ComposeAgent crashes: unquoted {PRINCIPAL.NAME} YAML key in Traits.yaml

[abseg]

Bug

ComposeAgent.ts crashes on every invocation with:

YAMLParseError: Map comment with trailing content at line 175, column 5
code: "IMPOSSIBLE"

Root Cause

In Releases/v4.0.3/.claude/skills/Agents/Data/Traits.yaml, line 175:

    {PRINCIPAL.NAME}:
      voice_id: "onwK4e9ZLuTAKqWW03F9"

{PRINCIPAL.NAME} is unquoted. YAML interprets {} as flow mapping syntax, so the parser sees an inline map followed by a trailing : — which is invalid.

Fix

Quote the key:

    "{PRINCIPAL.NAME}":
      voice_id: "onwK4e9ZLuTAKqWW03F9"

One-character fix. No other unquoted {PRINCIPAL.NAME} keys exist in the YAML files.

Reproduction

bun run ~/.claude/skills/Agents/Tools/ComposeAgent.ts --traits "technical,analytical,thorough" --task "any task"

Crashes 100% of the time on a clean v4.0.3 install.
