[agent] Failed to update typescript

[claude]

Failed dependency update

Package: typescript
From: 6.0.3 → To: 7.0.2

Error

pnpm update-outdated-deps bumped typescript to 7.0.2 in the root and in all 34 workspace package.json files. Every eslint task in the repo then crashed before linting a single file — first in the update script's own update-outdated-deps:fix-pkg-json step, then in Step 2a (pnpm lint), where all 35 eslint tasks failed with exit code 2:

ESLint: 9.39.2

TypeError: Cannot read properties of undefined (reading 'Cjs')
    at node_modules/.pnpm/@typescript-eslint+typescript-estree@8.54.0_typescript@7.0.2/node_modules/@typescript-eslint/typescript-estree/dist/create-program/shared.js:59:14
    ...
    at async eslint.config.ts:1:218

Root cause

typescript-eslint is deliberately excluded from updates by the update-outdated-deps:update-versions script:

pnpm update -r --latest !eslint !@eslint/js !typescript-eslint !useless-lib

so it stays pinned at 8.54.0, whose @typescript-eslint/typescript-estree reads a ts.Extension/ModuleKind member (Cjs) that no longer exists in TypeScript 7. @typescript-eslint/parser is not in the exclusion list, so it was bumped to 8.68.0 independently — leaving the parser and the plugin/estree on different versions as well.

What was tried

1. Reverted only the root typescript to 6.0.3 and reinstalled — eslint still crashed, because the other 33 workspace package.json files still declared 7.0.2.
2. Reset the working tree and re-ran the update with typescript added to the exclusion list:

   pnpm update -r --latest '!eslint' '!@eslint/js' '!typescript-eslint' '!useless-lib' '!typescript'
   

   followed by syncpack fix, pnpm install --no-frozen-lockfile and update-outdated-deps:fix-pkg-json. All four validation steps then passed.

No clean migration is available from the agent's side: adopting TypeScript 7 requires unpinning typescript-eslint (and aligning it with @typescript-eslint/parser), which is a deliberate repository decision rather than a dependency bump.

Suggested follow-up

• Move typescript-eslint to a release that supports TypeScript 7, together with @typescript-eslint/parser and @workleap/eslint-configs, then bump typescript to 7.x.
• Consider adding @typescript-eslint/parser to the same exclusion list as typescript-eslint (or removing both), so the parser and the plugin cannot drift apart on future runs.
