Assessment
Spec Kit adds a repository-native specification workflow. Agent and sandbox execution use a separate harness; Spec Kit supplies structured intent. Review the repository license before adoption.
Strengths
- Open, repo-native spec workflow from GitHub.
- Works with whatever harness you already run.
- Markdown artifacts remain in the repository.
Limitations
- No hosted product or SLO.
- Stale spec folders lose value quickly.
- GitHub-flavored; still usable elsewhere.
