Install & config
Client config (built from the install command this repo gives)
{
"mcpServers": {
"boranfurkan-typescript-7-migration": {
"command": "npx",
"args": ["skills"]
}
}
}Parsed from the README we fetched on 2026-11-02; we have not executed it.
command/args come from the install command the repository states. When it is ambiguous, the project README wins.
VS Code (.vscode/mcp.json - the key is servers)
{
"servers": {
"boranfurkan-typescript-7-migration": {
"command": "npx",
"args": ["skills"]
}
}
}Same server, but VS Code keeps it under <code>servers</code>.
Claude Code (command line)
claude mcp add --transport stdio boranfurkan-typescript-7-migration -- npx skills
Claude Code does not read a config file; add the server with this command.

Lets your coding agent upgrade projects to TypeScript 7 correctly, using facts from the official release notes
instead of guesses.
Works with Claude Code, Codex, Cursor, Gemini CLI and any agent that reads Agent Skills (SKILL.md).
TypeScript 7.0 (July 2026) is the Go-native compiler: about 10× faster type-checking. It shipped after the training
cutoff of today's models. They know the general direction (6.0 deprecations, "native port") but hedge or guess on
the details that decide whether your upgrade works:
7.0 has no compiler API. typescript-eslint, vue-tsc/Volar, ts-node, ts-jest, ts-patch transformers and any
script using ts.createProgram must stay on 6.0, via the official @typescript/typescript6 package.
Hard errors: target: es5, downlevelIteration, moduleResolution: node, baseUrl,
esModuleInterop: false, outFile, AMD/UMD/System modules, and more.
Silent default changes: types is now [] ("Cannot find name 'describe'") and rootDir is the tsconfig's
directory (output moves to dist/src/).
How to run 6.0 and 7.0 side by side with npm aliases.
### Eval results
Graders passed (LLM judge = Sonnet, 3 votes per grader), 2 runs per arm, one table cell per run.
| Case | Sonnet without | Sonnet with | Haiku without | Haiku with |
| ts7-tooling-migration-plan (3 graders) | 0/3, 0/3 | 3/3, 3/3 | 0/3, 0/3 | 2/3, 2/3 |
| upgrade-node-service-to-ts7 (4 graders) | 3/4, 4/4 | 4/4, 4/4 | 2/4, 2/4 | 3/4, 4/4 |
| ts7-post-upgrade-breakage (2 graders) | 1/2, 2/2 | 2/2, 1/2 | 2/2, 1/2 | 2/2, 2/2 |
| Total | 10/18 | 17/18 | 7/18 | 15/18 |
## Read this before trusting the numbers
Small samples: 2 runs per arm per case. Differences of a point or two are noise.
Offline agents: the agents had no web tools. Real agents with web access may find these facts themselves, so real-world gains are likely smaller.
Same author: the skill and the graders were written by the same person from the same release notes.
One mechanism-specific grader: it requires the @typescript/typescript6 side-by-side mechanism specifically.
Strict graders: the two with-skill misses are judged strictness, not wrong answers. Haiku tooling grader 1 bundles "no API in 7.0", "new API in 7.1" and "ts-patch can't run" into one check; both answers got the substance right but omitted the 7.1 mention. Sonnet post-upgrade run 2 explained the types default and fixed it, but split node/jest across two tsconfigs, and the judge voted 1-2.
Skill edited mid-evaluation: after the first Haiku with-skill runs I added a line to SKILL.md telling the agent to state the "7.0 has no compiler API" reason explicitly, then re-ran Haiku on the tooling and upgrade cases. Scores did not improve (tooling 2/3, 2/3 again; upgrade 4/4, 3/4), so the table keeps the original runs. The Sonnet runs used the earlier SKILL.md wording.
Facts date: as of TypeScript 7.0, re-checked 2026-11-02 (7.1 was still in beta).
The same author also made a benchmark of a data-analysis skill where gains were much smaller.
