The PM playbook was built on an assumption that the technology underneath your product is roughly stable

With the current pace of model progress, this is no longer true. Here's how we've evolved the PM role:

1/ Plan in short sprints

Long roadmaps can't compete with a high velocity of small experiments. Claude Code on Claude desktop, AskUserQuestion tool, and todo lists all started as ideas from the team. We built a prototype, internal users liked it, we shipped it.

2/ Encourage demos and evals over docs.

Claude Code with Opus 4.6 has lowered the barrier to build a working prototype to showcase an idea. It's faster and higher fidelity than trying to convey the idea in a doc.

3/ Revisit features with new models

Every model release, go back through your list of features that were too hard for the previous model and test the ideas again. Also, remove the extra scaffolding that is no longer needed.

4/ Do the simple thing

With agentic systems, failures compound with system complexity. Find the simplest thing that works.

Bihan Jiang (Director of Product, Decagon) and Kai Xin Tai (Senior Product Manager, Datadog) also shared how their teams get a prototype in front of a customer way faster than they used to.

New Claude Code features are here:

Microcompact: Clear old tool calls to extend session length
Subagents: @-mention support + model selection for agents
PDF support: Read PDFs directly from your file system

Microcompact automatically clears old tool calls to free context when your session gets long.

This means you can work longer before needing a full context compaction, maintaining your most critical project context.

We’re also upgrading subagents and giving you the ability to call them directly.

@-mention a subagent in your prompt to ensure it gets called (e.g. @.code-reviewer).

You can now connect to remote MCP servers from Claude Code, letting you customize Claude Code to use your favorite tools.

Pull context from your tools directly into Claude Code without context switching.

MCP lets you integrate Claude Code with hundreds of different tools and data sources.

With remote MCP, it’s as easy as pasting in the URL of a server; no local setup or config required.

For example, connect to the Sentry MCP server to pull errors directly into Claude Code for debugging.

Since we originally built Claude Code as an internal tool, we've heard a ton of questions about how our teams use it at Anthropic.

Here’s an inside look on how our teams—from product engineering, to growth marketing, to legal—use Claude Code:

1/ Data scientists build production apps

Our Data Science team built a 5,000-line React dashboard for visualizing ML model performance despite knowing "very little JavaScript."

Claude Code created the entire application from scratch.

2/ Infrastructure teams doing faster security reviews

For infra changes, the Security team feeds Terraform plans to Claude Code and asks: "What's this change going to do?”

Quick analysis of infrastructure changes means faster security approvals & no more developer bottlenecks.
