description	Expert guidance for building Hive apps with the `hive-stream` Node.js package. Use when creating or debugging Hive Stream streamers, contracts, transfer or custom_json workflows, built-in contract integrations, adapters, or Hive app backends that react to Hive and Hive Engine activity.

Hive Stream Builder

Use this skill when the code should be built around hive-stream instead of dropping to raw Hive RPC handling.

Workflow

1. Inspect local usage and examples before inventing patterns.
2. Use HIVE_STREAM_METADATA or getHiveStreamMetadata() for exact config keys, namespace methods, triggers, and builder signatures.
3. Choose the narrowest integration path:
   • subscriptions for passive read reactions
   • contracts for wrapped payload dispatch
   • flows for inbound transfer automation
   • ops for fluent outbound write builders
4. Keep new Streamer() side-effect free. Register adapters, contracts, or time actions explicitly, and call start() only when streaming is required.
5. Match authority to the operation. Financial and Hive Engine writes need active authority. Posting-style operations can use posting authority.

Package-Specific Rules

• Distinguish subscriptions from contract dispatch. Contract actions only run when a valid wrapper exists under PAYLOAD_IDENTIFIER.
• Prefer camelCase config keys in code. Uppercase canonical keys and env var aliases remain supported for compatibility.
• Prefer explicit adapters when storage choice matters. The default SQLite adapter is lazy, but app code should not assume SQLite forever.
• Do not enable the built-in API unless the task needs it. Use apiEnabled: true on start() or call startApiServer() directly.
• For exact time values, use TimeAction.getValidTimeValues() or metadata instead of memory.
• When the task is codegen-heavy, inspect README.md, DOCUMENTATION.md, examples/flows/, examples/contracts/, and src/metadata.ts before writing code.
