To enforce physical confirmation for irreversible MCP tool actions, you need a fail-closed discipline that requires a physical device confirm before proceeding and aborts on cancel, timeout, or unavailability. This Skill applies that exact safety guardrail to Cardputer MCP interactions.

Fail-closed device etiquette for BLE handheld alerts is a runtime policy that mandates physical confirmation for destructive operations and suppresses non-critical chatter. It ensures potentially irreversible agent actions are safely blocked if the pocket device is unavailable or times out.

To format MCP notification messages for a 240x135 LCD display, keep titles and message bodies compact for fast glance readability. This Skill provides LCD-constrained formatting heuristics to ensure agent-driven alerts remain readable on the small Cardputer screen.

An AI agent should use the ask tool for a blocked decision only when the user may be away from the keyboard and needs to provide input. This Skill enforces smart asking behavior by limiting questions to short choice-style formats during genuine blockages.

Yes, this MCP safety guardrail respects Do Not Disturb policies by avoiding non-critical device chatter while still keeping destructive operation confirmations fail-closed. It ensures quiet completion notifications are sent only for genuinely long-running tasks requiring attention.

If the Cardputer device is unavailable during a force push confirmation, the fail-closed protocol aborts the irreversible operation. This Skill prevents unsafe agent interactions by ensuring destructive actions cannot proceed without a successful physical confirm response.
