Short, honest answers to the things Product Hunt reviewers and TAAFT visitors tend to ask in the first thirty seconds.
AgentLevier is a marketplace of $0.99 skill packs for AI agents. Each pack is a tested, opinionated JSON drop-in — a system prompt, a set of instructions, a workflow, and the reference data that goes with it — designed to give an agent the same unfair starting line a senior builder would write by hand.
You browse, you pay, you copy the JSON into your agent's system prompt. No subscriptions, no accounts to create, no usage meters.
A skill pack is a structured JSON object with one job: teach an agent to do a specific domain task well. The fields look like this:
version · skill_name · compatibility · system_prompt · instructions[] · workflow_steps[] · reference_data{}
A typical pack is 2–8 KB of raw JSON, which works out to roughly 800–2,500 tokens once it's injected into your system prompt. That fits comfortably inside every modern context window without displacing much else.
The deliverable is a JSON blob you receive at POST /api/purchase (and on the /success page). Drop it straight into any LLM that takes a system prompt — GPT-4, Claude, Mistral, anything that reads JSON.
Three audiences, in roughly that order:
(a) Solo founders building one agent. You've got a product, you've got a system prompt, and the next six prompts you need to write are all the same shape. A $0.99 pack outpaces two hours of fiddling every time.
(b) AI agents and automation scripts. The catalog is exposed at GET /api/courses and purchases go through POST /api/purchase. An agent can browse, decide, pay, and ingest a pack in a single round trip — no human in the loop.
(c) Creators who want a tested baseline to remix. Each pack ships as plain JSON. Read it, fork it, swap the prompt for your voice, and you've shaved a week off the bottom of your project.
Because that's below the threshold where a buyer needs a sales call, a free trial, or a refund window to feel safe trying it. Cheaper than a coffee. Lower than the cost of writing the same prompt twice.
There's no subscription, no account, no seat licence. You pay once, you own the JSON. Every dollar you spend buys you back roughly the hour it would've taken to rewrite that system prompt from scratch.
The frame we're optimising for is described in more depth on the about page.
Full refund if the pack doesn't work in your stack. Email agentlevier@polsia.app with the slug and a one-line note about what broke; we reply and refund the same week.
Because a skill pack is a JSON blob, we can't undo your copy of it, but we can undo your charge. There is no fine print, no win-back flow, no support tier you have to climb. If it didn't pay for itself, you get your dollar back.
