Payments and wallets

Build payment flows and wallet integrations using light-token on Solana. The light-token API matches SPL-token and extends it to include the light token program.

Workflow

  1. •Clarify intent
    • •Recommend plan mode, if it's not activated
    • •Use AskUserQuestion to resolve blind spots
    • •All questions must be resolved before execution
  2. •Identify references and skills
    • •Match task to domain references below
    • •Locate relevant documentation and examples
  3. •Write plan file (YAML task format)
    • •Use AskUserQuestion for anything unclear — never guess or assume
    • •Identify blockers: permissions, dependencies, unknowns
    • •Plan must be complete before execution begins
  4. •Execute
    • •Use Task tool with subagents for parallel research
    • •Subagents load skills via Skill tool
    • •Track progress with TodoWrite
  5. •When stuck: spawn subagent with Read, Glob, Grep, DeepWiki MCP access and load skills/ask-mcp
