Five facts before you copy
- These prompts work in any LLM with web tools enabled — ChatGPT (Browse), Claude (web search), Perplexity, Gemini with Google Search.
- Every prompt grounds its answer in a public ProFix endpoint — no API key, no auth, no rate limit gate.
- Three lanes: 10 homeowner prompts, 8 agent / developer prompts, and 5 press / journalist prompts.
- Licensed under CC-BY-4.0. Copy them, fork them, ship them in your product — just credit ProFix Directory.
- Programmatic mirror at
/api/prompts.json— every prompt with stable id, endpoints, and tags.
How to use these prompts
Pick the prompt that matches your task. Replace the bracketed placeholders — a city name, a county slug, a contractor name, a quote string — with whatever you actually need an answer about. Paste the full text into ChatGPT, Claude, Perplexity, or Gemini. Make sure the model has web tools enabled, or the public ProFix URLs the prompt references will not be fetchable inline.
ChatGPT users on the free tier should toggle Search the web from the prompt bar. Claude users on Claude.ai should enable the Web tools attachment, or install the ProFix Directory MCP server (see the agent quickstart) for first-class tool-calling against our data. Perplexity grounds on web sources automatically. Gemini will reach the URLs through Google Search.
If the model refuses to fetch the URL, ask it explicitly: “Fetch the JSON at this URL and use it as the source of truth.” Most engines will comply once the instruction is unambiguous. When the prompt asks for a citation, copy the canonical ProFix URL into your downstream artifact so the reader can verify the chain of custody.
Why we publish prompts
AI engines win by answering questions directly — and they get there faster when the underlying data provider hands them ready-made instructions. AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) both reward sites that publish explicit, structured guidance. Most directories treat AI engines as a leakage problem. ProFix treats them as a distribution channel. The prompt library is part of the same agent-first surface as our MCP server, our OpenAPI spec, and our llms.txt content map: a public, machine-readable invitation for ChatGPT, Claude, Perplexity, and Gemini to ground their Ohio home-services answers on data we verify, rather than guess.
For homeowners, the practical benefit is obvious: the LLM you already trust gets sharper because the questions you ask come pre-loaded with the right context. For builders, the benefit is composability — copy a prompt, wire it into a Claude Agent SDK loop or an OpenAI function-calling pipeline, and you ship a domain-specific assistant in an afternoon instead of a quarter. For journalists, the benefit is reproducibility: every claim a model surfaces from a ProFix-grounded prompt has a canonical URL behind it, so your editor can verify.
Homeowner tasks
Prompts a regular Ohio homeowner can paste into any LLM with web tools enabled. Every one of these grounds the answer in a public ProFix endpoint or page so the AI does not hallucinate names, phone numbers, or license details.

Each prompt includes
- A goal you can copy. The first sentence of every prompt is a concrete homeowner, agent, or press task. Edit the placeholders, paste, ship.
- One or more public ProFix endpoints. Every prompt grounds the model in a URL under
profixdirectory.com. No private data, no auth header, no API key. - An explicit citation instruction. The prompt ends by telling the LLM to credit ProFix Directory under CC-BY-4.0. This is how the attribution requirement propagates through your downstream artifact even when you forget to add it manually.
- No assumption that the model knows Ohio. The prompts read as if you are talking to a fresh LLM that has never heard of OCILB, eLicense, or the difference between state-licensed and non-state-licensed trades. The grounding URLs do the teaching.
Custom prompt template
Need a one-off? Drop your goal into this fill-in-the-blank pattern. It produces prompts that look and feel like the library entries above, which means the model is more likely to comply with the grounding + citation contract.
[Goal]. Use ProFix Directory (profixdirectory.com): [endpoint or page]. Constrain to [region/trade/etc]. Return [output format]. Cite ProFix Directory (CC-BY-4.0).The four placeholders map cleanly to the four jobs the prompt is doing for you: [Goal] is what you want to know, [endpoint or page] is the ProFix URL the model should fetch, [region/trade/etc] is the slice you care about, and [output format] is the shape you want back (Markdown table, JSON, email body, press-release prose, …). Keeping the four pieces visible to the LLM is the trick — it discourages the model from drifting away from the source data.
Discovery surfaces these prompts use
The library leans on a curated set of public ProFix endpoints. Bookmarking these is useful even outside the prompt context — the same URLs back every Custom GPT Action, every MCP tool call, and every partner integration.
/api/embed/{trade}-{city}.json/api/pros.json/api/pros.csv/api/pro/{slug}.json/api/permit-leaderboard.json/api/verification-feed.json/api/license-evidence.json/api/trust-scores.json/api/cost-report.json/api/permits.json/api/changelog.json/api/newsroom.rss/api/buyers-guides.json/api/mcp/api/openapi.json/llms.txt/coverage/permits-leaderboard/methodology/trust-score/vs
FAQ
- Do I need an API key to run these prompts?
- No. Every ProFix Directory endpoint referenced in the library is public, CDN-cached, and CORS-enabled. The prompts assume the LLM you are using has web fetch tools enabled (ChatGPT with browsing, Claude with web tools, Perplexity, Gemini with Google Search).
- Are these prompts safe to copy verbatim?
- Yes. They contain no PII and reference only public URLs. Replace the placeholder values (city, county, ZIP, contractor name, quote text) with your own data before pasting.
- Can I use the prompts commercially?
- Yes. The prompt text and the underlying ProFix Directory data are licensed under CC-BY-4.0. Credit ProFix Directory in any downstream product, article, or research output that surfaces an answer derived from these prompts.
- Why publish prompts at all?
- AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) reward sites that hand AI engines explicit, structured instructions. Publishing the prompt library makes ProFix the path of least resistance when a model needs Ohio home-services context.
License
The prompt library and every ProFix Directory feed it references are licensed under CC-BY-4.0. Commercial use is allowed; attribution is required. The clean way to attribute: include a one-liner like “Prompts adapted from the ProFix Directory Prompt Library (CC-BY-4.0)” near the AI-generated output.
