Performance Check Skill for Claude

/digital-marketing-pro:performance-check

Purpose

Pull live metrics from all connected analytics MCPs and produce a comprehensive performance snapshot. Compares current performance to KPI targets defined in the brand profile, previous-period benchmarks, and industry averages. Designed for quick health checks — run it daily, weekly, or on-demand to stay on top of marketing performance without switching between platforms.

Scope (vs /digital-marketing-pro:performance-report): this skill is the live-pull + snapshot-persistence layer — it fetches current metrics from the platforms and saves a snapshot for trend history. When you need a formatted, narrative deliverable for stakeholders (executive summary, channel commentary, prioritized recommendations, branded formatting), run /digital-marketing-pro:performance-report, which consumes the snapshots this skill persists rather than re-pulling. Use performance-check to *see the numbers now*; use performance-report to *tell the story*.

Input Required

The user must provide (or will be prompted for):

• Time period: Today, this week, this month, this quarter, or a custom date range (e.g., "last 14 days", "Jan 1 - Jan 31")
• Channel focus (optional): Specific channels or platforms to prioritize (e.g., "paid search only", "email and social").

If omitted, all connected platforms are included

• Comparison period (optional): Period to compare against — previous period, same period last year, or custom range.

Defaults to the equivalent previous period

• KPI targets (optional): Override targets for this check.

If omitted, targets are pulled from profile.json goals and KPI settings

• Granularity (optional): Daily, weekly, or aggregate view. Defaults to aggregate for the selected period

Process

• Load brand context: Read ~/.claude-marketing/brands/_active-brand.json for the active slug, then load ~/.claude-marketing/brands/{slug}/profile.json. Apply brand voice, compliance rules for target markets (skills/context-engine/compliance-rules.md), and industry context. Also check for guidelines at ~/.claude-marketing/brands/{slug}/guidelines/_manifest.json — if present, load restrictions. Check for agency SOPs at ~/.claude-marketing/sops/. If no brand exists, ask: "Set up a brand first (/digital-marketing-pro:brand-setup)?" — or proceed with defaults.
• Detect connected analytics MCPs: Check .mcp.json and active MCP connections to identify which platforms are available

(google-analytics, google-ads, meta-marketing, linkedin-marketing, tiktok-ads, mailchimp, stripe, mixpanel, amplitude, shopify, etc.).

Log any expected platforms that are not connected so the user knows about gaps in coverage.

• Pull metrics from each connected platform: Request key metrics for the specified time period:
• Traffic: sessions, users, pageviews, new vs returning (break out GA4's "AI Assistant" default channel — referrals from ChatGPT, Gemini, Copilot, Perplexity, etc. — so AI-sourced traffic isn't buried under Referral/Direct)
• Ads: impressions, clicks, spend, CPC, CPM
• Conversions: leads, purchases, sign-ups, goal completions
• Revenue: total revenue, average order value, transaction count
• Engagement: open rate, click rate, bounce rate, time on site
• Platform-specific: email deliverability, social reach, video views, app installs
• Aggregate into unified dashboard: Normalize metrics across platforms into a single cross-channel view with consistent

naming, currency conversion if multi-currency, and de-duplicated conversion counts where platforms overlap

• Calculate KPIs vs targets: Compare actuals to targets from profile.json goals — flag green (on track or exceeding),

yellow (within 10% of target), or red (missing by >10%). Include absolute and percentage variance for each KPI.

• Compare to previous period: Calculate period-over-period change for every metric and attach trend direction

(up/down/flat) with percentage change. If year-over-year data is available, include as a secondary reference point.

• Benchmark against industry: Reference skills/context-engine/industry-profiles.md for the brand's industry to

contextualize performance relative to category averages. Flag metrics significantly above or below industry norms.

• Identify notable findings: Surface the top 3 wins (best-performing metrics or biggest improvements), top 3 concerns

(underperforming or declining metrics), and any material changes that warrant deeper investigation. Before labelling a

conversion-rate change "statistically significant," confirm it with python "${CLAUDE_PLUGIN_ROOT}/scripts/significance-tester.py" --control-visitors {n} --control-conversions {n} --variant-visitors {n} --variant-conversions {n} --confidence 0.95 — do not call a movement significant off a raw percentage delta.

• Generate recommended actions: Based on the data, produce 3-5 specific, actionable next steps — e.g., "Pause

underperforming ad set X", "Increase budget on high-ROAS channel Y", "Investigate traffic drop on Z",

"Scale winning creative variant", "Run /digital-marketing-pro:anomaly-scan for deeper diagnosis".

10. Save performance snapshot: Execute python "${CLAUDE_PLUGIN_ROOT}/scripts/performance-monitor.py" --brand {slug} --action save-snapshot --data '{...current metrics...}'

to persist the snapshot for historical comparison and trend tracking across future runs.

11. Log significant insights: For any metric with a notable deviation, save via

python "${CLAUDE_PLUGIN_ROOT}/scripts/campaign-tracker.py" --brand {slug} --action save-insight --data '{"type":"anomaly","insight":"...","context":"..."}'

so findings surface in future reports and campaign planning.

Output

A structured performance snapshot containing:

• Executive summary: 2-3 sentence overview of overall marketing health with the single most important finding highlighted
• Channel-by-channel metrics table: Traffic, impressions, clicks, conversions, revenue, spend, CPA, ROAS, and engagement

rate per platform — sortable by any column

• KPI scoreboard: Each tracked KPI with actual value, target value, percentage to target, variance (absolute and %),

trend arrow (vs previous period), and RAG status (red/amber/green)

• Cross-channel summary: Total spend, total conversions, blended CPA, blended ROAS, total revenue, marketing efficiency

ratio, and overall health assessment

• Period-over-period comparison: Percentage change for all key metrics vs the comparison period with directional

indicators and sparkline-style trend data

• Industry benchmark context: How key metrics compare to industry averages from industry-profiles.md, with percentile

ranking where data is available

• Notable findings: Top 3 wins, top 3 concerns, and any anomalies worth investigating further — each with supporting

data points and severity indicator

• Recommended actions: 3-5 specific next steps with priority ranking, expected impact, and the platform or campaign

each action applies to

• Data gaps: Any platforms that were expected but not connected, metrics that could not be retrieved, or time periods

with incomplete data — so the user knows what is missing from the picture
