Lossless CRM Interface Guidelines is a community-contributed Claude Code skill in the crm-systems sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/lossless-crm-interface-guidelines/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use whenever adding or enriching a company, person, deal, thesis, event, or portfolio relationship; when triaging a list or export into the CRM; or when extending the CRM schema. Encodes instance routing, the custom object model (Investment, Deal Source, Deal Prospect, Thesis, Thesis Fit, Events), the forced-choice scoring standard, provenance rules, and known MCP pitfalls.
