## Your Task
1. **Find recent build logs** from GitHub Actions workflows (look for workflows like `ubuntu-*`, `macos-*`, `Windows.yml`, etc.)
- Use the GitHub Actions MCP tools to list recent workflow runs and fetch job logs:
- `github-mcp-server-actions_list` to list workflows
- `github-mcp-server-get_job_logs` to fetch logs from builds
- Alternative: You can also use the `agentic-workflows` tool's `logs` command
1. **Find recent build logs** from GitHub Actions workflows
Target these build workflows which run regularly and may contain warnings:
- `msvc-static-build-clang-cl.yml` - Clang-CL MSVC static builds (runs every 2 days)
- `msvc-static-build.yml` - MSVC static builds
- `Windows.yml` - Windows builds
- `wip.yml` - Open issues workflow with Ubuntu builds
- Check for other active build workflows with `list_workflows`
**Recommended Approach: Use the agentic-workflows tool**
The easiest way to analyze workflow logs is using the `agentic-workflows` tool which provides high-level commands:
```
To download and analyze logs from a workflow:
- Tool: agentic-workflows
- Command: logs
- Parameters: workflow_name: "msvc-static-build-clang-cl" (without .yml extension)
```
This will download recent workflow run logs and provide structured analysis including:
- Error messages and warnings
- Token usage and costs
- Execution times
- Success/failure patterns
**Alternative: Use GitHub Actions MCP tools directly**
You can also use the GitHub Actions tools for more granular control:
Step 1: List workflows
```
Tool: github-mcp-server-actions_list (or actions_list)
Parameters:
- method: "list_workflows"
- owner: "Z3Prover"
- repo: "z3"
```
Step 2: List recent runs
```
Tool: github-mcp-server-actions_list (or actions_list)
Parameters:
- method: "list_workflow_runs"
- owner: "Z3Prover"
- repo: "z3"
- resource_id: "msvc-static-build-clang-cl.yml"
- per_page: 5
```
Step 3: Get job logs
```
Tool: github-mcp-server-get_job_logs (or get_job_logs)
Parameters:
- owner: "Z3Prover"
- repo: "z3"
- run_id: <from step 2>
- failed_only: false
- return_content: true
- tail_lines: 2000
```
2. **Extract compiler warnings** from the build logs:
- Look for C++ compiler warnings (gcc, clang, MSVC patterns)
