ponytail

Activate ponytail mode to enforce a simplicity ladder: skip speculative features, prefer stdlib and native platform features, and ship the shortest working diff. Unrequested abstractions like single-implementation interfaces and unused config are blocked by default.

Use the command /ponytail lite, full, or ultra to switch levels. Lite names a lazier alternative while building what was asked, full enforces the ladder as the default, and ultra challenges the requirement itself before writing code.

Never simplify away input validation at trust boundaries, error handling that prevents data loss, security measures, accessibility basics, or anything explicitly requested. Hardware calibration knobs should also be preserved since physical systems drift.

Non-trivial logic such as branches, loops, parsers, or money paths still gets one minimal runnable check, like an assert-based demo or a single small test file. Trivial one-liners need no test, and no frameworks or fixtures are added unless requested.

Say "stop ponytail" or "normal mode" to revert to standard behavior. The active level otherwise persists until changed or the session ends.
