Performance monitor skill

Performance Monitor

One monitor skill, two modes. report builds a stakeholder-facing multi-metric snapshot of what already happened (traffic, rankings, GEO/AI, authority, backlinks, content) and turns period-over-period deltas into prioritized recommendations. alert configures forward-looking threshold and anomaly notifications so a drop in rankings, traffic, technical health, backlinks, competitor position, or AI citations fires before someone eyeballs it. Pick the mode from intent: past-tense reporting → report; future-tense "tell me when" → alert.

Mode set: report (multi-metric snapshot) · alert (forward thresholds/anomalies). Default when unstated: infer from verb tense (see Decision Gates).

Scope guard — what this skill does NOT do: it does not compute the CORE-EEAT content score or run its vetoes (T04/C01/R10) — that gate is content-quality-auditor; it does not compute the CITE domain score or run its vetoes (T03/T05/T09) — that gate is domain-authority-auditor. This skill reports those scores when a gate has already produced them and watches them for change; it never scores. Raw position-by-position ranking deltas belong to rank-tracker.

Quick Start

# report mode
Create an SEO performance report for [domain] for [time period]
Generate an executive summary of SEO performance for [month/quarter]
Create a GEO visibility report for [domain]

# alert mode
Set up SEO monitoring alerts for [domain]
Create ranking drop alerts for my top 20 keywords
Alert me when AI citations for [domain] drop

Shortest valid invocation: performance-monitor <domain> (mode inferred). Output: report returns a metric-table → what-changed → why → next-action dashboard with every figure source-tagged; alert returns an alert-config summary with named triggers, thresholds, priorities, and delivery routing. Both emit a handoff summary ready for memory/monitoring/.

Skill Contract

Expected output: mode report → a delta-based multi-metric report/dashboard plus per-change Cycle Retro; mode alert → an alert configuration summary that opens a bound readback rather than declaring an instant outcome. Both include exact page/change/measurement bindings, evidence refs, and the standard handoff summary for memory/monitoring/.

• Reads: prior baselines and current performance data. report reads current + prior-period metrics across traffic/rankings/authority/content, report audience, and date range. alert reads baselines, critical keywords/metrics to watch, normal volatility, and delivery preferences. Plus any user-provided or tool data.
• Writes: a user-facing monitoring deliverable plus a reusable summary storable under memory/monitoring/.
• Promotes: significant changes, confirmed anomalies, durable thresholds, and follow-up actions; pending decisions go to memory/open-loops.md (never directly to decisions.md).
• Done when:
  • report: each in-scope section (traffic, rankings, GEO, authority, backlinks, content) is present or marked "Not yet evaluated"; every metric is source-, time-, window-, and target-bound and compared to the prior period/control; each changed page records the current page/content/change and measurement-contract refs/hashes; recommendations carry owner, priority, and expected impact.
  • alert: each chosen alert category has a named trigger, threshold, and priority; a Critical/High/Medium/Low response plan and delivery routing are defined; thresholds are tuned to the metric's stated normal volatility.
• Primary next skill: see Next Best Skill — the two modes hand off to each other.

Handoff Summary

Emit the standard shape from skill-contract.md §Handoff Summary Format. Name the active mode (report / alert) in the Objective line.

Data Sources

All integrations optional (see CONNECTORS.md). Tier 1 (keyless) works for both modes; keyed tools are opt-in Tier 2/3.

• report: with tools connected, aggregates traffic from ~~analytics, search data from ~~search console, rankings/backlinks from ~~SEO tool, and AI visibility from ~~AI monitor. Without tools, ask the user for analytics exports, Search Console data, ranking data, and KPIs.
• alert: with tools, monitor real-time feeds from ~~SEO tool, ~~search console, and ~~web crawler. Without tools, ask for baselines, critical keywords, delivery preferences, and historical data.

Zero-dependency measurement loop (both modes): every reported change or fired alert should come from a computed delta, not an eyeballed estimate. Store each period's KPIs and let the ledger compute movement: python3 "${CLAUDE_PLUGIN_ROOT}/scripts/connectors/ledger.py" record <domain> --source monitor --data '{"sessions": ..., "clicks": ..., ...}', then ledger.py diff <domain> --source monitor for the period delta and ledger.py trend <domain> --source monitor --field <kpi> for the trend line. Label every figure Measured / User-provided / Estimated, and attribute outcome movement against a control rather than to the latest change — see references/measurement-protocol.md. See scripts/connectors/README.md.

Decision Gates

Stop and ask the user when:

• Mode ambiguous — the request fits neither past-tense ("report on last month") nor future-tense ("tell me when X drops"). Offer: (1) report a snapshot now, (2) alert for ongoing monitoring, (3) both.
• report: no reporting period or comparison period can be determined and none is in context — offer (1) last 30 days vs prior 30, (2) last calendar month vs prior month, (3) a custom range. A period comparison is required, not optional.
• alert: no baseline or normal-volatility reference exists for the metrics to watch — thresholds would be arbitrary. Offer (1) supply recent baseline data, (2) use the Alert Threshold Quick Reference defaults and label them Estimated, (3) cancel.

Continue silently (never stop for):

• A report section's source data is missing — mark that section "Not yet evaluated" and proceed; do not fabricate the metric.
• Audience not stated (report) — default to the executive template and note the assumption.
• Delivery channel not stated (alert) — default to the channel in context (or email) and note it.
• An alert category the user did not mention — leave it unconfigured; do not add alerts they did not request.

Instructions

Step 0 — Select mode. Read --mode if given. Otherwise infer: past-tense / "how did we do" / "月报" → report; future-tense / "tell me when" / "预警" → alert. If neither fits, use the mode-ambiguous gate above.

Mode: report

Use Report Output Templates and cover:

1. Define Report Parameters — domain, period, comparison period, report type, audience, focus areas, data freshness.
2. Executive Summary — overall rating, wins, watch areas, required actions, metrics-at-a-glance (traffic, rankings, conversions, DA/authority, AI citations), and SEO ROI; tag each metric Measured / User-provided / Estimated.
3. Organic Traffic — sessions, users, pageviews, engagement/bounce, trend, source/device split, top pages, each figure source-tagged.
4. Keyword Rankings — position ranges, distribution change, top improvements/declines, SERP features. For raw position-by-position deltas, defer to rank-tracker rather than recomputing here.
5. GEO / AI Performance — AI citation overview, citations by topic, GEO wins, optimization opportunities.
6. Domain Authority (CITE) — include CITE dimension scores and veto status when a gate has already produced them; otherwise mark "Not yet evaluated." Do not compute CITE here.
7. Content Quality (CORE-EEAT) — include average scores and trends when already produced; otherwise mark "Not yet evaluated." Do not compute CORE-EEAT here.
8. Backlinks — link-profile summary, acquisition trend, notable links, competitive position.
9. Content Performance — publishing summary, top content, content needing attention, content ROI.
10. Recommendations — immediate/short-term/long-term actions with priority, owner, expected impact, next-period goals.
11. Compile Full Report — table of contents, appendix, data sources, methodology, glossary.

Mode: alert

Use Alert Configuration Templates and:

1. Define Alert Categories — choose from rankings, traffic, technical, backlinks, competitors, GEO / AI, and brand.
2. Configure Alert Rules by Category — define trigger condition, threshold, alert name, and priority for each relevant rule; tie each threshold to a stated baseline and label that baseline Measured / User-provided / Estimated.
3. Define Alert Response Plans — map Critical / High / Medium / Low to response time and next actions.
4. Set Up Alert Delivery — channels, routing, cooldowns, maintenance windows, escalation paths.
5. Create Alert Summary — output category counts, the critical playbook, and a weekly review checklist as the deliverable.

Shared discipline (both modes)

Label every metric Measured (tool/export), User-provided, or Estimated (model inference); never present an estimate as measured; if a required metric is unavailable, mark it N/A — do not invent it. Separate an observed change from a plausible explanation (corroborate before stating a cause), an optimization opportunity, and follow-up needing crawl/SERP/rank/audit — never report an unverified explanation as a confirmed cause.

Alert Threshold Quick Reference

Metric	Warning	Critical	Frequency
Organic traffic	-15% WoW	-30% WoW	Daily
Keyword positions	>3 position drop	>5 position drop	Daily
Pages indexed	-5% change	-20% change	Weekly
Crawl errors	>10 new/day	>50 new/day	Daily
Core Web Vitals	"Needs Improvement"	"Poor"	Weekly
Backlinks lost	>5% in 1 week	>15% in 1 week	Weekly
AI citation loss	Any key query	>20% queries	Weekly
Security issues	Any detected	Any detected	Daily

Steep-decline trigger (always on): if organic traffic OR aggregate keyword rank falls >30% below its trailing baseline (default: prior 28-day median for the same weekday band), fire a Critical alert regardless of category. Use a trailing median, not a single prior day, so one noisy data point does not trip it. Label the baseline Measured / User-provided / Estimated.

Reading Deltas Against a Control

A reported delta or a fired alert is only evidence if it beats a control over a fixed readback window set before the change — a raw before/after on a confounded outcome is a story, not proof. Attach the decision protocol from references/measurement-protocol.md §Cross-discipline decision protocol:

First apply the SEO/GEO Evidence and Cycle Control Profile. The readback must bind the current non-forked page/content/change head and exact measurement-contract hash. A later edit supersedes the old binding and starts a new window; a post-hoc window is explicitly reconstructed.

• Readback window — pick the window for the change type up front (content refresh 7/14/28/56 days; new content 14/28/56/90; technical fix daily ×7 then 28; AEO/GEO surfacing weekly) and do not react to noise inside it. A fired alert opens a readback window, not an instant verdict — confirm the drop holds before declaring an incident.
• Required readback fields — record: page/content/change refs + hashes · current head · measurement contract ref/hash · owner · baseline/candidate/control windows · evidence refs · primary + secondary metric · decision · caveats · next patch · next-readback date · applicable index receipt.
• Decision — mark each change Promote (beats control on the primary metric past the bar), Keep-testing (trending, not yet significant), Rollback (loses by the same bar), or Unproven (everything else). Report delta-vs-control, not raw delta.

Example

• report: an executive summary with overall status, metrics-at-a-glance for traffic/rankings/conversions/authority/AI citations, SEO ROI, and immediate/month/quarter actions with owners and dates.
• alert: a keyword alert matrix with Critical vs High thresholds, a response plan for drops, and notification routing to email + Slack.

Save Results

Ask "Save these results?" If yes, write to memory/monitoring/ using filename YYYY-MM-DD-<topic>.md — see skill-contract.md §Save Results Template. This is a non-auditor skill: ask before writing memory and hand off veto-like risks to the relevant auditor gate rather than appending veto markers itself.

Next Best Skill

Mode-conditional, then terminal:

• After report — a change needs ongoing monitoring → run this skill in alert mode. A section marked "Not yet evaluated" for authority → domain-authority-auditor; for content quality → content-quality-auditor. One-off report with no action → Terminal.
• After alert — a reporting cadence is requested → run this skill in report mode. Standalone alert setup → Terminal.

Termination: the visited-set and max-depth: 3 rules from skill-contract.md §Termination rules apply. Do not re-enter a mode already run in this chain (report→alert→report is a visited-set stop); if routing is ambiguous, present the options and stop instead of auto-following.
