What it does

Lunora Migration Helper is an agent skill from anolilab/lunora. Plans and runs Lunora schema and data migrations with the widen → migrate → narrow pattern. Covers online data migrations (defineMigration in lunora/migrations.ts, lunora migrate create | up | down | status), what the pre-deploy schema-drift gate treats as breaking and how a migration covers it, .global() table DDL on D1 (lunora migrate generate) and Hyperdrive, moving a dataset with lunora migrate d1-to-hyperdrive, and re-keying a .shardBy() table. Use when the user wants to make a field required, rename or drop…

Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases. It works with SQL. The repository describes itself as: Type-safe, real-time backend framework on your own Cloudflare account — Workers, Durable Objects, D1, R2, Queues. Convex-style DX, Vite-first.

When your agent uses it

  • The user wants to make a field required
  • Change a fields type
  • Add a unique index to a populated table
  • Switch a table between root / .shardBy() / .global()

Example prompts

  • “schema drift gate blocked”
  • “Use the lunora-migration-helper skill to plan and runs Lunora schema and data migrations with the widen → migrate → narrow pattern”
  • “/lunora-migration-helper”

Requirements

  • A credential in LUNORA_ADMIN_TOKEN

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Widen. Make the schema accept both shapes: add the new field as
  2. Migrate. Backfill existing rows with a defineMigration, run it with
  3. Narrow. Make the field required / drop the old one, remove the

What it can do on your machine

Read from SKILL.md and the folder at commit 3650b5e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • wrangler

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use wrangler, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • LUNORA_ADMIN_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Lunora Migration Helper loads about 2.6k tokens when it runs. Until then it costs about 193 tokens; SKILL.md has 1,111 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~193
When it runs · the whole SKILL.md, loaded when a task matches
~2.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,111 words (~2,622 tokens).

“Change a Lunora schema that already has data in it without breaking the deploy or losing rows.”
