migrate

migrate is a skill for Claude Code from get-convex/convex-backend-skill. It costs 59 tokens per session (237 once invoked), scanned A, original, no licence file.

A migration process for changing the database structure and updating existing records in a deployed Convex app. A backfill means filling or converting data already stored in the database.

In plain words
What is it for?
Use it when changing a live Convex schema or backfilling existing data; it is not intended for a fresh local app.
Why use it?
It helps apply schema changes safely when the app is live and existing data must still fit the new structure. It also addresses schema-validation errors caused by changes.

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

migrate 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 6d 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.
