migrate-objects-auto

migrate-objects-auto is a skill for Claude Code from sfc-gh-dflippo/snowflake-dbt-demo. It costs 70 tokens per session (7,023 once invoked), scanned A, original, Apache-2.0.

An unattended migration workflow that assigns each ready group of database objects to its own helper and keeps starting more as helpers finish.

In plain words
What is it for?
It helps run large migrations in parallel, taking objects through conversion, deployment, testing, and fixes.
Why use it?
It removes the need to supervise every object one at a time. It pauses only when work is blocked, a dependency needs a decision, or data is about to move.

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-objects-auto 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 527 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Migrate Objects — Autonomous

On Entry IMPORTANT DO NOT SKIP

Tell the user:

Autonomous mode. I'll work the wave by giving each object its own subagent, which walks it the whole way — convert, deploy, tests, fixes — and I'll refill as they finish. I'll interrupt you only when an agent is stuck, when a dependency needs a human decision, and before any data moves. Say "stop" at any point and I'll let in-flight work land.

Step 0: Preflight

  1. configure(project_dir=<project dir>, subagent_mode=true, snowflake_connection=<the configure connection the first prompt named>). Read the appended migration-status block. Bring the shared data infrastructure up: data_infrastructure(mode="up"). Relay its cost_reminder. status="not_ready" is not a green light — a first local bring-up runs every schema migration and can need more than one call, so follow its remediation and call up again until it reports ready. Once means one successful bring-up for the wave, not one call.
  2. If configure() reports setup is not finished, read ../../setup/SKILL.md then come back here.

subagent_mode attributes writes per Cortex conversation. Set it once here; it lasts the life of the server and cannot be turned off. Cortex stamps identity on every MCP call — do not pass agent_id. The parent hook injects 0000 while this latch is on: park a looping object, reset a remediated transient failure, and relay non-terminal guidance. Acknowledge unreviewed notes only in Step 3 (review), never in the dispatch loop. Object-level outcomes stay parked for a person in an interactive session. deploy, migrate_data, and validate_data are not binding-checked — keep each agent on its own object.

Step 1: Ask how many subagents to run at once

Offer 2 / 4 / 6, recommend 4. State the trade-off: more slots finish the wave faster, burn proportionally more tokens, and produce more escalations competing for their attention. Call it N. Never exceed it, and never quietly raise it.

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.
