# Minimal 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 1. **Reproduce** — Write the user's code to `packages/samples/scratch/main.tsp`, compile with `npx tsp compile main.tsp` (add `--emit <emitter>` if relevant), and confirm the same error occurs. 2. **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. 3. **Present** — Show the final minimal `.tsp`, the compile command, and the error output. Suggest pasting into a GitHub issue or the [TypeSpec Playground](https://typespec.io/playground). 4. **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`, `@info` early — they're rarely relevant. - Combine multi-file code into one file by inlining. - If the error doesn't reproduce, check for missing `import`/`using` statements.
