explain-project-design

explain-project-design is a skill for Claude Code, Codex from ttxttx1111/sts2-llm. It costs 31 tokens per session (234 once invoked), scanned A, original, MIT.

A guide to explaining the design history of a multi-agent Slay the Spire 2 project. A multi-agent system divides work among several cooperating software agents.

In plain words
What is it for?
Use it to present the project's architecture, explain why the first live approach underperformed, describe the newer design, and distinguish active assets from archived ones.
Why use it?
It gives reviewers and teammates a clear account of the older coordinator-heavy design, the newer standalone bridge, and the responsibilities of each part.

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

explain-project-design 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 it actually says

讲清项目设计

适用场景:向评审、同事、面试官介绍这个仓库。

需要覆盖

  1. V1:coordinator-heavy 多智能体 runtime
  2. V2:standalone-bridge runtime
  3. player / runtime / reviewer 的职责边界
  4. 为什么第一版 live 路径效果一般
  5. 为什么第二版 bridge 设计更强
  6. .github 标准 Copilot 资产和 archive/legacy-runtime-assets/ 的区别
  7. 为什么这个项目仍然值得写进简历

约束

  • 同时讲清架构故事和真实 live 运维故事。
  • 不要把归档的 legacy runtime 资产说成当前活动的标准 Copilot skill。
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.
