### AI overview

Glyph is a production system for generating column descriptions and assigning sensitivity-ontology labels in enterprise data catalogs. It uses cooperating LLM agents, source-code-grounded retrieval, parallel tagging strategies, vector-based metadata matching, and ranked-output fusion to support auditable cataloging.

### Source excerpt

Enterprise data lakes accumulate tables faster than human stewards can document or classify them, leaving columns with missing descriptions and unassigned governance labels. This documentation debt undermines data discovery, access control, and regulatory compliance. We present Glyph, a production system that frames two coupled problems, column description generation and column type annotation for data classification, as cooperating LLM agents orchestrated as stateful graphs. The Descriptor grounds generation in the pipeline source code that produces each column, retrieved on demand from an...

### AI overview

Pulumi is launching the Context API, a read-only API that connects Pulumi-managed and discovered resources, stacks, and their relationships into a graph. Available in public preview for Enterprise and Business Critical organizations, it supports infrastructure-impact, coverage, and cleanup queries through the Pulumi CLI or REST API. Pulumi Neo uses it out of the box, and other authenticated agents can access its schema and query guidance.

### Source excerpt

Every platform team fields the same questions: What is running? What breaks if we change this? What can we safely delete? The answers exist, but they're scattered across state files, cloud consoles, and the memories of whoever set things up. Today we're launching the Pulumi Context API, a read-only API that connects Pulumi-managed and discovered resources, stacks, and their relationships into a graph. It's designed agent-first: Pulumi Neo, our infrastructure agent, uses it out of the box, and other agents can fetch the current graph vocabulary and query guidance on demand. It's available in public preview for organizations on the Enterprise and Business Critical editions. Answers that follow infrastructure relationships Pulumi already records the resources your programs manage, their dependencies, how stacks consume each other's outputs, and the resources Pulumi Discovery finds outside infrastructure as code (IaC). The Context API connects this data so you can ask questions that depend on the relationships: Impact: Which stacks are affected if we upgrade this provider? If this stack changes, what consumes its outputs? Coverage: How much of our infrastructure lives outside IaC, and in which accounts? Cleanup: Which stacks have no dependents and are candidates for retirement? A query is a JSON document with a handful of clauses. anchor names the starting nodes, traverse follows relationships from there, and return chooses what comes back. You can run a query through the Pulumi CLI or REST API. Here's a selector that starts from AWS provider instances older than version 7.0.0 and follows incoming provided_by relationships back to the visible resources they manage: { "anchor": { "nodeType": "resource", "match": { "type": "pulumi:providers:aws", "fields": { "provider_version": { "op": "lt", "value": "7.0.0" } } } }, "traverse": [ { "edgeTypes": ["provided_by"], "direction": "in", "alias": "managed" } ], "return": { "select": ["anchor", "managed"] } } A response for one m

### AI overview

The article argues that AI coding agents struggle in real codebases primarily because they lack access to a knowledge graph connecting code, APIs, services, ownership, dependencies, policies, and related organizational context. It describes service catalogs, API registries, ownership maps, dependency graphs, and internal developer platforms as different forms of the same underlying structure. It also argues that simply increasing the context window does not solve retrieval and context-quality problems.

### Source excerpt

AI coding agents don't fail from small context windows. They fail without a knowledge graph of your code, APIs, and vendors. The post Why AI coding agents need context graphs appeared first on Postman Blog.

### AI overview

This opinion argues that AI agents and large language models are making code production cheaper and faster, shifting the main challenge for enterprise software development toward context, verification, governance, identity, policy, approval, and audit. It discusses how the software development lifecycle and its underlying architecture must adapt to machine-scale concurrency and automated workflows.

### Source excerpt

I returned from the holiday break in January convinced that something fundamental had changed. Large language models had reached the point where they could produce useful code reliably enough, and cheaply enough, to change the economics of software development. Engineers everywhere seemed to be experimenting with the same thing: not just asking an AI assistant for suggestions, but giving agents real work and seeing how far they could take it. I started thinking about what happens if that continues. What changes when producing code is no longer the primary constraint in building software? I wrote those thoughts down in a board memo in January. In May, I published part of that thesis in GitLab's Act 2: the cost and time of producing software was collapsing, machines would increasingly build software under human direction, and the architecture underneath software development would have to change with it. In June, at GitLab Transcend, we showed the first pieces of that architecture: source control rebuilt for machine-scale concurrency, GitLab Orbit as a context graph spanning the software lifecycle, and governance around agent identity, policy, approval and audit. Then, on August 21, Anthropic published The AI-Native SDLC Playbook. It opens with a simple statement: "Code is no longer the bottleneck." I agree. Anthropic's playbook is a practical description of how the development lifecycle changes when agents can move implementation dramatically faster: planning becomes machine-readable, handoffs become automated, verification moves into the loop, and human judgment concentrates at the gates. What interests me is what happens one level beyond the workflow. If code is no longer the primary constraint, what becomes scarce? What architecture does an enterprise need when people, agents and multiple models are all acting across the software lifecycle at machine speed? And where does durable value move when generating the code itself becomes increasingly abundant? Over the pas

### AI overview

The article distinguishes two generations of agentic engineering. Version 1.0 uses AI agents in deterministic workflows with predefined stages, prompts, responsibilities, and hand-offs. Version 2.0 gives an agent a goal and lets it determine the path, with the foundation built during the first generation enabling that transition. A self-healing incident workflow illustrates the contrast.

### AI overview

Netflix's third-part blog post describes the serving layer for its Real-Time Distributed Graph and explains how gRPC enables efficient graph querying. It focuses on serving diverse workloads, including security lookups and personalization traces, with sub-100ms responses across a billion-edge graph.

### Source excerpt

How and Why Netflix Built a Real-Time Distributed Graph: Part 3 -- Querying the graph with gRPC execution API Authors: Nilesh Mishra and Ajit Koti This is the third entry of a multi-part blog series describing how we built a Real-Time Distributed Graph (RDG). In Part 1, we discussed the motivation for creating the RDG and the architecture of the data processing pipeline that populates it. In Part 2, we discussed how we designed the storage layer to handle billions of nodes and edges while maintaining single-digit-millisecond latency. In Part 3, we will explore how we designed a fast, flexible serving layer to efficiently query the graph. Introduction In Part 1 of this series, we described why Netflix needed a Real-Time Distributed Graph (RDG) and how we used Apache Flink to build an ingestion and processing pipeline that turns streaming events into graph primitives. In Part 2, we explored how we designed a storage layer capable of handling billions of nodes and edges while still delivering single-digit-millisecond latency. In this post, we focus on the next challenge: querying the graph efficiently to power real-time insights for our internal partners. All of the work on ingestion and storage only matters if we can actually ask complex questions and get answers back quickly. As we optimized for lower latency, we found that the serving layer posed its own set of challenges, distinct from those of ingestion and storage. How do we turn a constantly evolving, billion-edge graph into sub-100ms responses across a wide variety of workloads? This is the problem we tackle in this post. The Real World Needs As we integrated the RDG into Netflix's ecosystem, we realized that "querying the graph" is not a one-size-fits-all operation. We needed to handle a wide range of access patterns: from high-volume security lookups to deep, exploratory personalization traces. Let's revisit our example from Part 1 and expand on it slightly. In the earlier posts, we focused on accounts, device
