GPT Retirement Rescue Kit
A plain prompt can rewrite your GPT's instructions; this kit also inventories what migration silently drops, turns each Action into an MCP plan with a secrets-safe credentials path, and proves the replacement behaves the same with a before/after diff.
For: People with custom GPTs to move before retirement, and consultants migrating GPTs for clients.
Why now: OpenAI's FAQ says custom GPTs retire Dec 11, 2026 and new GPT creation ends Oct 26, 2026 (subject to change, per OpenAI's FAQ).

What's inside
- Inventory: reads your GPT details and lists blockers (secrets pasted in instructions, unpublished drafts, missing Action schemas, missing files) and everything that won't transfer
- Action rebuild: OpenAPI schema to MCP tool plan, read vs write tools, approval settings, and a credentials path that keeps secret values out of chat and files
- Claude skill draft: GPT to Claude skill folder, linted against Anthropic's published rules
- Parity harness: same prompts before and after, checking facts, format, forbidden behaviour and tool calls; verdict SWITCH OK or DO NOT SWITCH YET
- Instruction hardening and a target picker (plugin, Claude skill, both)
What it won't do
- Click Migrate, publish, share, upload or email anyone without your approval
- Host your MCP server or store your secrets
- Promise identical behaviour. It measures the difference instead
- Work inside ChatGPT or Claude by itself. You paste outputs from them into the harness
