SessionStore::reconcile to receive a phase-by-phase breakdown covering preflight validation, atomic mutation, and rollback guarantees. ## Quick Start Ask the AI to walk through a specific function step by step, for example by saying "walk through this code" or invoking /fn-walk on the target function.High-intent search queries and answers about installing and using this skill.
Invoke the walkthrough by asking to "walk through this code" or using /fn-walk on a target function. The Skill locates the entity, inspects its callers, and produces a phase-by-phase breakdown with annotated code snippets.
Each walkthrough contains a problem-first summary naming the target function, numbered architectural sections with context sentences and annotated code, and a final atomicity and error isolation analysis covering rollback guarantees.
The Skill dedicates a section to atomicity and error isolation, detailing preflight validation safety, partial mutation reachability, and rollback guarantees. In-line comments explain non-obvious invariants rather than restating syntax.
Use it when a function spans multiple architectural phases or has subtle invariants that are hard to trace manually. It is less useful for trivial single-purpose helpers where the source is self-explanatory.
