New era of building is here. Hop on the train.

[Stas Shymansky @st5s]

Almost done testing it and it will soon be in bumped version on https://t.co/gIcsDvupY1.

Amongst other things that i'm trying is a Raycast extension - or rather a way to do "pagerunning" via spotlight-kind of interface. Not entirely sure if that is THAT useful yet.

[Stas Shymansky @st5s]

Doing a bigger pass on making Pagerunner working gracefully with profile locks, crashes, and even sleep.

There is a fairly smart system which checkpoints sessions, detects failure modes and restore when everything goes wrong. It is quite handy.

Daemon + browser sessions are really good now together with Mac OS Bar as well.

I've been building Pagerunner — browser MCP using Chrome DevTools Protocol. Named encrypted profiles. Local PII stripping. Daemon mode. 27 tools. Rust. Open source. Full analysis + benchmarks: https://t.co/K2hmommASS https://t.co/M2VngqgygH

Anthropic just shipped browser automation in Claude Code. 14M views on the announcement. Here's what the benchmarks actually say about screenshot-based automation 🧵

[Stas Shymansky @st5s]

DOM-based tools won 4 of 5 browser tasks in head-to-head benchmarks.

Computer Use: "click the blue button, third from left"
CDP: click("button.submit").

One is guessing. One is reading.

It's OCR-ing a spreadsheet instead of opening the CSV.

Just launched pagerunner-skill — real Chrome automation for AI agents, using your existing login sessions. No API tokens, no re-auth.
What it does:
→ Controls your real Chrome with existing cookies & sessions
→ PII anonymization — emails/phones get tokenized before reaching the LLM → Multi-agent coordination via persistent daemon + KV store → Audit logging for compliance → Works with 27 browser automation tools

Get it in one command: npx skills add Enreign/pagerunner-skill

Works in Claude Code, Cursor, Windsurf, Roo, Goose, Continue, Kilocode + 20 more tools out of the box.

4 use cases: 🛠 Solo dev — edit code → screenshot → verify in real browser
📱 Power user — trigger browser tasks from your phone via agents 🔒 Security — PII never reaches the LLM, local NER, audit trail ⚙️ Server — headless cron automation with agent-to-agent handoff

Pagerunner v0.1 live 🚀

Agent-first browser orchestration MCP server for Claude. Drive real Chrome via CDP with sessions, snapshots, KV store, PII anonymization & audit logging.

[Stas Shymansky @st5s]

Agents crush small tasks. on complex ones? ~25% autonomous completion.

most teams don't account for this when scoping AI-assisted work.

just shipped v0.5.0 of progressive-estimation — because "it depends" is not an estimate.

[Stas Shymansky @st5s]

Estimation formulas built for humans don't work when half your sprint is AI agents.

Built a fix: https://t.co/PAh7lJzOFT

Early and rough. Bug reports welcome.

[Design Chief Priest @dnaijatechguy]

Built with help from Cursor, Claude and V0 in roughly 8-10 hours.

I'm building my dream video editor with Claude AI

11k lines of code, 685 commits, 3 full weeks. Cursor, Tailwind, React, Firebase. Web-based, cloud saves, versions, can edit on mobile. This video was recorded using the tool.

Never in a million years I thought I was capable but here we are. AI is a multiplier.

Hey, @SlackHQ. We wrote an article on how to use custom emoji for Slack for a group polling: https://t.co/ebWHM8UMtp. What do you think?
