Skill Claude CodeCodex
Review code changes for bugs and alignment with OpenEnv principles and RFCs. Use when reviewing PRs, checking code before commit, or when asked to review changes. Implements two-tier review model.
Skill Claude CodeCodex
Deploy an OpenEnv environment to Hugging Face Spaces. Use when asked to deploy, push to Hugging Face, or update a space.
Skill Claude CodeCodex
Generate OpenEnv environments from a concrete use case (for example, "generate an env for the library textarena"). Use when asked to design or implement a new environment under envs/ by researching a target library/API, selecting matching OpenEnv examples, asking key implementation questions, and building…
Skill Claude CodeCodex
Diagnose and recover failing or stuck Hugging Face Space deployments for OpenEnv environments. Use when deploying envs from envs/ to the Hub (openenv namespace with version suffixes), when Spaces are in BUILDING/APPSTARTING/RUNTIMEERROR, or when release collections need to be reconciled after targeted redeploys.
Skill Claude CodeCodex
Make tests pass. Invoke after /write-tests produces failing tests.
