Five composable motions
Reduce to bedrock, pick the simplest fit, trace where it leads, invert to find what kills it, and update as evidence arrives. Each skill stands alone — together they compose.
First Principles
Strip a problem to statements that can't be reduced further — physical law, definition, cited fact — then rebuild the answer using only those.
Worked example: The Wright Brothers, 1901
View source & install →Occam's Razor
When several explanations all fit the evidence, prefer the one that assumes the least. A selection heuristic for what to bet on first.
Worked example: Wegener & continental drift, 1912
View source & install →Second-Order Thinking
First-level thinking asks “what happens?” Second-order asks “…and then what?” — catching the effect that reverses the obvious one once everyone responds.
Worked example: US Prohibition, 1920
View source & install →Inversion
Instead of “how do I win?”, ask “how could this fail catastrophically?” — then design the plan around eliminating the failure paths that matter most.
Worked example: Apollo 1 FMEA, 1967
View source & install →Bayesian Reasoning
Posterior odds = prior odds × likelihood ratio. Belief after evidence equals belief before, times how diagnostic the evidence actually is.
Worked example: The Sally Clark case, 1999

Circle of Competence
Know where your judgment is reliable and where it isn't — stay inside the circle, and widen it deliberately.
View source & install →Margin of Safety
Commit far enough below your estimate of worth that even a wrong estimate still leaves you safe.
View source & install →Opportunity Cost
The real cost of any choice is the next-best thing you gave up — not what you paid.
View source & install →Pre-Mortem
Assume the plan already failed catastrophically, then work backward to name the causes — before you commit.
View source & install →Pareto Principle (80/20)
A small fraction of inputs produces most of the output. Find the vital few; ignore the trivial many.
View source & install →Regret Minimization
For large, irreversible, life-defining choices, pick the path you'll least regret — not the highest EV.
View source & install →Chesterton's Fence
Before you remove a rule or process, understand why it was built. Only then are you fit to judge it.
View source & install →Compound Interest
Small consistent growth compounds into astonishing long-run results — in capital, skill, and reputation.
View source & install →Confirmation Bias
We seek and weight evidence that confirms what we already believe. Hunt for what would prove you wrong.
View source & install →Sunk-Cost Fallacy
Money and effort already spent are gone. Decide only on the marginal cost and benefit from here forward.
View source & install →MECE
Break a problem into parts that are mutually exclusive and collectively exhaustive — no overlaps, no gaps.
View source & install →Economic Moat
The durable structural advantage that keeps competitors from competing your returns away.
View source & install →Porter's Five Forces
Industry profitability is set by five forces — rivalry, buyers, suppliers, entrants, and substitutes.
View source & install →Jobs to Be Done
People don't buy products; they hire them to make progress in a circumstance. Find the job.
View source & install →Lean Startup
A startup searches for a repeatable business model. Test the riskiest assumption before you scale it.
View source & install →Minimum Viable Product
An MVP isn't a small product — it's the smallest test that yields trustworthy evidence about one assumption.
View source & install →Network Effects
Some products get more valuable the more people use them. Map the loop; defend the cold start.
View source & install →Antifragile
Beyond robust: systems that gain from disorder. Cap the downside, leave the upside open.
View source & install →Black Swan
Rare, extreme, explained-only-in-hindsight events dominate outcomes. Build for the tails you can't predict.
View source & install →Map Is Not the Territory
Every metric, model, and deck is a simplified, aging abstraction. Don't confuse it with reality.

Most AI runs the work. deciqAI runs the thinking before it.
These skills are open source because rigor should be. But a skill is only a method — deciqAI is the operator team that runs them autonomously: 50+ specialist agents, each wired with 160+ skills, that launch your site, fill your pipeline, watch your cash, and think before the calls that decide the company.
