Beacon's angle is a shared, owned memory layer: capture sessions across harnesses, keep them local-first, and serve the accumulated knowledge back to any of them over MCP or Agent Skills. For a team building agent-driven internal tooling, that cross-harness, owned memory is the difference between per-tool amnesia and a shared knowledge base. The honest read: 1,493 stars and active releases make this the most-validated tool in this batch, but the specific claim that it grades runs into reusable skills is the tool's own and unproven — and it surfaced via a viral tweet whose hype hook the repo does not back up. Adopt it for the shared-memory mechanics; verify the \"reusable skills\" quality yourself."
