AI SLOP Detector — VS Code Extension v3.2.1

Real-time AI-generated code quality analysis inside VS Code. Surfaces deficit scores, structural anti-patterns, ML signals, clone detection, and actionable diagnostics without leaving your editor.

What's New in v3.2.1

LEDA Self-Evolving Configuration Loop

The biggest addition: the extension now exposes the LEDA calibration loop — the engine that learns your codebase's unique coding style and automatically tunes its own detection weights.

Bootstrap Config (slop-detector.initConfig): Generates a .slopconfig.yaml in your workspace root with domain-specific overrides and secure .gitignore injection. Run this once on a new project.
Self-Calibrate (slop-detector.selfCalibrate): Runs the 4D grid-search calibration (LDR × Inflation × DDC × Purity) against your analysis history, shows the result in the Output panel, and offers a one-click Apply button to write the optimal weights back to .slopconfig.yaml.

The more you use it, the smarter it gets. After 10+ analyses the LEDA engine reverse-engineers your team's past behavior and Git history to derive mathematically optimal weights. Run self-calibrate periodically — it evolves with your codebase.

Purity Dimension (4D Scoring)

The Purity score (exp(−0.5 × n_critical)) is now visible everywhere:

Diagnostics summary — appended after LDR / Inflation / DDC
Status bar tooltip — shows Purity: 0.xxx (N critical)

This completes the 4D metric display: LDR + Inflation + DDC + Purity.

Other v3.2.1 Fixes

calibrate() min_events guard: correctly handles fewer events than the minimum without raising, returns insufficient_data status
Git noise filter (P2): per-file deduplication prevents FP overcounting across runs
Black + ruff CI green across all source files

What's New in v3.1.1

Clone Detection in Core Metrics: function_clone_cluster results are now visible in the Core Metrics summary row — CRITICAL/PASS at a glance.
Workspace QuickPick: "Analyze Workspace" now shows a sorted QuickPick list of deficit files. Click any file to open it directly in the editor.
JSON parse fix: extractJson() strips [INFO] log lines before parsing.
History Trends formatting: formatted column table (Runs / Latest / Best / Worst / Trend) replaces raw JSON dump.

Features

Inline Diagnostics (Problems Panel)

Every analysis run produces structured diagnostics in the Problems panel:

Source label	Diagnostic type	Severity
SLOP Detector	Summary: score, status, LDR/ICR/DDC/Purity, ML score, Clone	Error / Warning / Info
SLOP Detector - Inflation	Unjustified jargon term at exact line	Warning
SLOP Detector - Docstring	Over-documented function (doc/impl ratio)	Error / Warning
SLOP Detector - Evidence	Unjustified quality claim lacking evidence	Warning
SLOP Detector - DDC	Unused imports summary	Info
SLOP Detector - Patterns	Structural anti-patterns (god_function, dead_code, phantom_import, function_clone_cluster, etc.)	Error / Warning / Info

Pattern diagnostics use pattern_id as the diagnostic code — VS Code's Problems panel filter works natively (e.g., filter for god_function only).

Status Bar

Right side of the status bar shows live quality at a glance:

$(check) Good (12.4)      <- score below warn threshold
$(warning) Warning (34.1) <- score >= warnThreshold
$(error) Error (67.8)     <- score >= failThreshold
$(sync~spin) Analyzing... <- analysis in progress

Tooltip includes:

Deficit Score and Status
LDR / Inflation / DDC / Purity metric values
ML slop probability (when model is present)
Clone Detection: PASS or CRITICAL

Workspace Analysis (QuickPick)

"Analyze Workspace" scans all Python files and opens an interactive QuickPick:

$(error) src/slop_detector/cli.py          [67.8] INFLATED_SIGNAL
$(warning) src/slop_detector/core.py       [34.1] SUSPICIOUS
$(check) src/slop_detector/models.py       [11.2] CLEAN

Click any entry to open the file directly in the editor.

Installation

From Marketplace

Search "AI SLOP Detector" in the VS Code Extensions panel, or:

ext install Flamehaven.vscode-slop-detector

From VSIX (Local)

code --install-extension vscode-slop-detector-3.2.1.vsix

Requirements

Python 3.9+
ai-slop-detector installed in the Python environment VS Code uses:

pip install ai-slop-detector          # core only
pip install "ai-slop-detector[ml]"    # + ML secondary signal
pip install "ai-slop-detector[js]"    # + JS/TS tree-sitter patterns
pip install "ai-slop-detector[full]"  # everything

The extension invokes python -m slop_detector.cli <file> --json internally. Set slopDetector.pythonPath if your Python interpreter is not on PATH.

Configuration

Open Settings (Ctrl+,) and search "SLOP Detector", or edit settings.json:

{
  "slopDetector.enable": true,
  "slopDetector.lintOnSave": true,
  "slopDetector.lintOnType": false,
  "slopDetector.showInlineWarnings": true,
  "slopDetector.failThreshold": 50.0,       // deficit_score >= 50 -> Error
  "slopDetector.warnThreshold": 30.0,       // deficit_score >= 30 -> Warning
  "slopDetector.pythonPath": "python",
  "slopDetector.configPath": "",            // path to .slopconfig.yaml (optional)
  "slopDetector.recordHistory": true,       // write results to ~/.slop-detector/history.db
  "slopDetector.showCalibrationHints": true // notify when LEDA calibration milestone is reached
}

Deficit Score Thresholds

Status	deficit_score
CLEAN	< 30
SUSPICIOUS	30 – 49
INFLATED_SIGNAL	50 – 69
CRITICAL_DEFICIT	>= 70

Recommended: warnThreshold: 30, failThreshold: 50 (defaults).

Pattern Reference (v3.2.1 — 27 patterns)

Use the pattern_id as a Problems panel filter code.

Placeholder / Stub

pass_placeholder — function body is only pass
ellipsis_placeholder — function body is only ...

return_none_placeholder — function body is only return None
return_constant_stub — function body is return <literal>
todo_comment — inline # TODO
fixme_comment — inline # FIXME
hack_comment — inline # HACK
xxx_comment — inline # XXX

Structural

god_function — >50 logic lines or cyclomatic complexity >10
dead_code — statements after return/raise/break/continue
deep_nesting — control-flow depth >4

interface_only_class — class with ≥50% placeholder methods
nested_complexity — deep nesting AND high cyclomatic complexity combined
placeholder_variable_naming — numbered variable sequences (data1, data2…)

Quality

phantom_import — import that cannot be resolved (hallucinated dependency)
function_clone_cluster — structurally identical function bodies (AST JSD)

Cross-Language

js_var_usage — JavaScript var in Python file
js_console_log — console.log in Python file
ruby_array_each — Ruby-style .each block
go_print_format — Go fmt.Printf style

Lint Escape

noqa_overuse — excessive # noqa suppression
