7 tools

• 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.
