⚠️ PREREQUISITES — READ THIS FIRST

MCP gate (before ANY Data Store operation): Confirm the ZohoMCP_* meta-tools (ZohoMCP_getSchema, ZohoMCP_executeTool, ZohoMCP_listTools, ZohoMCP_getFeatures) are present in your tool list — that is the "MCP connected" signal. (The CatalystbyZoho_* names never appear as tools; they are tool_name values passed to ZohoMCP_executeTool.) If the meta-tools are NOT present → STOP: do not write code, scaffold files, or instruct Console steps — load the catalyst-zoho-mcp skill, guide the user through MCP setup, and resume only once they appear.

Once the tools are visible, complete the canonical pre-flight once per session (establish + verify org/project) → ../catalyst-basics/references/preflight.md, then continue to "How It Works". Verify table access with CatalystbyZoho_List_All_Tables before create/update operations.

How It Works

1. Create or locate the table via MCP — Creating a table? Invoke CatalystbyZoho_Create_Table via ZohoMCP_executeTool (schema first with ZohoMCP_getSchema). Do NOT instruct the user to open the Catalyst Console or create the table manually. Reading/writing data? Invoke CatalystbyZoho_List_All_Tables (same way) to get table IDs. Never ask the user to copy table IDs.
2. Load references/datastore-basics.md — for CRUD operations, ZCQL syntax, result unwrapping, and permissions setup.
3. Unwrap ZCQL results — Always remind: rows.map(r => r.TableName). Raw ZCQL results are wrapped; accessing without unwrapping is the #1 Data Store bug.
4. Permissions — App User permissions are OFF by default. If the query involves a logged-in user reading data, check Console → Table → Scopes and Permissions.
5. Pagination — ZCQL max 300 rows per query. Use LIMIT offset, count for larger datasets.

Security Checklist

• App User write permissions are off by default. The App User role has SELECT enabled by default, but INSERT, UPDATE, and DELETE must be manually enabled per table. Go to Console → Table → Scopes and Permissions → App User role → check Insert/Update/Delete for any table your authenticated users need to write.
• App Administrator has all permissions by default. Never assign the App Administrator role to regular end-users — it grants full read/write/delete access to all tables.
