### Step 1: Download and Extract the Artifact ### Step 1: Download and Extract the Artifact
**Important:** Use the **GitHub MCP server tools** (actions toolset) to interact with GitHub, not bash/curl commands. Use the GitHub MCP server tools (actions toolset) — not bash/curl. For `owner` and `repo` parameters, extract them from `${{ github.repository }}` (format: `owner/repo`).
1. **Find the most recent workflow run** of `a3-rust.yml`: 1. Call `list_workflow_runs` with `resource_id: a3-rust.yml`. Take the run ID from the first (most recent) result.
- Use the `list_workflow_runs` tool with: 2. Call `list_workflow_run_artifacts` with `resource_id:` set to that run ID. Find the artifact named `a3-rust-output`.
- `resource_id`: a3-rust.yml (the workflow filename) 3. Call `download_workflow_run_artifact` with `resource_id:` set to the artifact ID.
- The tool returns workflow runs sorted by creation date (most recent first) 4. Extract the downloaded zip with `unzip` and read `tmp/verifier-output.txt`.
- Note the workflow run ID from the first result
2. **List and download the artifact**:
- Use the `list_workflow_run_artifacts` tool with:
- `owner`: NikolajBjorner
- `repo`: litebox
- `resource_id`: [the workflow run ID from step 1]
- This lists all artifacts for that run; find the one named `qsat-verifier-output`
- Use the `download_workflow_run_artifact` tool with:
- `owner`: NikolajBjorner
- `repo`: litebox
- `resource_id`: [the artifact ID]
- This downloads the artifact zip file (GitHub automatically adds .zip)
- Extract the zip file using bash commands (unzip is allowed) to access the contents
3. **Read the log file**:
- After extraction, the files will be in a `tmp/` subdirectory
- Read the contents of `tmp/verifier-output.txt`
- This file contains the output from the qsat verifier run

- This is a security-focused Rust sandboxing library - treat security bugs with priority - The a3-rust verifier uses static analysis and may have false positives
- The qsat verifier uses static analysis and may have false positives

## GitHub MCP Server Tools Reference ## Artifact Contents
You have access to the GitHub MCP server with the **actions toolset** enabled. Use these tools (NOT bash/curl): The `a3-rust-output` zip contains:
- `tmp/verifier-output.txt` - Main verifier output **(analyze this)**
### Available Tools:
1. **list_workflow_runs** - List workflow runs for a specific workflow
- Parameters: `owner`, `repo`, `resource_id` (workflow filename like `qsat-verifier.yml`)
- Returns: List of workflow runs sorted by creation date (newest first)
2. **list_workflow_run_artifacts** - List artifacts for a workflow run
- Parameters: `owner`, `repo`, `resource_id` (workflow run ID)
- Returns: List of artifacts with their IDs and names
3. **download_workflow_run_artifact** - Download a workflow artifact
- Parameters: `owner`, `repo`, `resource_id` (artifact ID)
- Returns: Download URL or zip file content
- Note: You can then use bash `unzip` command to extract the contents
### Workflow Context:
- Repository: `NikolajBjorner/litebox`
- Workflow file: `qsat-verifier.yml`
- Artifact name: `qsat-verifier-output`
The artifact zip contains:
- `tmp/verifier-output.txt` - Main log file with qsat verifier output (this is what you need to analyze)
- `tmp/build-output.txt` - Build log (optional reference) - `tmp/build-output.txt` - Build log (optional reference)
- `tmp/mir_files/*.mir` - MIR files (optional reference) - `tmp/mir_files/*.mir` - MIR files (optional reference)
- `tmp/mir_errors/*.err` - MIR error logs (optional reference) - `tmp/mir_errors/*.err` - MIR error logs (optional reference)
