# Ad Fatigue Check > 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). Find the ads whose audience has seen them too many times. Creative fatigue is a slow leak — the same creative keeps spending while frequency climbs, CTR erodes, and CPM drifts up as the algorithm works harder to place a tiring ad. This skill reads active ads per platform, measures the fatigue signals the tools genuinely expose, scores each ad against documented thresholds (with noise guards so a single slow day never triggers a rotation), and hands the fatigued ones to a creative refresh with the evidence attached. ## Prerequisites - STRATEGY.md and STATE.json must exist (run the `onboard` skill first) ## Steps **Before you start**: Run the **Diagnostic preamble** from ../_mureo-shared/SKILL.md — load learning insights (mureo_learning_insights_get) and consult advisors (mureo_consult_advisor) before drawing conclusions. 0. **Establish today**: call `mureo_state_get` **first, on every host** (including Claude Code, where you would otherwise `Read` the file) and take `server_now` from its response — ISO 8601 with UTC offset, e.g. `2026-07-28T10:12:33+09:00`. Its date is the **only source of the current date** for this run: the `observation_due` you write in step 9 is `server_now`'s date + 14 days. (The week-over-week windows in step 3 are platform-side period ...
