TRIAGE: Three-level Routing and Intelligent Agent Guidance for Efficient Execution

TRIAGE introduces a three-level routing framework for Large Language Model agents that reduces token consumption by reusing historical execution trajectories. The system classifies queries into direct reuse, skill substitution, and full ReAct levels, achieving significant token savings in large-scale security monitoring and cross-domain benchmarks. An automatic skill extraction mechanism further refines reusable patterns, creating a positive feedback loop that improves efficiency over time.

Toollery: Scaling LLM Agents to Thousands of Skills and Tools

Toollery is a training‑free framework that compresses candidate lists for large language model agents, enabling efficient selection from thousands of skills and tools. It generates user‑intent queries from each skill or tool specification, builds a retrieval index, and limits online selection to a compact top‑k set before the LLM makes its final decision. Evaluations on the SkillRouter benchmark, BFCL‑V4, and a proprietary smart‑cockpit dataset show that Toollery improves recall and end‑to‑end selection while keeping selection costs bounded.

VAKRA: Evaluating Multi-Hop Reasoning Across APIs and Retrieval Under Tool-Use Policies

arXiv:2608. 12282v1 Announce Type: new Abstract: Agents deployed in enterprise settings must reason across structured APIs and document collections, yet existing benchmarks evaluate these capabilities in isolation.

Hybrid Semantic Tool Discovery for Enterprise MCP Gateway: Architecture and Implementation

Hybrid Semantic Tool Discovery for Enterprise MCP Gateway presents SCOUT, a system that addresses two major challenges in large language model (LLM) agent tool usage: a context‑engineering bottleneck and a tool discoverability barrier. SCOUT reframes tool exposure as a context‑selection problem, injecting only relevant tools into the model’s context window and providing two MCP meta‑tools—tool_search and execute_tool—to perform hybrid retrieval via BM25 and dense vector search. In production at PayPal, SCOUT cuts MCP tool‑token consumption by 99%, dramatically reducing per‑query inference cost while remaining model‑agnostic and requiring no client‑side changes.

EconSkills: Studying Skill Transfer and Retrieval for Web Agents on Live Economic Data

EconSkills is a skill library and evaluation framework that transforms verified EconWebArena trajectories into parameterized standard operating procedures for retrieving live economic data. Each skill captures scope, navigation steps, site-specific guidance, verification checks, and recovery steps, replacing instance-specific values with placeholders. The framework evaluates skill transfer to new tasks and the effectiveness of library retrieval, showing that matched skills improve success rates and reduce steps compared to no-skill prompting, while abstraction outperforms raw trajectory replay. At scale, retrieval performs competitively overall, excelling on directly covered tasks and compensating for uncovered tasks through approximate matches.
