Add a locally-installable Claude Code plugin with 5 product discovery skills based on Teresa Torres (Continuous Discovery Habits), Marty Kagan (Inspired/Empowered/Transformed), and Google Ventures Design Sprint: - /ost — Opportunity Solution Tree builder (Torres) - /assumption-testing — Assumption mapping and experiment design (Torres + Kagan) - /discovery-coaching — Product discovery maturity coaching (Kagan + Torres) - /design-sprint — Google Ventures Design Sprint facilitator (Knapp) - /interview-planning — Customer interview planning and synthesis (Torres) https://claude.ai/code/session_012j6FJ9xZAzggZYkwxHYgrR
- Fix "Kagan" → "Cagan" across all skill files (10 occurrences) - Replace cryptic "/ost" skill name with "/opportunity-solution-tree" - Expand all "OST" abbreviations to "Opportunity Solution Tree" throughout cross-references in all skills https://claude.ai/code/session_012j6FJ9xZAzggZYkwxHYgrR
…, and routing Major changes across all 5 existing skills + 1 new skill: **All skills:** - Added hard rules / guardrails to prevent discovery theater - Added stronger trigger descriptions with concrete trigger phrases and negative triggers - Added anti-pattern detection at every step - Added kill criteria and decision outputs (proceed/iterate/pivot/kill) - Added solo founder / bootstrap adaptations throughout - Every skill now forces evidence before artifacts **opportunity-solution-tree:** - Evidence gate: refuses to populate opportunities without customer evidence - Requires 3+ solutions per opportunity (enforced, not suggested) - Decision output required at end of every tree - Evidence quality grading table **interview-planning:** - Added solo founder recruiting guidance (Reddit, Discord, LinkedIn, communities) - Added evidence strength grading (anecdote vs pattern vs strong signal) - Stronger synthesis section with frequency × intensity ranking - Explicit bans on feature-wishlist questions **assumption-testing:** - Kill criteria required for every experiment (non-negotiable) - Success criteria must be defined BEFORE running (enforced) - "Not yet killed" language instead of "validated" - Decision framework at end: if-pass/if-fail branching - Blocks testing easy assumptions before risky ones **discovery-coaching:** - Embedded full anti-pattern detector (12 patterns with symptoms/risk/corrective action) - Routing table to direct users to specific skills - Solo founder quick-start workflow - Context-dependent cadence design (solo vs trio vs org) **design-sprint:** - Scoped much tighter: explicit when-NOT-to-use section - Positioned as heavy intervention, not default tool - Hard rule: no sprint without access to real users for testing **NEW: discovery-intake (routing skill):** - Default entry point for product discovery - Decision tree that routes to the right skill based on context - Anti-pattern pre-check before routing - Minimum viable discovery cheat sheet for solo founders https://claude.ai/code/session_012j6FJ9xZAzggZYkwxHYgrR
