TypeScript version migration guide (5.x to 6 to 7, tsgo native port). Use for TS 6 tsconfig breaking changes, TS 7 Go rewrite rollout, or TS5xxx deprecation codes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TypeScript Migration
Authoritative migration guide for TypeScript 5.x → 6 → 7 (native Go port). Sourced from Microsoft's official announcements.
## Status
- **Skill Status**: Production Ready
- **Last Updated**: 2026-07-09
- **TS 6.0 Released**: 2026-03-17 (Final) — last JavaScript-based release
- **TS 7.0 Released**: 2026-07-08 — native Go port ("Corsa"), stable
- **Authoritative Sources**:
- TS 7.0 release: https://devblogs.microsoft.com/typescript/announcing-typescript-7-0/
- TS 6.0 beta: https://devblogs.microsoft.com/typescript/announcing-typescript-6-0-beta/
- TS 6 → 7 diff tracker: https://github.com/microsoft/typescript-go/blob/main/CHANGES.md
- ts5to6 tool: https://github.com/andrewbranch/ts5to6
## The Golden Rule
> NEVER skip TypeScript 6. The only supported paths are **5.x → 6 → 7**.
>
> Skipping TS 6 produces a wall of hard errors because TS 7 removes everything TS 6 deprecated. Use `"ignoreDeprecations": "6.0"` only as a temporary pause inside TS 6; it does NOT work in TS 7.
## Quick Triage (1 Minute)
1. **Detect current version** — run `scripts/detect-ts-version.sh` (reads `package.json`).
2. **Classify the path**:
…Read the whole file at its exact version.
How to install
mdr add secondsky/claude-skills/typescript-migration@sha256:0f2f51c37efdcf76The line at the top of this page pins the label git:20260718.07ff1fc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
