check-bounded-contexts

check-bounded-contexts is a skill for Claude Code from dykyi-roman/awesome-claude-code. It costs 44 tokens per session (2,656 once invoked), scanned A, original, MIT.

A PHP architecture checker for Domain-Driven Design, a way of structuring software around business areas. It examines boundaries between those areas and creates context-map diagrams.

In plain words
What is it for?
Use it to review bounded contexts, shared code, API relationships, and translation layers between business domains.
Why use it?
It helps find tightly coupled business areas, unclear dependencies, inconsistent terms, and accidental sharing of internal models.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

check-bounded-contexts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Bounded Contexts Analyzer

Overview

This skill analyzes PHP DDD projects for bounded context boundary issues, cross-context coupling, and context mapping violations.

Bounded Context Concepts

Concept Definition Violation Indicator
Bounded Context Explicit boundary with its own domain model Missing namespace separation
Ubiquitous Language Consistent terminology within context Same term, different meanings
Context Map Relationships between contexts Unclear dependencies
Anti-Corruption Layer Translation between contexts Direct foreign model usage
Shared Kernel Deliberately shared code Unintentional sharing
Published Language Public API contracts Breaking changes

Detection Patterns

Phase 1: Context Discovery

# Identify bounded contexts from directory structure
Glob: **/src/**/Domain/*
Glob: **/src/**/Context/*
Glob: **/src/**/Bounded/*
Glob: **/src/**/Module/*

# Namespace-based contexts
Grep: "namespace.*\\\\Domain\\\\|namespace.*\\\\Context\\\\" --glob "**/*.php"

# Composer autoload namespaces
Read: composer.json (check autoload paths for context namespaces)

Context Indicators:

  • Top-level namespace under src/ (e.g., Order, User, Payment)
  • Explicit Domain/ subfolder per context
  • BoundedContext/ or Context/ folder structure

Phase 2: Cross-Context Coupling Detection

Direct Cross-Context Imports
# Find cross-context imports (most critical)
# Pattern: Context A importing from Context B's Domain layer

# Order context importing User domain
Grep: "use Order\\\\.*\\\\Domain" --glob "**/User/**/*.php"
Grep: "use User\\\\.*\\\\Domain" --glob "**/Order/**/*.php"

# General pattern: Domain layer importing another Domain
Grep: "use [A-Z][a-z]+\\\\Domain\\\\" --glob "**/Domain/**/*.php"

# Direct entity references across contexts
Grep: "use.*\\\\Entity\\\\(?!.*\\\\self)" --glob "**/Domain/**/*.php"
Foreign Aggregate References
