Use this index from your agent

Give any AI agent one file and it can pick the best prompt from this index for each task you hand it. The index is static: no server, no account, no key.

How it works

1. The agent reads the router file and classifies your task by category, type and technique.
2. It fetches one small JSON shard for that category.
3. It ranks the entries, fetches the full text of the best one, fills the blanks with your material and does the work.
4. It tells you which prompt it used, with a link you can reuse.

Copy-paste setup

Option 1. One line in your agent's instructions (works with any agent that can fetch a URL):

For any task I give you, first read https://jackgross-five.vercel.app/router.md and follow it: pick the best prompt from the index, fetch it, fill it with my material, and tell me which prompt id you used.

Option 2. One-shot, paste into a chat with an agent that can browse:

Read https://jackgross-five.vercel.app/router.md. Then, for this task, route to the best prompt in the index and use it: [DESCRIBE YOUR TASK]

Option 3. Plain scripts and tools, no agent needed:

curl -s https://jackgross-five.vercel.app/api/prompts/category/coding.json | jq '.entries[] | select(.type=="debug") | {id,title,url}'
curl -s https://jackgross-five.vercel.app/api/prompts/p/c22.json | jq -r .text

One router, every section

Agents are routed by task and phase, so they never read a whole collection. The start file is under 2 KB and points to small phase files.

• Prompts: select, fill, verify
• MCP servers: discover, evaluate, install, secure (43,992 servers in category shards of 800 entries, official and recently updated first)
• AI Extensions digest: latest, lookup, verify
• UX templates: choose, adapt, build, review (224 templates)
• Diary posts: browse, lookup, cite

• /router.md - Start file
• /router/index.json - Machine-readable map
• /mcp-index/index.json - MCP server index
• /extensions-index/index.json - Extensions index

Endpoints

• /router.md - Router instructions (Markdown)
• /prompt-index/index.json - Taxonomy and compact index (JSON)
• /prompt-index/category/coding.json - Per-category shard
• /prompt-index/p/c22.json - Full prompt
• /prompt-index/t/60.json - Template with 14 technique variants

Good to know

• All files are static and send CORS headers, so browser agents can read them.
• The index lists the hand-written, hot and design prompts and the 168 task templates. The 50,400 composed prompts on the site are variants of those templates by subject, technique, format and model wrapper.
• The agent should only use ids and text it fetched. Your material is never sent to this site.
• Design prompts come from open-licensed collections and keep their attribution.
