3Use this skill to first clarify the user's current situation, then turn it into a principal-contradiction diagnosis, a secondary-contradiction watchlist, a focused action plan, and a four-format report bundle.

7- ask concise follow-up questions before judging a user's current situation
8- assess whether the user's current situation is clear enough for diagnosis before naming the principal contradiction
9- produce a confirmable current-state snapshot with goal, facts, stage, resources, constraints, stakeholders, and repeated patterns
10- identify goals, stage, constraints, facts, stakeholders, resources, and repeated conflict patterns
11- rewrite messy symptoms as candidate contradictions in the form `力量A 与 力量B 的冲突`
12- run a first-principles layer scan so the principal contradiction can be an upstream, not-yet-visible constraint rather than the loudest symptom
13- use the three plain principal-contradiction checks: `决定性`, `牵引性`, and `阶段性`
14- separate internal changeable structures from external hard conditions, then judge how external conditions act through internal structure
15- use Bayesian-style evidence updates and Ockham-razor parsimony as supporting checks when candidate contradictions are close
16- score principal and secondary contradictions by goal impact, causal leverage, stage urgency, resource constraint, changeability, spillover risk, and evidence strength
17- identify the principal aspect inside the principal contradiction
