What You Will Do

• Ship with agents.Claude Code first, plus Codex, Cursor, Copilot or whatever earns its place - your main tool across planning, implementation, testing, debugging, refactoring, documentation and review. Real features in production, with the quality bar you would hold for hand-written code.
• Own the output.Treat what the agent writes as untrusted until you have reviewed it: hallucinations, wrong assumptions, hardcoded secrets, missing validation, injection-prone patterns. Run it, confirm it works, iterate. For authentication, authorization, cryptography and session handling, use our standard implementation rather than the model's invention.
• Fix the context, not the prompt.Keep CLAUDE.md, coding standards, architecture notes and module dependencies current so the agent gets it right the first time. Feed SAST (Static Application Security Testing) and dependency findings back with call path and data flow, so it writes a real patch instead of a suppression.
• Build team-level tooling.Prompts, skills, sub-agents and MCP (Model Context Protocol) integrations for the work that keeps coming back, plus guardrails that keep agents in bounds: architectural limits, forbidden patterns, off-limits folders. Keep the context lean and watch token cost.
• Use agents across the whole lifecycle, not just for code.Integration tests and coverage gap analysis, regression tests generated from real production incidents, root-cause analysis with logs and traces pulled in, ADRs (Architecture Decision Record) and runbooks drafted with AI and checked by you.
• Review AI-assisted work well.Run context-aware AI review on your own diffs, separate true positives from false positives, and turn recurring false positives or escaped bugs into rules the team keeps.
• Share what works.Show your setup to the team, review other people's AI-assisted pull requests, and get at least one thing you built adopted beyond your own repo.
