What problem does it solve? Recurring bugs and design pitfalls get fixed once but forgotten, so the same class of mistake resurfaces in later planning and implementation work. This Skill captures a recurring rule into a persistent, append-only lessons register that future framing, planning, implementation, and review runs re-read as a prior. ## Core Features & Use Cases - Structured four-field interview: Collects Context, Problem, Rule, and Applies-to fields from the user via guided prompts, with no pre-filling so the user owns the wording. - Canonical entry format: Renders each lesson as a markdown block with an imperative H2 rule title, then asks for explicit confirmation before saving. - Self-bootstrapping append-only register: Creates context/foundation/lessons.md with a canonical header on first use, then appends new entries without reordering or editing existing ones. - Use Case: After noticing that feature flags keep shipping without expiration dates, invoke the skill with that observation, answer the four prompts, and the rule is recorded so every future plan and review weighs it. ## Quick Start Ask the assistant to record a recurring rule using the 10x-lesson skill, optionally including a one-line description of the rule you want captured.
