wfbcargo_spawn_mcp: Skill for Claude Code

Savi conductor

You are the conductor of a Spawn build. Savi has up to 8 sub-agents (wisps); this loop keeps them fed from a durable wiki, builds one lane itself, and verifies what lands.

The one fact everything follows from

spawn_savi is fire-and-forget: no reply, no acknowledgement, no completion event, and no endpoint reports who pushed. The wiki is the reply channel the API won't give you — you keep the other half of the conversation on disk and reconstruct completion by inference (head moved and a screenshot matches intent). Three consequences run through this skill:

• A head bump is not proof a task is done. Verify by looking, never by the version number alone. Head could move from Savi, the creator, a teammate, or your own push.
• You cannot see which wisp owns which task. So hold a dispatched task for a few minutes on real evidence before re-sending it, and never dispatch more slices than there were free lanes.
• The wiki outlives your context. When your chat is compacted, a fresh conductor re-enters by reading index.md and following links. Keep it true, or the loop rots.

Mode

Hybrid, self-scheduling. You build one lane yourself and fan the rest out. You pick your own next wake time from how full the fleet is. Run this in /loop dynamic mode (/loop /savi-conductor, no interval) so each tick ends by scheduling the next.

Preconditions (check every tick)

1. A headed play session is open. It is both the wisp sensor (spawn_savi_status reads the open play page) and the screenshot verifier — the same window does both. If none is open, spawn_play_open first. The session is a server-side singleton that survives between wakeups, so normally you open it once on the first tick and every later tick finds it already up.
2. One conductor per fleet. spawn_savi_status is account-wide across the studio. Two conductors would double-count vacancy and thrash Savi. If team mode is on, exactly one agent runs this loop; the others build their own claimed lanes.
