What problem does it solve? When returning to a project, repo, or plan after time away, it is hard to answer "what changed since I last looked?" and "how deep down this branch am I?" without manually digging through git logs, plans, and file trees. This Skill answers those questions with a fresh, read-only sweep that produces the delta since your last-look anchor plus a done → here → next trajectory rendered as a spine on the trunk or a tree on a branch. ## Core Features & Use Cases - Delta-first orientation: Leads with what changed since a caller-supplied or git-inferred anchor, including honest no-change zones and, on a branch, what landed on the trunk while you were away. - Topology detection: Owns branch detection (git, plan-level, or side-quest) and emits cursor, fork point, ahead/behind counts, and trunk reference so sibling skills never recompute them. - Provenance-tiered, fail-closed output: Every field is tagged attested, inferred, or guessed; barren evidence yields an explicit NO SUBSTRATE card instead of a fabricated tree. - Three output faces: Agents receive a structured YON record; humans receive a plain-language markdown read plus a visual widget or information-complete ASCII twin. - Use Case: You return to a feature branch after two hours and ask what changed — the Skill reports 2 commits and 3 files changed, shows the branch tree with your cursor position, notes one commit landed on main since your fork, and flags the inferred rejoin point as the load-bearing guess. ## Quick Start Ask your agent "what changed since my last look and show me the map of this branch" to get the delta and trajectory for the current project.
