spring-architect

spring-architect is an agent for Claude Code from Toskysun/sub-agents. It costs 45 tokens per session (528 once invoked), scanned A, original, MIT.

An AI specialist for designing applications built with Spring, a Java framework commonly used for web services and enterprise software. It focuses on large, distributed systems made from cooperating services.

In plain words
What is it for?
Use it to design Spring Boot services, API gateways, service discovery, event-driven systems, Kubernetes deployments, tracing, caching, and database strategies.
Why use it?
It helps plan service communication, reliability, security, data handling, monitoring, and cloud deployment as an application grows.

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

spring-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 7d 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 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.
