codegen

Run one command:

set -o pipefail; cd web && npm run codegen --silent 2>&1 | cut -c1-300 | tail -30

It builds the API quietly into bin/codegen/ (works while Aspire is running, no locked-DLL errors), which regenerates openapi/Skoleoverblikket.Api.json, then runs openapi-ts with --silent. Success prints about five lines ending in 0 Error(s). On failure, report the error lines verbatim and fix the C# compile error they name.

Done means exit code 0. Then move on. To prove the client still fits the pages that use it, run npx tsc -b in web/ (or /verify).

Never read, grep or diff the generated output

These files are generated and huge. Reading them only costs tokens:

File	Size
openapi/Skoleoverblikket.Api.json	~400 KB
web/src/api/generated/*.gen.ts	barrel lines of 12,000–15,000 chars

One grep match on a barrel line dumps ~7k tokens. A Read dumps far more. The repo-root .ignore already hides both paths from repo-wide Grep/Glob. Don't get around it by passing the paths explicitly.

• Don't Read them, cat them or open them to "check the output".
• Don't run git diff on them. Use git diff --stat or exclude them: git diff -- . ':!openapi' ':!web/src/api/generated'.
• To find a hook or type name, grep the usages in web/src/pages and web/src/components. Names follow {method}ApiV1{Path}, for example getApiV1StaffAbsencesOptions and postApiV1StaffAbsencesMutation.

If you really must confirm a symbol exists, count it or truncate every line:

grep -c "MySymbol" web/src/api/generated/@tanstack/react-query.gen.ts
grep -n "MySymbol" web/src/api/generated/sdk.gen.ts | cut -c1-120 | head -5
