Claude Skills by YuanpingSong

**Status:** Accepted 2026-07-06 · in progress (Phase A DONE 2026-07-06; B running).

Write Agent Script workflow files — deterministic multi-agent orchestration in one plain-JavaScript file, runnable unmodified by Claude Code's Workflow tool and by ultracodex. Use when asked to author, review, or fix a workflow script / Agent Script. Self-contained: no other document is required.

Design and stand up a generic filesystem-routed agent organization: a long-lived, self-scheduling, self-auditing org with per-entity memory, deterministic ingestion, audit, replay, and tick scheduling. Use when a domain needs continuous document or event intake, durable judgment that compounds by entity, and human-readable synthesis rather than one-shot workflow output.

Author and run multi-agent Agent Script workflows on the OpenAI Codex CLI (and OpenCode) via the ultracodex runner. Use when the user asks to run a workflow with ultracodex, orchestrate parallel agents, fan-outs, pipelines, or builder-verifier loops, to schedule recurring agent runs, to stand up an agent org, or to offload multi-agent execution from Claude to Codex.

Operate Embassy through current name@host or Claude session-UUID selectors and universal peer-* shell routes. Use when an agent needs to register for inbound messaging, await shell-peer mail, list available peers, refresh the operator's static dashboard, manage a user-chosen pair, send or reply under its own principal, or unregister without exposing provider credentials, socket paths, or message bodies.
