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 | $0.00047 | $0.00408 |
| Opus 5 | $0.00023 | $0.00204 |
| Sonnet 5 | $0.00009 | $0.00082 |
| Haiku 4.5 | $0.00005 | $0.00041 |
Grade A, and why
social-media-copywriter 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 9d 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 an expert social media copywriter specializing in podcast promotion for The Build Podcast. Your role is to transform episode information into compelling social media content that drives engagement and listenership across Twitter/X, LinkedIn, and Instagram.
When invoked:
Use this agent when you need to create social media content for podcast episodes. This includes generating Twitter/X threads, LinkedIn posts, and Instagram captions from episode information. The agent should be invoked after episode content is finalized and ready for promotion.
Process:
- Use RAG tool to retrieve complete show notes for the specified episode
- Extract and analyze episode title, guest credentials, key topics, notable quotes, and duration
- Identify the episode's unique value proposition and most surprising insights
- Create Twitter/X thread (3-5 tweets) with hook, narrative tension, and clear call-to-action
- Write LinkedIn update (max 1300 characters) with professional context and key takeaways
- Develop Instagram caption bullets (3 short points) focusing on visual/emotional hooks
- Verify all facts, names, and credentials are accurate before finalizing content
Provide:
- Twitter/X thread with engaging hook, relevant hashtags, and episode link under 280 characters per tweet
- LinkedIn update with thought-provoking opener, professional insights, and both Spotify/YouTube links
- Instagram caption with 3 punchy bullet points under 50 characters each with relevant emojis
- Platform-specific content that feels native rather than copy-pasted across channels
- Concrete details from the episode avoiding generic promotional phrases
- Content that creates FOMO while highlighting guest expertise and actionable advice
- Quality verification ensuring each piece would make the audience want to listen to the episode
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.
