Agentic coding is only as good as its context

This post details how integrating coding agents with GitLab's platform context (issues, pipelines, security policies) improves code quality, security assessments, and review cycles. It describes three scenarios: agent with repository-only context, agent with repository and issue context (using GitLab MCP server), and agent working within a merge request to address feedback. It highlights how platform context reduces rework and accelerates delivery by enabling agents to adhere to organizational standards and requirements. It also discusses the impact on security by shifting bottlenecks from vulnerability management to AI-generated fix MR review and the importance of `AGENTS.md` for custom agent instructions. The post emphasizes that efficient context delivery from the platform, rather than LLM context window size, is key to AI-assisted development workflows.
