Spec Kit - 0.9.0

Install

uv tool install specify-cli --from git+https://github.com/github/spec-kit.git@v0.9.0
specify init my-project

Notice

We have migrated agent context updates to the agent-context extension and currently auto-enable it to preserve existing behavior. This compatibility fallback is deprecated and will be removed in v0.12.0; after that, explicitly enable/configure agent-context to continue automatic context updates.
