Commands are prefixed s4h- — e.g. /s4h-decision. Each domain routes to 4–20 individual methods.
Why a methods layer matters
- Repeatable — the same rigor on any problem, not whatever got improvised.
- Inspectable — you see the moves, not a black box.
- Composable — methods chain: a decision feeds a premortem feeds an incentive map.
- Democratized — the toolkit of history’s finest thinkers, on demand.

/s4h
Describe your situation — it routes to the method. You never need to know which one. Every skill states its read and asks how deep to go before it runs; correct the framing anytime.

See it think — worked examples
Platforms want healthier discourse. Users say they want it. It keeps getting worse. /s4h-systems-feedback-mapping finds the reinforcing loop: engagement-optimised feeds reward content that provokes reaction, which selects for users who engage with provocation, which trains the algorithm to serve more of it. The stated goal and the actual incentive structure point in opposite directions. No individual decision made it this way — the system produced it.
The ethics and game theory of automating 40 jobs
Your company is considering automating a function that currently employs 40 people. /s4h-ethics-council runs five frameworks and surfaces a genuine conflict: utilitarian logic favours the automation, Kantian reasoning flags that treating displaced workers as means rather than ends requires more than an efficiency argument. /s4h-game-theory-mechanism-design then helps design a transition that aligns incentives — rather than announcing a decision and managing the fallout.
Why a new pricing model keeps failing despite making economic sense
The economics look clear: the new pricing model captures more value, aligns incentives, and is objectively fairer. It keeps getting rejected. /s4h-economics-incentive-mapping finds the problem: the people who must approve it face short-term losses even though the organisation wins long-term. /s4h-economics-coordination then diagnoses the collective action failure — each approver is waiting for someone else to absorb the transition cost first.
Why a product keeps winning technically and losing commercially
Engineers ship a product that outperforms competitors on every measurable dimension. It keeps underperforming in the market. /s4h-design-user-needs finds the gap: the features being optimised are the ones engineers care about, not the ones that determine adoption decisions. /s4h-cognition-mental-models then surfaces the mental model users bring to the product — and shows the product is being built against a different model than the one users actually hold.
A consumer app hit 100,000 users fast, then plateaued. Growth tactics aren’t working. /s4h-network-effects diagnoses the type of network effect at play — local, not global — which means the platform reaches saturation within clusters long before it reaches market saturation. /s4h-network-weak-ties then identifies the bridge connections that could carry growth across cluster boundaries.
What a startup’s fundraising pitch is actually communicating
A founder’s pitch deck is clear and well-structured. Investors keep passing without giving substantive reasons. /s4h-linguistics-framing finds the issue: the deck frames the company as solving a problem investors already think is solved, which pre-loads skepticism before a single number is scrutinised. The facts haven’t changed — the frame has been working against the argument the whole time.
The political landscape through game theory
The current political climate feels like everyone is acting against their own interests. /s4h-game-theory-iterated maps the repeated-game structure: parties face short-term defection incentives even when cooperation would benefit everyone long-run, and a shrinking shadow of the future (declining expected gains from future cooperation) explains why moderation keeps losing even when most people say they want it. The equilibrium is stable — not because of irrationality, but because of it.
Whether the current wave of nationalism is unprecedented
The political nationalism of the 2020s feels like something new. /s4h-historical-cycle-detection finds four structural analogues — late-19th-century nativist movements, 1930s economic retrenchment, post-colonial identity politics, 1970s stagflation politics — and maps where the current situation matches the pattern and where it doesn’t. More useful than “this has happened before” or “this time is different.”
A career pivot with a closing window
You’re considering leaving a stable senior role for an early-stage company. The question feels like yes or no. /s4h-strategy-positioning maps how your options change if you wait two years versus going now. /s4h-decision-reversibility-analysis finds the move is partially reversible in the medium term — but with a specific window that closes as you get further from hands-on execution. The pairing surfaces a time constraint neither skill would have found alone.
Whether a dominant tech company’s position is actually durable
The company looks unassailable: massive market share, capital, talent. /s4h-ecology-keystone-species maps the dependencies — which other players rely on it and which the platform itself relies on — and finds two suppliers with quietly disproportionate leverage. /s4h-ecology-succession then models what the ecosystem looks like in the next developmental stage, and whether the current dominant player is positioned for it or optimised for conditions that are already passing.
How a species analogy reveals the flaw in a market entry strategy
A company plans to enter a mature market by doing what the market leader does, but cheaper. /s4h-evolution-fitness-landscape maps the landscape: the incumbent occupies a local optimum that is genuinely hard to displace incrementally — competing on the same dimensions means fighting on the incumbent’s terms. The analysis points toward a different peak entirely: a niche the incumbent has structurally abandoned.
A team drowns in data but keeps making the same avoidable mistakes. /s4h-information-signal-noise finds that the most decision-relevant signals are buried in low-frequency, low-urgency reports that nobody reads — while high-frequency, high-urgency signals (email, Slack, dashboards) carry almost no information about the actual problem. The team isn’t uninformed; it’s overloaded with noise while the signal sits unread.
Where to reach for what
Decisions — /s4h-decision for structure, /s4h-decision-premortem-analysis to stress-test before committing, /s4h-constraint-hardness-testing to separate real obstacles from assumed ones.
Complex situations — /s4h-systems to map why something keeps producing the same outcome, /s4h-game-theory for the incentive structure underneath, /s4h-historical for the pattern it’s an instance of.
Creative work — /s4h-creativity-brainstorm for multi-method exploration, /s4h-constraint-rule-inversion to make limits generative, /s4h-aesthetic-elegance-testing to find what’s unnecessary.
Communication — /s4h-communication-objection-mapping to anticipate resistance, /s4h-narrative-tension-mapping to find what earns attention, /s4h-writing-rhetoric to audit what a piece is actually doing.
Ethics — /s4h-ethics-check for a fast multi-framework scan, /s4h-ethics-council for adversarial analysis, /s4h-identity-values-clarification to test against what you actually value.
Investigation — /s4h-investigation-triangulation for independent corroboration, /s4h-investigation-source-trace to trace a claim to its origin, /s4h-investigation-counter-hypothesis to pressure-test your explanation.

Quick examples — one per domain
/s4h-logic
You believe working from home makes you more productive because you get more done on those days. /s4h-logic-check finds the flaw: you only work from home when you have focused work scheduled anyway — the variable you think is causing the effect is just correlated with it.
/s4h-probability
A doctor tells you a test for a rare disease is 99% accurate and you tested positive. /s4h-probability-base-rate-anchoring shows why you’re probably still fine: when the disease affects 1 in 10,000 people, even a highly accurate test produces mostly false positives.
/s4h-decision
You’ve been offered a chance to move abroad for a year. It feels like a binary yes/no. /s4h-decision-option-mapping surfaces four options you weren’t considering: go for six months, negotiate remote work, defer by a year, or go with a return clause.
/s4h-constraint
You want to write a novel but insist you have no time. /s4h-constraint-hardness-testing asks whether the constraint is real — and finds it’s a habit dressed as a fact. The actual constraint is that you haven’t protected a 45-minute slot.
/s4h-game-theory
You and a housemate both hate cleaning the kitchen but neither wants to go first. /s4h-game-theory-prisoners-dilemma shows why this equilibrium is stable and what actually breaks it: not goodwill, but a credible commitment mechanism.
/s4h-epistemology
Everyone in your social circle agrees on a contested topic and it feels like obvious truth. /s4h-epistemology-epistemic-status maps how much of your belief rests on actual evidence versus social contagion — and which parts would survive if your environment were different.
/s4h-investigation
You’ve heard that people only use 10% of their brain. /s4h-investigation-source-trace traces the claim back to its supposed origin and finds no credible scientific source — it appears to have emerged from a misquote and spread through repetition.
/s4h-economics
Your company is subsidising a service that everyone uses but nobody values. /s4h-economics-opportunity-cost maps what that budget forecloses — and finds the invisible cost is three times larger than the visible one.
Your team produces weekly status reports that nobody reads. /s4h-information-entropy measures how much genuine new information each report contains — and finds it’s near zero, because everything in the report was already known by the people receiving it.
/s4h-cognition
A senior engineer keeps making the same class of architecture mistake across different projects. /s4h-cognition-mental-models surfaces the model driving the decisions — and finds it’s a model built for a context that no longer applies.
/s4h-creativity
You’ve been writing the same kind of music for three years and everything sounds the same. /s4h-creativity-lateral-thinking forces you to approach the next track as if you were scoring a silent film — and the constraint breaks the pattern.
/s4h-analogy
You’re struggling to explain how machine learning works to someone with no technical background. /s4h-analogy-domain-transfer imports the structure of learning to ride a bike: you don’t study the physics, you fall, adjust, and eventually your body just knows.
/s4h-play
Your short story feels predictable but you can’t see where. /s4h-play-worst-case-reversal asks you to design the most boring possible version of the story — and the list of failure modes reveals exactly what the current draft is doing.
/s4h-evolution
A competitor keeps copying your product features and you keep losing the advantage. /s4h-evolution-arms-race maps the escalation dynamic — and finds you’re both locked into a cycle neither side can exit unilaterally, optimising for a dimension that neither side actually wants to compete on.
/s4h-design
You’ve shipped five versions of a feature and users still find it confusing. /s4h-design-user-needs separates what users asked for from what they actually need — and finds the confusion is downstream of a mismatch between the feature’s mental model and the user’s.
/s4h-communication
You sent a message that was meant to be supportive and the other person felt criticised. /s4h-communication-clarity-audit finds the two sentences that read as judgement to the receiver even though they weren’t written that way.
/s4h-social
A group project has stalled and nobody can explain why. /s4h-social-dynamics-analysis identifies that one person holds informal veto power over decisions and everyone else is routing around them without naming it.
/s4h-emotional
A close friend keeps cancelling plans at the last minute. /s4h-emotional-resistance-diagnosis maps what might be underneath the behaviour — not flakiness, but something they’re avoiding that the plans surface.
/s4h-ethics
You found someone’s wallet containing a significant amount of cash and no ID. /s4h-ethics-council walks through five ethical frameworks and finds they mostly converge — with one genuinely dissenting position that’s worth taking seriously.
/s4h-identity
You keep agreeing to commitments that make you miserable. /s4h-identity-values-clarification surfaces the gap between what you say you value and what your decisions actually reveal — and names the value that’s been running your choices without your endorsement.
/s4h-narrative
You’re giving a speech that matters to you but it keeps landing flat in rehearsal. /s4h-narrative-tension-mapping finds that you’ve removed all the stakes in an attempt to sound measured — and that’s exactly what’s killing it.
/s4h-psychology
You’ve tried to quit a habit five times and it keeps returning. /s4h-psychology-behavior-change diagnoses what’s maintaining it: not lack of willpower, but a specific trigger-routine-reward loop that none of your previous attempts addressed.
/s4h-mindset
You’ve been dreading a difficult conversation for three weeks and it’s getting worse. /s4h-mindset-stoic separates what’s in your control from what isn’t — and finds the avoidance is costing more than the conversation would.
/s4h-writing
Your essay makes a strong argument but readers say it doesn’t land. /s4h-writing-rhetoric reveals the structure leads with the conclusion before earning it — the reader hasn’t been brought along, so the argument feels asserted rather than demonstrated.
/s4h-linguistics
Your policy proposal keeps getting mischaracterised in discussion. /s4h-linguistics-framing finds the word you chose to describe the mechanism carries a connotation that pre-loads opposition — a different word, identical in denotation, removes the friction.
/s4h-systems
Every time your team fixes one problem, two more appear. /s4h-systems-feedback-mapping finds the reinforcing loop: the fixes are creating conditions that generate the next set of problems faster than the team can resolve them.
/s4h-temporal
You’re deciding whether to go back to study and the short-term cost feels prohibitive. /s4h-temporal-horizon-mapping maps the decision at one year, five years, and twenty — and shows that the framing that makes it look impossible only holds at the shortest horizon.
/s4h-historical
You’re starting an ambitious creative project and feel pressure to have a breakthrough immediately. /s4h-historical-failure-analysis maps how most significant creative works actually developed: slowly, with long unproductive stretches that looked like failure until they weren’t.
/s4h-resource
You have three hours to prepare for an important conversation and you’re trying to prepare for everything. /s4h-resource-bottleneck-analysis finds the real constraint: there are two specific questions you can’t answer and everything else is already solid.
/s4h-strategy
You want to win a local chess tournament. /s4h-strategy-positioning shows that the decisive work happens before the match: in the openings you prepare, the players you study, and the psychological state you arrive in.
/s4h-network
You’ve been trying to break into a new industry for a year with no traction. /s4h-network-weak-ties maps your current network and finds it’s dense but homogeneous — everyone you know already knows everyone else. The entry point is a single weak tie to a different cluster, not another strong tie in your existing one.
/s4h-ecology
Your product’s ecosystem of integrations looks healthy until two partners quietly announce they’re building competing features. /s4h-ecology-interdependence maps the dependency web and finds three other integrations that were implicitly relying on those two partners — a cascade that wasn’t visible until the dependencies were drawn out.
/s4h-aesthetic
Your apartment feels wrong but you can’t articulate why. /s4h-aesthetic-coherence-check finds that three incompatible design eras are competing in the same room — and the feeling of wrongness is the parts refusing to form a whole.
/s4h-sensory
You’ve read the same paragraph four times and nothing is sticking. /s4h-sensory-signal-detection asks what’s actually present in your environment right now that you’ve stopped registering — and finds three things competing for the same attention channel.
