complexity-cuts — Lower Big-O on Existing Code prevents bad complexity before code is written. complexity-cuts fixes it after the fact: code already exists, it works, but its time or space complexity is worse than necessary. Violating the letter of these rules is violating the spirit of the skill. Adapting "just a little" is how a faster-but-wrong rewrite ships. When to Use This Skill Use complexity-cuts when refactoring existing code that has poor Big-O: - Nested loops, or worse scans, repeated work, redundant allocations, blown memory. - Stated symptoms: "this is slow on large inputs", "tim…
