The packet factory is the gatekeeper between intent and execution. Nothing with a side effect runs without an APPROVED packet.
bash# Create a new packet (DRAFT status) skills/packet-factory/new-packet.sh \ --intent "Post daily update to Slack #arc-angels" \ --source "Ludo DM 2026-04-01 09:00" \ --destination "Slack #arc-angels" # Review a packet (set APPROVED or REJECTED) skills/packet-factory/review-packet.sh --id 2026-04-01-001 # Dispatch an APPROVED packet (executes and logs output) skills/packet-factory/dispatch-packet.sh --id 2026-04-01-001
All in-flight packets live in memory/packet-queue.md.
The heartbeat pre-flight check reads this file. DRAFT packets older than 24h are escalated to Ludo.
Once a packet is APPROVED, scope_locked_at is set and the scope field is frozen.
If the task grows (new deliverable discovered, Ludo asks for something extra), the current packet is dispatched as-is and a new packet is created for the expansion. Never mutate an approved packet's intent or output.
This prevents the single most common failure mode: scope creep → context balloon → session death.
