Show HN: OSS Pi Agent for Slack and Linear

A team has released Digby, an open-source AI agent for Slack and Linear that is self-modifying and self-improving, built on the pi framework. The agent deploys to AWS, uses Claude Sonnet on Bedrock, and can autonomously open PRs, ingest customer conversations, and ship features. It has become a core tool for the company's operations.

We've been using a now-discontinued version of pi-mom from the pi monorepo for a few months now. Digby is a slackbot which you can also assign Linear issues to. It has a private (Sign In with Slack, locked to your team) wiki and can serve raw assets. It's pi, so it's self-modifying and self-improving.

This isn't enterprise-grade, super secure stuff, but really a pi session anyone can use and one can works really well. Out of the box it deploys (and redeploys itself when PRs merge) itself to AWS on a small container. Runs on Claude Sonnet on Bedrock, but can use any Bedrock model easily. If you give it a Github token it'll open PRs to your codebase on its own behalf (or whoever owns the token -- very much advise you give it its own account). It can sign you into MCPs, and open its own browsers using Browser Use. Most importantly, it's very easy to fork and extend and make your own.

We've been slowly improving a lot of the sharp edges the original pi-mom came with, to the point it's usable enough for anyone to use out of the box reliably.

Some examples of use case: We gave it our Granola (MCP) and every day it ingests customer conversations and builds out our shared wiki and posts insights to a dedicated channel. It has Claude Code and Codex binaries inside to do Real Work, and does analysis and visualisations of these. Our commercial team ship features end-to-end (against preview PRs) and can work with customers iteratively and directly. It proactively investigates issues using the Datadog CLI. Much like OpenClaw you can just tell it to adjust it's behaviour and it does, and has turned into a kind of central command center guy for keeping in touch with releases and shipping Linear tickets (which scale as a nice substrate shared across dev machines, mobile-on-the-run, and shared chat).

No support but PRs welcome of course. Hope this is of use to anyone! We've loved it as an opportunity to test the limits of Sonnet and Pi and it's become a core part of our company Get Shit Done.
