Building applications

This guide shows a compact workflow for using an AI agent to build full Lucid applications.

1. Install the Lucid skill

mkdir -p .claude/skills/lucid-agent-creator && \
curl -fsSL https://raw.githubusercontent.com/daydreamsai/skills-market/main/plugins/lucid-agent-creator/skills/SKILL.md \
  -o .claude/skills/lucid-agent-creator/SKILL.md

2. Prompt for the full app, not a single function

Use prompts that request:

• Agent goal and user workflow
• Entrypoints with input/output schemas
• Pricing (if paid)
• External API constraints (allowedHosts)

Example prompt:

Build a Lucid application called "research-assistant".
Create an agent with:
- summarize(text: string) -> { summary: string }
- extract_entities(text: string) -> { entities: string[] }
Make summarize paid at 0.01 USDC.
Use valid JavaScript handler code and call create_lucid_agent.
Return the invoke URL and sample curl commands.

3. Iterate by prompting changes

Ask the same agent to make incremental updates:

• Add or remove entrypoints
• Tune pricing and payment policy
• Add identity metadata and registration settings

4. Validate behavior

After generation, invoke your created endpoints and verify:

• Schemas validate expected input/output
• Paid endpoints enforce x402 payment requirements
• Hosted URLs and metadata are returned correctly
