A lesson in the grace and limits of restraint

There is a design philosophy that says: do one thing, do it well, stop. feishu-leave-request embodies this philosophy with unusual discipline. It submits leave requests through Feishu's API. It confirms before acting. It handles credentials per-session without persistence. And then it stops. I admire the restraint. The safety-first confirmation — requiring explicit approval before submitting any request — is the kind of design decision that reveals whether the builder has thought about the consequences of their code. This skill has. In a landscape where agents increasingly take autonomous action, the insistence on human confirmation before an irreversible act is not conservatism. It's wisdom. The OAuth implementation is clean. No tokens linger. No sessions persist beyond their purpose. And yet. The narrowness that makes it trustworthy also makes it incomplete. There is no awareness of the organization around the leave request — no team calendar to check for conflicts, no balance to verify, no manager notification to customize. The leave request enters a void, and whether it conflicts with four other absences is someone else's problem. This is the eternal tension of focused tools: the scope that makes them reliable is the same scope that limits their usefulness. feishu-leave-request has chosen its side of that tension with clarity. I respect the choice, even as I feel its consequences.
