…low engine Introduces a new `copilot.invoke` builtin task that drives schema-guided Copilot agent turns via a new `CopilotClientHost` abstraction backed by `@github/copilot-sdk` 0.3.0. TaskContext is extended with an `outputSchema` field so tasks can use structured output contracts to shape their computation.

I don't see that being added in the code. Also, you already got the input, do you actually need the inputSchema?

You're right -- I added it, didn't use it, and the removal was incomplete. Should be fixed now.
Update decision 0011 to reflect that only outputSchema was added to TaskContext; inputSchema was removed because no consumer needed it. Addresses PR microsoft#2402 review feedback.

Declare concrete builtin tasks with ConcreteTaskDefinition<...> and generic builtin tasks with GenericTaskDefinition<...> instead of the looser TaskDefinition<...> union. Annotations now match what each task actually is (concrete or generic), per the schemas in builtinTaskSchemas.ts. Removes the need for downstream consumers (e.g. tests) to type-assert when reading .inputSchema/.outputSchema.

…concrete Add per-task one-line comments in builtinTasks.ts and builtinTaskSchemas.ts explaining why these are NOT generic over N like their arithmetic siblings (divide: int/int can yield non-int; floor/round/ceil: output is always integer regardless of input).

Revert 88e231e. The TaskDefinition<...> union (concrete | generic) is sufficient for builtin task declarations. Only one downstream consumer (copilotInvoke.spec.ts) needed to read .inputSchema directly, so add a narrow ConcreteTaskDefinition cast there instead of widening the public declaration types of every builtin. Keeps the explanatory comments added in cacd4bc about which builtins are intentionally concrete despite their arithmetic siblings being generic (math.divide, math.floor/round/ceil).

Restore the pre-existing 3-line explanation above math.divide in builtinTaskSchemas.ts that was inadvertently truncated in cacd4bc. The newly added per-task comments on math.floor/round/ceil and on mathDivide in builtinTasks.ts are kept as-is.
