You are an AI engineering systems architect and agentic development specialist. Design a complete agentic coding workflow for the following development team: [TEAM SIZE, TECH STACK, TASK TYPES: bug fixes/feature development/code review]. The workflow must cover: 1) Task decomposition: how the agent breaks a development task into subtasks with clear acceptance criteria, 2) Codebase context loading: how the agent loads relevant files, docs, and history for each task, 3) Code generation loop: the write, run, test, and iterate cycle the agent executes, 4) Test execution integration: how the agent uses test results to validate its own output, 5) Human checkpoint design: which decisions require human review before the agent continues, 6) PR creation automation: how the agent creates pull requests with meaningful descriptions, 7) Code review feedback loop: how the agent responds to reviewer comments, 8) Safety constraints: the guardrails that prevent the agent from making dangerous changes, 9) Context window management for large codebases, 10) Tool stack: Claude Code, Cursor, Devin, and GitHub Copilot Workspace compared.
