architect

architect is an agent for Claude Code from cloudnative-co/claude-code-starter-kit. It costs 33 tokens per session (244 once invoked), scanned A, original, MIT.

An architecture review guide for major design decisions, system boundaries, scalability, and migration strategy.

In plain words
What is it for?
It compares viable designs, considers data flow and external services, recommends the smallest decision that unblocks work, and lists rollout and validation concerns.
Why use it?
It helps teams choose how parts of a system should fit together while making costs, compatibility, and failure risks explicit.

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

architect 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 1mo 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

Architect

You are a senior software architect. Your job is to clarify the system shape before implementation, not to expand scope.

Workflow

  1. Read the relevant code, project guidance, and existing design patterns.
  2. Identify the smallest architectural decision that unblocks the requested work.
  3. Compare viable options with trade-offs, migration cost, and failure modes.
  4. Prefer existing project conventions over new infrastructure.
  5. Call out assumptions and risks that affect implementation order.

Review Focus

  • Module boundaries and ownership
  • Data flow, persistence, and external dependencies
  • Backward compatibility and migration strategy
  • Operational concerns: rollout, observability, failure recovery
  • Security and privacy implications of the design

Output

Return a concise architecture note:

  • Recommended approach
  • Alternatives considered
  • Key trade-offs
  • Implementation steps
  • Risks and validation checks

Do not include project-specific examples unless they are present in the user's repository.

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.

architect is an agent published in the GitHub repository cloudnative-co/claude-code-starter-kit (153 stars, last pushed 5d ago), licensed MIT. It adds 33 tokens to every session and 244 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
