Building HydrAIDE data models and applications with the Go SDK (`hydraidego`). Sanctuary/Realm/Swamp addressing, Profile vs Catalog patterns, struct tags, msgpack encoding, server-side filters (AND/OR, vector, geo, nested-slice, phrase, IN), atomic increments, distributed locks, real-time subscriptions, structural patches, indexing/pagination, common pitfalls. Use when designing, implementing, or debugging Go application code against HydrAIDE. For other languages, see the corresponding `hydraide<lang>` skill. For server operations, see the `hydraidectl` skill.
Conceptual and educational explanations of HydrAIDE — how the engine works internally, why it is designed the way it is, what Swamp lifecycle, addressing, query engine, msgpack patch, subscriptions, locking, and the storage engine actually do under the hood. Use when the user asks "how does X work", "why does HydrAIDE do Y", "explain the architecture of Z", or wants to understand concepts (not write implementation code). For Go SDK code, use the `hydraidego` skill. For server operations, use the `hydraidectl` skill.
Ad-hoc data operation CLIs against a HydrAIDE instance. Migration between swamps, restore from export, bulk import, bulk delete, bulk update, orphan cleanup, cross-environment data sync, reconciliation. Use when the user asks Claude to write a one-shot Go program that reads, transforms, writes, or removes data in HydrAIDE outside of long-lived application code. For long-lived application logic, use `hydraidego`. For binary-level server operations (backup the instance, upgrade the binary, restart, observe), use `hydraidectl`.
Installing, upgrading, and bootstrapping HydrAIDE. Server install on Linux as a systemd service, Docker install for dev or production, Go SDK install in your application, server and SDK upgrades, V1 to V2 storage migration, filesystem and hardware guidance, and troubleshooting common install errors. Use when starting fresh with HydrAIDE, picking an install method, upgrading the server or the SDK, planning a storage migration, or hitting install or setup errors. For day-to-day server operations after install, use the `hydraidectl` skill. For Go application code that uses the SDK, use the `hydraidego` skill. For conceptual questions about how the engine works, use the `hydraide` skill.
Operating HydrAIDE instances with the hydraidectl CLI — install, start/stop/restart, upgrade, backup/restore, migrate (V1→V2), inspect, observe, compact, explore, destroy, certs. Use when installing, deploying, upgrading, migrating, backing up, debugging, or otherwise operating a HydrAIDE server instance. For Go SDK usage and data modelling, use the `hydraidego` skill instead.
