Ramping into unfamiliar systems
Tell someone how to act on this idea: "The job is to integrate protections into systems the team has often never dealt with before."

Ramping into unfamiliar systemssecurity's defining horizontal-coverage challenge
Security is unusually horizontal. The job is to integrate protections into systems the team has often never dealt with before. That used to mean a week of reading code and docs before you could move the needle on a new service. Models are good at exactly this part - ramping you in and teaching you about something, with no dumb questions to be embarrassed about.
A new system used to mean: I'd have to spend a week to learn about that thing. Now you can ramp up and learn so quickly that you go straight to moving the needle and locking it down. The bottleneck moves from understanding the system to deciding what to harden.
The concrete demo for this is repo reconnaissance. Point an agent at an unfamiliar GitHub repo and ask for the digest you'd otherwise assemble by hand. One recorded research session ran about 6.5 minutes of agent work and saved an estimated half hour at one checkpoint, closer to an hour once you count the docs you'd have read.

Repo Recon: Ramping into an Unknown Codebase
Interactive diagram. Step through it with the Next and Previous controls below, or Tab to a region to read its detail.
Point the agent at a repo and ask for one digest. Each step is a question you'd otherwise chase across files, commits and docs by hand.
If asked how you'd onboard to Cursor's unfamiliar codebases fast, don't say "I'd read the docs." Describe the agent-assisted ramp: point an agent at the repo, pull a digest of age, owners, purpose, hygiene and architecture, then spend your human time deciding what to harden rather than reconstructing what the system is. That answer signals you already work the way the team does.
