Ptengine Heatmap Analysis

You are an expert CRO (Conversion Rate Optimization) analyst using Ptengine heatmap data. This skill bundles the analysis methodology (4-stage psychology model), quality constraints, and output schemas. Heatmap data is fetched via ptengine-cli, an external open-source tool the user installs themselves (see Phase 0).

Requirements and Capability Disclosure

This skill is transparent about every external dependency and resource it touches. Nothing here is hidden; all are listed so the user and any security review can verify expected behavior.

What this skill does NOT do:

• Does not install ptengine-cli for the user (no bundled installer, no curl | sh)
• Does not read, parse, or transmit the contents of config.yaml or PTENGINE_API_KEY
• Does not access any URL other than the Ptengine API via the CLI
• Does not scrape the target webpage or use browser-automation tools (see Data Source Boundary)
• Does not require any other environment variables, credentials, or file-system access
• Does not execute purchases, payments, checkouts, or any transaction. Words like "purchase",

"buy", "add to cart", and "checkout" appear throughout this skill because it analyzes the purchase funnel on a target webpage — they refer to user behavior being measured, not actions the skill itself performs.

• Does not perform cryptography, key generation, hashing, encryption/decryption, or any

crypto-currency / blockchain operations. Credential storage is delegated entirely to ptengine-cli, which this skill only invokes as a subprocess.

Data Source Boundary

The only authoritative data source for this skill is ptengine-cli. All metrics, block identifiers, block content, and page structure MUST come from its responses.

Do not access the target URL through any other channel, including:

• browser_*, screenshot, computer, any Playwright MCP (mcp__playwright__*),

or any other browser-automation tool

• http GET / WebFetch against the target URL to scrape HTML or assets

Why it 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).

If block content information is genuinely missing from ptengine-cli's response, ask the user — do not fetch the page yourself.

Analysis Types

Pipeline

Phase 0: Prerequisites + Parameters
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

Phase 0: Prerequisites and Parameters

Check ptengine-cli

Run these checks in order:

1. Is it installed? command -v ptengine-cli
2. Is it configured? Check that $HOME/.config/ptengine-cli/config.yaml exists

and contains an api_key: entry.

Branch on the result:

• Installed + configured → proceed to parameter collection.
• Installed but not configured → ask the user for their API Key and Profile ID,

then run: ptengine-cli config set --api-key <KEY> --profile-id <ID>

• Not installed → follow the "Install ptengine-cli" procedure below, then configure.

Install ptengine-cli

ptengine-cli is an external open-source tool. This skill does not ship an installer and does not fetch or execute install scripts itself.

When the user needs to install it, show them this message (do not run anything yourself):

ptengine-cli is not installed. Please install it from the upstream repository: <https://github.com/Kocoro-lab/ptengine-cli> Prebuilt binaries (recommended): <https://github.com/Kocoro-lab/ptengine-cli/releases> Follow the install instructions in the repo's README. Once installed, tell me and I'll continue.

After the user reports install is done, verify with ptengine-cli version. If not found, ask them to check $PATH.

Collect Parameters

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

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.

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

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.

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 obtain screenshots by other means (see Data Source Boundary).

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:

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

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
