# Learn > PREREQUISITE: Read `../_mureo-shared/SKILL.md` for auth, security rules, output format, and **Tool Selection** (Read/Write on Code, `mureo_strategy_*` / `mureo_state_*` MCP on Desktop / Cowork). Save a marketing diagnosis insight to the pro-diagnosis knowledge base. Saved insights are loaded at the start of future sessions and applied across `/daily-check`, `/rescue`, `/budget-rebalance`, and the other diagnostic workflows. The skill persists insights by shelling out to `mureo learn add`, which routes the write through the KnowledgeStore Protocol. The default backend writes to `~/.claude/skills/_mureo-pro-diagnosis/SKILL.md` (preserving the prior file layout); an alternate backend registered via the `mureo.runtime_context_factory` entry-point group can redirect or split the write without changing this skill. The knowledge base has two tiers — an **operator** tier shared across every workspace, and an optional **workspace** tier scoped to the current one. Use `mureo learn tiers` to find out which are available before deciding where an insight belongs (step 4). ## When to use - The user runs `/learn` followed by an insight, e.g.: - `/learn CV少ないサイトではマイクロCVを活用すべき` - `/learn 予算5000円/日で広告グループ8個は多すぎる` - `/learn Target CPA を下げすぎると逆に CV が減る` - The user runs `/learn` with no argument — review the current conversation for corrections or marketing expertise the user shared and propose those as insights. ## Steps 1. **Identify the insight.** If the user passed...
