name: architecture description: Query and visualize the full project architecture. Use this during project onboarding, before code reviews, before adding new domains, or whenever you need to understand the tech stack. Responds to questions like "show me the overall structure", "list all APIs", "what's the tech stack", or "explain the domain structure". Triggers on /architecture. version: 1.1.0 updated: 2026-02-11

Architecture Map

Query and visualize the full project architecture. Get a clear picture of domain structure, API catalog, layer layout, and tech stack at a glance.

---

Skill Triggers

• /architecture — Full architecture overview
• /architecture domains — Domain structure
• /architecture api — API catalog
• /architecture layers — Layer-by-layer structure
• /architecture tech — Tech stack
• /architecture <domain-name> — Specific domain detail
• "show me the architecture"
• "understand the overall structure"
• "list all APIs"

---

Absolute Prohibitions

1. Do not modify code — this skill is read/visualize only.
2. Do not guess at structure — analyze based on the actual filesystem.
3. Do not edit architecture documents directly — that is the responsibility of the architecture-updater.js hook.

Execution Steps

Receive /architecture [subcommand]
    |
    v
[1] Parse subcommand
    |
    v
[2] Check existing architecture documents (.claude/architecture/)
    |
    v
[3] Explore project structure
    |
    v
[4] Analyze by subcommand
    |
    +--> overview: full architecture overview
    +--> domains: domain structure
    +--> api: API endpoints
    +--> layers: layer structure
    +--> tech: tech stack
    +--> <domain-name>: domain detail
    |
    v
[5] Output visualization

Subcommands

Subcommand	Description
(none)	Full architecture overview
domains	Domain structure + Mermaid diagram
api	API endpoint catalog
layers	Layer-by-layer structure + violation detection
tech	Auto-detected tech stack
<domain-name>	Detailed analysis of a specific domain

---

Domain Discovery Patterns

Pattern	Example
src/domains/<name>/	src/domains/member/
domains/<name>/	domains/order/
packages/<name>/	packages/auth/
modules/<name>/	modules/payment/

Layers vs. Domains:

• Layers (not domains): api/, services/, models/, utils/
• Domains (analysis targets): order/, member/, product/

---

Layer Identification Patterns

Layer	Directory Patterns
API/Route	api/, routes/, controllers/
Service	services/, usecases/
Model/Entity	models/, entities/
Schema	schemas/, dto/
Repository	repositories/, dao/
Infrastructure	infrastructure/, adapters/
Test	tests/, __tests__/

---

Tech Stack Detection

Category	Detection Source
Language	File extension distribution
Framework	Config files, import patterns
Database	Config files, ORM imports
Infrastructure	Docker, K8s config files
CI/CD	Workflow files

# Check config files
cat package.json pyproject.toml requirements.txt 2>/dev/null | head -30

# Infrastructure config
ls Dockerfile docker-compose*.yml .github/workflows/ 2>/dev/null

---

Data Source Priority

Priority	Source
1	.claude/architecture/*.md (hook-generated documents)
2	.claude/project-team.yaml (project config)
3	Real-time filesystem scan

Hook Integration

Aspect	Hook (architecture-updater.js)	Skill (/architecture)
Trigger	Auto-runs after Write/Edit	On user request
Scope	Incremental, based on changed files	Full or per subcommand
Output	Auto-updates documents	Interactive visualization
Purpose	Document maintenance	Architecture understanding

---

Related Skill Integration

Skill	When to Link	Purpose
/deps	After full analysis	Deep dependency analysis
/impact <file>	When a specific file is of interest	Change impact scope
/changelog <domain>	After domain detail view	Change history
/coverage	After layer analysis	Test coverage
