git diff --numstat, so the headline totals always equal the sum of the rows. ## Core Features & Use Cases - True-by-construction recap: Per-file path, status, added, and removed values come straight from git; the model writes only the labels and groupings, and a bundled value gate rejects any record whose totals drift from its rows. - Triple output bundle: Emits a diff-recap/1 YON record, a PR-pasteable markdown summary, and an information-complete ASCII twin (plus an optional widget on Claude Code), with no hosted service dependency. - Fail-closed behavior: No git source or an empty diff produces an honest NO DIFF card with gate_status=barren instead of a fabricated recap. - Use Case: Before opening a pull request, run it on your branch to get a grouped change table (feature/tests/docs) with git-attested counts you can paste directly into the PR description, then hand the same change-set to a cold review. ## Quick Start Ask the agent to recap the changes in the current branch with /diff-recap and paste the resulting summary into your pull request.High-intent search queries and answers about installing and using this skill.
Invoke /diff-recap with a range (defaulting to the working tree against HEAD, an A..B range, or --staged) and an intent describing the PR's goal. It runs git diff --name-status and --numstat, groups files by area, and emits a paste-ready markdown table plus an ASCII twin.
Per-file path, status, added, and removed values are transcribed verbatim from git diff --numstat; the model writes only labels and groups. A bundled value gate (diff-recap-check.mjs) rejects any record whose headline totals do not equal the sum of its rows, and can cross-check rows against the real numstat.
orient-map shows the shape and delta of the work and orient-status reports position and ETA, while diff-recap recaps what a concrete change-set contains for a reviewer. It is also not a code review; it summarizes what changed without judging quality.
Yes. The information-complete ASCII twin is always emitted and is the only render in runtimes without the visualize tool, and agent consumers receive the YON record only. It has zero external or hosted dependencies beyond git itself.
It fails closed: the record sets gate_status to barren and attested to false, carries no file rows, and renders a NO DIFF card instead of fabricating a recap. A clean verdict requires attested=true from a real git source.
