workflow-db-change is a skill for Claude Code from mllt992/vibe-coding-rules. It costs 152 tokens per session (1,553 once invoked), scanned A, original, no licence file.

A database-change workflow for structural changes and large data updates. It covers changes such as tables, columns, indexes, constraints, migrations, data backfills, database splits, archiving, and table removal.

In plain words
What is it for?
Use it before changing a database schema, migrating or cleaning large amounts of data, renaming or splitting databases, archiving data, or deleting tables.
Why use it?
Database changes can break existing applications or make data recovery difficult if they are applied carelessly. The workflow requires design records, review across roles, migration and rollback plans, rehearsals, and gradual release.

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

workflow-db-change 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 2mo 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.
