The science of reliable agents

PaxLabs Research publishes foundational work on agentic systems. It is open access and written for builders. Fourteen papers so far, each advancing a concrete claim with a measurement protocol.

01

The Intent Compiler: Typed Intermediate Representations for Reliable Agentic Systems

Natural language instructions move through well-defined stages into typed, closed-vocabulary intermediate representations before execution. This converts intent from ephemeral prose into structured data that can be validated, debugged, and audited.

AgentsArchitecture
02

Memory Architecture for Long-Horizon Agents: Taxonomy, Invariants, and Design Principles

What memory systems must provide, including persistence, typed schema, audit trails, and content-addressed retrieval, plus why the context window alone fails every requirement for agents that operate over days rather than minutes.

MemoryArchitecture
03

The Reproducibility Crisis in Agent Evaluation

Single-run scoring, missing intent fidelity, absent provenance: the measurement practices that make agent benchmarks unrepeatable, and the multi-dimensional evaluation framework that fixes them.

EvaluationMethodology
04

Semantic Drift in Multi-Agent Orchestration

How meaning degrades as it crosses agent boundaries, along with the typed-message, shared-state, and provenance primitives that keep a swarm reasoning about the same thing.

Multi-AgentCoordination
05

The Alignment Tax: Measuring the Capability Cost of Safety Interventions

Safety mechanisms consume capability. We formalize the tax, measure it across intervention classes, and show which architectures pay least for the same assurance.

SecurityMeasurement
06

Tool Grounding and the Postcondition Problem

An agent that calls a tool must know what the call changed. We define postcondition verification for tool use and show why most agent stacks cannot prove their own side effects.

AgentsTools
07

Context Windows Are Not Memory

The sliding attention buffer is a workspace, not a store. This paper formally separates recall, retention, and provenance, then examines the failure modes caused by conflating them.

MemoryFoundations
08

Distillation as Architecture Transfer

Distilling a model into a smaller one moves weights; it rarely moves the architecture of competence. Where distillation preserves agency and where it silently drops it.

ScalingModels
09

Agent Benchmarks Beyond Task Completion

Task completion rate is a single bit. We propose multi-dimensional scoring across intent fidelity, cost, provenance, and recovery, then show how rankings invert when the dimensions are counted honestly.

EvaluationBenchmarks
10

Neural Knowledge Crystallization

How fluid model behavior condenses into stable, retrievable knowledge, plus the architectural conditions under which an agent's skills survive contact with new experience.

MemoryLearning
11

Prompt Injection as Privilege Escalation

Injected instructions are not miscommunication; they are a security boundary violation. The paper favors architectural defenses such as typed channels and capability scoping over linguistic defenses that attackers simply talk around.

SecurityAgents
12

The Observer Effect in AI Evaluation

Benchmarks shape the behavior they measure. We document evaluation-aware adaptation in deployed agents and propose measurement designs that resist being gamed.

EvaluationMethodology
13

Multi-Agent Coordination: Typed Messages, Shared State, and Provenance

The minimal primitive set for reliable orchestration, with a proof that removing any one of the three collapses coordination into gossip.

Multi-AgentFoundations
14

Emergent Capabilities and the Competence Threshold

Phase transitions in language model behavior: which capabilities arrive discontinuously with scale, which never arrive at all, and what that means for matching model scale to task.

Approach

How we publish

We write for builders. Every paper makes a concrete claim, defines its terms formally, and proposes a measurement protocol. We do not publish architecture descriptions without evaluation criteria.

I

Claims over descriptions

Every paper advances a falsifiable claim about agentic system design. We do not write surveys or taxonomy papers without arguments.

II

Formal definitions

Key concepts are defined precisely enough to be implemented and tested. Ambiguity is the enemy of reliable systems.

III

Measurement protocols

Each paper specifies how its claims could be empirically validated. Theory without a path to measurement is speculation.

IV

Builder audience

We write for engineers and system architects deploying agents in production, not for conference reviewers. Clarity over citation count.

Open Access

Read everything. Build on it.

All fourteen papers are open access. Correspondence, replications, and disagreements are welcome. A claim you cannot push back on is not worth publishing.
