Senior Architect is an agent skill from alirezarezvani/claude-skills. This skill should be used when the user asks to "design system architecture", "evaluate microservices vs monolith", "create architecture diagrams", "analyze dependencies", "choose a database", "plan for scalability", "make technical decisions", or "review system design". Use for architecture decision records (ADRs), tech stack evaluation, system design reviews, dependency analysis, and generating architecture diagrams in Mermaid, PlantUML, or ASCII format.
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `references/architecture_patterns.md`, `references/system_design_workflows.md` and `references/tech_decision_guide.md`).
It sits in Development, covering Diagrams, Architecture decision records and Microservices. It works with Mermaid. The repository describes itself as: 380 Claude Code skills & agent skills & plugins (30+ Agents, 70+ custom commands, 380+ skills, customizable references, scripts)for Claude Code, Codex, Gemini CLI, Cursor, and 8… The licence is MIT.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 19392f7. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Senior Architect loads about 2.7k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 703 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Architecture Assessment
=======================
Detected pattern: Layered Architecture (confidence: 85%)
Structure analysis:
✓ controllers/ - Presentation layer detected
✓ services/ - Business logic layer detected
✓ repositories/ - Data access layer detected
⚠ models/ - Mixed domain and DTOs
Issues:
- LARGE FILE: UserService.ts (1,847 lines) - consider splitting
- MIXED CONCERNS: PaymentController contains business logic
Recommendations:
1. Split UserService into focused services
2. Move business logic from controllers to services
3. Separate domain models from DTOsUse when choosing a database for a new project or migrating existing data.
Step 1: Identify data characteristics
| Characteristic | Points to SQL | Points to NoSQL |
|---|---|---|
| Structured with relationships | ✓ | |
| ACID transactions required | ✓ | |
| Flexible/evolving schema | ✓ | |
| Document-oriented data | ✓ | |
| Time-series data | ✓ (specialized) |
Step 2: Evaluate scale requirements
100M records, global distribution → CockroachDB, Spanner, or DynamoDB
Step 3: Check consistency requirements
Step 4: Document decision Create an ADR (Architecture Decision Record) with:
Quick reference:
PostgreSQL → Default choice for most applications
MongoDB → Document store, flexible schema
Redis → Caching, sessions, real-time features
DynamoDB → Serverless, auto-scaling, AWS-native
TimescaleDB → Time-series data with SQL interfaceUse when designing a new system or refactoring existing architecture.
Step 1: Assess team and project size
| Team Size | Recommended Starting Point |
|---|---|
| 1-3 developers | Modular monolith |
| 4-10 developers | Modular monolith or service-oriented |
| 10+ developers | Consider microservices |
Step 2: Evaluate deployment requirements
Step 3: Consider data boundaries
Step 4: Match pattern to requirements
| Requirement | Recommended Pattern |
|---|---|
| Rapid MVP development | Modular Monolith |
| Independent team deployment | Microservices |
| Complex domain logic | Domain-Driven Design |
| High read/write ratio difference | CQRS |
| Audit trail required | Event Sourcing |
| Third-party integrations | Hexagonal/Ports & Adapters |

Senior Architect is an agent skill from alirezarezvani/claude-skills. This skill should be used when the user asks to "design system architecture", "evaluate microservices vs monolith", "create architecture diagrams", "analyze dependencies", "choose a database", "plan for scalability", "make technical decisions", or "review system design".
Senior Architect fits situations like: asks to design system architecture; evaluate microservices vs monolith; create architecture diagrams; analyze dependencies.
Run `npx skills add alirezarezvani/claude-skills --skill senior-architect -a claude-code`. Or copy the skill folder (engineering-team/skills/senior-architect in alirezarezvani/claude-skills) into .claude/skills/senior-architect in your project. Claude Code loads it when a task matches its description.
Run `npx skills add alirezarezvani/claude-skills --skill senior-architect -a codex`. Or copy the skill folder (engineering-team/skills/senior-architect in alirezarezvani/claude-skills) into .agents/skills/senior-architect in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add alirezarezvani/claude-skills --skill senior-architect -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/senior-architect, .gemini/skills/senior-architect, .github/skills/senior-architect and .opencode/skills/senior-architect in your project.
Going by SKILL.md and its folder, Senior Architect needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3; Node.js; Docker.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Senior Architect is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.7k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 9.7k tokens, read only when the agent opens those files.
