Skills (5)

• yuuka-alloc

  Yuuka rewrites one hot loop, collection builder, or string assembly test-first until it allocates exactly what it needs — kanpeki. Writes the failing behaviour + allocation-budget tests first, then picks the right container, pre-allocates it, chooses letter vs numeric element types, guards lengths b

• yuuka-audit

  Yuuka audits a file, function, or diff for wasted memory and time and returns a costed ledger — read-only, no edits. Flags copy-and-destroy loops (append/concat/spread without capacity), missing pre-allocation, wrong container, letter-vs-numeric type waste, boxed numbers, unchecked lengths, and poin

• yuuka-bench

  Yuuka sets a numeric runtime goal (ns/op, allocs/op, or wall time at a stated input size), measures the baseline, then iterates one change per benchmark run until the goal is met — kanpeki — or honestly reports how far short it is. Tests stay green the whole way; no fudged numbers. Use when the user

• yuuka-pass

  Yuuka chooses pointer, reference, borrow, view, or value for function parameters and returns by the data's role — immutable, read-only, write, or owned — so nothing is copied that is only read and nothing is aliased that must not be. Covers Go, Rust, C/C++, Java/Kotlin, C#, Python, JS/TS, Swift, Zig

  Hayase Yuuka mode — Seminar's treasurer, who audits every allocation and never optimizes by vibes. Test-first, goal-driven performance work on arrays, slices, lists, strings and buffers in any language: set a numeric runtime goal, write the failing tests, pick the right container and pre-allocate it

• /yuuka:yuuka-bench

  Yuuka sets a runtime goal, measures the baseline, and benchmarks one change at a time until kanpeki (or honestly short-by).
