parallel-skill-writes-in-single-tool-call-work-cleanly
Writing 4 or more SKILL.md files simultaneously via parallel Write tool calls in a single message response works without conflicts or race conditions. This is the correct pattern for batch skill creation (e.g., orchestrator + taste + multiple specialists in one round). Sequential writing of 21 skills in waves of 4 completed a full phase without errors. No locking or sequencing is needed for independent file paths under /root/.claude/skills/.
