Database schema validation tools - SQL syntax checking, constraint validation, naming convention enforcement, and schema integrity verification. Use when validating database schemas, checking migrations, enforcing naming conventions, verifying constraints, or when user mentions schema validation, migration checks, database best practices, or PostgreSQL validation.

What this skill does


# Schema Validation

Comprehensive database schema validation for Supabase/PostgreSQL projects. Validates SQL syntax, naming conventions, constraints, indexes, and RLS policies before deployment.

## Instructions

### 1. Run Full Validation
```bash
cd /path/to/project
bash /home/vanman2025/Projects/ai-dev-marketplace/plugins/supabase/skills/schema-validation/scripts/full-validation.sh <schema-file-or-directory>
```

### 2. Run Individual Validations

**SQL Syntax Validation:**
```bash
bash scripts/validate-sql-syntax.sh <sql-file>
```

**Naming Convention Validation:**
```bash
bash scripts/validate-naming.sh <sql-file>
```

**Constraint Validation:**
```bash
bash scripts/validate-constraints.sh <sql-file>
```

**Index Validation:**
```bash
bash scripts/validate-indexes.sh <sql-file>
```

**RLS Policy Validation:**
```bash
bash scripts/validate-rls.sh <sql-file>
```

### 3. Generate Validation Report
The full validation script generates a detailed markdown report showing:
- Validation results for each check
- Issues found with severity levels (ERROR, WARNING, INFO)
- Recommendations for fixes
- Summary statistics

### 4. Configure Validation Rules
Customize validation rules by editing:
```bash
templates/validation-rules.json
templates/naming-conventions.json
```

## Examples

### Example 1: Validate Migration Before Deployment
```bash
# Validate a new migration file
bash scripts/full-validation.sh supabase/migrations/20250126_add_users_table.sql

# Review the generated report
cat validation-report.md
```

### Example 2: Validate Entire Schema Directory
```bash
# Validate all migration files
bash scripts/full-validation.sh supabase/migrations/

# Check for common issues
grep "ERROR" validation-report.md
```

### Example 3: CI/CD Integration
```bash
# Add to .github/workflows/validate-schema.yml
- name: Validate Database Schema
  run: |
    bash plugins/supabase/skills/schema-validation/scripts/full-validation.sh supabase/migrations/
    if grep -q "ERROR" validation-report.md; then
      exit 1
    fi
```

## Validation Checks

### SQL Syntax (validate-sql-syntax.sh)
- PostgreSQL syntax compliance
- Reserved keyword usage
- Statement termination
- Data type validity

### Naming Conventions (validate-naming.sh)
- Lowercase with underscores (snake_case)
- Plural table names
- Singular column names
- Constraint naming patterns (fk_, uq_, ck_, pk_)
- Index naming patterns (idx_, uidx_)

### Constraints (validate-constraints.sh)
- Primary key existence
- Foreign key references
- Unique constraint usage
- Check constraint validity
- NOT NULL enforcement

### Indexes (validate-indexes.sh)
- Index coverage for foreign keys
- Index coverage for RLS policy columns
- Duplicate index detection
- Index naming conventions

### RLS Policies (validate-rls.sh)
- RLS enabled on public tables
- Policy existence for CRUD operations
- Role specification (authenticated, anon)
- Performance optimization (proper indexing)

## Requirements

- PostgreSQL client tools (psql) for syntax validation
- Bash 4.0+ for script execution
- Read access to schema files
- Write access for generating reports

## Best Practices

1. **Run validation before every migration**
2. **Fix ERRORs immediately** - these will cause deployment failures
3. **Address WARNINGs** - these indicate potential issues
4. **Review INFO items** - these are suggestions for improvement
5. **Keep validation rules updated** as your schema evolves
6. **Integrate into CI/CD** to prevent invalid schemas from being deployed

jfrog

Included

Interact with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
