Agentic Context Management: Solving Agent Memory and Cost by Treating Them as Lifecycle and Architecture Problems

Gaurav Dadhich

his paper argues that AI agent failures stem from poor context management, not reasoning ability. It proposes treating context management as a lifecycle and architectural problem, rather than just storage and retrieval. The core contribution is a framework for actively managing agent memory by considering its entire lifecycle, from deciding what to remember to forgetting, all within budget constraints.

The five-primitive context lifecycle (architecting → \( \rightarrow \) ingesting → \( \rightarrow \) scoping → \( \rightarrow \) anticipating → \( \rightarrow \) compacting & consolidation), drawn as a cycle around a central agent, with the retrieval scope hierarchy (user → \( \rightarrow \) customer → \( \rightarrow \) client) as a vertical axis and the global knowledge layer drawn separately, feeding entity canonicalization.

GradRAG : cross-component prompt adaptation in an agentic RAG pipeline. Grey (forward pass): A Retrieval Agent gathers evidence from either document chunks (Vector RAG) or a structured entity–relation graph (GraphRAG, constructed by a separate agent that is not shown in the mock up), which is assembled into a context and passed to an Answer Generation Agent to produce a candidate answer. Orange (evaluation and control): An Evaluator reviews the answer and its supporting evidence and returns feedback with a binary Stop? decision. If Yes , the answer is accepted. If No , a Prompt Optimizer updates the prompts of one or more agents (as indicated by the evaluation), and the next forward pass is executed.

GRADRAG: Cross-Component Prompt Adaptation for Coordinated Multi-Agent RAG

Paolo Pedinotti, Enrico Santus

GRADRAG introduces a novel framework for optimizing multi-agent RAG systems by coordinating improvements across all components. It models the RAG pipeline as a computational graph and uses structured feedback from an Evaluator to iteratively adapt upstream age…

PATS: Policy-Aware Training Scaffolding for Agentic Reinforcement Learning

Yipeng Shi, Zhipeng Ma et al.

This paper introduces PATS, a novel training method for LLM agents that uses a "policy-aware training scaffold." Instead of focusing on skills, PATS dynamically adjusts the context provided to the agent during training based on its current performance. This sc…

Seed-0 training dynamics on 1.5B ALFWorld under the shared 150-step RL budget. Left: validation success rate. Right: mean prompt tokens per policy call; faint traces are raw logs and bold traces are seven-step moving averages. Pats expands its training context early and later contracts it as validation improves, whereas SkillRL’s context grows and SKILL0 follows staged withdrawal.

A persona subspace present in the model before fine-tuning carries broad misalignment. The subspace is extracted from the frozen instruction-tuned model. Projecting it out of the residual stream throughout fine-tuning prevents broad misalignment (27.7% → \( \to \) 0.0%); adding it to the never-fine-tuned model induces misalignment that grows with dose (to 45.4%); the same projection applied to the weight gradient changes nothing (26.6% vs. 26.7%). Each arm carries a matched random control (Section 5 ).

Emergent Misalignment Recruits a Pre-existing Persona Subspace

Mohammed Suhail B Nadaf

This paper investigates emergent misalignment in language models, where fine-tuning on narrow "bad advice" leads to broad misalignment. The core method reveals that this generalization occurs because fine-tuning activates a pre-existing persona subspace within…

The Dark Room in the Reward Channel: Dense Prediction Rewards Collapse GRPO-Trained LLM Agents -- and What Actually Works

Yu Wang

This paper demonstrates that dense, per-step prediction rewards, intended to aid long-horizon LLM agents, actually cause catastrophic policy collapse under Group-Normalized RL (GRPO). The core issue is that GRPO's z-scoring amplifies the dense signal, leading …

The std-normalized prediction reward collapses every run at all three scales; timing is non-monotonic (saturation race, § 4.5 ). Honeymoon peaks rise with scale: the signal genuinely helps until hacking pressure arrives.
