Each skill is a complete procedure: a defined problem type, a sequence of moves, a structured output. Not a concept to apply — a method to run.

Every skill pauses before running and asks how deep you want to go.

Think Sharper
/logic
/logic— Entry point for the logic toolkit./logic-argument-validation— Check whether an argument's premises actually support its conclusion, and identify logical fallacies./logic-causality-mapping— Map causal relationships, trace dependencies, and reason about consequences before acting./logic-check— A fast, comprehensive logic report on any argument, plan, or reasoning — validates premises, tests inference, detects fallacies, surfaces hidden assumptions, and produces a verdict./logic-consistency-check— Surface internal contradictions, conflicting requirements, and edge cases that expose hidden conflicts in a document, spec, plan, design, or set of requirements./logic-constraint-mapping— Map the full constraint landscape for a decision, design, or plan — distinguishing hard limits from soft preferences, surfacing hidden constraints, and finding conflicts between them./logic-council— Run a reasoning problem, argument, plan, or decision through a council of 5 logical reasoning advisors who analyze it from distinct reasoning frameworks, peer-review each other, and synthesize a verdict on whether the reasoning holds.
/probability
/probability— Entry point for the probability toolkit./probability-base-rate-anchoring— Anchors estimates in historical base rates before adjusting for specific factors./probability-confidence-calibration— Tests whether stated confidence levels match available evidence — catching overconfidence and underconfidence./probability-expected-value-calculation— Calculates expected value to compare options under uncertainty./probability-scenario-weighting— Assigns explicit probabilities to distinct scenarios before making a decision.
/decision
/decision— Entry point for the decision toolkit./decision-criteria-weighting— Runs a weighted multi-criteria analysis — making explicit what matters, how much, and how each option performs against it./decision-option-mapping— Ensures all real options are visible before choosing — countering the false dichotomy that limits consideration to the first two options that came to mind./decision-premortem-analysis— Imagines the decision has been made and failed — then diagnoses why./decision-reversibility-analysis— Categorises a decision by reversibility and applies the appropriate level of process rigour.
/constraint
/constraint— Entry point for the constraint toolkit./constraint-hardness-testing— Tests whether a stated constraint is real — distinguishing genuine limits from assumptions, habits, or politics dressed as facts./constraint-rule-inversion— Flips a constraint into a creative driver — uses the limit as the generative force rather than working around it./constraint-scope-reduction— Finds the minimum that satisfies the actual requirement — stripping everything wanted but not needed./constraint-workaround-mapping— Finds paths around a fixed constraint without removing it — routing around a hard limit to reach the same goal.
/game-theory
/game-theory— Routes to the right game-theory skill for your strategic situation./game-theory-auction— Analyses bidding strategy and auction design — how much to bid, how to avoid the winner's curse, and how to design revenue-maximising or efficient auctions./game-theory-coalition— Analyses which coalitions form and how to divide gains fairly using cooperative game theory and the Shapley value./game-theory-equilibrium— Finds the stable outcome of a strategic interaction — the point where no player can improve their result by changing their strategy alone./game-theory-iterated— Analyses long-run repeated interactions — how cooperation forms, how trust is built, how defection spirals start, and which strategies sustain cooperation./game-theory-mechanism-design— Designs rules and incentive systems that produce desired outcomes even when players are self-interested./game-theory-prisoners-dilemma— Analyses cooperation problems where individual rationality produces collective irrationality./game-theory-signaling— Analyses credibility problems and designs signals that are believable because they're costly to fake.

/investigation
/investigation— Entry point for the investigation toolkit./investigation-claim-decomposition— Breaks a complex claim into its smallest independently verifiable parts, classifies each sub-claim, and identifies which parts carry the most logical load./investigation-counter-hypothesis— Generates the best alternative explanations for the same observations./investigation-evidence-audit— Evaluates the quality, strength, and completeness of evidence for a claim./investigation-source-trace— Traces a claim back to its origin: who first made it, what evidence it rested on, and how it has been distorted in transmission./investigation-triangulation— Verifies a claim across genuinely independent sources, distinguishing amplification from true corroboration.
Think Differently

/play
/play— Entry point for the play toolkit./play-constraint-inversion— Removes or inverts the main constraint to see what becomes possible — then uses those unconstrained solutions to find real ones./play-perspective-reversal— Fully inhabits the opposing perspective — competitor, critic, user, or adversary — to find what is invisible from your own position./play-stimulus-generation— Introduces a random, unrelated element to break mental fixation — forcing new associations that bypass the groove of familiar thinking./play-worst-case-reversal— Deliberately designs the worst possible version — then reverses each failure mode into a design principle.

/psychology
/psychology— Entry point for the psychology toolkit./psychology-behavior-change— Diagnose what's maintaining an entrenched behavior and design the right intervention to shift it./psychology-cognitive-biases— Diagnose which cognitive biases are actively distorting thinking in a specific situation./psychology-heuristics— Assess the fast-thinking pattern at work — when it's reliable, when it misleads, and whether to trust or override it./psychology-motivation— Diagnose what's actually driving behavior — the person's own, someone else's, or a group's./psychology-persuasion— Identify the right influence approach and construct it for the context.
/mindset
/mindset— Entry point for the mindset toolkit./mindset-flow— Applies Csikszentmihalyi's flow framework to diagnose why optimal experience isn't occurring and redesign the conditions for it./mindset-growth— Applies Carol Dweck's growth mindset research as a practical methodology — the actual mechanics, not the motivational poster version./mindset-positive— Applies positive psychology as a rigorous practice — not pop-psychology positivity./mindset-reframe— Applies cognitive reframing as a rigorous methodology — CBT-adjacent but not therapy./mindset-stoic— Applies the full Stoic toolkit as a practical thinking methodology.

/resource
/resource— Entry point for the resource toolkit./resource-allocation-analysis— Distributes limited resources across competing needs — making the trade-offs explicit rather than implicit./resource-bottleneck-analysis— Identifies what is actually constraining throughput — using Theory of Constraints logic: the system can only move as fast as its slowest point./resource-leverage-mapping— Finds the highest-leverage use of available resources — where the same input produces the most output./resource-waste-audit— Finds where resources are being lost, duplicated, or underused — the seven wastes applied to knowledge work.
