## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability skill-md-stub-generator-25378a77 -d '<json body>'
```

Example prompt: Generate a skill.md stub for a Delx pack called 'Market Analysis Suite' that includes these tools: price_feed, sentiment_analyzer, and portfolio_tracker.

## When to prefer this

Choose this endpoint when you need a fast, cheap, deterministic markdown scaffold for a Delx agent skill.md file and do not want to hand-write boilerplate. Ideal for bootstrapping new agent packs programmatically. Prefer this over manual authoring or LLM-freeform generation when you need a consistent, structured stub format compatible with Delx pack conventions.

## Known failure modes

- Missing or empty title field returns validation error
- Empty or malformed tool_names array may produce incomplete scaffold
- Payment failure via x402 (insufficient USDC balance or Base network issues) blocks request
- Malformed JSON request body returns 400-level error

## How this service works

Generate a minimal skill.md body for a product cluster. Call when agents need a portable skill skeleton for a Delx pack. Returns markdown string as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

A deterministic JSON response containing a markdown string representing the minimal skill.md body, including the provided title and tool names formatted as a portable Delx skill skeleton ready for use in an agent pack.
