Convert books, course transcripts, article collections, podcast transcripts, workshop notes, reports, manuals, or other methodology-rich source materials into source-grounded installable Agent Skills. Use when the user wants to extract practical methods, frameworks, checklists, exercises, decision models, product playbooks, management systems, or repeatable thinking tools from long-form material and package them as reusable skills.
The user has product evidence and wants to decide whether to change direction. Use when the user wants to apply The Lean Startup's Pivot method to produce A pivot diagnosis report with evidence, failed assumption, recommended pivot, risks, and next validation experiment..
The user wants to test a product idea with the smallest useful experiment. Use when the user wants to apply The Lean Startup's Minimum Viable Product method to produce A concise MVP experiment plan with assumption, prototype scope, metric, threshold, timeline, risk, and next action..
The user wants to run an iterative product learning cycle. Use when the user wants to apply The Lean Startup's Build Measure Learn method to produce A Build Measure Learn cycle plan and learning record..

Translate the hypothesis into the smallest build action that can generate real user evidence.
Define actionable metrics, collection method, sample, and observation period.
Interpret the results against the pre-set decision rule. Summarize what has been validated or invalidated.
Suggest ways to reduce cost, time, and complexity in the next cycle.
