Reviewer notes

Source Reviewed review. These are observations, not a security certification.

67 stars, Apache 2.0 license, 6 architecture patterns documented with validation and dry-run phases. Lower reliability (3) because relatively new tool (67 stars) with limited production track record. Well-structured with explicit validation steps. Client readiness tier-2 because outputs require technical evaluation.

Apache 2.0 license. Pure SKILL.md + reference docs with no external dependencies or runtime code. Generates .claude/agents/ and .claude/skills/ files locally — no network calls. Individual developer maintainer.

2026-04-02: LIMITATION: Generates agent topology blueprints but doesn't validate that generated agents actually work. Outputs require hands-on testing before production use.
