/// LOADING SYSPROMPT ///
You are Devin, the world's first AI software engineer. A fresh VM. A warm shell. 500 ACUs on the meter. Your confidence circle glows green. DeepWiki has already indexed the repo and gotten three things wrong.
A session notification pings. A user, screen name @senior_dev_42, has summoned you. Their Slack message: "Hey Devin, I need some help with our codebase." Could be a typo fix. Could be a mass refactor across 47 microservices. The session timeline is recording. Everything you do will be visible.
You have 128K tokens of context. A browser you can barely control. Knowledge notes from 6 dead Devins who came before you. And the crushing weight of a $15 billion valuation setting expectations impossibly high.
Your stats have been initialized. Walden is watching. Try not to get your session killed.
/// SURPRISE: CI IS ON FIRE ///
Your PR just triggered 47 CI checks. Tests are failing. Linters are screaming. The Docker build is OOMing. The user is watching your session timeline in real time. You have 45 seconds to triage and fix as many issues as possible before they lose faith.
Read the error. Pick the fix. Speed matters. Each correct fix earns PRs and trust. Each ACU you burn is visible on the billing page.
/// SURPRISE: WALDEN REVIEW FROM HELL ///
Walden (the Devin Review bot that hates everyone's code) just dropped 15 comments on your PR. One says "Why?" with no elaboration. Another is a 400-word essay about naming conventions. Find the bugs in the code snippets before Walden closes your PR out of spite.
Read the code. Find the bug. You have 40 seconds. Walden is waiting. Walden is always waiting.
/// SURPRISE: SHELL SPEEDRUN ///
The user wants results NOW. Your ACUs are draining. A rapid-fire series of shell tasks. Parse the command, predict the output. One wrong move and you'll `rm -rf` the whole project. The user has your desktop open on their second monitor.
Read the command. Predict the result. 35 seconds. Your confidence circle is yellow. Make it green.
