Why

wisdom-first is an Agent Skill that brings the right frameworks and books to bear before an AI improvises an answer. For a question that deserves real thought — strategy, high-stakes writing, a negotiation, a hard decision, a design — it surfaces two or three complementary frameworks and the best books, distills the moves that carry the weight, and then solves the problem through those lenses.

The design bet is that the reader keeps something durable: instead of outsourcing their judgment, they walk away with mental models and a reading list, so each answer also grows their own thinking. There is no "topic → book" lookup table — the right canonical works fall out of a pure, domain-blind selection taste, so it generalizes across domains it was never told about.

Notes

• Single feature per this PR (one skill, EN + zh-CN).
• Frontmatter follows src/content/skills/_template.md; the zh entry mirrors the existing skills-zh convention (slug + translated sections only).
• Agent-agnostic skill; also installable via the open skills CLI (npx skills add seacen/wisdom-first).
