Cold intros spend other people's time without asking: the classic "meet X, you two should talk!" hands the busier party an obligation they never accepted. The double-opt-in flow fixes it — each side privately agrees before the connection happens — and the mechanical heart is the forwardable blurb: the requester writes three sentences the introducer can forward as-is, making the ask one tap to relay and one line to accept or quietly decline.
Double Opt In Intro is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/double-opt-in-intro/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked introduce me to someone, can you connect us, write an intro email, or someone asked me for an intro. Produces the opt-in asks for both sides, the forwardable blurb, the intro email itself, and the graceful decline path.
The Double Opt In Intro Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
