We split this skill into the rules it gives an agent

5 rules. 0 are common, 5 are distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 10 edited versions we read keep these.

  • 5

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

    Add CTEs where helpful

  3. Distinctive:

    Use this skill only when the task clearly matches the scope described above.

  4. Distinctive:

    Do not treat the output as a substitute for environment-specific validation, testing, or expert review.

    line 171
  5. Distinctive:

    Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

    line 172

“Common” is measured: kept by at least 6 in 10 of the 10 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

PostgreSQL Optimization Workflow

Overview

Specialized workflow for PostgreSQL database optimization including query tuning, indexing strategies, performance analysis, vacuum management, and production database administration.

When to Use This Workflow

Use this workflow when:

  • Optimizing slow PostgreSQL queries
  • Designing indexing strategies
  • Analyzing database performance
  • Tuning PostgreSQL configuration
  • Managing production databases

Workflow Phases

Phase 1: Performance Assessment

Skills to Invoke

  • database-optimizer - Database optimization
  • postgres-best-practices - PostgreSQL best practices

Actions

  1. Check database version
  2. Review configuration
  3. Analyze slow queries
  4. Check resource usage
  5. Identify bottlenecks

Copy-Paste Prompts

Use @database-optimizer to assess PostgreSQL performance

Phase 2: Query Analysis

Skills to Invoke

  • sql-optimization-patterns - SQL optimization
  • postgres-best-practices - PostgreSQL patterns

Actions

  1. Run EXPLAIN ANALYZE
  2. Identify scan types
  3. Check join strategies
  4. Analyze execution time
  5. Find optimization opportunities

Copy-Paste Prompts

Use @sql-optimization-patterns to analyze and optimize queries

Phase 3: Indexing Strategy

Skills to Invoke

  • database-design - Index design
  • postgresql - PostgreSQL indexing

Actions

  1. Identify missing indexes
  2. Create B-tree indexes
  3. Add composite indexes
  4. Consider partial indexes
  5. Review index usage

Copy-Paste Prompts

Use @database-design to design PostgreSQL indexing strategy

Phase 4: Query Optimization

Skills to Invoke

  • sql-optimization-patterns - Query tuning

Actions

  1. Rewrite inefficient queries
  2. Optimize joins
  3. Add CTEs where helpful
  4. Implement pagination
  5. Test improvements

Copy-Paste Prompts

Phase 6: Maintenance

Skills to Invoke

  • database-admin - Database maintenance
  • postgresql - PostgreSQL maintenance

Actions

  1. Schedule VACUUM
  2. Run ANALYZE
  3. Check table bloat
  4. Monitor autovacuum
  5. Review statistics

Phase 7: Monitoring

Skills to Invoke

  • grafana-dashboards - Monitoring dashboards

Actions

  1. Set up monitoring
  2. Create dashboards
  3. Configure alerts
  4. Track key metrics
  5. Review trends

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.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
