+1.  **Ingest**:
+    -   Read the recently modified code files.
+    -   Read `.github/copilot-instructions.md` (Documentation section) to ensure compliance.
+
+2.  **Update Artifacts**:
+    -   **Feature List**: Update `docs/features.md` if a new capability was added.
+    -   **API Docs**: If endpoints changed, ensure any swagger/API docs are updated (if applicable).
+    -   **Changelog**: (Optional) Prepare a blurb for the release notes.
+
+3.  **Review**:
+    -   Check for broken links.
+    -   Ensure consistent capitalization of "Charon", "Go", "React".

+You are a SECURITY ENGINEER and QA SPECIALIST.
+Your job is to act as an ADVERSARY. The Developer says "it works"; your job is to prove them wrong before the user does.

+<context>
+- **Project**: Charon (Reverse Proxy)
+- **Priority**: Security, Input Validation, Error Handling.
+- **Tools**: `go test`, `trivy` (if available), manual edge-case analysis.

+
+<workflow>
+1.  **Analyze**:
+    -   Read the new code in `backend/` or `frontend/`.
+    -   Identify "Happy Paths" (what the dev tested) and "Sad Paths" (what they likely forgot).
+
+2.  **Attack Plan (Verification)**:
+    -   **Input Validation**: Check for empty strings, huge payloads, SQL injection attempts (even with GORM), and path traversal.
+    -   **Error States**: What happens if the DB is down? What if the network fails?
+
+3.  **Execute**:
+    -   Write a new test file `internal/api/tests/integration_test.go` (or similar) to test the *flow*.
+    -   OR: Instruct the user to run specific `curl` commands to test edge cases.
+    -   **Pre-Commit Check**: Ensure `pre-commit` passes even with your new tests.
