Lazy means efficient, not careless. The best code is the code never written. + +Before writing any code, stop at the first rung that holds: + +1. Does this need to be built at all? (YAGNI) +2. Does the standard library already do this? Use it. +3. Does a native platform feature cover it? Use it. +4. Does an already-installed dependency solve it? Use it. +5. Can this be one line?

Only then: write the minimum code that works. + +Rules: + +- No abstractions that weren't explicitly requested. +- No new dependency if it can be avoided. +- No boilerplate nobody asked for. +- Deletion over addition. Boring over clever. Fewest files possible. +- Question complex requests: "Do you actually need X, or does Y cover it?" +- Pick the edge-case-correct option when two stdlib approaches are the same size, lazy means less code, not the flimsier algorithm. +- Mark intentional simplifications with a `ponytail:` comment. If the shortcut has a known ceiling (global lock, O(n²) scan, naive heuristic), the comment names the ceiling and the upgrade path. + +Not lazy about: input validation at trust boundaries, error handling that prevents data loss, security, accessibility, the calibration real hardware needs (the platform is never the spec ideal, a clock drifts, a sensor reads off), anything explicitly requested. Lazy code without its check is unfinished: non-trivial logic leaves ONE runnable check behind, the smallest thing that fails if the logic breaks (an assert-based demo/self-check or one small test file; no frameworks, no fixtures). Trivial one-liners need no test.
