Fix TypeScript errors with strict anti-reward-hacking rules. **ALWAYS use when** the user says 'fix type errors', 'fix typescript', 'type-check is failing', or when TypeScript compilation errors need to be resolved. Ensures runtime type safety — fixes root causes instead of silencing errors with casts.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fix TypeScript Errors Fix TypeScript type errors for **runtime type safety**, not just to satisfy the linter. If a fix would pass `tsc` but could still crash at runtime, it's wrong. ## Forbidden patterns The canonical, exhaustive forbidden-pattern table — `as any`, `as unknown as`, `@ts-ignore` / `@ts-expect-error`, void tricks, underscore-prefixed unused locals, non-null assertions without a guard, `forEach(async`, and exported unused types, each with severity and acceptable/unacceptable examples — lives in the `/catalyst-dev:scan-reward-hacking` skill. Run it before marking this work complete; don't re-derive the list here. Two more rules are process-level, not grep-able code patterns, so `/catalyst-dev:scan-reward-hacking` doesn't scan for them — they are still forbidden: - **Commenting out code** instead of deleting it (git has history). - **Excluding files from `tsconfig`** to hide errors instead of fixing them. ## Stricter than the canonical scan …

How to install
mdr add coalesce-labs/catalyst/fix-typescript@sha256:ffcebaf6587d9ba2The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
