the MCP session started, 30 min later Claude Code SDK session started and there was a mass migration over to Claude SDK

it’s the future..

Anthropic speaker

how to build agents (according to Anthropic)

A conference room filled with attendees facing a large projector screen. The slide on the screen reads:

“The Agent SDK is the best way to build agents in the ‘Anthropic Way’
• Unix Primitives: Every agent should use bash [1] & a file system [2] (e.g. skills & memory)
• Agents > Workflows: Agents build their own context + decide what to do with tools.
• Code Generation for non-coding: We use code gen to generate docs, query the web, etc.
• Every agent has a container.

More on this here.”

A presenter stands on the right side of the room holding a microphone, speaking to the audience. People in the audience sit closely together, many with laptops open. The lighting is bright and even, and the room has a modern ceiling with recessed fixtures.

Anthropic is giving away all their secrets

A conference room with many attendees seated and facing a large projected slide. The slide reads:

“Bash is all you Need

Bash is what makes Claude Code so good.

Bash is a generic version for ‘code mode’ or programmatic tool calling.

The bash tool allows you to:
– Store the results of tool calls to files, so you can search them.
– Store memory in files.
– Dynamically generate scripts and call them.
– Compose functionality, use unix primitives like tail, grep, cat, etc.
– Use existing powerful software like ffmpeg, libreoffice, etc.”

A small label in the upper-right of the slide says “Tharig Shihpur.” The presenter stands on the right side of the image holding a microphone, wearing a light sweater and conference badge. Attendees in the foreground sit closely together, some working on laptops. The lighting is bright and the ceiling has circular fixtures.

ant man is talking as if he’s not 100% sure if bash counts as codegen

if you can make validations, you’re going to have a very good agent. Sometimes it’s very hard, like deep research

A projected slide titled “Claude Agent SDK Loop” showing a simple three-step flow diagram. From left to right, three rounded rectangles read:
• Gather context (in light blue)
• Take action (in bright green)
• Verify work (in yellow)

Arrows connect the boxes in sequence, and two return arrows loop back from “Verify work” to “Gather context.” In the upper-right of the slide is a small label reading “Tharig Shihpur.” At the bottom right corner, faint text reads “CONFIDENTIAL.”

In the foreground, attendees sit facing the screen. On the right, a presenter stands holding a microphone, wearing a light sweater and conference badge. The room has a modern ceiling with circular vents and even lighting.

codegen v bash v tools

—ant man

A projected slide titled “Tools vs Bash vs Code Generation” with three sections comparing pros and cons. The text reads:

Tools:
• Pros: Highly structured, highly reliable
• Cons: High context usage, not composable

Bash:
• Pros: Composable, static scripts, low context usage
• Cons: Longer discovery time, slightly lower call rate

Code Gen:
• Pros: Highly composable, dynamic scripts
• Cons: Needs linting & possibly compilation, careful API design

In the upper-right corner of the slide is a small label reading “Tharig Shihpur.” At the bottom right, faint text reads CONFIDENTIAL with a slide number “30.”

The audience is seated in the foreground, with many people facing the screen. The presenter stands on the right side holding a microphone, wearing a light-colored sweater and a conference badge. The room has a modern ceiling with circular vents and bright, even lighting.

sorry y’all, i fucked up and scheduled brunch with the inlaws, that’s the end of today’s AIE coverage
