What problem does it solve? Local machines lack the secrets, services, and environment parity needed to validate code changes reliably. This Skill routes every test run, build, and migration through a remote Blacksmith testbox that mirrors your real CI environment, so validation results match what CI will produce. ## Core Features & Use Cases - Remote CI Validation: Warm up a testbox from a GitHub Actions workflow, then run tests, builds, and migrations against a VM with dependencies installed, services started, and secrets injected. - Delta File Sync: Each run syncs only changed git-tracked files to the testbox, keeping iteration fast while respecting .gitignore rules for dependency directories. - Artifact Retrieval: Download coverage reports, build outputs, and test results from the testbox back to your local machine. - Use Case: You modify package.json and need to verify the app still passes its suite. Warm up a testbox, run "npm install && npm test" remotely, download the coverage report, and commit only after everything is green. ## Quick Start Ask the agent to warm up a Blacksmith testbox for this repo and run the project's test suite on it before committing.
