Xaml Guard

INTERNAL DEV WORKFLOW for WpfHexEditor — Claude self-invokes after editing any *.xaml, *.resx, or *Resources.Designer.cs file to detect regressions in the high-incident XAML/resx/loc domain (hardcoded user-strings, XAML patcher corruption, resx malformed, key drift, HexEditor Resources alias, MessageBox in code-behind, ContextMenu transparency, DockPanel-row alignment). Skip on: pure structural attribute edits (Grid.Row, Margin, Width).

File contents

xaml-guard (internal)

Layered guard for the highest-incident surface in project memory: adr_007_xaml_patcher_bug, feedback_resx_satellite_corruption, feedback_localization_new_strings, feedback_resources_alias_hexeditor, bug_contextmenu_transparent, feedback_overflow_menu_alignment.

When I invoke

Situation	Run?
Edit `.xaml`, `.resx`, `*Resources.Designer.cs`, new UserControl/Window/Page	yes
Pure structural attribute edit (Grid.Row, Margin, Padding), code-behind `.xaml.cs` only	no

Pipeline

scripts/xaml-check.ps1 -Files <paths> for XAML rules.
scripts/resx-validate.ps1 -File <path> per resx (parse + Designer parity).
→ XAML: <n> issues | LocCoverage~<pct>% or OK

10 rules

Full regex + exceptions: references/xaml-rules.md.

Rule	Anchor memory
`hardcoded-text`	`feedback_localization_new_strings`
`missing-dynamic`	`project_phase6_localization_complete`
`patcher-corruption`	`adr_007_xaml_patcher_bug`
`xmlns-mangle`	`adr_007_xaml_patcher_bug`
`resx-malformed`	`feedback_resx_satellite_corruption`
`designer-drift`	detected by resx-validate
`hexeditor-resources`	`feedback_resources_alias_hexeditor`
`messagebox-show`	`adr_009_themed_messagebox`
`static-color-no-alpha`	`bug_contextmenu_transparent`
`dockpanel-row-grid`	`feedback_overflow_menu_alignment`

Output

XAML: 2 hardcoded-text, 1 missing-dynamic | LocCoverage=78%
  MainWindow.xaml:42  hardcoded-text  Header="Settings"
  Toolbar.xaml:15     missing-dynamic Tooltip="Save"

LocCoverage is approximate (DynamicResource count vs attribute string count). Does not rewrite XAML, translate strings, or verify XAML compiles.

False positives: technical values (Style="{StaticResource …}", x:Key=…, FontFamily="Segoe UI", brush names) are whitelisted — see references/xaml-rules.md.
