CodePulse

Instant, safe code-quality fixes for Python, JavaScript/TypeScript, and Java — right in VS Code.

CodePulse detects 36 rule violations, auto-fixes the safe ones, and flags the rest with severity-coloured underlines. No config required. Works on save.

Features


Auto-fix on save	Fixes applied automatically when you save a supported file
Diff preview	`Cmd/Ctrl+Shift+D` — see exactly what will change before applying
Severity colours	🔴 CRITICAL (red) · 🟡 WARNING (yellow) · 🔵 INFO (blue) underlines
36 rules	Python · JS/TypeScript · Java — see Rule Catalog
Rule suppression	`# codepulse: ignore[P-ID-01]` to suppress on one line
Per-project config	`.codepulserc` to disable rules or override severities
Project scan	Scan all files at once with a health score

Configuration

// settings.json
{
  "codepulse.apiUrl": "https://your-api-url.amazonaws.com",
  "codepulse.enableOnSave": true,
  "codepulse.rules": {
    "P-ST-07": "off",     // disable long-function warning
    "P-CF-01": "info"     // downgrade to INFO
  }
}

Or use a .codepulserc file in your project root:

{
  "rules": {
    "P-ST-07": "off",
    "P-CF-01": "info"
  },
  "ignorePatterns": ["migrations/", "generated/"]
}

Rule Suppression

Suppress on a single line:

return datetime.now()  # codepulse: ignore[P-PY-02]

Suppress all rules on a line:

assert user is not None  # codepulse: ignore

Requirements

VS Code 1.95+
A deployed CodePulse API (or self-host — see CONTRIBUTING.md)

Privacy

CodePulse processes source code in-memory inside AWS Lambda (eu-north-1). No source code is stored, logged, or retained after the response returns.
