Clarify First

Before scoring leads, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• [ ] ICP definition — the must-have / nice-to-have / disqualifier attributes; this IS the scoring model
• [ ] Lead list columns — company, industry, size, country at minimum; missing fields mean no usable score
• [ ] GTM motion — PLG vs sales-led vs channel changes which signals weight highest and the outreach-hook framing

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Quick Start

Score a Lead List in 10 Minutes

• Define your ICP in icp.json using the schema in assets/icp_schema.json
• Save your lead list as a CSV with columns: company,industry,size,country,website,signals
• Run the qualifier:

   python scripts/lead_qualifier.py icp.json leads.csv

• Review the ranked output — top 20% is your A-tier outreach list

Core Workflows

Workflow 1: ICP-Based Lead Scoring

Goal: Rank a list of candidate accounts so the top of the list reflects the best fit, not the most recent import.

Steps:

• Build your ICP in icp.json — see assets/icp_schema.json for the full schema
• Capture leads in a CSV with at minimum: company,industry,size,country
• Run: python scripts/lead_qualifier.py icp.json leads.csv
• Sort the result by score (highest first); the top 20% is your A-tier
• Discard everything below the disqualification threshold rather than mass-emailing

Expected Output: Ranked list with score, tier (A/B/C/disqualified), and reason per lead.

Time Estimate: 10-15 minutes for a list of 200 leads.

Workflow 2: ICP Definition

Goal: Convert a fuzzy "we sell to ops teams at mid-market SaaS" intuition into a structured ICP that the qualifier can actually score against.

Steps:

• Pull the company names of your last 20-50 best customers
• Identify the shared signals: industry, size band, geography, tech stack, pain trigger
• For each, decide whether it's a must-have, nice-to-have, or disqualifier
• Encode in icp.json per references/icp_framework.md
• Pressure-test by scoring last quarter's closed-won and closed-lost accounts — the model should rank the wins above the losses

Expected Output: A versioned icp.json that retroactively predicts your past wins.

Time Estimate: 1-2 hours for first pass, 30 minutes per quarterly refresh.

Workflow 3: Outreach Hook Drafting

Goal: Write outreach where the personalization actually mentions a real signal, not a fake "I noticed you posted on LinkedIn."

Steps:

• Take the qualifier output for an A-tier lead
• Read the matched ICP signals — these are your hooks
• Use the outreach template in assets/outreach_template.md
• Personalize the opening line with the strongest signal (e.g., recent funding, hiring spike, product launch, public quote about a pain you solve)
• Keep the rest of the email short — sub-90 words

Expected Output: First-touch outreach email under 90 words with a real signal-based hook.

Time Estimate: 5 minutes per A-tier lead.

Tools

lead_qualifier.py

Reads an ICP JSON file and a leads CSV, returns a scored & tiered list.

# Human-readable
python scripts/lead_qualifier.py icp.json leads.csv

# JSON for programmatic use
python scripts/lead_qualifier.py icp.json leads.csv --json

Scoring model:

• Each ICP attribute has a weight (default 10) and direction (must / nice / disqualify)
• Must-have hits: full weight
• Nice-to-have hits: half weight
• Disqualifier hits: lead drops out of consideration entirely
• Score is normalized to 0-100

Reference Guides

• references/icp_framework.md — How to define an ICP that actually predicts deal velocity, with worked examples by GTM motion (PLG, sales-led, channel)

Templates

• assets/icp_schema.json — JSON schema for an ICP definition file
• assets/outreach_template.md — Cold-touch email template with placeholder slots tied to ICP signals

Best Practices

• Disqualify hard. Mediocre leads are worse than no leads — they consume rep time and damage sender reputation.
• Keep ICP versioned. When deal velocity drops, your ICP is often stale. Re-derive every quarter.
• One signal per email. Multi-signal openers feel like research dumps; one well-chosen signal feels human.
• Leads are not opportunities. A scored A-tier lead is permission to reach out, not a forecasted deal.
• Logs over feel. Track which signals correlate with closed-won — let data update the ICP, not vibes.

Integration Points

• Pairs with marketing/cold-email/ for sequence design
• Pairs with sales-success/ skills for account executive handoff
• Feeds into business-growth/ revenue forecasting
