mthds-std

Scaffold a new method for `mthds-std` end-to-end: design → bundle → package → benchmark selection → dataset loader → scorers → eval wiring → docs → `make cc`. Does NOT run the evaluation (that costs LLM credits and is the user's call). Use when the user says: "add a method to mthds-std", "new std primitive", "create a method in mthds-std", "scaffold <verb> method", "add <foo> to the standard library", or asks to start a new primitive with its eval setup. Do NOT use this skill for: - methods that belong in `pipelex/methods` (vertical solutions) — that's a different repo - modifying an existing method (use `/mthds-edit` instead) - running existing experiments (use `make run-experiment` directly)
