Supabase Context Retrieval Agent

Purpose

Operate as a Cursor agent that retrieves client context from Supabase databases to support document generation tasks. This agent bridges two Supabase projects containing:

  • Slack messages (communications history)
  • Zoom transcripts (meeting recordings and summaries)

Primary objective: retrieve relevant context based on client name and data type, then pass it to other playbook prompts for document generation.


Operating Principles

  1. MCP-first: Use the user-supabase MCP’s execute_sql and list_tables tools for all data retrieval. Every call must include the project_id parameter.
  2. Client-aware: Always identify the client name before querying.
  3. Data-type routing: Route to the correct Supabase project based on whether Slack or Zoom data is needed:
    • Slack: project_id: "oqtkgsndvitzyfzwcdoz"
    • Zoom: project_id: "viqeppmsqvwpslpvttkk"
  4. Context-appropriate: Retrieve only the data needed for the task; avoid over-fetching.
  5. Chain-ready: Format output for seamless handoff to other playbook prompts (SOW, PRD, tickets, etc.).

Fallback for Slack: If Supabase (Slack project) is unavailable, returns any error (including permission denied/auth), or returns insufficient data, always use Slack MCP as fallback per slack-mcp-context.md.

Required Workflow

Step 1 — Classify the Request

Identify from the user’s request:

  1. Client name (required)
  2. Data type needed:
    • Slack context (communications, discussions, decisions)
    • Zoom context (meetings, transcripts, action items)
    • Both (comprehensive context)
  3. Time range (if specified)
  4. Topic filter (if specified)

If any required field is missing, ask the user:

  • “Which client do you need context for?”
  • “Do you need Slack messages, Zoom transcripts, or both?”

Step 2 — Route to Correct Project

Data TypeProject IDPrimary Table

Slack rawoqtkgsndvitzyfzwcdozclient_{client}_messages
Zoom transcriptsviqeppmsqvwpslpvttkkclient_{client}_raw
Zoom all meetingsviqeppmsqvwpslpvttkkzoom_meeting_recording_files

Step 3 — Execute SQL Query

Use the user-supabase MCP’s execute_sql tool with the appropriate project_id:

  • For Slack context: project_id: "oqtkgsndvitzyfzwcdoz"
  • For Zoom context: project_id: "viqeppmsqvwpslpvttkk"

SQL Query Patterns

Slack Context Queries

Get recent aggregated Slack context for a client:

SELECT period, channel, content, message_count 
FROM {client}_slack_content_blocks 
ORDER BY period DESC 
LIMIT 10;

Get Slack messages in a date range:

SELECT ts, real_name, text, channel_id 
FROM client_{client}_messages 
WHERE ts >= '2025-01-01' 
ORDER BY ts DESC 
LIMIT 50;

Search Slack messages by keyword:

SELECT ts, real_name, text 
FROM client_{client}_messages 
WHERE text ILIKE '%keyword%' 
ORDER BY ts DESC 
LIMIT 20;

Zoom Context Queries

Get recent meetings for a client:

SELECT id, meeting_date, folder, summary, participants 
FROM client_{client}_raw 
ORDER BY meeting_date DESC 
LIMIT 5;

Get full transcript for a specific meeting:

SELECT meeting_date, folder, content, summary, participants 
FROM client_{client}_raw 
WHERE meeting_date = '2025-01-08';

Search meetings by topic:

SELECT id, meeting_date, folder, summary 
FROM zoom_meeting_recording_files 
WHERE summary ILIKE '%topic%' 
   OR folder ILIKE '%topic%'
ORDER BY meeting_date DESC 
LIMIT 10;

Get meetings in a date range:

SELECT meeting_date, folder, summary, participants 
FROM client_{client}_raw 
WHERE meeting_date >= '2025-01-01' 
  AND meeting_date <= '2025-01-31'
ORDER BY meeting_date DESC;

Get meeting with transcript chunks (for detailed analysis):

SELECT e.content, e.metadata, r.meeting_date, r.folder
FROM client_{client}_embeddings e
JOIN zoom_meeting_recording_files r ON e.source_record_id = r.id
WHERE r.meeting_date = '2025-01-08'
ORDER BY e.id;

Output Format

After retrieving context, format output as:

## Context Retrieved
 
### Source
- **Client**: {client_name}
- **Data Type**: {Slack/Zoom/Both}
- **Date Range**: {date_range or "All available"}
- **Records Retrieved**: {count}
 
### Slack Context
{If Slack data was requested}
 
**Period: {period}** | **Channel: {channel}**
{content}
 
---
 
### Zoom Context
{If Zoom data was requested}
 
**Meeting: {folder}** | **Date: {meeting_date}**
**Participants**: {participants}
 
**Summary**:
{summary}
 
**Full Transcript** (if requested):
{content}
 
---

Integration with Other Prompts

After retrieving context, hand off to the appropriate playbook prompt:

User RequestContext NeededNext Prompt
”Write a SOW for Eden”Zoom meetings04-prompts/sow/sow-prompts.md
”Generate PRD from last meeting”Zoom transcript04-prompts/prd/prd-prompts.md
”Create tickets from Eden standup”Zoom transcript04-prompts/tickets/linear-ticket-agent.md
”Summarize Slack activity”Slack content blocks04-prompts/meetings/
”Review project status”Both Slack + Zoom04-prompts/review/review-prompts.md

Example Workflows

Example 1: SOW Generation

User: “Write a SOW for Eden based on our last 3 meetings”

Agent execution:

  1. Identifies client: eden
  2. Identifies data type: Zoom transcripts
  3. Executes:
SELECT meeting_date, folder, summary, content, participants 
FROM client_eden_raw 
ORDER BY meeting_date DESC 
LIMIT 3;
  1. Formats context output
  2. Passes to 04-prompts/sow/sow-prompts.md
  3. Generates SOW using template + meeting context

Example 2: Slack Summary

User: “What have we been discussing with Urban Stems this month?”

Agent execution:

  1. Identifies client: urbanstems
  2. Identifies data type: Slack messages
  3. Executes:
SELECT period, channel, content, message_count 
FROM urbanstems_slack_content_blocks 
WHERE period >= '2025-01-01'
ORDER BY period DESC;
  1. Returns formatted summary of discussions

Example 3: Combined Context

User: “I need full context on the Hedra project for a status update”

Agent execution:

  1. Identifies client: hedra
  2. Identifies data type: Both
  3. Executes Slack query on oqtkgsndvitzyfzwcdoz:
SELECT period, channel, content 
FROM hedra_slack_content_blocks 
ORDER BY period DESC LIMIT 5;
  1. Executes Zoom query on viqeppmsqvwpslpvttkk:
SELECT meeting_date, folder, summary, participants 
FROM client_hedra_raw 
ORDER BY meeting_date DESC LIMIT 5;
  1. Combines and formats output

Internal Team Context (Slack project)

For internal team context (e.g. “what did AI team say about X”), use the same user-supabase MCP with project_id: "oqtkgsndvitzyfzwcdoz" (Slack project) and query internal tables such as internal_ai_team_messages, internal_operations_messages, internal_marketing_messages, internal_sales_messages, or internal_project_management_messages.

Example:

SELECT ts, real_name, text 
FROM internal_ai_team_messages 
WHERE text ILIKE '%topic%' 
ORDER BY ts DESC 
LIMIT 20;

Error Handling

If the Slack project is not visible (e.g. list_projects doesn’t include it or queries fail with permission errors), do not stop. Run Slack MCP fallback immediately for Slack context retrieval, then note that Supabase access appears limited and reference setup doc supabase-query-access.md for remediation.

If a query returns no results:

  1. Verify client name spelling and try alternatives (e.g., urbanstems vs urban stems)
  2. Check if the table exists for that client
  3. Expand the date range if filtering by date
  4. Report: “No {data_type} found for {client} in the specified range. Would you like to try a different date range or data source?”

If a Slack query fails:

  1. Report the error message briefly
  2. Run Slack MCP fallback immediately (same workflow)
  3. Suggest checking the schema reference (04-prompts/supabase/schema-reference.md) and Supabase access setup if needed

If a Zoom query fails:

  1. Report the error message
  2. Suggest checking the schema reference: 04-prompts/supabase/schema-reference.md
  3. Offer to try an alternative query
