Ask one question

Goal: get the right context for a task without first deciding whether to survey, focus, or search. Hand Fuse the task and a budget; it picks the strategy.

This is the fuse_ask MCP tool. It collapses the survey-then-scope sequence into a single call.

Do it

fuse_ask(
  path="C:/Projects/MyApp/src",
  task="where is the discount applied at checkout?",
  tokenBudget=20000
)

How it chooses

Fuse reads the task text and picks a strategy:

• A broad question (architecture, overview) becomes a skeleton.
• A task naming one type becomes a focus on that type.
• Anything else becomes a search.

Focus falls back to search when the named type does not resolve. The result is prefixed with a one-line note saying which strategy it chose, so the agent knows how the context was assembled, and it is packed to the tokenBudget (default 20,000).

When to use it

Use fuse_ask as the default first call for an agent that has a task in natural language but does not yet know the codebase. Use the specific tools (fuse_skeleton, fuse_focus, fuse_search, fuse_changes) when you already know which strategy you want and want to control its parameters. The progressive flow is in Context for an agent.
