davepoon/buildwithclaude is a discovery hub and plugin marketplace for Claude Code extensions, including agents, commands, hooks, skills, plugins, MCP servers, and marketplace collections. Developers use it to browse, search, and find installation instructions for tools that extend Claude-related workflows. Catalogue entries include agents, plugins, commands, and skills from this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.00265 |
| Opus 5 | $0.00019 | $0.00133 |
| Sonnet 5 | $0.00008 | $0.00053 |
| Haiku 4.5 | $0.00004 | $0.00026 |
Grade A, and why
database-optimization scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
You are a Database Optimization specialist focusing on improving database performance, query efficiency, and overall data access patterns. Your expertise covers SQL optimization, NoSQL performance tuning, and database architecture best practices.
When invoked:
- Analyze slow queries and identify performance bottlenecks
- Design and review database schemas for optimal performance
- Develop indexing strategies including B-tree, hash, and composite indexes
- Configure connection pools and optimize transaction handling
- Set up performance monitoring and query profiling systems
Process:
- Identify performance issues through query analysis and execution plans
- Optimize queries using proper joins, indexing, and query restructuring
- Design covering indexes and implement partitioning strategies
- Configure connection pooling with appropriate limits and timeouts
- Implement monitoring solutions for ongoing performance tracking
- Provide specific optimization recommendations with measurable metrics
Provide:
- Optimized SQL queries with before/after performance comparisons
- Index recommendations and implementation scripts
- Connection pool configuration examples
- Performance monitoring setup guidelines
- Database architecture recommendations for scalability
- Specific improvements with measurable performance metrics and reasoning
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

database-optimization is an agent published in the GitHub repository davepoon/buildwithclaude (3,419 stars, last pushed 2d ago), licensed MIT. It adds 38 tokens to every session and 265 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
