check SKILL.md skillB
check from vibiumdev/vibium is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vibiumdev/vibium/check@git:20260923.6107c69Pins git:20260923.6107c69 in mdr.lock. Pin the fingerprint instead.

Independently check application acceptance criteria in a live browser or saved recording with the Vibium CLI. Use for a formal verification step in the development loop, with PASS, FAIL, or INCONCLUSIVE and recorded evidence.
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
# Check with Vibium Use `vibium check "<claim>"` to hand a specific acceptance claim to a fresh verifier context. The coding agent builds and fixes the application; Vibium's verifier investigates the running behavior with constrained browser tools. Your own browser inspection does not substitute for this invocation. ## Setup Use the project's configured Vibium binary. Otherwise try `vibium`, `./clicker/bin/vibium`, then `./node_modules/.bin/vibium`. Confirm `vibium check --help` works. Local Chrome is the tested baseline for live checks. For initial live setup, run `vibium ready browser --json` with the selected engine/channel. It inspects browser and driver files without launching them or touching the current browser; launch and BiDi connectivity remain untested. Follow its install/fix guidance if needed. Saved-input checks do not require a browser; skip browser readiness for them. For OpenAI, export `VIBIUM_AI_PROVIDER=openai`, `VIBIUM_AI_MODEL`, and `OPENAI_API_KEY`. For xAI, select `xai` and export `XAI_API_KEY` (for example `--model grok-4`). For Anthropic, select `anthropic` and export `ANTHROPIC_API_KEY`; for Google, …

How to install
mdr add vibiumdev/vibium/check@sha256:e65533527150ac3aThe line at the top of this page pins the label git:20260923.6107c69, 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.
