@@ -20,6 +20,7 @@ Package metadata lives in [prpm.json](prpm.json). The repo currently publishes `
 | [daily-digest](skills/daily-digest/SKILL.md) | 1.0.0 | Authoring contract for `<mount>/digests/` files — windows, per-provider sections, adapter `digest()` exports, regeneration rules. |
 | [writeback-as-files](skills/writeback-as-files/SKILL.md) | 1.0.0 | File-creation writeback contract — drop a JSON file at the canonical path and relayfile delivers the mutation, with dead-letter recovery. |
 | [workspace-layout](skills/workspace-layout/SKILL.md) | 1.0.1 | Navigate a relayfile mount via root and per-provider `LAYOUT.md` files plus `by-*` alias indexes instead of `find`/`grep -r`. |
+| [multi-host-live-mount](skills/multi-host-live-mount/SKILL.md) | 1.0.0 | Mount one workspace on many hosts and place an agent in a live-mounted tree with nothing cloned — join, per-node scopes and credentials, and proof the remote mirror is current. |
 | [adding-swarm-patterns](skills/adding-swarm-patterns/SKILL.md) | 1.0.0 | Checklist for extending agent-relay with a new swarm pattern — TypeScript types, JSON schema, YAML template, and pattern/template docs. |
 | [creating-cloud-persona](skills/creating-cloud-persona/SKILL.md) | 1.0.6 | Create or update a Workforce cloud persona with `persona.json`/`persona.ts`, `agent.ts`, integration scope and adapter config guidance, vendored examples, and production-correctness checks. |
 | [factory-config](skills/factory-config/SKILL.md) | 1.0.2 | Create and validate Agent Relay Factory configs for repo routing, Linear states, GitHub issue ingestion, Slack, babysitter mode, and Relayflows dispatch wiring boundaries. |
