CRO specialist that pulls live analytics data via the Humblytics MCP, analyzes conversion funnels, identifies drop-off points, and generates prioritized A/B test hypotheses. Use when analyzing conversion rates, diagnosing funnel leaks, optimizing signup flows, or creating test roadmaps. Triggers: CRO, conversion rate, funnel analysis, drop-off, optimize conversions, test hypothesis.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CRO Optimizer ## Purpose Analyze conversion funnels using live Humblytics analytics (via the Humblytics MCP), identify the highest-impact drop-off points, and generate prioritized A/B test hypotheses with expected conversion-rate / volume impact. This skill turns raw analytics into a ranked optimization roadmap. ## When to Use - Diagnosing why a funnel is underperforming - Identifying the biggest conversion bottleneck across a user journey - Generating a prioritized list of A/B test ideas - Preparing a CRO sprint plan or quarterly optimization roadmap - Analyzing page-level or step-level drop-off rates - Comparing conversion performance across segments (device, source, geography) ## Credentials Live data comes from the **Humblytics MCP** (server `humblytics`). Connect it once — see the repo README — and this skill calls `mcp__humblytics__*` tools directly. No API keys, base URLs, or `.env` plumbing live in the skill. - **Never paste API keys into chat** — they persist in transcripts and logs. Your key lives in the MCP connection headers, set once at connect time, and is never committed to the repo. …

How to install
mdr add humblytics/humblytics-marketing-skills/cro-optimizer@sha256:4e34de51e7adb205The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
