Ephemera paths: resolve FEATURE_CODE / <CODE> then follow templates/skills-ephemera-paths.md (feature root .skills/<CODE>/). Resolve pack seeds in this order, first path that exists: (1) templates/ beside this SKILL.md, (2) ${CLAUDE_PLUGIN_ROOT}/templates when that variable is set, (3) ../../../templates relative to this SKILL.md.

Build Inline

Drive an approved plan to completion yourself, task by task, with no implementer (or reviewer) subagent dispatches. Every step is test-first. Progress survives in the ledger. Finish with whole-branch review.

This is not subagent orchestration. Continuous multi-task subagent waves are build-in-waves. Human-gated review units with subagents are build-by-story.
