create-db-design is a command for GitHub Copilot from ChenyCHENYU/wl-skills-design. It costs 18 tokens per session (212 once invoked), scanned A, original, Apache-2.0.

A database-design command that creates an entity-relationship diagram, data dictionary, indexes, and SQL table definitions from a confirmed database profile. An entity-relationship diagram shows data objects and how they relate.

In plain words
What is it for?
It helps define entities, fields, keys, tenants, deletion and audit rules, concurrency handling, indexes, and database-specific SQL, then checks the new design.
Why use it?
It makes database decisions explicit before generating SQL and marks unknown choices as pending instead of guessing.

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

create-db-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 11d 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.
