Supabase Automation V2

Supabase Automation via Rube MCP

Overview

This public intake copy packages plugins/antigravity-awesome-skills/skills/supabase-automation from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

Supabase Automation via Rube MCP Automate Supabase operations including database queries, table schema inspection, SQL execution, project and organization management, storage buckets, edge functions, and service health monitoring through Composio's Supabase toolkit.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Prerequisites, Common Patterns, Known Pitfalls, Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• This skill is applicable to execute the workflow or actions described in the overview.
• Use when the request clearly matches the imported source intent: Automate Supabase database queries, table management, project administration, storage, edge functions, and SQL execution via Rube MCP (Composio). Always search tools first for current schemas.
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.
• Use when copied upstream references, examples, or scripts materially improve the answer.
• Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Verify Rube MCP is available by confirming RUBESEARCHTOOLS responds
2. Call RUBEMANAGECONNECTIONS with toolkit supabase
3. If connection is not ACTIVE, follow the returned auth link to complete Supabase authentication
4. Confirm connection status shows ACTIVE before running any workflows
5. SUPABASELISTALLPROJECTS - List projects to find the target projectref [Prerequisite]
6. SUPABASELISTTABLES - List all tables and views in the database [Prerequisite]
7. SUPABASEGETTABLE_SCHEMAS - Get detailed column types, constraints, and relationships [Prerequisite for writes]

Imported: Core Workflows

1. Query and Manage Database Tables

When to use: User wants to read data from tables, inspect schemas, or perform CRUD operations

Tool sequence:

1. SUPABASE_LIST_ALL_PROJECTS - List projects to find the target project_ref [Prerequisite]
2. SUPABASE_LIST_TABLES - List all tables and views in the database [Prerequisite]
3. SUPABASE_GET_TABLE_SCHEMAS - Get detailed column types, constraints, and relationships [Prerequisite for writes]
4. SUPABASE_SELECT_FROM_TABLE - Query rows with filtering, sorting, and pagination [Required for reads]
5. SUPABASE_BETA_RUN_SQL_QUERY - Execute arbitrary SQL for complex queries, inserts, updates, or deletes [Required for writes]

Key parameters for SELECT_FROM_TABLE:

• project_ref: 20-character lowercase project reference
• table: Table or view name to query
• select: Comma-separated column list (supports nested selections and JSON paths like profile->avatar_url)
• filters: Array of filter objects with column, operator, value
• order: Sort expression like created_at.desc
• limit: Max rows to return (minimum 1)
• offset: Rows to skip for pagination

PostgREST filter operators:

• eq, neq: Equal / not equal
• gt, gte, lt, lte: Comparison operators
• like, ilike: Pattern matching (case-sensitive / insensitive)
• is: IS check (for null, true, false)
• in: In a list of values
• cs, cd: Contains / contained by (arrays)
• fts, plfts, phfts, wfts: Full-text search variants

Key parameters for RUN_SQL_QUERY:

• ref: Project reference (20 lowercase letters, pattern ^[a-z]{20}$)
• query: Valid PostgreSQL SQL statement
• read_only: Boolean to force read-only transaction (safer for SELECTs)

Pitfalls:

• project_ref must be exactly 20 lowercase letters (a-z only, no numbers or hyphens)
• SELECT_FROM_TABLE is read-only; use RUN_SQL_QUERY for INSERT, UPDATE, DELETE operations
• For PostgreSQL array columns (text[], integer[]), use ARRAY['item1', 'item2'] or '{"item1", "item2"}' syntax, NOT JSON array syntax '["item1", "item2"]'
• SQL identifiers that are case-sensitive must be double-quoted in queries
• Complex DDL operations may timeout (~60 second limit); break into smaller queries
• ERROR 42P01 "relation does not exist" usually means unquoted case-sensitive identifiers
• ERROR 42883 "function does not exist" means you are calling non-standard helpers; prefer information_schema queries

2. Manage Projects and Organizations

When to use: User wants to list projects, inspect configurations, or manage organizations

Tool sequence:

1. SUPABASE_LIST_ALL_ORGANIZATIONS - List all organizations (IDs and names) [Required]
2. SUPABASE_GETS_INFORMATION_ABOUT_THE_ORGANIZATION - Get detailed org info by slug [Optional]
3. SUPABASE_LIST_MEMBERS_OF_AN_ORGANIZATION - List org members with roles and MFA status [Optional]
4. SUPABASE_LIST_ALL_PROJECTS - List all projects with metadata [Required]
5. SUPABASE_GETS_PROJECT_S_POSTGRES_CONFIG - Get database configuration [Optional]
6. SUPABASE_GETS_PROJECT_S_AUTH_CONFIG - Get authentication configuration [Optional]
7. SUPABASE_GET_PROJECT_API_KEYS - Get API keys (sensitive -- handle carefully) [Optional]
8. SUPABASE_GETS_PROJECT_S_SERVICE_HEALTH_STATUS - Check service health [Optional]

Key parameters:

• ref: Project reference for project-specific tools
• slug: Organization slug (URL-friendly identifier) for org tools
• services: Array of services for health check: auth, db, db_postgres_user, pg_bouncer, pooler, realtime, rest, storage

Pitfalls:

• LIST_ALL_ORGANIZATIONS returns both id and slug; LIST_MEMBERS_OF_AN_ORGANIZATION expects slug, not id
• GET_PROJECT_API_KEYS returns live secrets -- NEVER log, display, or persist full key values
• GETS_PROJECT_S_SERVICE_HEALTH_STATUS requires a non-empty services array; empty array causes invalid_request error
• Config tools may return 401/403 if token lacks required scope; handle gracefully rather than failing the whole workflow

3. Inspect Database Schema

When to use: User wants to understand table structure, columns, constraints, or generate types

Tool sequence:

1. SUPABASE_LIST_ALL_PROJECTS - Find the target project [Prerequisite]
2. SUPABASE_LIST_TABLES - Enumerate all tables and views with metadata [Required]
3. SUPABASE_GET_TABLE_SCHEMAS - Get detailed schema for specific tables [Required]
4. SUPABASE_GENERATE_TYPE_SCRIPT_TYPES - Generate TypeScript types from schema [Optional]

Key parameters for LIST_TABLES:

• project_ref: Project reference
• schemas: Array of schema names to search (e.g., ["public"]); omit for all non-system schemas
• include_views: Include views alongside tables (default true)
• include_metadata: Include row count estimates and sizes (default true)
• include_system_schemas: Include pg_catalog, information_schema, etc. (default false)

Key parameters for GET_TABLE_SCHEMAS:

• project_ref: Project reference
• table_names: Array of table names (max 20 per request); supports schema prefix like public.users, auth.users
• include_relationships: Include foreign key info (default true)
• include_indexes: Include index info (default true)
• exclude_null_values: Cleaner output by hiding null fields (default true)

Key parameters for GENERATE_TYPE_SCRIPT_TYPES:

• ref: Project reference
• included_schemas: Comma-separated schema names (default "public")

Pitfalls:

• Table names without schema prefix assume public schema
• row_count and size_bytes from LIST_TABLES may be null for views or recently created tables; treat as unknown, not zero
• GET_TABLE_SCHEMAS has a max of 20 tables per request; batch if needed
• TypeScript types include all tables in specified schemas; cannot filter individual tables

4. Manage Edge Functions

When to use: User wants to list, inspect, or work with Supabase Edge Functions

Tool sequence:

1. SUPABASE_LIST_ALL_PROJECTS - Find the project reference [Prerequisite]
2. SUPABASE_LIST_ALL_FUNCTIONS - List all edge functions with metadata [Required]
3. SUPABASE_RETRIEVE_A_FUNCTION - Get detailed info for a specific function [Optional]

Key parameters:

• ref: Project reference
• Function slug for RETRIEVE_A_FUNCTION

Pitfalls:

• LIST_ALL_FUNCTIONS returns metadata only, not function code or logs
• created_at and updated_at may be epoch milliseconds; convert to human-readable timestamps
• These tools cannot create or deploy edge functions; they are read-only inspection tools
• Permission errors may occur without org/project admin rights

5. Manage Storage Buckets

When to use: User wants to list storage buckets or manage file storage

Tool sequence:

1. SUPABASE_LIST_ALL_PROJECTS - Find the project reference [Prerequisite]
2. SUPABASE_LISTS_ALL_BUCKETS - List all storage buckets [Required]

Key parameters:

• ref: Project reference

Pitfalls:

• LISTS_ALL_BUCKETS returns bucket list only, not bucket contents or access policies
• For file uploads, SUPABASE_RESUMABLE_UPLOAD_SIGN_OPTIONS_WITH_ID handles CORS preflight for TUS resumable uploads only
• Direct file operations may require using proxy_execute with the Supabase storage API

Imported: Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Supabase connection via RUBE_MANAGE_CONNECTIONS with toolkit supabase
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Examples

Example 1: Ask for the upstream workflow directly

Use @supabase-automation-v2 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @supabase-automation-v2 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @supabase-automation-v2 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @supabase-automation-v2 using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
• Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
• Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
• Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
• Treat generated examples as scaffolding; adapt them to the concrete task before execution.
• Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills/skills/supabase-automation, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Reference Notes

Imported: Quick Reference

Imported: Common Patterns

ID Resolution

• Project reference: SUPABASE_LIST_ALL_PROJECTS -- extract ref field (20 lowercase letters)
• Organization slug: SUPABASE_LIST_ALL_ORGANIZATIONS -- use slug (not id) for downstream org tools
• Table names: SUPABASE_LIST_TABLES -- enumerate available tables before querying
• Schema discovery: SUPABASE_GET_TABLE_SCHEMAS -- inspect columns and constraints before writes

Pagination

• SUPABASE_SELECT_FROM_TABLE: Uses offset + limit pagination. Increment offset by limit until fewer rows than limit are returned.
• SUPABASE_LIST_ALL_PROJECTS: May paginate for large accounts; follow cursors/pages until exhausted.
• SUPABASE_LIST_TABLES: May paginate for large databases.

SQL Best Practices

• Always use SUPABASE_GET_TABLE_SCHEMAS or SUPABASE_LIST_TABLES before writing SQL
• Use read_only: true for SELECT queries to prevent accidental mutations
• Quote case-sensitive identifiers: SELECT * FROM "MyTable" not SELECT * FROM MyTable
• Use PostgreSQL array syntax for array columns: ARRAY['a', 'b'] not ['a', 'b']
• Break complex DDL into smaller statements to avoid timeouts

Imported: Known Pitfalls

ID Formats

• Project references are exactly 20 lowercase letters (a-z): pattern ^[a-z]{20}$
• Organization identifiers come as both id (UUID) and slug (URL-friendly string); tools vary in which they accept
• LIST_MEMBERS_OF_AN_ORGANIZATION requires slug, not id

SQL Execution

• BETA_RUN_SQL_QUERY has ~60 second timeout for complex operations
• PostgreSQL array syntax required: ARRAY['item'] or '{"item"}', NOT JSON syntax '["item"]'
• Case-sensitive identifiers must be double-quoted in SQL
• ERROR 42P01: relation does not exist (check quoting and schema prefix)
• ERROR 42883: function does not exist (use information_schema instead of custom helpers)

Sensitive Data

• GET_PROJECT_API_KEYS returns service-role keys -- NEVER expose full values
• Auth config tools exclude secrets but may still contain sensitive configuration
• Always mask or truncate API keys in output

Schema Metadata

• row_count and size_bytes from LIST_TABLES can be null; do not treat as zero
• System schemas are excluded by default; set include_system_schemas: true to see them
• Views appear alongside tables unless include_views: false

Rate Limits and Permissions

• Enrichment tools (API keys, configs) may return 401/403 without proper scopes; skip gracefully
• Large table listings may require pagination
• GETS_PROJECT_S_SERVICE_HEALTH_STATUS fails with empty services array -- always specify at least one

Imported: Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
