REALM: Identifying Minimal Task Assets for LLM Agents

Read the original on arXiv AI →

REALM (Required Execution Assets Linked to a Mission) is a method for identifying and managing the minimal set of assets that a large language model (LLM) agent needs to complete a task, even when those assets are discovered only during execution. It represents required assets as nodes in a dependency graph, separates asset discovery from authorization, and uses a REALM Builder to maintain grants and a Partial API Manager to expose resource‑bound APIs within a task container. In experiments on 60 clean tasks and 560 injected cases, REALM achieved 40.0% task completion and reduced attack success rate from 16.6% to 0.2% when using qwen3.5‑flash as the base model.

Progressive Skill Discovery as Access Control for Tool-Using LLM Agents: Structural Governance through Role-Scoped Capability Delivery

The paper introduces skilder, a framework that organizes LLM agent capabilities into role‑scoped bundles of skills, tools, and instructions, with explicit limits. Agents start with a minimal role catalog, discover the roles needed for a task, and receive the associated tools only through a single MCP server, ensuring deterministic enforcement of scope. Experiments on 13 tasks with six models show that skilder’s authorization layer prevents unauthorized tool calls and parameter violations while maintaining flexibility through dynamic cross‑role capability acquisition.

From LLM Inference to Agentic Workloads: Characterization and Implications for Serving Systems

arXiv:2608. 15127v1 Announce Type: cross Abstract: Agentic applications are shifting AI serving from isolated model inference to long-running workloads in which LLMs coordinate tools, environments, and persistent state.

Action-Space Shaping for LLM Agents: Measuring and Mitigating Tool-Schema Bias

The paper investigates how the representation of tool interfaces—referred to as a tool schema—affects the performance of large language model agents. By systematically transforming a native tool schema with nine operators, the authors demonstrate that agents exhibit significant variability in success rates across different but functionally equivalent schema variants, a phenomenon they call schema bias. Experiments on eleven LLMs, including closed models, reveal that success can range from complete failure to 97% solely due to schema differences, and that training only mitigates bias when the specific variant is included in the training data.
