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.

Domain references

Audience	Reference
All — shared architecture (read first)	references/shared.md
Token accounts (SPL-compatible, 165 bytes)	references/token-accounts.md
Mint accounts (borsh-deserialized, metadata)	references/mint-accounts.md
Compressible PDAs (per-program, discriminator check)	references/pdas.md

Account type decision

Streaming...	Account type	Key difference
SPL-compatible token balances	Token accounts	PodAccount parsing, 165-byte layout
Mint supply, metadata, authorities	Mint accounts	Mint::deserialize, borsh layout
Your program's PDA state	Compressible PDAs	8-byte discriminator check, per-program filter

Security

This skill does not pull, store, or transmit external secrets. It provides code patterns, documentation references, and development guidance only.

• No credentials consumed. The skill requires no API keys, private keys, or signing secrets. env: [] is declared explicitly.
• User-provided configuration. RPC endpoints, wallet keypairs, and authentication tokens (Privy, wallet adapters) are configured in the user's own application code — the skill only demonstrates how to use them.
• API keys. Reference code uses HELIUS_API_KEY as a placeholder. For production, set your RPC provider key as an environment variable.
• Subagent scope. This skill may spawn read-only subagents that use Read, Glob, and Grep to search the local repository. Restrict the working directory to your project.
• Install source. npx skills add Lightprotocol/skills installs from the public GitHub repository (Lightprotocol/skills). Verify the source before running.
• Audited protocol. Light Protocol smart contracts are independently audited. Reports are published at github.com/Lightprotocol/light-protocol/tree/main/audits.
