+
+# Find Regression Risk
+
+Detects if a PR's changes could re-introduce previously-fixed bugs by cross-referencing the diff against recently-merged bug-fix PRs.
+
+## Why This Exists
+
+PRs that fix one bug can silently re-introduce another if they modify or revert lines from a prior fix.
+
+**Real-world example:** PR #33908 removed `|| parent is IMauiRecyclerView` from `MauiWindowInsetListener.cs` — a line that PR #32278 had specifically added to fix issue #32436 (increasing gap at bottom while scrolling). The agent approved PR #33908 without detecting this revert, and the exact same bug reappeared as issue #34634.
+
+## When to Use
+
+- ✅ Before approving any PR that modifies platform code
+- ✅ When asked "check for regression risks" or "could this revert a fix"
+- ✅ As part of the `pr-review` skill's Pre-Flight phase
+- ✅ When a PR touches high-churn files (safe area, CollectionView handlers, inset listeners)
+
+## Workflow
+
+### Step 1: Run the Script
+
+```bash
+# Auto-detect implementation files from PR diff
+pwsh .github/skills/find-regression-risk/scripts/Find-RegressionRisks.ps1 -PRNumber XXXXX
+
+# Or specify files manually
+pwsh .github/skills/find-regression-risk/scripts/Find-RegressionRisks.ps1 \
+ -PRNumber XXXXX \
+ -FilePaths @("src/Core/src/Platform/iOS/MauiView.cs","src/Core/src/Platform/Android/MauiWindowInsetListener.cs")
+```
+
+### Step 2: Interpret Results
+
+| Risk Level | Meaning | Action |
+|------------|---------|--------|
+| 🔴 **REVERT DETECTED** | PR removes/modifies lines from a recent bug-fix PR | **MUST** verify the previously-fixed bug doesn't reappear before approving |
+| 🟡 **OVERLAP** | PR modifies the same file as a recent bug-fix but different lines | Note as lower-risk concern |
+| 🟢 **CLEAN** | No recent bug-fix PRs touched these files | No action needed |
+
+### Step 3: Act on Findings
+
+**If 🔴 REVERT DETECTED:**
+
+1. Identify the at-risk issues — the script reports which issues were fixed by the reverted code
+2. Verify the fix still holds — run the test from the original fix PR, or manually verify
+3. Document in PR review — note the revert risk and the verification result
+4. **Do NOT approve** until the risk is mitigated
+
+## What the Script Does
+
+For each implementation file in the PR diff:
+
+1. **Finds recent PRs** — queries `git log` for the last 6 months of changes to that file
+2. **Identifies bug fixes** — checks PR labels AND linked issue labels for `i/regression`, `t/bug`, `p/0`, `p/1`
+3. **Compares diffs** — checks if lines ADDED by a fix PR are being REMOVED by the current PR
+4. **Reports risks** — structured output with file, PR, issue, and reverted line details
+
+## Output Format
+
+Post results using the following format:
+
+```markdown
+## 🔍 Regression Risk Analysis
+
+**PR:** #XXXXX
+**Risk Level:** [🟢 Clean | 🟡 Overlaps Found | 🔴 Revert Risks Detected]

+.SYNOPSIS
+ Finds regression risks by cross-referencing a PR's changes against recently-merged bug-fix PRs.
+
+.DESCRIPTION
+ For each implementation file in the PR diff, this script:
+ 1. Finds recent PRs that modified the same file (last 6 months)
+ 2. Checks if those PRs were bug fixes (via PR labels or linked issue labels)
+ 3. Compares lines removed by the current PR against lines added by recent fix PRs
+ 4. Reports revert risks where fix lines are being undone
+
+.PARAMETER PRNumber
+ The PR number to analyze.
+
+.PARAMETER FilePaths
+ Array of implementation file paths from the PR diff. If not provided, auto-detected from the PR.
+
+.PARAMETER MonthsBack
+ How many months back to search for fix PRs. Default: 6.
+
+.EXAMPLE

+
+# Find Regression Risk
+
+Invoke the **find-regression-risk** skill: read and follow `.github/skills/find-regression-risk/SKILL.md`.
+
+## Context
+
+- **Repository**: ${{ github.repository }}
+- **PR Number**: ${{ github.event.pull_request.number || github.event.issue.number || inputs.pr_number }}
+
+The PR branch has been checked out for you. All files from the PR are available locally.
+
+## Pre-flight check
+
+Before starting, verify the skill file exists:
+
+```bash
+test -f .github/skills/find-regression-risk/SKILL.md
+```
+
+If the file is **missing**, post a comment using `add_comment`:
+
+```markdown
+## 🔍 Regression Risk Analysis
+
+❌ **Cannot analyze**: this PR's branch does not include the find-regression-risk skill (`.github/skills/find-regression-risk/SKILL.md` is missing).
+
+**Fix**: rebase your fork on the latest `main` branch, or use the **workflow_dispatch** trigger (Actions tab → "Find Regression Risk" → "Run workflow" → enter PR number).
+```
+
+Then stop — do not proceed.
+
+## Running the skill
+
+1. Run the regression risk script:
+ ```bash
+ pwsh .github/skills/find-regression-risk/scripts/Find-RegressionRisks.ps1 -PRNumber
+ ```
+2. Read the structured output and the console summary
+3. Post results using `add_comment` with `item_number` set to the PR number
+
+## Posting Results
+
+Call `add_comment` with `item_number` set to the PR number. Format the report based on the risk level:
+
+### If 🟢 Clean (no risks):
+
+```markdown
+## 🔍 Regression Risk Analysis
+
+🟢 **No regression risks detected.** No recent bug-fix PRs were affected by the changes in this PR.
+
+> 👍 / 👎 — Was this analysis helpful? React to let us know!
+```
+
+### If 🟡 Overlaps found:
+
+```markdown
+## 🔍 Regression Risk Analysis
+
+🟡 **Overlaps found** — This PR modifies files that were recently changed by bug-fix PRs, but does not revert their fix lines.
+
+> 👍 / 👎 — Was this analysis helpful? React to let us know!

+
+| File | Recent Fix PR | Fixed Issue | Risk |
+|------|--------------|-------------|------|
+| `{file}` | #{recent_pr} — {title} | {issues} | 🟡 Overlap |
+
+
+```
+
+### If 🔴 Revert risks detected:
+
+```markdown
+## 🔍 Regression Risk Analysis
+
+🔴 **Revert risks detected!** This PR removes code that was specifically added by recent bug-fix PRs. The previously-fixed bugs may re-appear.
+
+**⚠️ Action required:** Verify that the issues listed below do not re-regress before merging.

+| File | Recent Fix PR | Fixed Issue | Risk | Reverted Line |
+|------|--------------|-------------|------|---------------|
+| `{file}` | #{recent_pr} — {title} | {issues} | 🔴 REVERT | `{line}` |
+
+### Recommendations
+
+- Verify issue(s) {issues} do not re-regress with these changes
+- Consider adding tests that cover the previously-fixed scenario
+- If the revert is intentional, document why the old fix is no longer needed
+
+
+```
