output-migrate

output-migrate is a skill for Claude Code from growthxai/output. It costs 69 tokens per session (1,781 once invoked), scanned A, original, Apache-2.0.

A migration guide for Output.ai projects, a framework for building multi-step AI workflows. It identifies the current framework version, retrieves the matching upgrade instructions, applies them, and checks the project’s types.

In plain words
What is it for?
Use it when upgrading Output.ai packages, moving to a newer version, or applying several breaking-change migrations in sequence.
Why use it?
It helps handle changes between framework versions without guessing which updates are required. It also checks for type errors after the migration.

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

output-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 8d 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.

Migrate an Output Project

Overview

This skill migrates a project from one version of the Output framework to another.

You do not carry migration instructions in your own context. The docs site at https://docs.output.ai/migrations is the source of truth — fetch the right page and follow it.

Use the todo tool to track your progress.

When to Use This Skill

  • The user wants to upgrade @outputai/* packages to a newer version
  • The user mentions "migrate", "upgrade", or "move to vX.Y.Z"
  • A breaking-change release shipped and the user is still on an older version

URL contract

Migration guides are hand-authored MDX pages linked from a single index:

  • Index: https://docs.output.ai/migrations
  • Per-boundary guide: https://docs.output.ai/migrations/v{FROM_FULL}-to-v{TO_FULL} (e.g. v0.1.12-to-v0.2.0)

The index lists every available guide with a title and a short description. A release only has a guide if it introduced breaking changes — most releases will not have one.

If the user is jumping multiple boundaries, fetch each applicable guide in order and apply them sequentially.

Instructions

<process_flow>

Step 0: Arguments Analysis

If the user passed arguments when invoking this skill, parse them as positional values in this order (all optional):

  • from-version: The version the project is currently on. If blank, detect it in Step 2.
  • to-version: The target version. If blank, resolve it in Step 1.
  • additional-instructions: Free-form guidance from the user (e.g. "skip the http changes, we don't use that package").

Step 1: Determine the target (TO) version

If the user provided a to-version argument, use it.

Otherwise, run npm view @outputai/core version via Bash and use that as the target.

Step 2: Detect the current (FROM) version

If the user provided a from-version argument, use it and skip the rest of this step.

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.
