Fetched SKILL.md and all 5 reference files raw from wondelai/skills@main; frontmatter parses with name+description, and every referenced references/*.md file exists in the git tree and is substantive. Grep of skill + all references found no curl|sh, base64, exfil, secrets, or hidden instructions — only 3 disclosed Amazon affiliate tags (tag=wondelai00-20) on Further Reading book links. Trigger phrasings — ACTIVATE: "how do I get the first users for my two-sided marketplace?", "my social app has a chicken-and-egg problem, nobody's posting", "we're launching a marketplace with no buyers or sellers yet"; NOT: "write me a cold email sequence for B2B sales" (cold ≠ cold-start), "how do I improve my landing page conversion rate?" — 5/5 correct, description is well-scoped and cross-references sibling skills to avoid over-triggering.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 9/10
  • Docs & honesty 5/5

What Cold Start Problem does

A pure-prompt knowledge skill that turns Andrew Chen's "The Cold Start Problem" into a scored framework for launching and scaling networked products. Triggers on network-effects, marketplace-seeding, chicken-and-egg, and stalled-growth questions, then rates the plan 0-10 and prescribes atomic-network, hard-side, and liquidity-metric fixes.

How to install Cold Start Problem

Copy the cold-start-problem/ directory into .claude/skills/ (or .agents/skills/, etc. — the repo ships all five agent variants). Self-contained: SKILL.md plus 5 reference markdown files, no external CLI, MCP, or runtime required.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
