The report writer is capped at 3. A 60-second rate-limit pause fires between every agent step to stay within API RPM limits.\n\n## Agents\n\n| Agent | Tools | Looks For |\n|---|---|---|\n| Bug & Logic Reviewer | GitHub Search | Bugs, edge cases, unhandled exceptions, race conditions |\n| Security Reviewer | Web Search | OWASP top 10, CVEs, injection, hardcoded secrets, insecure APIs |\n| Style Reviewer | Web Search | PEP 8, naming, readability, Pythonic patterns |\n| Report Writer | None | Synthesizes all findings into a final structured report |\n\n## Output\n\nEach run produces a markdown file named `review_pr_<number>.md` containing:\n- Bug & logic findings with severity ratings\n- Security vulnerabilities with severity ratings\n- Style and best practice suggestions\n- Overall code quality assessment\n\n## Setup\n\n**Requirements:** Python 3.10–3.13, [Poetry](https://python-poetry.org/)\n\n```bash\ngit clone https://github.com/<your-username>/MultiAgentOrchestration_CodeReview.git\ncd MultiAgentOrchestration_CodeReview\npoetry install\n```\n\nCreate a `.env` file in the project root:\n\n```env\nGITHUB_TOKEN=your_github_personal_access_token\nSERPER_API_KEY=your_serper_api_key\nGEMINI_API_KEY=your_gemini_api_key\n```\n\n- **GITHUB_TOKEN** — needed to fetch PR diffs and for the GitHub Search tool. Generate at [github.com/settings/tokens](https://github.com/settings/tokens) with `repo` scope.\n- **SERPER_API_KEY** — powers web search for the security and style reviewers. Get one at [serper.dev](https://serper.dev).\n- **GEMINI_API_KEY** — the LLM backbone (Gemini 2.5 Flash). Get one at [aistudio.google.com](https://aistudio.google.com).\n\n## Usage\n\n```bash\npoetry run python main.py\n```\n\nWhen prompted, paste any GitHub PR URL in any of these formats:\n\n```\nhttps://github.com/owner/repo/pull/123\nhttps://github.com/owner/repo/pull/123/files\nhttps://github.com/owner/repo/pull/123/changes\nhttps://github.com/owner/repo/pull/123#diff-abc123\n```\n\nThe pipeline handles trailing path segments and hash fragments automatically.\n\n## Project Structure\n\n```\n├── main.py            # Entry point — orchestrates the crew\n├── agents.py          # Agent definitions (role, tools, limits)\n├── tasks.py           # Task definitions (prompts, expected outputs)\n├── models.py          # Pydantic output schemas for structured results\n├── github_fetcher.py  # PR URL parser + GitHub API diff fetcher\n├── llm.py             # LLM configuration (Gemini via CrewAI)\n└── pyproject.toml     # Dependencies (Poetry)\n```\n\n## Dependencies\n\nManaged via Poetry.
