Reasoning
Use this skill as the entrypoint for evidence-oriented reasoning in ClimbHill. Keep the primitive set small. Prefer composing these primitives into workflows rather than creating a new skill for every product or business technique.
Core rule
Do not spend tokens answering a question that reality can answer cheaply.
Evidence updates the plan; it does not exist to vindicate the route already chosen.
Primitives
- Experiment - design the cheapest credible encounter with reality that can resolve an uncertain assumption.
- Evidence - interpret observations against a hypothesis or decision without defending the current plan.
Other existing skills remain complementary:
research/ deep-research skills: gather facts from external sources.prototype: make a concrete artifact when behavior or design is unclear.- grilling / human-in-the-loop discussion: obtain judgment only the human can supply.
- domain modeling: sharpen concepts and language before deciding.
- task / execution skills: perform mechanical work needed to unblock learning.
Choosing a primitive
Use Experiment when the unresolved question is empirical and a small action can produce evidence. Examples: demand, willingness to pay, usability, runtime behavior, benchmark performance, reliability, or whether a user will complete a workflow.
Use Evidence when observations already exist but their implications are unclear. Examples: experiment results, user interviews, benchmark output, production telemetry, test results, incident logs, or sales outcomes.
Use research instead when the answer already exists in trustworthy sources. Use a prototype when the main uncertainty is what a proposed interaction or design should be like rather than whether a claim about reality is true.
Workflows
Common compositions live in workflows/:
- Discover - find the real job and current solution landscape, then identify opportunities.
- Bet - generate a small number of genuinely different bets before converging.
- Smoke Test - test the promise before building the machinery.
- Value Path - shorten the path from first contact to realized value and test it cheaply.
- Falsify - actively try to kill an important assumption or the whole plan before investing further.
These are workflows, not additional primitives. They may call research, prototype, Experiment, Evidence, domain modeling, implementation, and human judgment as needed.
Wayfinder relationship
Wayfinder determines which uncertainty matters next. Reasoning determines how to attack that uncertainty. A workflow may resolve one Wayfinder ticket or expose new tickets, but should not replace Wayfinder's map, frontier, dependency, or scope semantics.
