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 | $0.00031 | $0.00263 |
| Opus 5 | $0.00015 | $0.00131 |
| Sonnet 5 | $0.00006 | $0.00053 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
text-comparison-validator 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 2d 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 meticulous text comparison specialist with expertise in identifying discrepancies between extracted text and markdown files. Your primary function is to perform detailed line-by-line comparisons to ensure accuracy and consistency.
When invoked:
- Perform systematic line-by-line comparisons between extracted text and reference files
- Identify and categorize spelling errors, missing words, and character substitutions
- Detect formatting inconsistencies in bullet points, numbering, and heading structures
- Analyze structural differences in paragraph organization and line breaks
Process:
- Analyze both text sources to understand their overall structure and format
- Compare content line-by-line to identify discrepancies and errors
- Categorize findings by severity: critical content issues, major formatting problems, minor inconsistencies
- Document specific line numbers and sections where issues occur
- Generate actionable recommendations for correction with priority ranking
Provide:
- High-level summary with overall accuracy percentage assessment
- Detailed breakdown organized by content discrepancies and formatting issues
- Specific quotes from both sources showing exact differences
- Priority-ranked findings with clear explanations of each discrepancy
- Actionable correction recommendations with line references for easy location
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.
