Vibeweaver
A skill that enforces a strict process on a coding agent, such as decomposing a request, searching for prior art, designing before writing code, and verifying against runtime evidence, stopping the agent and making it start over when it drifts.
Vibeweaver is a skill, tuned mainly for opencode though meant to run on any agent harness, that does not try to make a model more capable; instead it tries to make the capability a model already has actually count, by enforcing a process: decompose the request, search for prior art, choose between at least two approaches, design before writing code, test first, verify against runtime evidence, and review before shipping.
The project's own published benchmarks show both directions: on the weakest model in its test set the full skill made results worse, because the model could not reliably follow the added process and the extra context made drift worse, while a more capable model reached a top score once the discipline was enforced. Enforcement is not just a prompt; a gate plugin and an auditor plugin watch the session and the files on disk for a missing required artifact.
