From c3f1931102c03766d4c222399cd32c8226c2be19 Mon Sep 17 00:00:00 2001 From: shauryagangrade <288927048+shauryagangrade@users.noreply.github.com> Date: Wed, 11 Nov 2026 17:48:54 +0530 Subject: [PATCH 1/7] Add a smaller intent-drift check grounded in a real Copilot session Replace the heuristic scoring engine from #6242 with a short diff-review procedure. The check uses the request's acceptance test to classify each change as required or out of scope, reverts only out-of-scope hunks, and re-runs the check. The worked example is a real GitHub Copilot CLI session where a test fix also changed unrelated behavior; the check caught the scope creep and restored the minimal fix. --- docs/README.skills.md | 1 + skills/intent-drift/SKILL.md | 69 +++++++ skills/intent-drift/examples/real-session.md | 189 +++++++++++++++++++ 3 files changed, 259 insertions(+) create mode 100644 skills/intent-drift/SKILL.md create mode 100644 skills/intent-drift/examples/real-session.md diff --git a/docs/README.skills.md b/docs/README.skills.md index 26484ccb6..33065561c 100644 --- a/docs/README.skills.md +++ b/docs/README.skills.md @@ -252,6 +252,7 @@ See [CONTRIBUTING.md](../CONTRIBUTING.md#adding-skills) for guidelines on how to | [import-infrastructure-as-code](../skills/import-infrastructure-as-code/SKILL.md)
