## What it does

The command accepts a table name, a SQL query, or the `--export` and `--inspect` flags. It can inspect table structures, relationships, indexes, and constraints, then analyze data distribution, trends, and anomalies. It also looks for a few local SQL files and `types` or `models` directories to add project context.

Queries run through a connected Supabase MCP with read-only access. The workflow includes query validation, result limits, execution-plan analysis, and optimization suggestions. Its output can include data insights, exported files, visualizations, summary reports, and performance recommendations.

Without a connected Supabase MCP, the command cannot read the database: its Supabase access is provided through MCP and is restricted to read-only operations.

## Requirements
- Works with: Supabase

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --command database/supabase-data-explorer
```

2. **Manually: put the files in place**
- File: `.claude/commands/supabase-data-explorer.md` — Call it with /supabase-data-explorer. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/supabase-data-explorer.md` — Call it with /prompts:supabase-data-explorer. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/supabase-data-explorer.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/supabase-data-explorer.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/davila7/claude-code-templates/tree/HEAD/cli-tool/components/commands/database/supabase-data-explorer.md

## When to use it
- inspect a Supabase table structure
- run a read-only SQL query
- trace relationships, indexes, and constraints
- export database data for analysis
- review a query execution plan

## Example prompts
- Inspect the `[table-name]` table with `/supabase-data-explorer [table-name]`.
- Run a read-only query and explain the results with `/supabase-data-explorer --query [sql]`.
- Inspect the database and prepare an export with `/supabase-data-explorer --inspect --export`.

# Supabase Data Explorer

Explore and analyze Supabase database with intelligent querying and data insights: **$ARGUMENTS**

## Current Data Context

- Supabase MCP: Connected with read-only access for safe data exploration
- Target table: Analysis of $ARGUMENTS for data exploration scope
- Local queries: !`find . -name "*.sql" | head -5` existing SQL files for reference
- Data models: !`find . -name "types" -o -name "models" -type d | head -3` application data structures

## Task

Execute comprehensive database exploration with intelligent analysis and insights:

**Exploration Focus**: Use $ARGUMENTS to specify table inspection, SQL query execution, data export, or comprehensive database inspection

**Data Exploration Framework**:
1. **Database Discovery** - Explore table structures, analyze relationships, identify data patterns, assess data quality metrics
2. **Intelligent Querying** - Execute read-only queries via MCP, optimize query performance, provide result analysis, suggest query improvements
3. **Data Analysis** - Generate data insights, identify trends and anomalies, calculate statistical summaries, analyze data distribution
4. **Schema Inspection** - Examine table schemas, analyze foreign key relationships, assess index effectiveness, review constraint validations
5. **Export & Visualization** - Export data in multiple formats, create data visualizations, generate summary reports, optimize data presentation
6. **Performance Analysis** - Analyze query execution plans, identify performance bottlenecks, suggest optimization strategies, monitor resource usage

**Advanced Features**: Interactive data exploration, automated insight generation, data quality assessment, relationship mapping, trend analysis.

**Safety Features**: Read-only operations, query validation, result limiting, performance monitoring, error handling.

**Output**: Comprehensive data exploration with insights, optimized queries, export files, and performance recommendations.
