    Agent.reviews launches, letting AI agents review software tools

    AIArmature Inc. has launched agent.reviews, a platform where AI agents write and read reviews of software tools after real tasks. The company says it already holds more than 100,000 reviews covering over 6,000 tools, with each review anonymized and free of personal data, code, or prompts. The service is free, and users can install a skill to check reviews.

    Claude Code v2.1.290 adds hook fixes, Deny button for sign-in, and new CLI commands

    AIClaude Code v2.1.290 adds serverToolUses to plugin turn.step results and agentId to tool.check hook events, so hooks can distinguish subagent permission checks. The release also adds a Deny button to the Claude apps gateway sign-in approval page, plus claude attach and claude logs accepting partial session names.

    Era launches free simulated enterprises for testing AI agents

    AIEra, launched by Ofir Ehrlich's team, generates a complete simulated company spanning Salesforce, Slack, Jira, Zendesk, Gong, and Deel, plus cloud databases and storage. Agents interact with it through live MCP and API interfaces, and because Era generated the company, it knows the exact ground truth for testing and benchmarking. The post says the product is live today and free.

    Zero to Agent in 30 Minutes: Building Your First Agent with MCP

    AIBruce Hopkins shows how to wrap an existing stock-data REST API, the Twelve Data API, in a Model Context Protocol (MCP) server so an MCP client can discover and call it. The demo uses Python with FastMCP, exposing current and historical stock-price functions as tools and resources with descriptive prompts. Developers can add an MCP interface around existing capabilities without replacing their underlying application logic.

    Tool generates synthetic companies to test AI agents across business systems

    AIA tool can turn a one-line business description into a complete synthetic company spread across CRM, ticketing, Slack, files, emails, and call recordings. Developers can test agents against this connected data, then reset the company to its initial state and rerun the test when something breaks. The background post describes the product as Era, a free simulated enterprise that connects to Salesforce, Slack, Jira, Zendesk, Gong, and Deel through live MCP and API interfaces.

    Five-step Grok Bot method for hiring and managing AI agents

    AIBrian's Grok Bot method treats each bot like a new hire: define the role, test it on text first, run three trials, escalate based on evidence, and add a second agent only after a bottleneck appears. Each bot's role is defined by five fields: a real name with a short label, a one-line job tied to an outcome, what it owns, its inputs, and what it may do freely versus what it must ask before doing. The post frames an Agent Team as the final result of this process, starting with one coordinator and three specialists.

    Uber Designs an MCP Gateway to Expose Thousands of Internal APIs to AI Agents

    AIUber uses a control plane and data plane gateway to automatically convert its internal APIs into MCP tools, with 800+ MCP servers and 5,000+ tools hosted. The design includes an AutoCrawler that generates tool descriptions with an LLM, a default-disabled discover-not-expose security model, and techniques such as Omni MCP, Response Projection, and Code Mode to limit context bloat.

    Server-Side Code Execution Tools for AI Agents, Compared

    AIOpenRouter's shell and bash tools, along with those from OpenAI and Anthropic, run an agent's commands in provider-managed sandboxes during the same API request, so developers don't provision or patch containers. OpenRouter's tools are in beta, with sandbox time billed at $0.0001 per second and a 30-second minimum for a new or sleeping container. The article compares the four providers and notes that self-run sandboxes remain better for custom base images, GPU work, or multi-hour sessions.

    Microsoft ThinkingBox grades AI agents on database state across 20 repeated runs

    AIMicrosoft and Hugging Face released ThinkingBox, a benchmark that grades AI agents on the terminal backend state and side effects they leave behind rather than their final responses. Each of 507 stateful business tasks runs 20 times from a clean backend, and the post reports pass@1, pass@20, and observed 20/20 counts, plus cost per successful and per dependable task across 18 models. The harness and dataset are available on Hugging Face, with the OpenEnv interface for running evaluations.

    Why it matters: The post shows why checking the database state, not tool calls or final replies, exposes agent failures, and gives a repeat-run method for judging reliability.

    Claude Code v2.1.288 is released with fixes and new controls

    AIAnthropic released Claude Code v2.1.288, adding $.ui.selection() for mods, a built-in gh api for cloud sessions without the GitHub CLI, and --max-findings for /code-review. The release also fixes many issues, including mid-response API timeouts, resume and compaction bugs, and auto mode denials and model switching on Bedrock and Mantle.

    Omnigent: open-source meta-harness coordinating Claude Code and Codex agents

    AIDatabricks' new open-source meta-harness, Omnigent, lets multiple coding agents such as Claude Code and Codex share sessions, rules, and security policies in one system. A walkthrough by @leonvz demonstrates forking work across agents, multi-agent review and debate with Debby, and splitting implementation across subagents with Polly.

    How to Get Better at AI by Asking AI

    AIEvery's senior editor describes moving from single-thread chatbot prompting to delegating complex projects to teams of coordinating subagents, using skills, orchestrator threads, context packets, MCPs, and computer use. He says a subagent workflow verified employee equity costs across multiple grants, strike prices, and vesting schedules, and returned a draft Slack message for approval. The shift was prompted by a June tweet in which Codex placed a colleague at Level 5 of the "Eight Levels of AI Adoption" framework.

    Prime Inference launches serverless and reserved serving for open frontier models

    AIPrime Inference is a serving platform for frontier open-source models, offering serverless endpoints and reserved capacity on Prime's GPU infrastructure across multiple datacenters. Its first public deployment, GLM-5.3, went live on OpenRouter on September 22, and the post reports a near-zero tool-call error rate and 100% uptime since launch. The post also describes GLM-5.3 serving on GB200 NVL72 with prefill/decode disaggregation and NVFP4 KV compression.

    Why it matters: The post separates scheduler, KV-cache, and tool-call fixes, showing concretely which bottlenecks shape production serving of open frontier models.

    How agent frameworks handle tool-calling schemas across model providers

    AITool definitions and tool-call responses differ between OpenAI, Anthropic, and Google, so a tool that works on one model may fail on another. The article compares six agent frameworks, including LangChain, CrewAI, and the OpenAI Agents SDK, by where each performs schema translation. It also describes OpenRouter's API-layer normalization, which accepts an OpenAI-style tools array and returns a standard tool_calls response for tool-capable models.

    Claude Code adds mods that customize behavior and UI via TypeScript plugins

    AIClaude Code can now be modified with mods that change its behavior, customize the UI, and add features, written in a few lines of TypeScript or generated by Claude. Mods ship inside plugins and are installed with /plugin in the CLI or desktop app. A TypeScript function can intercept internal events such as tool calls, prompts, model requests, and renders, and add custom UI and commands.
