Code intelligence tool — fix, scan, and advise on Python, JSON, YAML, and Rust (advisory)

imodent

Code intelligence tool — fix, scan, and advise on Python, JSON, JSONL, and YAML files.

imodent is a fast first-look mapper and conservative fixer. It is useful for finding syntax blockers, import hygiene issues, lint-backed risks, and areas that need review. It does not replace deeper codegraph or model-assisted code understanding.

Features

• Auto-detection: Detects Python, JSON, JSONL, YAML automatically
• AST-based fixing: Python code fixed with Black, validated with ast.parse()
• Import analysis: Detect unused, duplicate, and misused imports — with 5 fix options (delete, keep, investigate, false-positive, keep-typing)
• Ruff-backed lint evidence: Attach external lint diagnostics to scan findings
• Confidence output: Show decision candidates with evidence, confidence, and destructive-action policy
• Architecture advisor: Circular dependency detection, import clustering warnings
• Pre-flight checks: Refuses to "fix" structurally broken code (use --force to override)
• Extensible: Add new languages via @StrategyRegistry.register — no core changes needed
• CLI: Two modes — FIX (default) and SCAN (--analyze)

Install

pip install -e .
# or system-wide:
pipx install .

Usage

FIX mode — reformat & repair files

# Fix a file with backup
imodent myfile.py --backup

# Preview changes without writing
imodent myfile.py --dry-run

# Syntax check only
imodent myfile.py --check

# Recursive directory scan
imodent ./src --recursive --indent 2 --backup

# Fix structurally broken code (skips pre-flight check)
imodent broken.py --force

SCAN mode — project-wide analysis

# Find unused & duplicate imports
imodent ./src --analyze --imports

# Review without modifying files
imodent ./src --report

# Add Ruff-backed lint evidence
imodent ./src --analyze --imports --lint --report

# Show confidence-weighted decision candidates
imodent ./src --analyze --imports --lint --confidence --report

# Flag architectural issues
imodent ./src --analyze --advisory

# Auto-fix safe findings (analysis implied)
imodent ./src --fix

# Auto-fix safe findings with explicit import analysis
imodent ./src --analyze --imports --fix

# Full audit + fix
imodent ./src --analyze --imports --advisory --fix

SCAN mode always recurses into subdirectories. --report, --confidence, --imports, --lint, --advisory, --interactive, and --fix all route to SCAN mode. -b, -n, and -c also work with scan fixes. -r and --force are FIX-mode controls; when used with scan flags, imodent prints a note.

Import analysis options

When --imports finds an unused import, interactive mode can offer review choices such as:

Option	When to use
delete	Import is genuinely unused
keep	Type hints, re-exports, __all__ entries
keep-typing	Import is kept specifically for type annotations
investigate	Search codebase before deciding
false-positive	Analysis missed a usage (dynamic import, string reference)

Non-interactive --fix only applies findings marked safe by the fixer. Most unused-import candidates remain review-only unless the tool has enough evidence to avoid deleting intent.

Python API

from imodent import FixPipeline

pipeline = FixPipeline(indent_size=4)

# Fix content (auto-detects language)
result = pipeline.fix(messy_code)
if result.success:
    print(result.content)
else:
    for error in result.errors:
        print(f"Error: {error}")

# Force fix on structurally broken code
result = pipeline.fix(broken_code, force=True)

Analysis API

from pathlib import Path

from imodent import AnalysisCoordinator

coordinator = AnalysisCoordinator()
result = coordinator.analyze([Path("src/")])

for finding in result.findings:
    print(f"{finding.severity.value}: {finding.message}")

Add a New Language

from imodent.interfaces import LanguageStrategy, FixResult
from imodent.registry import StrategyRegistry


@StrategyRegistry.register
class TOMLStrategy(LanguageStrategy):
    @property
    def name(self) -> str:
        return "toml"

    @property
    def extensions(self) -> list[str]:
        return [".toml"]

    def detect(self, content: str) -> bool:
        return "[[" in content or "=" in content

    def fix(self, content: str, indent_size: int = 4, force: bool = False) -> FixResult:
        # Your fixing logic
        return FixResult(
            success=True,
            content=content,
            errors=[],
            warnings=[],
            original_valid=True,
            fixed_valid=True,
        )

    def validate(self, content: str) -> tuple[bool, str | None]:
        return True, None

No core changes needed — the strategy auto-registers and the pipeline picks it up.

CLI Reference

Flag	Mode	Description	Default
-i N	FIX	Indent size (spaces)	4
-b	FIX	Create .bak backup	off
-n	FIX	Dry run (preview only)	off
-c	FIX	Check only (no fix)	off
-r	FIX	Recursive directory scan	off
--force	FIX	Attempt fix on structurally broken code	off
--analyze	SCAN	Enable project-wide analysis	off
--imports	SCAN	Detect import issues	off
--lint	SCAN	Run lint checks	off
--advisory	SCAN	Flag architectural issues	off
--fix	SCAN	Auto-fix safe findings	off
--interactive	SCAN	Prompt before each fix	off
--report	SCAN	Review findings without modifying files	off
--confidence	SCAN	Show evidence-backed decision candidates	off
-v	SCAN	Show all findings	off

-b, -n, and -c are shared controls when scan fixes are enabled. --check prevents --fix from applying changes and prints a note explaining the conflict.

Supported Formats

Format	Detection	Fixing	Validation
Python	Keywords + AST parse	Black → AST heuristic	ast.parse()
JSON	{/[ + json.loads()	Pretty-print with indent	json.loads()
JSONL	Each line valid JSON	Compact each line	json.loads() per line
YAML	--- or key patterns + yaml.safe_load()	Pretty-print with proper list indent	yaml.safe_load()

Known Limitations

• Confidence is rule-based, not proof of developer intent.
• Fragmented workspaces with multiple import roots can produce ambiguous import findings.
• Type-only or quoted annotation issues may need human review even when Ruff reports them as F821.
• Default scan discovery skips common generated artifacts and test files; run targeted paths when you want to inspect those.
• Use codegraph or manual review for deep impact analysis. imodent is the fast mapper and conservative hygiene layer.
