Coding agents in real codebases: Claude Code, Cursor and Copilot, sandboxed execution, guardrails for generated code, and AI-assisted testing and review.
Hitting Claude Code’s weekly limit by Wednesday? /usage now shows where the allowance goes. Subagents running on your main model, long sessions and idle loops are the usual suspects, and most fixes are a setting.
Green CI only proves the branch builds and passes the tests it ships with. Read the task, the file list and the test diff before the implementation, and run the new tests against the old code.
Docker Sandboxes run coding agents in their own microVM. What that isolates compared with a container, and how to set up clone mode, proxy-injected credentials, deny-by-default network rules, kits, templates and shared skills so the isolation still holds.
A single green CI run tells you a change can pass, not that it does pass. Three gates that hold up when part of the diff was written by an agent: assert on observable state, repeat the run N times, and enforce a flake budget you define yourself.
Public leaderboards measure someone else’s repo. Here’s how to build a 20-task eval from your own git history, grade it with deterministic pass/fail scripts in a sandbox, and put the winner behind a router so the next switch is a config change.
