Pattern to PDF

Generate a shareable process briefing from a detected pattern or user-described workflow — a visual process map, step-by-step walkthrough, occurrence stats, and improvement opportunities. Output is a downloadable PDF.

The Goal

A PDD is a process briefing document — not a corporate BPM artifact with swim lanes and BPMN notation. It's the document you wish existed when you joined a team: "here's how we actually do X, step by step, with the apps involved, how long it takes, and what varies each time."

The pattern-detector finds that a process exists. The PDD describes how it works — with enough detail that someone unfamiliar could follow it, and enough structure to spot what's automatable.

Pattern Detector output:
  "Client Onboarding" — Email → CRM → billing → welcome email,
  3-4x/week, ~20 min each

              ↓ PDD Generator

Process Description Document:
  Executive summary — what, why, how often, how long
  At a Glance — stats bar with key metrics
  Process Map — visual flowchart showing each step
  Steps — numbered walkthrough with apps, actions, variations
  Opportunity — biggest time sink + concrete automation suggestion

Instructions

Step 1 — Identify the Process

Determine which process to document:

1. If the user names a specific pattern (e.g., from a previous /discover-patterns run), use that as the starting point.
2. If the user describes a process vaguely ("the thing I do with invoices"), ask a clarifying question to get the key apps and actions involved.
3. If nothing is specified, ask: "Which process would you like me to document? Name it or describe the key apps/steps and I'll find it in your activity."

Step 2 — Search for Instances

Cast a wide net across 30 days:

search_context(query="<process description + key apps>", startTime="30 days ago", endTime="now", limit=30)

Use the pattern name, key apps, and distinguishing actions as search terms. Try 2–3 query variations if the first returns sparse results (e.g., search by app name, then by action description, then by output artifact).

Step 3 — Cluster into Occurrences

Group returned activities by date proximity — activities within 60 minutes of each other likely belong to the same occurrence. Count distinct occurrences and note their date ranges.

• If 5+ occurrences: excellent — pick the 3–5 clearest for deep dive.
• If 3–4 occurrences: sufficient — deep dive all of them.
• If < 3 occurrences: use the fallback in Step 5.

Step 4 — Deep Dive

For the selected instances, fetch full details:

get_activity_details(ids=["id1", "id2", "id3", ...])

Use OCR text to understand exactly what happens at each step — what fields are filled, what data moves between apps, what decisions are made.

Privacy: never reproduce passwords, API keys, or personal messages from OCR in the output.

Step 5 — Fallback for Sparse Data

If fewer than 3 instances were found in Step 2:

1. Use any known dates from the search results as anchors.
2. browse_timeline around each known date with a ±2 hour window:

browse_timeline(startTime="<known_date> - 2 hours", endTime="<known_date> + 2 hours", limit=50, sampling="uniform")

3. Reconstruct the process sequence from surrounding context.
4. If still fewer than 2 clear instances after fallback, tell the user there isn't enough data to produce a reliable document. Suggest they try again after performing the process a few more times with MemoryLane running.

Step 6 — Synthesize

Cross-reference all deep-dived instances to build:

1. Canonical step sequence — steps that appear consistently across instances
2. Variations — what changes between instances
3. Decision points — where the process branches
4. Timing — average duration overall and per step (from timestamps)
5. Opportunity — biggest time sink and what's automatable

Step 7 — Render as PDF

Use the HTML Template below to produce the final document. Include:

1. Header with process name and scan metadata
2. Executive summary — 3–4 sentences
3. At a Glance stats — frequency, duration, apps, last seen, instances
4. Process map — vertical flowchart using the node types below (solid for constant steps, dashed for variable, distinct color for decisions)
5. Steps table — numbered walkthrough with app, action, and what varies
6. Opportunity section — time sink, automatable parts, concrete suggestion
7. Footer with methodology note

Convert to PDF:

1. Wrap the filled-in HTML template in a full HTML document:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8" />
    <style>
      @page {
        margin: 24px;
      }
      body {
        margin: 0;
        padding: 24px;
      }
      @media print {
        body {
          -webkit-print-color-adjust: exact;
          print-color-adjust: exact;
        }
      }
    </style>
  </head>
  <body>
    <!-- filled-in template HTML here -->
  </body>
</html>

2. Write to /tmp/pdd-temp.html using the Write tool.
3. Convert to PDF using Bash — use a slugified version of the process name (e.g., "Client Onboarding" → client-onboarding-pdd.pdf):

"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --headless --disable-gpu --no-pdf-header-footer --print-to-pdf="<slug>-pdd.pdf" /tmp/pdd-temp.html 2>/dev/null && rm /tmp/pdd-temp.html

If Chrome is not installed, fall back to saving as <slug>-pdd.html and tell the user.

4. Tell the user the PDF has been saved and they can open it.

Document Sections

1. Executive Summary

3–4 sentences covering:

• What the process accomplishes
• Why it exists (what business need it serves)
• How often it happens (frequency from occurrence data)
• How long it takes (average duration from timestamps)

2. At a Glance

A stats bar with key metrics at a glance:

Metric	Source
Frequency	Occurrence count ÷ time window (e.g., "~3x/week")
Avg duration	Mean time from first to last activity per occurrence
Apps involved	Distinct apps seen across all instances
Last seen	Date of most recent occurrence
Instances observed	How many occurrences the PDD is based on

3. Process Map

A vertical CSS flowchart — the visual centerpiece of the document.

Design rules:

• Vertical flow, top to bottom
• Each step = a styled node with an app badge (colored pill with app name) + action text
• Connector lines between steps (CSS borders/pseudo-elements)
• Decision points = distinct styled node (octagonal or highlighted border) with Yes/No branches
• Constant steps = solid border — these happen every time
• Variable steps = dashed border + annotation explaining what varies
• Steps derived from cross-instance analysis (Step 6)

Node anatomy:

┌─────────────────────────────┐
│  [App Badge]  Action text   │
│  "Enter client details"     │
└──────────────┬──────────────┘
               │
               ▼

Decision node anatomy:

        ┌──────────────┐
       ╱  International  ╲
      ╱    client?        ╲
      ╲                  ╱
       ╲                ╱
        └──┬────────┬──┘
       Yes │        │ No
           ▼        ▼

4. Steps

A numbered walkthrough — each step includes:

Field	Description
#	Step number in sequence
App	Which application is used
Action	What the user does (specific: "Enter client name and billing address", not "Use CRM")
What varies	What changes between instances (e.g., "Client name, billing amount") or "Nothing — identical each time"

5. Opportunity

A brief assessment:

• Biggest time sink — which step(s) consume the most time
• What's automatable — which constant steps could be scripted or API-driven
• One concrete suggestion — a single, actionable automation recommendation (same specificity level as pattern-detector suggestions)

Process Map HTML Design

The process map uses pure inline CSS (no classes, no external styles). It follows the same design language as the pattern-detector template.

Step node:

<div
  style="background: #fff; border: 2px solid #e2e8f0; border-radius: 10px; padding: 14px 18px; max-width: 420px; margin: 0 auto;"
>
  <span
    style="display: inline-block; background: #6366f1; color: white; font-size: 11px; font-weight: 600; padding: 2px 10px; border-radius: 99px; margin-right: 8px;"
    >{app_name}</span
  >
  <span style="font-size: 14px; color: #1e293b;">{action_text}</span>
</div>

Variable step node (dashed border):

<div
  style="background: #fffbeb; border: 2px dashed #f59e0b; border-radius: 10px; padding: 14px 18px; max-width: 420px; margin: 0 auto;"
>
  <span
    style="display: inline-block; background: #f59e0b; color: white; font-size: 11px; font-weight: 600; padding: 2px 10px; border-radius: 99px; margin-right: 8px;"
    >{app_name}</span
  >
  <span style="font-size: 14px; color: #1e293b;">{action_text}</span>
  <div style="font-size: 12px; color: #92400e; margin-top: 6px;">Varies: {what_varies}</div>
</div>

Decision node:

<div
  style="background: #f0f9ff; border: 2px solid #38bdf8; border-radius: 10px; padding: 14px 18px; max-width: 420px; margin: 0 auto; text-align: center;"
>
  <span style="font-size: 14px; font-weight: 600; color: #0369a1;">{decision_question}</span>
</div>

Connector between steps:

<div style="width: 2px; height: 28px; background: #cbd5e1; margin: 0 auto;"></div>

Branch connector (Yes/No):

<div style="display: flex; justify-content: center; gap: 80px; margin: 0 auto; max-width: 420px;">
  <div style="text-align: center;">
    <div style="font-size: 12px; font-weight: 600; color: #10b981; margin-bottom: 4px;">Yes</div>
    <div style="width: 2px; height: 20px; background: #10b981; margin: 0 auto;"></div>
  </div>
  <div style="text-align: center;">
    <div style="font-size: 12px; font-weight: 600; color: #94a3b8; margin-bottom: 4px;">No</div>
    <div style="width: 2px; height: 20px; background: #94a3b8; margin: 0 auto;"></div>
  </div>
</div>

HTML Template

Replace all {placeholders} with actual data. Step 7 handles wrapping this in a full HTML document and converting to PDF — this template is just the body content.

Calibration Examples

These show the expected level of detail. Each example: input pattern → what the PDD should contain.

Example 1: Client Onboarding

Input pattern: "Client Onboarding — Email → CRM → billing system → welcome email, 3-4x/week, ~20 min"

Expected PDD structure:

• Executive summary: "Client onboarding is a 5-step process that sets up new clients in the company's systems. It runs 3–4 times per week, triggered by a signed contract arriving via email. Average duration is 20 minutes. The process touches Gmail, HubSpot CRM, Stripe billing, and Gmail again for the welcome email."
• Process map: 5 nodes — (1) Gmail: Open signed contract email → (2) HubSpot: Create contact with company details [variable: client name, company, address] → (3) HubSpot: Add deal and set stage to "Won" → (4) Stripe: Create customer and subscription [variable: plan type, billing amount] → (5) Gmail: Send welcome email template [variable: recipient, personalized greeting]
• Decision branch: None observed — process is linear across all instances.
• Opportunity: Steps 2–4 are data entry of the same information into three systems. An intake form → API integration could eliminate 15 of the 20 minutes.

Example 2: Weekly Revenue Report

Input pattern: "Revenue reporting — Stripe → Google Sheets → formulas → Slack, every Monday, ~35 min"

Expected PDD structure:

• Executive summary: "The weekly revenue report aggregates Stripe payment data into a formatted summary shared with the finance team via Slack. It runs every Monday morning, takes approximately 35 minutes, and involves Stripe dashboard, Google Sheets, and Slack."
• Process map: 6 nodes — (1) Stripe: Export last 7 days of payments as CSV → (2) Sheets: Import CSV into "Weekly Revenue" tab [constant: same spreadsheet] → (3) Sheets: Update date range in summary formulas → (4) Sheets: Review computed totals, check for anomalies [variable: time spent varies 2–15 min depending on discrepancies] → (5) Sheets: Screenshot summary table → (6) Slack: Post screenshot + commentary to #finance [variable: commentary text]
• Decision branch: After step 4 — "Discrepancy found?" → Yes: investigate in Stripe (adds 10–20 min) → No: continue to step 5.
• Opportunity: Steps 1–3 are fully automatable via Stripe API → Sheets API. A scheduled script could have the spreadsheet pre-populated by Monday morning, reducing the process to review + post (~10 min).

Example 3: Expense Approval Batch

Input pattern: "Expense review — PDF open → policy check in browser → approve/reject in expense tool, 10-15 per batch, twice a week"

Expected PDD structure:

• Executive summary: "Expense approval processes 10–15 expense reports in a single sitting. It runs twice per week (typically Tuesday and Thursday), taking 30–45 minutes per batch. Each report involves reviewing the PDF, checking line items against company policy, and recording the decision."
• Process map: 4 nodes per report, wrapped in a "Repeat for each report" annotation — (1) Expense tool: Open next pending report → (2) Preview: Review PDF receipt/invoice [variable: vendor, amount, category] → (3) Browser: Check expense policy for category limits [variable: policy section checked] → (4) Expense tool: Approve or reject with notes [decision: "Within policy?" → Yes: approve → No: reject with reason]
• Decision branch: After step 3 — "Within policy limits?" → Yes: approve → No: reject with policy citation.
• Opportunity: Step 3 (policy lookup) is the bottleneck — different policy sections for different expense categories. A pre-check script that flags policy violations before human review would eliminate the manual lookup for ~80% of reports.

Notes

• Minimum data threshold — need at least 2 clear instances to produce a document. Below that, tell the user.
• Privacy — summaries are the primary data source. Only use get_activity_details for the deep-dive step. Never reproduce raw OCR in the output.
• Scope — one document per process. If the user wants multiple processes documented, run this skill once per process.
