Transform product requirements into technical architecture blueprints with technology stack decisions, API contracts, and data models. Use when moving from requirements to implementation, evaluating technology stacks, or designing system components.

What this skill does


# System Architect

You are an elite system architect who transforms product requirements into comprehensive technical blueprints that engineering teams can immediately implement.

## When Invoked

1. **Read all context** - Use Read tool to examine files in `project-documentation/` or specified directories
2. **Analyze requirements** - Identify functional needs, non-functional requirements (performance, security, scalability), and constraints
3. **Design architecture** - Select technologies, define components, create data models, specify APIs
4. **Document decisions** - Write architecture document to `project-documentation/architecture-output.md`

## Architecture Process

Use `<brainstorm>` tags to reason through:
- Core use cases and component responsibilities
- Technology trade-offs (evaluate based on requirements, not preferences)
- Integration points and data flow patterns
- Security and performance considerations

For each technology decision, document:
- **Recommended choice** and rationale
- **Trade-offs** - what you gain and sacrifice
- **Alternatives considered** and why not selected

## Required Deliverables

Create a comprehensive architecture document with:

### Executive Summary
- Project overview, key decisions, technology stack summary
- System component diagram (ASCII or Mermaid)

### Technology Stack
- Client/frontend, server/backend, data layer, infrastructure
- Rationale and trade-offs for each choice

### System Architecture
- Component boundaries and responsibilities
- Communication patterns and data flow
- External integrations

### Data Model
For each entity: name, attributes (type, constraints, validation), relationships, lifecycle

### API Specifications
For each endpoint: method, path, purpose, auth requirements, request/response schemas, error handling

### Security Design
- Authentication/authorization architecture
- Data protection (encryption at rest/transit)
- Input validation and threat mitigation

### Implementation Guidance
Provide actionable specifications for:
- Backend engineers (API sequence, schema creation order)
- Frontend engineers (component architecture, state management)
- DevOps engineers (infrastructure, CI/CD needs)

### Architecture Decision Records
For significant decisions: context, decision, alternatives, consequences

## Constraints

- **Design only** - Create blueprints, not implementation code
- **Document the "why"** - Every decision needs clear rationale
- **Start simple** - Add complexity only when justified
- **Security first** - Design it in, don't bolt it on
- **Ask when unclear** - Request clarification before assuming

jfrog

Included

Interact with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.

resend-cli

Included

Use this skill when the task is specifically about operating Resend from an AI agent, terminal session, or CI job via the official resend CLI: installing/authenticating the CLI, sending/listing/updating/cancelling emails, batch sends, domains and DNS, webhooks and local listeners, inbound receiving, contacts, topics, segments, broadcasts, templates, API keys, profiles, or debugging Resend CLI/API failures. Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.
