## Tools (as reported by the server, not verified)

- `subtensor\_search`: Search across all Subtensor pallets, events, calls, storage, constants, and errors by keyword.
- `subtensor\_lookup`: Get detailed info about a specific pallet, event, call, storage item, constant, error, SCALE type, RPC method, protocol account, or EVM precompile. Accepts URN identifiers with optional \#field.path drilling.
- `subtensor\_list`: Browse items by category: pallets, events, calls, storage, constants, errors, types, runtime APIs, RPC methods, protocol accounts, EVM precompiles, mechanisms, workflows, hyperparameters, cli\_flags, build\_features, chain\_specs, or env\_vars.
- `subtensor\_explore`: Explore relationships, version history, removed items, changelogs, and migration guides between runtime versions.
- `subtensor\_explain`: Understand Bittensor concepts, workflows, mechanisms, runtime APIs, runtime errors, extrinsic format, or get code examples.
- `subtensor\_preferences`: Get or set session preferences for language, node URL, and node type. Language affects field name casing \(TypeScript=camelCase, others=snake\_case\) and code examples.
- `subtensor\_decode`: Decode SCALE-encoded hex into labelled fields with RAO→TAO and hex→SS58 conversions applied. Omit pallet and name to identify an event or call from its two-byte \(pallet index, item index\) prefix — the usual case when you have bytes and want to know what they are.
