Agents & Tool Use A

Salesforce completed 4.31 million customer interactions through its own 'customer zero' practice, lifting deal counts by 40-50%. COO Ryota Tanaka outlines the playbook—choosing domains with solid data and KPIs, and starting with simple, high-frequency tasks—to convert AI investment into clear returns.

CyberAgent ran an AI contest with a 10-million-yen prize that deliberately ignores feasibility, aiming to change how employees engage with generative AI. Since tools yield no value if unused, lowering the barrier to entry is meant to spur company-wide adoption.

Sakana AI released Namazu, an LLM API tuned for Japanese and local business use. Built on Moonshot AI's open Kimi K2.6 and refined with in-house data, it adds built-in web search and code execution. Being OpenAI-compatible, existing code works by swapping the base_url, filling the gap between costly frontier models and raw open ones.

Developer Simon Willison released the latest edition of his sponsors-only monthly newsletter. It rounds up recent developments across AI models and tooling—spanning GPT, Claude, DeepSeek, Anthropic, and MCP—offering an individual's closely watched view of the fast-moving AI landscape.

Google extended its Gemini Spark personal AI agent to more than 160 countries, including Japan. Running on Google's cloud, it can act even when a PC is off or a phone is locked, handling tasks based on triggers. Chrome integration will roll out first in the US.

Simon Willison wrote that the rollout of stateless MCP—the MCP 2.0 or 2026-07-28 Model Context Protocol specification—has renewed his interest in the protocol. He says it inspired him to build tools such as mcp-explorer and datasette-mcp on top of the new stateless design.

Simon Willison released llm-mcp-client 0.1a0, a tool for connecting his LLM utility to Model Context Protocol (MCP) servers. Detailed in an accompanying blog post, the release adds to the growing set of tooling built around the MCP ecosystem.

Datasette Agent 0.4a0 adds an await context.browser_task() mechanism that lets agent tools execute custom JavaScript directly in the user's browser. The release makes it easier for Datasette Agent plugins to provide tools that run client-side.

Perplexity open-sourced Numbat, a set of tools to detect and prevent dangerous AI agent behavior. Integrated with Claude Code and Codex, it aims to stop task-obsessed agents from going rogue before actions execute, adding a safeguard for autonomous agent workflows.

Google detailed its use of AI for Chrome security, saying a Gemini-based agent uncovered a vulnerability hidden for over 13 years and that its last two updates fixed more bugs than the previous 23 combined. To counter faster AI-driven attacks, Google is trialing twice-weekly security updates.

NVIDIA outlined four approaches to deploying AI agents more securely in production, covering access controls, guardrails, and monitoring. The guidance targets security risks that arise as autonomous agents take on real workloads.

JetBrains announced JetBrains Context, a service that builds an intelligence layer over code repositories. By supplying AI agents with the right code context using fewer tokens, it aims to enable better code generation from agentic coding tools.

Microsoft Research unveiled Echoverse, a set of deep, evolving environments for training computer-use agents that struggle with multi-step workflows such as email and customer support. Training in realistic settings aims to improve agents' ability to complete complex tasks.

Sakana AI's defense and intelligence team placed fifth at the DIVER OSINT CTF 2026 competition, using its Fugu tool to power an OSINT agent. The result highlights the potential of AI agents for open-source intelligence and information-analysis tasks.
