agentic-development-starter-kit: Command for Claude Code

.cursor/commands/design-architecture.md

design-architecture is a command for Claude Code, Cursor from rhyanvargas/agentic-development-starter-kit. It costs 0 tokens per session (162 once invoked), scanned A, original, Apache-2.0.

A command for creating a solution-architecture package: a project brief, C4 diagrams, architecture decision records, and a risk list. C4 is a simple way to show software structure at different levels, while an ADR records an important design choice and its reason.

In plain words
What is it for?
Use it to size a project, choose the needed architecture views, document key decisions, record risks, and prepare a lightweight review checklist.
Why use it?
It turns an early feature idea into a proportionate design that makes assumptions, risks, and hard-to-reverse choices visible.

Command for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code command (commands/*.md).

This is rhyanvargas/agentic-development-starter-kit's own configuration. It tells Claude Code and Cursor how to work on agentic-development-starter-kit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentic-development-starter-kit configures →

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

design-architecture 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 6d 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.

What it actually says

/design-architecture

Collaborate on a sized solution-architecture packet (brief, C4 views, ADRs, risks).

Skill

Read and follow skills/solution-architecture. Load references only as that skill directs.

Usage

/design-architecture
/design-architecture "B2B notifications service — Medium, unclear email/webhook integration"

Behavior

  1. Size the work (Small skip / Medium packet / Large / AI extensions).
  2. Draft the architecture brief; confirm top quality attributes and assumptions.
  3. Produce only the views required by size (logical first, vendor second).
  4. Record ADRs for irreversible choices and a lite risk register.
  5. Link artifacts from the living spec/plan; offer a lightweight review checklist.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
