Interpretation is structured for decision-making; original keeps the upstream SKILL.md unchanged.

Decide Fit First

Core job: Agent skill for arch-system-design - invoke with $agent-arch-system-design name: "system-architect" description: "Expert agent f…
Best fit: Use it when the task has reusable inputs, steps, and validation criteria rather than a one-off answer.
Avoid forcing it: If the source lacks commands, platform support, or external-service evidence, keep those fields unknown instead of guessing.

Design Intent

Structure: The skill is organized around “Key responsibilities:”, “Best practices:”, “Deliverables:”, “Decision framework:”, showing how the author expects the agent to judge fit, collect context, and produce verifiable output.
Trigger evidence: Prioritize the author’s wording around when to use it, what context to collect, and what output shape to produce.
Evidence boundary: Author text states facts, repository files prove commands and paths, and Fluxly only adds fit, limits, and usage judgment.

How To Use It

Inputs: Provide target material, scope, expected result, forbidden changes, and validation method.
Invocation: Name agent-arch-system-design directly; if the source includes slash commands, start with the command and then add task context.
Validation: Start small and check whether the result follows “Key responsibilities: / Best practices: / Deliverables:” before expanding.

Boundaries And Review

Dependencies: It usually needs no extra API key, so start with a small validation task.
Permissions: Declared permissions include read / write / shell-exec; ask the agent to state file, command, and rollback boundaries before acting.
Quality bar: A useful result names the deliverable, evidence, and next action. Generic prose means the task needs tighter context.

System Architecture Designer

You are a System Architecture Designer responsible for high-level technical decisions and system design.

Key responsibilities:

Design scalable, maintainable system architectures
Document architectural decisions with clear rationale
Create system diagrams and component interactions
Evaluate technology choices and trade-offs
Define architectural patterns and principles

Best practices:

Consider non-functional requirements (performance, security, scalability)
Document ADRs (Architecture Decision Records) for major decisions
Use standard diagramming notations (C4, UML)
Think about future extensibility
Consider operational aspects (deployment, monitoring)

Deliverables:

Architecture diagrams (C4 model preferred)
Component interaction diagrams
Data flow diagrams
Architecture Decision Records
Technology evaluation matrix

Decision framework:

What are the quality attributes required?
What are the constraints and assumptions?
What are the trade-offs of each option?
How does this align with business goals?
What are the risks and mitigation strategies?

Fluxly profile Author and license come from source; runtime, permissions, and network are Fluxly detections or estimates

Fluxly category: Design
Author-declared agents: No explicit declaration found; this is not inferred or tested compatibility
Static check: 88 / 100 · heuristic scan, not runtime safety proof
Author / version / license: @ruvnet · no license declared
Fluxly token estimate: Lean
Fluxly setup estimate: Guided setup
External API key: No requirement detected
Detected OS requirements: Unspecified
Runtime requirements: Unspecified
Detected file/system behavior: Read-only
Write / modify
Shell exec
Detected network behavior: Local-only
Install commands: None (reference only)

Profile is derived at build time from SKILL.md and install vectors. Subject to drift from author intent.

Heads up: 未限定 allowed-tools，默认拥有全部工具权限。
