The repo root already IS the `ccam` plugin root (`"source": "./"`), so the conventional `skills/` dir at the root is the plugin's skills dir — while `.claude/skills/` only loaded for a session whose cwd was inside this checkout. That is useless for a lane working in another repo, which is why `ccam skills install` existed at all. Move all seven skills to `skills/`: they now reach every plugin user as `/ccam:<name>` (bare `/<name>` as an alias). `ccam skills install` stays as the fallback for a plain checkout without the plugin, sourcing from the new path. Agents deliberately do NOT move. A plugin agent is addressed as `ccam:qc-local`, which would break the `subagent_type: qc-local` references in ship-feature-lane; `ccam lanes agents install` keeps writing them into the lane's own `.claude/agents/`, the highest-priority agent source. MCP was already plugin-shipped via `plugins/ccam/.mcp.json`. Mechanical fallout: ~115 source files carry a doc-comment pointer to `.claude/skills/file-headers/`, repointed to `skills/file-headers/`. The generic Claude Code config-surface examples in openapi/cc-config (`.claude/ skills/code-reviewer`) describe any user's layout and are left alone. Also fixes the two file-headers scripts, whose `ROOT=` climbed four levels from `.claude/skills/file-headers/scripts/` and would have escaped the repo from the new depth — it scanned sibling projects until corrected to three. npm run test:server (1160 pass), test:client (422 pass), mcp:typecheck, mcp:build + mcp:check-build all green.
