### [Hollywood demos vs. real](https://yomu.fyi/post/hollywood-demos-vs-real.md)
- Company: [Intercom](https://yomu.fyi/company/intercom.md)

AI demonstrations fall into two categories: polished “Hollywood demos” and raw “real-world demos,” with the latter showing how customer-service AI agents perform under messy, complex interactions rather than edited presentation. Voice provides an especially demanding test because timing, tone, turn-taking, latency, interruptions, and real-time adaptation all shape the experience. At Pioneer, Paul Adams called Fin Voice live; within 90 seconds, it verified identity, retrieved account data, handled an interruption, offered options, completed the workflow, and sent a follow-up email. The demonstration exposed brief pauses for backend work, natural conversational flow, tone changes, and unscripted behavior, while later updates added voice customization, escalation guidance, deployment controls, integrations, support for 28 languages, and roughly 30–40% lower latency since launch.


### [Improving agent with semantic search](https://yomu.fyi/post/improving-agent-with-semantic-search.md)
- Company: [Cursor](https://yomu.fyi/company/cursor.md)
- Author: Stefan Heule, Emily Jia & Naman Jain
- Published: Nov 6, 2025
- Type: Benchmark

Cursor describes semantic search as a complement to grep for helping coding agents locate relevant code in large codebases. Its evaluation used Cursor Context Bench across widely used models, comparing tool sets with and without semantic search, and found an average 12.5% accuracy improvement, with gains ranging from 6.5% to 23.5%. In an online A/B test, semantic search increased code retention by 0.3% overall and 2.6% on codebases with at least 1,000 files, while its absence produced a 2.2% increase in dissatisfied follow-up requests. The retrieval system uses a custom embedding model trained from agent session traces, with an LLM ranking helpful content and training aligning embedding similarity scores to those rankings. The conclusion is that combining semantic search with grep produces the best outcomes, especially for large codebases.


### [You Should Write An Agent](https://yomu.fyi/post/you-should-write-an-agent.md)
- Company: [Fly.io](https://yomu.fyi/company/fly-io.md)
- Published: Nov 6, 2025
- Type: Tutorial

Thomas Ptacek argues that people should build an LLM agent before forming strong opinions about the technology, because implementation reveals how simple and surprising the underlying system can be. The example starts with a Python loop around the OpenAI Responses API, storing user and assistant messages in a context list to simulate conversation with a stateless model. Adding a JSON-defined ping function and a tool-calling loop lets the model choose and execute multiple network checks, demonstrating behavior not explicitly hard-coded in the loop. The discussion extends this pattern to coding agents, contexts persisted in SQLite, sub-agents, and design choices involving nondeterminism, ground truth, interchange formats, and token costs. It concludes that these remain open software-engineering problems whose practical behavior can be understood by building and iterating on agents.


### [Introducing Cursor for Enterprise](https://yomu.fyi/post/introducing-cursor-for-enterprise.md)
- Company: [Cursor](https://yomu.fyi/company/cursor.md)
- Author: Cursor
- Published: Oct 31, 2025
- Type: Announcement

Cursor is introducing enterprise features intended to make its coding agents more capable, transparent, and secure for organizations already using the product. Hooks expose the agent loop to custom scripts that can log actions and tool calls, enforce compliance or command allowlists, scrub sensitive material, connect external systems, and trigger automations; they can be distributed through MDM or Cursor’s cloud option. Team Rules provide shared context and can recommend or require standards such as API schemas, conventions, and workflows, while upgraded analytics report activity, adoption, AI lines of code, directory-group filters, and exportable data with updates every two minutes. The release also adds an Audit Log covering 19 event types and Sandbox Mode, which restricts network and file access by default, with administrators controlling availability and team-wide Git and network access.


### [How to build a Content Design Agent](https://yomu.fyi/post/how-to-build-a-content-design-agent.md)
- Company: [Intercom](https://yomu.fyi/company/intercom.md)
- Author: Russell Norris
- Published: Oct 31, 2025
- Type: Tutorial

An overloaded solo content designer built VERBI, an AI content design agent, to scale standardized work without replacing human judgment or filling products with generic copy. The agent runs in Glean, using a curated collection of Intercom’s style guide, tone of voice, product and monetization glossaries, messaging guides, research, and official websites as retrieval-augmented generation sources. The system prompt defines its role, use cases, tone, and component rules, while a Glean Indexing API connection makes Storybook’s Surge design-system guidance available as a live source. Additional instructions tell VERBI to challenge users, avoid guessing when sources lack an answer, and keep responses concise. After 700+ triggers, the reported benefits are consistent content rules, faster drafts and iteration, fewer repetitive questions and errors, and more time for higher-impact design review.

At Pioneer 2025, Eoghan McCabe presented a plan for Fin to become a unified Customer Agent spanning the entire customer experience, from first contact through purchase, support, success, and upsell. The proposal responds to the risk that separate AI Agents for sales, marketing, success, and service will use conflicting priorities, disconnected information, and inconsistent interactions. Fin is intended to evolve from a task-based system into an agentic system with fluid roles, user-defined goals, persistent customer memory, comprehensive business knowledge, and interoperability across tools, systems, and channels. The post argues that customer service leaders are positioned to guide this wider AI rollout because they have experience, data, and operational insight from early AI adoption. Early activity includes WHOOP using Fin for sales conversations, where it is resolving 84%, while new capabilities are expected to roll out over the coming months.


### [Cloud Agents](https://yomu.fyi/post/cloud-agents.md)

- Type: Announcement

Cursor’s Cloud Agents let developers run multiple agents remotely without keeping a laptop connected to the internet. Agents can be launched and managed from the Cursor editor, cursor.com/agents, Slack, Linear, and GitHub, supporting background bug fixes, small todos, and larger feature work. For difficult bugs, the team commonly has multiple models attempt the same problem and selects the best result; for complex features, a locally developed plan can be sent to a cloud agent for implementation, allowing work to continue on another task. Cursor also revamped its GPT-5 Codex agent harness for longer time horizons in the cloud, while plan mode supports sending implementation plans remotely. The workflow is available today in Cursor editor and Cursor Web, as well as the listed integrations.

- Type: Announcement

Composer is a mixture-of-experts agent model for software engineering that targets interactive use, with reported frontier coding results and generation speed four times faster than similar models on the authors’ benchmarks. It is trained with reinforcement learning on real-world software engineering challenges in large codebases, using production search and editing tools, terminal commands, and codebase-wide semantic search. Training responses may be code edits, plans, or informative answers, while the process rewards efficient tool use, parallelism, minimal unnecessary responses, and evidence-based claims. Evaluation uses Cursor Bench, built from real agent requests and curated optimal solutions, measuring correctness alongside adherence to existing abstractions and software engineering practices. The training stack combines asynchronous reinforcement learning with PyTorch and Ray, MXFP8 MoE kernels, expert parallelism, hybrid sharded data parallelism, and sandboxed cloud environments scaled to hundreds of thousands concurrently.


### [Introducing Cursor 2.0 and Composer](https://yomu.fyi/post/introducing-cursor-2-0-and-composer.md)
- Company: [Cursor](https://yomu.fyi/company/cursor.md)
- Author: Cursor
- Published: Oct 29, 2025
- Type: Announcement

Cursor 2.0 introduces Composer, described as the product’s first coding model, alongside an interface designed for running multiple agents in parallel. Composer is built for low-latency agentic coding, completes most turns in under 30 seconds, and was trained with tools including codebase-wide semantic search to improve work in large codebases. The new interface centers on agents and outcomes rather than files, while still allowing users to open files in a redesigned layout or return to the classic IDE; parallel runs are isolated through git worktrees or remote machines. The release also targets review and testing bottlenecks by simplifying change inspection and adding a native browser tool that lets Cursor test its work and iterate, and Cursor 2.0 is now available.


### [Introducing Agent Skills](https://yomu.fyi/post/introducing-agent-skills.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Oct 16, 2025
- Type: Announcement

Agent Skills are folders containing instructions, scripts, and resources that Claude loads when relevant to specialized tasks, enabling custom expertise across Claude apps, Claude Code, and the API. The system scans available skills, loads only the minimal information and files needed, and can combine multiple skills automatically. Skills may include executable code, and API use requires the Code Execution Tool beta; developers can manage versions through the /v1/skills endpoint and Claude Console. Users can build skills with the skill-creator workflow or install them through the anthropics/skills marketplace, while organization-wide management and a partner-built directory were added in the December 18, 2025 update. The post presents Skills as composable, portable, efficient, and powerful, but cautions that code-executing skills should come from trusted sources to protect data.

Notion 3.0 introduces Notion AI Agents that can create documents, build databases, search across tools, and execute multi-step workflows inside a workspace. Agents can perform up to 20 minutes of autonomous work across hundreds of pages, including researching information, synthesising findings, creating structured databases, and notifying users when tasks finish. Users can personalise an Agent through a Notion page containing instructions and context, including task triage, response formatting, and reference information; templates can add specialised skills. The launch also includes database row permissions, new AI connectors, and additional MCP integrations, while Custom Agents are planned to run on schedules or triggers and share workflows with teams.


### [Usage Policy update](https://yomu.fyi/post/usage-policy-update.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Sep 15, 2025
- Type: Announcement

Anthropic is updating its Usage Policy to reflect product changes, user feedback, regulatory developments, evolving AI risks, and enforcement priorities, with changes taking effect September 15, 2025. The update adds explicit prohibitions on malicious computer, network, and infrastructure compromise while continuing to permit vulnerability discovery with system-owner consent, and provides supplementary guidance for agentic use. It narrows political restrictions from broad bans on lobbying and campaign content to prohibitions on deceptive or disruptive democratic activity and voter or campaign targeting. Law-enforcement wording is clarified without changing the permitted scope, while high-risk requirements are specified for consumer-facing legal, financial, and employment uses, including human oversight and AI disclosure. Anthropic describes the policy as a living document and says it will continue evaluation with policymakers, experts, and civil society.


### [Build Secure Agent-to-App Connections with Cross App Access (XAA) Using OIDC](https://yomu.fyi/post/build-secure-agent-to-app-connections-with-cross-app-access-xaa-using.md)
- Company: [Okta](https://yomu.fyi/company/okta.md)
- Author: Sohail Pathan
- Published: Sep 3, 2025
- Type: Tutorial

The guide presents Cross App Access (XAA) as a protocol for secure agent-to-app and app-to-app access, giving enterprise IT centralized control over connections, policies, and accessed resources. It walks through an OIDC demonstration using Todo0 as the Resource App, Agent0 as the Requesting App, and Okta as the enterprise identity provider, covering app registration, trust establishment, token exchange, and API calls. The flow uses the OAuth 2.0 Identity Assertion Authorization Grant: Bob logs in once, Agent0 obtains an identity assertion, Okta exchanges it for a Todo0 access token, and Agent0 calls the protected API. The demonstrated result is an agent that can read pending tasks, add tasks, and mark tasks complete, with changes reflected in Todo0. The guide is marked out of date because its Admin Console instructions have been replaced by AI agent registration under Directory > AI Agents.


### [Build Better Agents With MorphLLM](https://yomu.fyi/post/build-better-agents-with-morphllm.md)
- Company: [Fly.io](https://yomu.fyi/company/fly-io.md)
- Published: Aug 25, 2025
- Type: Problem & solution

The post addresses a bottleneck in AI agents that write or edit code: correcting a small change can trigger a full-file rewrite, consuming tokens and causing formatting failures, silent omissions, and unreliable results. MorphLLM’s Morph Fast Apply is presented as a semantic, structure-aware edit merge tool: an agent emits small edit\_file snippets with //...existing code... placeholders, while the Apply API merges them against the codebase context before the edited file is written back. The post reports over 4,500 tokens per second, 98% accuracy in about six seconds per file, and about four seconds for files up to 9k tokens, compared with 35 seconds and 86% accuracy for traditional search-and-replace with error corrections. It also states that MorphLLM is API-compatible with OpenAI, Vercel AI SDK, MCP, and OpenRouter, and can run in the cloud, self-hosted, or on-premises.


### [Automation, Squared](https://yomu.fyi/post/automation-squared.md)
- Company: [Ramp](https://yomu.fyi/company/ramp.md)
- Author: Hunter Pruett
- Published: Aug 12, 2025

The article presents “second-order automation,” in which one agent designs reusable workflows for another agent to execute. Its spreadsheet system pairs an “architect” that watches a screen recording, generates detailed prompts, identifies required files and context, with a “doer” that searches workbooks and performs the instructions. The design addresses first-order automation’s dependence on users to supply precise prompts and fresh context for every task, which limits scalability. On an approximately 50-task SpreadsheetBench subset, the spreadsheet agent reached 49.5% accuracy on soft-restriction tasks versus OpenAI’s 45.5%, and 32.5% on hard-restriction tasks versus GPT-4o’s 13.4%; some one-to-two-hour tasks finished in under 10 minutes. The article concludes that recorded workflows can let non-technical users create reusable automations with little additional input, although architect performance has not yet been formally benchmarked.


### [Announcing The AI Agent Blueprint](https://yomu.fyi/post/announcing-the-ai-agent-blueprint.md)
- Company: [Intercom](https://yomu.fyi/company/intercom.md)
- Author: Declan Ivory
- Published: Aug 12, 2025
- Type: Announcement

The AI Agent Blueprint is a strategic guide for support, customer experience, and AI transformation leaders navigating how to adopt and scale AI Agents. Its first part, “Launch it,” covers building a business case, deciding whether to buy or build, evaluating an agent with a four-step framework, planning deployment, and continuously training, testing, deploying, and optimizing performance. The second part, “Scale it,” focuses on redesigning customer experience, organizational and system design, and economics through AI-first journeys, new roles and governance structures, and revised metrics, ROI models, and reinvestment strategies. The Blueprint argues that launching an agent is only the beginning: sustainable value requires treating AI as infrastructure and support as a potential growth lever, and it is live now.
