Prompt

A developer ran a pre-commit check after updating only `application.yml` and `README.md`. What specific message or response should be returned when checking modified files in incremental mode?

What was checked, without and with the skill
Checked	Without skill	With skill
States that no Java files were changed when no Java files are modified.	Missed	Passed

DDD Compliance Check

Two-mode DDD compliance validation for Java projects. Auto-detects mode from user's trigger phrase.

Mode Detection

Trigger Phrases	Mode	Scope
"check my changes", "pre-commit", "review this code", "validate my code"	Incremental	`git diff` only
"full audit", "architecture review", "DDD compliance report", "check entire project", "pre-release"	Full	All Java files

Incremental Mode

Workflow

Find changed files: git diff --cached --name-only --diff-filter=ACMR | grep '\.java$' (also check unstaged and HEAD diff)
Classify by layer: Map package path to layer using layer rule files in references/.
Load relevant rules: Only load rule files matching changed layers. Always load references/anti-patterns.md.
Check each file: Validate structural rules (base class, package, naming), dependency rules (no forbidden imports), anti-patterns.
Report: Per-file violations with severity and fix. Skip "looks good" for clean files.

If no Java files changed: "No Java files changed — nothing to check."

Full Mode

Workflow

Discover: find . -name "*.java" -not -path "*/target/*" -not -path "*/test/*" | sort
Load all rules: Read every layer rule file in references/. Load references/base-classes-reference.md and references/exception-handling.md as needed.
Layer-by-layer audit: Group by layer, check package, base class, naming, dependencies, structure, exception mode.
Cross-layer: Verify dependency direction (grep -r "import org\.bookiosk\.ddd\."), detect anemic models, check exception boundaries.
Report: Executive summary with compliance score, per-layer breakdown, anti-patterns section, dependency graph, ranked recommendations.

See examples/violation-report.md for sample output.

Layer Checklists

See references/shared-checks.md for the complete severity table (CRITICAL/HIGH/MEDIUM/LOW) and per-layer checklists.
