npx skills add https://github.com/microsoft/typespec --skill minimal-reproMinimal Reproduction
Reduce a user-reported TypeSpec bug to the smallest single .tsp file that still triggers the issue.
Inputs
- TypeSpec source (pasted or GitHub URL)
- Error description (diagnostic code, message, or incorrect emitter output)
Environment
Use packages/samples/scratch/ as the working directory — it's gitignored and the packages/samples package already depends on compiler, http, rest, openapi3, versioning, json-schema, etc.
If the repro needs packages NOT in the workspace (e.g., @azure-tools/*), use a temp folder with npm install instead.
Steps
-
Reproduce — Write the user's code to
packages/samples/scratch/main.tsp, compile withnpx tsp compile main.tsp(add--emit <emitter>if relevant), and confirm the same error occurs. -
Minimize — Iteratively remove code (unused imports, models, properties, decorators, operations, namespaces) and re-compile after each removal. Keep only what's needed to trigger the same error. Undo any removal that makes the error disappear.
-
Present — Show the final minimal
.tsp, the compile command, and the error output. Suggest pasting into a GitHub issue or the TypeSpec Playground. -
Cleanup — Remove scratch files (
rm -f packages/samples/scratch/*.tsp packages/samples/scratch/tspconfig.yaml && rm -rf packages/samples/scratch/tsp-output).
Tips
- Most reproductions reduce to a single file with no namespaces needed.
- Remove
@service,@server,@doc,@infoearly — they're rarely relevant. - Combine multi-file code into one file by inlining.
- If the error doesn't reproduce, check for missing
import/usingstatements.
