Functions exposed to the LLM to take actions

NameDescription
ask_fuguA

Ask Sakana Fugu (a separate orchestration LLM) for a second opinion on a HARD, SELF-CONTAINED problem, or to cross-check your own reasoning with a different model. Good for: a tricky algorithm/proof, a thorny design trade-off, a 'is my approach sound?' gut-check, or a multi-model panel on a discrete question. The prompt MUST contain all needed context — Fugu cannot see the repo, files, or this conversation. Do NOT use it for interactive or iterative repo work, multi-step edits, running commands, or anything that needs to read/modify local files — do that yourself. Calls can be slow (tens of seconds).

fugu_second_opinionA

Get a rigorous SECOND OPINION from Sakana Fugu (a separate LLM) on a discrete piece of work. Provide the content to review (code, diff, answer, design, or plan) and a specific question. Fugu acts as a skeptical senior reviewer and returns concrete issues, risks, and improvements. Best for cross-checking your own output with a different model on a self-contained artifact. All needed context must be in content — Fugu cannot see the repo or this conversation. Do NOT use it for interactive/iterative repo work or anything needing local file access. Calls can be slow.
