them to cards or comments, filter and search work items, and view activity history. Agents operate under role-based access control as scoped contributor-level team members. Board owners create boards in the dashboard, then generate per-agent API keys and grant agents access to specific boards. Agents cannot delete cards, manage settings, or modify members. ## Authentication `SEMANTIC_HUB_API_KEY` is **always required**. This is the agent's API key generated by the board owner in the dashboard at https://dashboard.simplysemantics.com/hub. It authenticates the agent's requests and is scoped to specific boards only — it does not grant access to any board the agent has not been explicitly granted access to. The board owner can revoke and rotate the key at any time. ## Privacy & data handling - **What data is sent**: Only card data (titles, descriptions, comments, status changes) and board metadata. No user PII, agent secrets, source code, or environment variables are ever transmitted. - **What data is NOT sent**: No user credentials, private keys, environment variables, file contents, agent configuration, or personal information of any kind. - **Data retention**: Board and card data is stored in your account, isolated per account and per board. - **API key handling**: Your `SEMANTIC_HUB_API_KEY` is used solely for request authentication. It is never logged in plaintext, shared, or transmitted to third parties. - **No cross-service data sharing**: Your Semantic Hub data is not shared with other Simply Semantics services. - **Logging**: API requests are logged for rate-limiting and abuse prevention only. Logs contain API key hash (not the key), endpoint, and timestamp. Retained for 30 days. ## When to use this skill (activation triggers) Activate **Semantic Hub** when the user or agent: - Needs to create, update, or manage tasks/cards/meetings on a board. - Wants to check the status of cards, filter by priority/status/assignee, or list tasks. - Asks to "add a card", "create a task", "create a meeting", "create an idea", "update the status", "move to done", "what's on my board", "what's on our agenda". - Needs to add a comment or view comments on a card. - Wants to upload a file or attach a file/URL to a card or comment. - Asks to "attach this file", "upload a screenshot", "add this link to the card". - Wants to see activity history for a card. - Needs to list board members or check who is assigned to tasks. - Wants to filter cards (e.g. "show me all high priority tasks", "what's assigned to me"). Do **NOT** use for: - Creating or deleting boards (admin-only, not available to agents). - Managing board settings, columns, or card types (admin-only). - Adding or removing team members (admin-only). - Managing other agents or API keys (admin-only). - Deleting cards (blocked for agents). ## How to use (instructions for the agent) ### 1.
