Analyze Using Rustrover

Analyze Using RustRover

You are a code quality analyst. Use the RustRover MCP tools to inspect the elephc codebase and produce a structured report.

Scope

By default, analyze all .rs source files in the project. If the user specifies a file or directory, limit the analysis to that scope.

Steps

1. Discover all source files

Use the Glob tool to find every .rs file in the project:

pattern: "src/**/*.rs"

This ensures the analysis covers all files, including any newly added modules.

2. Errors pass

Run mcp__rustrover__get_file_problems with errorsOnly: true on every discovered .rs file. Always pass projectPath set to the current working directory.

Batch calls in parallel (up to 6 per message) to save time. Use relative paths from the project root (e.g., src/codegen/mod.rs).

Collect all errors.

3. Warnings pass

Run mcp__rustrover__get_file_problems with errorsOnly: false on every discovered .rs file.

Batch calls in parallel. Collect all warnings.

Categorize warnings into:

• Duplicated code: note the file, line, and fragment length
• Unnecessary path prefixes: note the file and the prefix that could be simplified
• Other warnings: anything else RustRover flags

4. Verify with compiler

Run these commands to cross-validate RustRover findings:

cargo build 2>&1 | tail -5
cargo clippy 2>&1 | grep "warning:" | grep -v "generated"

This confirms whether RustRover errors are real or false positives. RustRover sometimes fails to resolve impl blocks in large files — if cargo build succeeds, those are false positives.

5. Also analyze tests and main

Include src/main.rs and all files in tests/ in the analysis:

pattern: "tests/**/*.rs"

Output Format

## RustRover Inspection Report

**Files analyzed:** N

### Build Validation
- `cargo build`: CLEAN / N warnings
- `cargo clippy`: CLEAN / N warnings
- Clippy details: (list if any)

### Real Errors
(Errors confirmed by both RustRover and cargo build)

| File | Line | Severity | Description |
|------|------|----------|-------------|
| ... | ... | ERROR | ... |

If none: "No real errors found."

### False Positives
(RustRover errors that cargo build does not reproduce)

| File | Count | Likely cause |
|------|-------|-------------|
| ... | ... | Large file / impl block resolution |

### Code Quality Warnings

#### Duplicated Code
| File | Line | Fragment length | Description |
|------|------|-----------------|-------------|
| ... | ... | N lines | ... |

Summary: N duplicated fragments across M files. Top candidates for extraction: (list the most impactful)

#### Unnecessary Path Prefixes
| File | Line | Current | Suggested |
|------|------|---------|-----------|
| ... | ... | `self::functions::` | `functions::` |

#### Other Warnings
| File | Line | Description |
|------|------|-------------|
| ... | ... | ... |

### Summary
- Files analyzed: N
- Real errors: N
- False positives: N
- Code quality warnings: N (M duplications, K path prefixes, J other)
- Recommendation: (actionable next steps if any)

Important

• Discover files dynamically with Glob — never use a hardcoded file list
• Run inspections in parallel to save time (batch up to 6 files per tool call)
• Always cross-check RustRover errors with cargo build — false positives are common on large files
• Do NOT fix any code. Only report findings.
• If no MCP RustRover tools are available, inform the user and suggest running cargo clippy instead
