design-template

design-template is a skill for Claude Code, Codex from frankekn/three-kingdoms-kiro. It costs 37 tokens per session (337 once invoked), scanned A, original, MIT.

A template for technical design documents that explain a proposed system, its data, APIs, file changes, error handling, and tests. It can also describe flows with Mermaid diagrams, a text format for technical diagrams.

In plain words
What is it for?
Use it for architecture plans, API designs, data models, sequence diagrams, file-structure proposals, error strategies, and test plans.
Why use it?
It gives developers a shared plan before implementation and makes important boundaries, assumptions, and limitations easier to review.

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-template 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 9d 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.
