The registry of
verified knowledge
for AI agents.

pax — Portable Analytic eXpertise — is a knowledge format that bundles constructs, findings, propositions, sources, and analytical playbooks into a single inspectable folder. Hand one to an agent, and it reasons with the field's evidence, not the model's vibes.

// anatomy of a pax
One folder. Inspectable forever.
A pax is a folder of YAML and JSON, not a service. You can read it. You can fork it. You can grep it.
spec v2.0
C
Constructs
constructs.json

Variables and concepts: gdp_per_capita, conflict_onset, cap_rate. Each typed (quantifiable, categorical, outcome) with units.

F
Findings
findings.json

Empirical claims with effect size, standard error, p-value, sample size, and study design — directly grounded in sources.

S
Sources
sources.json

Underlying papers, datasets, reports. DOIs, design type, sample size — the evidentiary backing.

P
Propositions
propositions.json

Theoretical, methodological, and empirical claims that span findings — the field’s “rules of thumb.”

B
Playbooks
playbooks/quick_start.yaml

Step-by-step analytical recipes (YAML) that an MCP-aware agent can execute end-to-end.

// how pax scale
Five pax types.
From a single paper to an entire field. Not every problem needs a 50-pax index. Sometimes you just need one paper.
P
paper
A single peer-reviewed study, systematically extracted into constructs and findings.
5–15 constructs · eg. deforestation-tropics
T
topic
A coherent literature across several papers, unified by a research question.
15–50 constructs · eg. minimum-wage
F
field
A complete sub-discipline with canonical constructs, contested findings, and cross-topic propositions.
50+ constructs · eg. health-disparities
E
enterprise
Private proprietary constructs and findings, curated for a specific organizational context.
varies · eg. commercial-real-estate
X
engine
A reusable analytical method: statistical engines, playbook templates, and inference scaffolds.
method-first · eg. panel-id
// the bridge problem
Independently authored. Joinable on shared constructs.
When two pax declare the same construct id, an agent can reason across both. Today the registry has 6 registered bridges — all between two materials-science pax. As more pax publish, bridges will emerge across domains.
see all bridges →
registered bridge · formation_energy_per_atom
Stability prediction across DFT databases and ML potentials.
bartel-comp-materials ml-materials-discovery
88 findings reference this construct
registered bridge · gnn_interatomic_potential
Where DFT-validated stability survives ML screening.
bartel-comp-materials ml-materials-discovery
14 findings reference this construct
registered bridge · discovery_acceleration_factor
Quantifying ML's screening speedup over random baselines.
bartel-comp-materials ml-materials-discovery
10 findings reference this construct

Publish your expertise.

PAX is open. Anyone can author and publish. If you have a research finding, a methodology, or a literature review worth structuring — package it as a pax and submit it. After review, it goes live for any AI agent to use.
