Overview

Research summary

Spec Kitty turns product intent into a repository-native pipeline: spec → plan → tasks → next → review → accept → merge. Mission artifacts retain specifications, plans, acceptance criteria and work-package state as the source of truth. Work packages can be dispatched to different coding agents inside isolated Git worktrees, allowing parallel implementation while reducing branch interference.

Explicit review, acceptance and merge gates keep humans in control, and a local dashboard exposes work-package progress. Integrations support major coding agents through skills or slash commands. The maintainers position it as infrastructure for a governed software factory rather than an opaque autonomous black box.

Stable releases remain on the 3.x line while main is qualifying 4.x release candidates; the catalog records the latest stable release. The Python code is MIT-licensed.
