• docs_list_sectionsList available documentation sections and their page counts
• cli_lookup_commandLook up Avalanche CLI, Platform CLI, and tmpnet command guidance in the docs. Returns cited command references and task docs.
• rpc_lookup_methodLook up Avalanche RPC methods and API guides across C-Chain, P-Chain, X-Chain, Subnet-EVM, and node RPC docs.
• acp_lookupLook up Avalanche Community Proposals (ACPs) by number, title, or topic. When a number is provided the structured ACP record is returned (title, status, track, authors, cross-references).
• acp_listList Avalanche Community Proposals with structured fields, optionally filtered by status (Activated, Implementable, Proposed, Stale, Withdrawn) or track (Standards, Best Practices, Meta, Subnet).
