description	Ptengine Heatmap end-to-end analysis skill. Fetches real heatmap data via ptengine-cli and runs AI-powered CRO behavior analysis using a 4-stage psychology model. Before analysis, runs a short brand & intent discovery step (optionally with lightweight website/brand research via http / browser) to ground conclusions in business context. Self-contained — includes all analysis methodology, data transformation rules, and output schemas. Use this skill when the user wants to: analyze a webpage's heatmap data, understand user behavior on a page, compare audience segments, validate A/B test results, evaluate ad channel performance, analyze audience characteristics, find conversion barriers or opportunities, or optimize a landing page. Trigger whenever: "analyze heatmap", "heatmap analysis", "page behavior", "analyze this URL/page", "how are users behaving", "compare segments", "A/B test results", "ad performance", "audience analysis", "ptengine", "block-level analysis", "conversion optimization", "exit rate", "dwell time", "user drop-off", "landing page analysis", or any request involving page analytics combined with behavioral insights.

Data Source Boundary

This skill has a two-track data source rule. Read carefully — the rule is different for heatmap data vs. brand context.

Data type	Authoritative source	Not allowed
Heatmap metrics and block structure (page_metrics, block_metrics, page_insight, block names, dwell, exit, impression, etc.) for the analyzed URL	ptengine-cli only	Using http / browser_* / screenshot / Playwright MCP to scrape the analyzed URL and fill / replace block content or metrics
Brand / company / product / audience / competitive context	http, browser_*, screenshot, or local file_read of a user-provided brand doc	—

Why the split matters (not just a preference): ptengine-cli returns aggregated behavior over the selected date range. The live page may have been edited — blocks added, removed, or reordered — since those users visited. Mixing a live scrape with historical aggregate data produces misleading analysis (e.g. attributing a low dwell time to copy that did not exist when the data was collected). Brand context is immune to this problem — a company's mission, product line, and target audience are not time-window-specific.

Concretely:

• Phase 0c.1 MAY fetch the site root, /about, /pricing, etc. via http / browser_* to inform brand_context (see references/discovery.md).
• Phase 1–6 MUST populate every metric and block-level field from ptengine-cli responses.
• If block content is missing from ptengine-cli's response, ASK the user — do not scrape the analyzed URL to fill it in.

Analysis Types

Type	Description	When to use
single_page	Deep single-page behavior analysis	Default. "How are users behaving on this page?"
compare	Cross-segment comparison	"Compare new vs returning visitors"
ab_test	A/B test hypothesis validation	"Which version won and why?"
ad_performance	Ad source quadrant analysis	"Which ad channels are performing?"
audience_analysis	Audience segment characteristics	"Who is visiting and how do they differ?"

Pipeline

Listed in execution order (not alphabetical). Letter labels are structural anchors for cross-references; the flow runs top-to-bottom:

Phase 0a: Prerequisites            # ptengine-cli install/config check
Phase 0c: Auto Research (optional) # runs before 0b when the first message lacks context
  0c.1: Website / brand research (web_fetch / http / browser, site root + about + pricing)
  0c.2: Lightweight block_metrics preview (ptengine-cli, only when it helps classification)
Phase 0b: Brand & Intent Discovery # informed clarifying questions, fewer after 0c.1 ran
Phase 0d: Parameter Collection     # URL, date range, analysis type, device, language, conversion
Phase 1: Data Fetch (ptengine-cli)
Phase 2: Page Classification
Phase 3: Data Enrichment (block content + phase assignment)
Phase 4: Input Assembly (transform to analysis format)
Phase 5: Analysis (apply methodology from references/)
Phase 6: Results Presentation

If the user already supplied enough context in the first message, Phase 0c and Phase 0b are skipped entirely. See references/discovery.md § Decision table for precise skip rules.

---

Phase 0a: Prerequisites

Check ptengine-cli

Run sh install.sh --check-only (or check command -v ptengine-cli):

• READY: Proceed to Phase 0b / 0c / 0d
• NEEDS_CONFIG: Ask the user for API Key and Profile ID. If the user does not have an API Key, walk them through the 6-step product-UI flow in references/ptengine-cli.md § "Obtaining an API Key". Then run: ptengine-cli config set --api-key <KEY> --profile-id <ID>
• NOT_INSTALLED: Run sh install.sh, then configure

---

Phase 0b: Brand & Intent Discovery

Read references/discovery.md before running this phase. In short:

• Do NOT jump to parameter collection if the user's first message lacks business context (brand / product / audience / primary goal). A generic dataset produces generic conclusions.
• Use think to pick at most 5 (usually 1–3) targeted questions from the bank in discovery.md § Question bank. Never re-ask anything the user already stated.
• Skip this phase entirely when (a) the user supplied ≥ 2 business signals upfront, or (b) the user says "just analyze" / "skip questions" / "直接分析".
• The phase produces a brand_context object (schema in discovery.md) that Phases 2 / 3 / 5 / 6 consume. The card never overrides metric evidence — it only shapes phrasing and finding priority.

---

Phase 0c: Auto Research (optional)

Two sub-probes, both optional.

0c.1 — Website / brand research

Run when the user gave a URL but little business context. Fetch at most 3 URLs (site root, /about, /pricing or similar) via http or, if JS-rendered, browser_navigate. Each page contributes ≤ ~1500 characters into think; total budget < 20 seconds.

Do NOT fetch the analyzed URL to replace ptengine-cli's block-level data. See references/discovery.md § Phase 0c.1 for the full boundary statement.

Record every fetched URL in brand_context.research_refs[]. On timeout or error, fall back to pure Phase 0b Q&A.

0c.2 — Heatmap preview (ptengine-cli)

Default posture: SKIP. Only run the 7-day block_metrics probe when page-type classification is still ambiguous after 0c.1 AND a block-names sample would materially disambiguate it. The probe informs preview_signals only; Phase 1 always performs the full-range fetch with the user's requested date range. See references/discovery.md § Phase 0c.2 for the full gate.

---

Phase 0d: Parameter Collection

Parameter	Required	Default	Notes
URL	Yes	—	Page URL to analyze
Date range	Yes	Last 30 days	YYYY-MM-DD
Analysis type	Yes	single_page	5 types above
Device type	For block data	MOBILE	PC or MOBILE (block_metrics cannot use ALL)
Language	No	ENGLISH	CHINESE / ENGLISH / JAPANESE
Conversion name	No	—	Fuzzy match for conversion metrics

For compare: which segments to compare (e.g. new vs returning visitors) For ab_test: campaign name, type (inline/popup/redirect), version info

If brand_context.primary_goal is known, prefer it as the conversion framing even when Conversion name is left blank.

---

Phase 1: Data Fetch

Read references/ptengine-cli.md for full command reference.

Core commands

# Page-level metrics
ptengine-cli heatmap query --query-type page_metrics \
  --url "<URL>" --start-date <START> --end-date <END> --output json

# Block-level metrics (MUST specify device type)
ptengine-cli heatmap query --query-type block_metrics \
  --url "<URL>" --start-date <START> --end-date <END> \
  --device-type <PC|MOBILE> --output json

# Dimension-grouped insights (for ad/audience analysis)
ptengine-cli heatmap query --query-type page_insight \
  --url "<URL>" --fun-name <sourceType|visitType|terminalType> \
  --start-date <START> --end-date <END> --output json

# Filtered data (for compare)
ptengine-cli heatmap query --query-type block_metrics \
  --url "<URL>" --start-date <START> --end-date <END> \
  --device-type MOBILE --filter "visitType include newVisitor" --output json

Error handling

• "success": false → show error message and hint
• Rate limited → check rateLimit.remainingMinute, wait if needed
• No data → suggest checking URL and date range

Data preprocessing (important)

ptengine-cli returns all metric values as formatted strings (e.g. "6,777", "55.08%", "3m 13s"), not raw numbers. Before proceeding to analysis, parse these strings into numeric values following the rules in references/data-transform.md § "Value format parsing". Getting this step wrong will produce incorrect analysis — pay special attention to percentage values (already percentages, do NOT multiply by 100 again) and duration formats (page-level uses "Xm Ys", block-level uses "Xs").

---

Phase 2: Page Classification

Read references/page-classification.md for full criteria.

If brand_context is populated, its business_model and (when present) preview_signals.proposed_page_type act as weak priors. Full-data signals (actual block names from Phase 1, full page_insight sourceType distribution) still override the prior when they disagree. Never skip the full classification check just because the prior looks confident.

Classify the URL into one of 7 types and map to internal key:

Result	Key	Notes
Sales Landing Page	sales_lp or ad_lp	ad_lp if ad traffic >50%
Article LP	article_lp
Product Detail Page	pdp
Homepage	homepage
Campaign / Promotion	sales_lp
Other Content	other_content
Other Function	other_function

If uncertain, ask the user.

---

Phase 3: Data Enrichment

Read references/block-analysis.md for the 4-phase psychology model and module categories.

3a. Block Content Analysis

For each block, determine module_category, content_summary, marketing_intent using the module categories for the detected page type. If brand_context.product_or_service or brand_voice is set, use it to choose between equally-grounded paraphrasings — do NOT invent block copy that ptengine-cli did not return.

3b. Block Stage Classification

Assign each block to phase 1-4 using the criteria in block-analysis.md. Load the correct phase names for the page_type and language from the phase name tables.

Use block_name and block position as primary signals when screenshots are not included in ptengine-cli's response. Do not fetch screenshots of the analyzed URL to substitute for ptengine-cli's block-level data (see Data Source Boundary — the first row of the table).

---

Phase 4: Input Assembly

Read references/data-transform.md for detailed field mapping, tag computation, and ranking algorithms.

Key steps:

1. Assemble base_metric from page_metrics response
2. Assemble block_data[] from block_metrics + Phase 3 enrichment
3. Compute tags (High/Medium/Low) and rankings if not provided by API
4. For ad/audience analysis: compute quadrant assignments

---

Phase 5: Execute Analysis

Based on analysis type, read the corresponding reference and follow its methodology:

Type	Reference file	Key output fields
single_page	references/single-page-task.md	core_insight, narrative_structure, barriers, opportunities
compare	references/compare-task.md	macro_performance, narrative_comparison, barriers/opportunities per segment
ab_test	references/ab-test-task.md	core_conclusion, hypothesis_validation with win_version_index
ad_performance	references/ad-performance.md	core_insights.summary, ad_performance_overview.description
audience_analysis	references/audience-analysis.md	core_insights.summary, user_profile.description

Before writing analysis, also read:

• references/page-types.md — interpretation guide for the detected page type
• references/quality-constraints.md — metric dictionary, evidence policy, terminology enforcement

If brand_context is populated, apply its framing per references/discovery.md § Handoff: primary_goal shapes which barriers/opportunities surface first; known_problems becomes a hypothesis the narrative can confirm or complicate (always hedged, always backed by metric evidence).

Critical quality gates (always apply)

1. Full block coverage: ALL blocks must appear in narrative structure (no omissions)
2. Directional consistency: Verify metric direction language matches the direction table
3. Evidence grounding: Always cite dwell + exit, use hedging for causal claims
4. No technical leaks: No block_ids, camelCase keys, or raw tags in output text
5. Language purity: No mixed-language output; apply terminology enforcement
6. Source separation: fvDropOffRate from base_metric only; exitRate from block_data only
7. Low sample warning: If total visits < 100 or a block's impressionRate is very low (< 10%), note the limited data confidence in the analysis. Metrics from very few sessions can be misleading.

Phase 6: Present Results

Output a human-readable Markdown report in the target language — not JSON. The report is for marketing practitioners, CRO specialists, and site operators who need actionable insights.

Each analysis type has its own report template defined in the corresponding reference file. The general structure is:

1. Core finding — the single most important insight, prominently displayed
2. Detailed analysis — phase-by-phase narrative (behavior tasks) or structured comparison
3. Barriers and opportunities — clearly separated with supporting data
4. Improvement suggestions — 1-3 concrete, actionable recommendations
5. Next steps — offer to run a different analysis type, compare segments, or save results

When brand_context.source != "none", open the report with a one-sentence framing line that ties the analysis to brand_context.primary_goal. If brand_context.research_refs is non-empty, a small "Sources consulted" footnote listing those URLs may be appended at the end of the report. Do NOT echo brand_context itself as raw YAML in the report.
