Thinking Bounded Rationalitytjboudreaux/cc-thinking-skillsUse when search or investigation could run forever. Set an explicit good-enough threshold first, then stop at the first option that clears it.01 Thinking Circle Of Competencetjboudreaux/cc-thinking-skillsUse when a specific claim may lack grounding. Check evidence boundary, size wrongness cost, then answer, fetch, or abstain — never confabulate.01 Thinking Cynefintjboudreaux/cc-thinking-skillsWhen the right response mode is unclear, classify the cause-effect domain first; decompose disorder.01 Thinking Effectuationtjboudreaux/cc-thinking-skillsUnder genuine uncertainty with no reliable forecast, inventory means, cap downside at affordable loss, act for commitments, and let goals emerge from controllable moves.01 Thinking First Principlestjboudreaux/cc-thinking-skillsWhen a constraint is treated as fixed, separate physics from convention, keep only independently supported primitives, and rebuild the simplest solution that satisfies real constraints.01 Thinking Five Whys Plustjboudreaux/cc-thinking-skillsWhen a fault is localized and the proximate cause is known but the systemic root is not, chain evidence-linked whys with a counterfactual stop and a countermeasure.01 Thinking Jobs To Be Donetjboudreaux/cc-thinking-skillsDeciding what to build or why adoption fails. Recover the progress users hire a solution for under a circumstance, then rank by outcome and competing workarounds.01 Thinking Kepner Tregoetjboudreaux/cc-thinking-skillsUse when a selective defect needs IS/IS-NOT difference analysis or a consequential option choice needs must/want weighting and adverse-consequence comparison.01 Thinking Lindy Effecttjboudreaux/cc-thinking-skillsUse when longevity of a non-perishable option matters. Treat survival duration as a remaining-life prior, then check domain drift before favoring the proven.01 Thinking Map Territorytjboudreaux/cc-thinking-skillsWhen a claim, doc, test, metric, or assumption conflicts with observed behavior, stop theorizing from the map and verify the live code or data; let territory overrule.01 Thinking Margin Of Safetytjboudreaux/cc-thinking-skillsWhen provisioning, setting a limit, or committing an estimate under uncertainty, size a buffer to residual error and the cost of breach—not to the optimistic edge.01 Thinking Model Combinationtjboudreaux/cc-thinking-skillsWhen one mental model leaves a material blind spot on a multi-domain or high-stakes problem, sequence complementary models with named roles and a conflict rule.01 Thinking Model Routertjboudreaux/cc-thinking-skillsWhen unsure which thinking skill fits, map domain and problem type, then return NONE or one primary skill by default (at most three complementary).01 Thinking Oodatjboudreaux/cc-thinking-skillsUse under time pressure when the situation is still changing and you must act before certainty — cycle Observe→Orient→Decide→Act on ~70% confidence, then re-observe.01 Thinking Opportunity Costtjboudreaux/cc-thinking-skillsBefore committing scarce time, people, or money, name the best forgone use of those resources and the value delta of the chosen path versus that alternative.01 Thinking Pre Mortemtjboudreaux/cc-thinking-skillsBefore committing to a plan or launch, assume it already failed and reason backward through concrete causes — convert failure paths into mitigations, gates, and stop checks.01 Thinking Probabilistictjboudreaux/cc-thinking-skillsUse when forecasting, estimating, or sizing risk — anchor on base rates, give ranges, update prior→likelihood→posterior on evidence, and factor unmeasured quantities into order-of-magnitude bounds.01 Thinking Red Teamtjboudreaux/cc-thinking-skillsFor authorized security review of code, auth, or APIs you control, model the attacker, map the attack surface, and report only findings with a reproducible exploit path and verified mitigation.01 Thinking Reversibilitytjboudreaux/cc-thinking-skillsBefore heavy deliberation, classify the decision as cheap or costly to undo; decide two-way doors fast and stage one-way doors to preserve options.01 Thinking Scientific Methodtjboudreaux/cc-thinking-skillsWhen a symptom has several plausible causes, rank falsifiable hypotheses and run the cheapest discriminating observation first; prefer least-assumptive survivors only after evidence fit.01 Thinking Second Ordertjboudreaux/cc-thinking-skillsWhen a change has effects past the immediate fix—incentives, scale, feedback—trace consequence chains with timing and probability before committing.01 Thinking Socratictjboudreaux/cc-thinking-skillsWhen a request is vague, assumption-laden, or "obvious," ask the few load-bearing questions that expose hidden requirements before building or committing.01 Thinking Steel Manningtjboudreaux/cc-thinking-skillsBefore rejecting a proposal or reflexively agreeing, build the strongest faithful opposing case, state agreement conditions, then update or reaffirm.01 Thinking Systemstjboudreaux/cc-thinking-skillsWhen behavior is emergent across components—fixes elsewhere break, loops/delays dominate—map boundary, stocks/flows, feedback, archetypes, then rank leverage.01 Thinking Theory Of Constraintstjboudreaux/cc-thinking-skillsWhen throughput or latency is pipeline-limited, identify the single binding constraint and exploit, subordinate, elevate, then recheck—ignore non-constraints.01 Thinking Thought Experimenttjboudreaux/cc-thinking-skillsWhen a real test is too rare, large, or irreversible, run a controlled counterfactual: isolate one variable, fix conditions, trace the mechanistic chain, and bound what the result implies.01 Thinking Triztjboudreaux/cc-thinking-skillsWhen two design requirements seem mutually exclusive, name the contradiction, separate conflicting states, then invent a concrete no-compromise resolution.01 Thinking Via Negativatjboudreaux/cc-thinking-skillsUse when the reflex is to add a feature, layer, or process. Prefer removing harmful or nonessential elements first, with an irreversibility guard before deletion.01
