For teams working with coding agents

Your engineers keep understanding the code their agents write.

After each task, the coding agent asks the engineer questions on the libraries and concepts it just used. VS Code asks the same questions, and a Slack post puts questions in front of the whole team every weekday.

Each engineer’s record is private to them by default. The team sees the standings and a Monday recap of what the questions covered.

A panel holds 4000px of content and closes with the rule below. What does the box you can see do during the 300ms?

.panel { max-height: 9999px; transition: max-height 300ms linear; }
.panel.is-closed { max-height: 0; }

01Where the questions come from

The agent asks first. VS Code and Slack follow.

01/03In the coding agent

After each task, questions on the topics the agent just worked on.

Claude Code, GitHub Copilot, Cursor, Codex or any MCP client. Each engineer runs one command in their repo, and the questions arrive in the same session when a task finishes.

02/03In VS Code

The same questions, in a panel beside the terminal.

The extension works in VS Code, Cursor and Windsurf. An engineer answers with a letter key and reads the explanation without leaving the editor.

03/03In Slack

A daily post the whole team answers.

Questions post in the channels you pick, on the topics you pick for each channel. Engineers answer with one click, and the explanation follows right away. Try the one in the window.

02What the Team plan turns on

Every squad answers its own stack.

One channel means one mix. Give each squad its own channel, tuned to the stack it works in. You set it once in the Hub.

03/04The recap

The Monday recap lists what last week was about.

A thread under last week’s last rep with the questions that came up.

Atomic RepsAPP9:00 AM

Monday recap · #squad-platform

Last week’s reps, one of them with the answer that looked right:

CPU throttling on a container with a 500m limit. Usage shows 200m on average. How is this possible?

Looked right: “A reporting lag in metrics-server.” The explanation: CFS meters each 100ms window, not the average.

Free on one channel. Team turns the six on.

It arrives where the work already is.

04The price

One channel is free. Team is priced by headcount.

Pick the size that fits your team: five sizes, starting at 10 engineers. Each step up costs less per engineer.

Per engineer, a year

$15610 engineers

$108250 engineers

One channel is free for everyone in it, no card. Team starts at the 10-engineer size, 30 days free to start.

Every size and the full sheet, on the pricing page

05Before you click Allow

Eight permissions. Slack’s wording on the left, and what each one means for your team on the right.

It cannot, and will not

Read messages in any channel or DM.
Open files, canvases or huddles.
Post anywhere you did not pick.
Message anyone who typed /reps mute.
Train AI on your answers, or sell or share them.

What it needs, and why

Channel names. So the picker has something to list.
Who is in the workspace. So an answer counts toward the person who typed it.
One email address at a time. When the installer claims the workspace, and the first time a member answers, so a Slack name becomes the right account.
Permission to post, and to DM. The daily rep in the channel you picked. DMs only if you move delivery there, or for the apprentice.

Information Atomic Reps can view

View basic information about public channels in your workspace

channels:read

Channel names and ids, so the picker has something to list. Never what is said in them.

View basic information about private channels that Atomic Reps has been added to

groups:read

The same list for private channels, and only the ones you invite the bot into.

View people in your workspace

users:read

So an answer counts toward the person who typed it and not a stranger.

View email addresses of people in your workspace

users:read.email

Slack grants this at install. We read nothing at install. We read one address at a time: when the installer claims the workspace, and the first time a member answers. We use the address to link a Slack name to the right account.

Actions Atomic Reps can take

Send messages as @atomicreps

chat:write

Post the daily rep, then edit it at the end of the day to close it.

Send messages to channels @atomicreps isn't a member of

chat:write.public

So you never have to /invite the bot before the rep can be posted in the channel you picked. The bot posts to the channels you choose and nowhere else.

Start direct messages with people

im:write

Direct messages, if you move delivery to DMs, plus the apprentice's updates. /reps mute ends them.

Add shortcuts and/or slash commands that people can use

commands

Registers /reps, the command for practice, stats and help.

Details in the Privacy Policy, Security and the Data Processing Agreement. Export or delete your own record from your account page. Cannot add apps to your workspace yourself? Send it to whoever can.

If you cannot install it yourself

If yours is one of the strict ones, send this to whoever can. It is written to be read by a person, not forwarded as a pitch deck.

The pitch, ready to pasteSlack DM

Hi, have you heard of Atomic Reps? They teach software engineers right inside Slack. It works like this: a short question shows up in the channel, you think for a moment, then the answer and the explanation show up right below. Pulling the answer from memory like that? It's called retrieval practice, one of the best-established ways to improve retention. Nothing to schedule, nothing to sit through, it barely feels like studying. But a small thing every day adds up fast. You're the one who can add apps here, so I'm sending it your way. Wanna take a look? https://atomicreps.com
