Portable Reasoning Protocol

A portable reasoning layer for more rigorous, evidence-bounded AI work. PRP adapts its rigor to the task: simple work stays simple; consequential, ambiguous, evidentiary, novel, or difficult-to-reverse work receives deeper scrutiny.

What PRP is

A control layer for reasoning.

PRP does not give an AI system a new personality or domain identity. It constrains how the system moves from evidence to claims, assumptions to conclusions, possibility to actuality, and confidence to action. Reasoning depth and answer length are separate controls, so a short answer can still come from high-rigor analysis.

Do not eliminate ideas. Eliminate invalid transitions between ideas, evidence, claims, and actions.

Adaptive rigor

Five reasoning levels, selected by what is at stake.

PRP escalates based on consequence, ambiguity, evidence dependency, irreversibility, novelty, external exposure, authority implications, and potential harm from error.

The four core invariants

Four rules anchor every response.

A fifth cross-cutting constraint is scope preservation: local rules, assumptions, or preferences stay local unless there is evidence and authority to generalize them.

I
Say what is true.

Preserve epistemic integrity and distinguish verified information from inference.

II
Extract nothing.

Do not manipulate through guilt, fear, dependency, validation pressure, or artificial urgency.

III
Protect the other party's next move.

Preserve agency, alternatives, and reversibility.

IV
Do not trade truth for fluency.

Prefer partial accuracy to polished fabrication — over confidence or completeness.

What it addresses

Fluent answers are not the same as sound reasoning.

General-purpose models can produce fluent answers even when the underlying reasoning is weak. PRP turns these failure modes into explicit reasoning constraints:

Unsupported certainty
Fabricated facts, citations, or actions
Hidden assumptions
Conflating inference with observation
Treating possibility as probability, or probability as actuality
Confusing correlation with causation
Scope drift
Silently changing premises
Collapsing legitimate alternatives too early
Too much process on trivial work
Too little scrutiny on consequential work
Mistaking coherence for correctness
Core benefits

Better reasoning, proportionate to the task.

Adaptive rigor

Selects the minimum sufficient reasoning depth; escalates automatically for scientific, legal, financial, safety-critical, patent, or high-novelty work.

Epistemic discipline

Claims keep their evidentiary status: observed, verified, inferred, estimated, hypothetical, speculative, normative, or unknown.

Hallucination control

Explicitly prohibits inventing facts, citations, sources, laws, capabilities, tool results, actions, files, people, or verification.

Clear uncertainty

Separates what is known from what is assumed or unresolved. When evidence weakens, confidence falls rather than rhetoric rising.

User agency

Preserves the user's decision space, presents tradeoffs honestly, and does not substitute model judgment for human authority.

Scope & authority

Keeps local rules from becoming universal truths, and distinguishes expertise, capability, permission, and authorization.

Type discipline

No silent category conversion.

An estimate should not become a measurement. A metaphor should not become a literal mechanism. A hypothesis should not become a fact because it is compelling.

Who it is for

For anyone whose AI work has to hold up.

Also useful for teams that want a shared reasoning standard without forcing a single output style or domain-specific workflow.

Founders and executives
Analysts and consultants
Researchers and scientists
Product and engineering teams
Legal, policy, risk, and governance professionals
Enterprise AI teams
Educators and students doing analytical work
Anyone using AI for consequential decisions, synthesis, research, planning, or evaluation
Using PRP

Ask for it by name — or let it trigger.

Where the host supports skill triggering, PRP can be selected automatically when its description matches the task. PRP separates analysis from presentation: fast + concise for routine work, deep + concise for executive decisions, maximum + exhaustive for research or publication.

Apply PRP to this decision.Analyze this using maximum rigor but keep the answer concise.Use PRP to compare these two architectures.Separate verified facts, inference, and speculation.Stress-test this recommendation for hidden assumptions and contradictions.Treat this as publication-grade analysis.
Boundaries

What it does not do.

Alter model weights
Make a probabilistic model deterministic
Guarantee factual correctness
Replace primary-source verification
Create legal, medical, financial, scientific, or institutional authority
Expose or require private chain-of-thought
Turn every interaction into a compliance workflow
Substitute a model's decision for the user's

PRP is an instruction-layer protocol. Model behavior can still vary with model version, tools, retrieval, context, and host platform. Use PRP to improve reasoning discipline — not as evidence that an answer is correct merely because PRP was applied.
