Skill: tam-sam-som-builder

Purpose

Provide a realistic market size estimate that an indie developer can actually use for decisions. Most TAM estimates are useless because they use top-down analyst numbers designed to impress VCs, not to inform a solo builder deciding where to spend the next 6 months. This skill uses triangulated bottom-up methodology — multiple independent estimation approaches cross-checked against each other — anchored to real signals from market_insights/ trend data.

Input

• Idea slug (or market research slug for pre-idea deep dives)

• memory/ideas/<slug>/competitors.json (competitor scale and pricing signals)
• memory/ideas/<slug>/pricing.json (target price — if available)
• memory/market_insights/<niche>-*-<YYYY>-<MM>.md (trend analysis files — use all available platform files for this niche)
