INTERNAL DEV WORKFLOW for WpfHexEditor — Claude self-invokes after editing any *.whfmt under Core/WpfHexEditor.Core.Definitions/FormatDefinitions/ or the whfmt.schema.json. Domain checks NOT covered by build gate EmbeddedWhfmt_Tests (parse-only) or nuget-guard (public API): JSONC parse with /* */ header tolerated (per feedback_whfmt_guard), version monotone vs git HEAD (per feedback_whfmt_version), required schema fields (formatName, formatId, extensions, category, description), formatId uniqueness across catalog, magic-signature collisions, detection.strength enum (catches typos before SignatureStrength converter crash — bug_signaturestrength_converter), and placeholder/variables drift. Skip on: files outside FormatDefinitions/, Tests/, Samples/, doc-only or comment-only edits.
INTERNAL DEV WORKFLOW for WpfHexEditor — Claude self-invokes after editing any *.cs or *.csproj that belongs to one of the 13 packages published on nuget.org by abbaye (WpfHexEditor.Core.ByteProvider, .BinaryAnalysis, WPFHexaEditor, WpfCodeEditor, WpfDocking, WpfColorPicker, WpfTerminal, whfmt.Analysis/.Backfill/.CodeGen/.Fuzz/.Validate/.FileFormatCatalog). Protects the standalone-mode contract when IDE features are added: detects IDE-only references leaking into a NuGet package, TFM drift, UseWPF leak on core-xplat packages, WPF/WinForms usings in core-xplat, and public-API regressions vs git HEAD (api-removed, api-renamed). Extending the API is always allowed; removing/renaming is not. Skip on files outside protected packages, Tests/, Samples/, *.Designer.cs, *.g.cs.
INTERNAL DEV WORKFLOW for WpfHexEditor — Claude self-invokes this skill BEFORE any non-trivial edit AND AFTER multi-file changes, to enforce CLAUDE.md rules (functions <=25 lines, classes <=300, 1-file-1-responsibility, module boundaries, forbidden patterns). Auto-trigger on: edits >50 lines, new files, refactors, module-crossing changes, plugin/SDK touches, performance-sensitive paths (HexEditor buffer, CodeEditor render, viewport, drag/scroll), Roslyn diagnostics work. Skip on: doc-only, resx-only, comment fixes, single-line bug fixes, single-file <20-line edits.
INTERNAL DEV WORKFLOW for WpfHexEditor — Claude self-invokes after editing C# files that touch IDisposable, events, FileStream, Process, Timer, or files under Services/, *Manager.cs, *Service.cs, *Watcher*, *Adapter.cs. Detects: event handlers added without unsubscribe, IDisposable without Dispose, missing GC.SuppressFinalize, FileStream without using, Timer not stopped, Process not disposed, static event collections, weak-event candidates, hardcoded secrets. Skip on: Tests/, Samples/, *.Designer.cs, *.g.cs, generated code.
INTERNAL DEV WORKFLOW for WpfHexEditor — Claude self-invokes on two scopes: (1) PARITY — after editing any *.resx (base or satellite), verifies the 28-language satellite parity (missing/orphan keys, placeholder drift, untranslated). (2) SOURCE — after editing *.xaml or *.cs under App/, Editors/, Plugins/, Core/, Controls/, advisory checks for: DynamicResource on loc keys (must be StaticResource), hardcoded user-visible string literals, IdeMessageBox.Show literals, legacy MessageBox.Show usage (ADR-009), and missing LocalizedResourceDictionary wiring (ADR-005). All SOURCE findings are warn-only. Distinct from xaml-guard (which only checks Designer.cs parity for the base resx). Skip on: Themes/, ColorPicker, Designer.cs/g.cs, Tests/, Samples/, pure structural XAML edits.
INTERNAL DEV WORKFLOW for WpfHexEditor — at the start of a new task turn, Claude self-invokes to surface relevant memory entries based on keywords in the user prompt (WebView2, dock, tab, XAML patcher, loc, resx, viewport, drag/scroll, etc.). Prevents re-discovering documented bugs and re-making the mistakes captured in feedback_* memories. Skip on: continuation of an in-progress task in the same turn, purely social messages, single-line follow-ups.
INTERNAL DEV WORKFLOW for WpfHexEditor — Claude self-invokes after editing C# in render/layout/scroll hot paths (HexEditor/, CodeEditor/Rendering*, *Viewport*, *GlyphRun*, *Renderer*, *ScrollHandler*, OnRender, MeasureOverride, ArrangeOverride) to detect allocations and patterns that cause jank or GC pressure. Skip on: tests, mocks, designer files, non-render code in non-hot directories.
INTERNAL DEV WORKFLOW for WpfHexEditor — Claude self-invokes after creating new C# files OR adding >50 lines to existing classes (especially under Services/, Managers/, *Manager.cs, *Service.cs). Heuristics that CORRELATE with SOLID violations: SRP (mixed UI+IO concerns, classes >300 lines + >15 public methods), OCP (massive switch statements >10 cases), DIP (newing services instead of injecting, static singleton mutation), ISP (fat interfaces, NotImplementedException stubs). LSP is out of scope (impossible to detect mechanically). All findings are ADVISORY (warn-only). Skip on: Tests/, Samples/, *.Designer.cs, *.g.cs.
