Setup (Run Once Per Session)
Before loading any sub-skill or resource, locate this skill's install directory:
- Use Glob to search for
**/list-building/SKILL.md - The directory containing this SKILL.md is
SKILL_BASE - Sub-skills are at:
{SKILL_BASE}/.claude/skills/{sub-skill}/SKILL.md - Resources are at:
{SKILL_BASE}/resources/...
Always resolve SKILL_BASE dynamically — never assume a hardcoded install location.

Full Workflow Template
For users asking for a complete list building workflow, read the beginner workflow template:
- File: Read
{SKILL_BASE}/resources/templates/beginner-workflow.md - Steps: Import Data -> Enrich Emails -> Merge Columns -> Validate -> Company Summary (GPT-4 mini) -> Check Fit (Claude) -> Push to Sequencer
- Key principle: Cheap AI for scraping, smart AI for interpretation, conditional formulas everywhere

Key Numbers to Remember
- 2,500 — Sales Navigator max results per search (bypass by segmenting)
- 22-30% — Annual email decay rate
- <1% — Target bounce rate for campaigns
- 95%+ — Target email deliverability
- 100 points — ICP scoring system (Tier A: 90-100, B: 70-89, C: 50-69, D: <50)
- 10-50 accounts — Tier 1 ABM (1:1 custom)
- 30 days — Re-verify lists older than this
Response Format
- Identify which sub-skill(s) the user needs
- If full workflow requested, present the beginner template first, then offer to deep-dive into any step
- Always clarify ICP if not provided (industry, company size, titles, geo, tech stack)
- Provide specific, actionable steps with tool recommendations
- Include relevant numbers (list size estimates, cost expectations, timeline)
