validate-type-safety SKILL.md skillA
validate-type-safety from coalesce-labs/catalyst is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add coalesce-labs/catalyst/validate-type-safety@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Run the full 5-step TypeScript validation gate: type check, reward hacking scan, test inclusion, tests, and lint. This skill provides a structured multi-step pipeline that you cannot replicate on your own — it detects the project's package manager and linter automatically, checks tsconfig strictness, and invokes /scan-reward-hacking internally. **ALWAYS consult this skill when** the user mentions 'validate types', 'check type safety', 'type validation', 'type safety gate', wants to verify…
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
# Validate Type Safety
Final verification gate before marking any TypeScript work complete. Combines type checking with reward hacking detection, test verification, and linting. ALL 5 steps must pass.
## Tooling Detection
Before running any commands, detect the project's package manager and linting tool. Do NOT hardcode `bun`, `npm`, or `trunk` — detect from what's available.
### Package Manager
Check for lockfiles in the project root:
| Lockfile | Package Manager | Run Command |
|----------|----------------|-------------|
| `bun.lockb` or `bun.lock` | bun | `bun run` |
| `pnpm-lock.yaml` | pnpm | `pnpm run` |
| `yarn.lock` | yarn | `yarn run` |
| `package-lock.json` | npm | `npm run` |
If multiple exist, prefer in the order listed above. Store as `$PM_RUN` (e.g., `bun run`).
### Linter
Check for linting tools in this order:
| Check | Linter | Command |
|-------|--------|---------|
| `.trunk/` directory exists | Trunk | `trunk check --ci --upstream origin/main` |
| `biome.json` or `biome.jsonc` exists | Biome | `${PM_RUN} biome check .` |
| `eslint.config.*` or `.eslintrc.*` exists | ESLint | `${PM_RUN} eslint .` |
If none found, skip Step 5 and note it in the output.

How to install
mdr add coalesce-labs/catalyst/validate-type-safety@sha256:5a450c6248fa3fd5The line at the top of this page pins the label v1.0.0, 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.
