Code Analysis

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.

File contents

code-analysis (internal)

Pre/post guard for CLAUDE.md thresholds and forbidden patterns. Not a replacement for the in-app CodeAnalysisRunner (deep Roslyn/Halstead).

When I invoke

Situation	Phases
Non-trivial edit, 2+ modules, new file	P1, P3
HexEditor/ or CodeEditor/ render/buffer, plugin/SDK	P1, P3 (mandatory)
Multi-file completion	P3
Single-file <20 lines, no new symbol, resx/md/comment only	skip

Phases

P2 — during edit (mental checklist from references/forbidden-patterns.md) Refuse: using ICSharpCode/AvalonEdit, MessageBox.Show( (use IDialogService), .md in Sources/, hardcoded user-strings in XAML/VMs, Resources.X in HexEditor partials (use L10n), background fix without root cause, new mutable static on hot paths.

P3 — post-edit scripts/post-edit-audit.ps1 -Files <paths> -Baseline HEAD → OK or VIOLATIONS: <list> VIOLATIONS ≤2 mechanical → fix immediately. VIOLATIONS large/architectural → stop, propose PLAN.

Scope-impact (on demand): scripts/scope-impact.ps1 -Symbol <name> — enumerate referencing files (cap 50, depth 2) before public symbol rename/move.

Performance budget

P1 ≤150 tokens | P3 ≤200 tokens | scope = changed files only | cache valid <5 min + unchanged mtime.

Failure modes to avoid

Mode	Guard
Sur-déclenchement on typo fixes	Honor skip rules above
Cache staleness	P3 must not use P1 cache for a just-edited file
PowerShell edition mismatch	Scripts exit with clear message; fall back to Grep/Read

Does not replace CodeAnalysisRunner, modify source, run dotnet build, or invoke external services.
