Build a personal Skill

Derive reusable instructions from the user's evidence. Do not decide their preferences in advance.

Workflow

Call search_classrooms and search_chats with an empty query to inventory the history. Page further when hasMore is true and more candidates could change the sample.
Choose a representative spread of classrooms and chats by topic, format, time, and outcome—not merely the newest records.
Use read_classroom and read_chat to inspect the selected evidence. Read relevant sections and continue their pagination until the needed sample is complete.
State provisional patterns as hypotheses. Run narrower searches to find confirming and disconfirming examples; read those results before concluding.
Call ask_user to show the evidence-backed hypotheses and ask the user to correct, prioritize, or reject them. Ask at least once unless the user explicitly says not to ask follow-up questions. The answer continues this authorized Skill-creation workflow.
If the answer exposes a gap, search or read again. If evidence remains insufficient, say what is missing and ask the user; never fabricate a preference.
Write self-contained instructions that explain when the Skill applies, the user's preferred workflow, constraints, quality bar, and exceptions. Then call create_skill with the final content. Do not merely print or preview the Skill in assistant prose.
An authorized creation turn may end only after a successful create_skill call, or after a successful ask_user call for a genuine unresolved decision. If the user has answered and no decision remains, call create_skill before ending.
