Phase 3 of the Legion AI Tools Factory pipeline. Authors the Cursor IDE subagent (Angel) file from a completed Command Brief and forged Weapon. Writes the YAML frontmatter, composes the body with proper Read-references to every file in the paired Weapon folder, wires the Angel to its guardrails and escalation paths, and declares a proactive/on-demand trigger policy. Use this skill whenever the user asks to "create the Angel", "author the subagent", "build the subagent file", "wire up the Angel", "finish the Angel", or signals that the Weapon is forged and it is time to assemble the subagent. Also trigger when weapon-forge has just announced its handoff or when the user points to a ready-to-use weapon folder and asks for its Angel.
