data-streaming

通过 Laserstream gRPC 流式传输 Light Protocol 账户状态。支持代币账户、铸造账户，以及可压缩的 PDA，并提供热/冷生命周期追踪功能。适用于构建自定义数据管道、聚合器或索引器时使用。

Data Streaming

Stream Light Protocol account state transitions via Laserstream gRPC.

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

When NOT to use

For simple account lookups, call get_account_interface from light-client. It races hot and cold lookups automatically.

This skill is for continuous data pipelines: aggregators, market makers, and indexers that need real-time state change notifications rather than point queries.
