> A Flake8 plugin for the emotional and spiritual correctness of your Python code.

## Overview

`flake8-vibes` is a Flake8 plugin that performs vibe analysis on your codebase. Unlike traditional linters that concern themselves with correctness, style, or performance, `flake8-vibes` focuses on what really matters: whether your code is okay (emotionally).

Your code can be PEP 8 compliant, fully typed, and 100% test-covered while still being, energetically speaking, a disaster. This plugin surfaces those issues.

It integrates via Flake8's standard entry point system, ships a `vibe-check` CLI for full codebase readings, and produces violation messages that are specific, accurate, and not particularly gentle.

## Key Features

- **33 rules across 8 categories** — naming crimes, boolean chaos, exception dishonesty, complexity, hardcoding, docstring energy, and temporal risk
- **Git-aware authorship detection** — `git blame` tells VIB001 exactly who wrote that function on a Thursday
- **`vibe-check` CLI** — per-file progress bars, scores, verdicts, and a final reckoning
- **Standard Flake8 integration** — `flake8 --select=VIB`, works with your existing config and CI
- **`# noqa: VIBXXX` suppression** — same as every other Flake8 rule; no special treatment
- **Randomised violation messages** — every rule ships at least 2 messages and picks between them, so the shame stays fresh
- **VS Code extension** — squiggles, hover messages, and inline judgment without leaving the editor
- **Git pre-commit hook** — appends the vibe score to every commit message, so the score lives in the history forever

## Rules

### Temporal Risk (`VIB001`) — thursday-energy

Thursdays occupy a liminal position in the work week: close enough to Friday to generate ambition, far enough from Monday to have accumulated significant psychological debt. Functions written on Thursdays tend toward overengineering, premature abstraction, and a particular kind of confidence that the coming weekend will not resolve.

VIB001 flags functions exceeding 20 lines authored on a Thursday, as identified by `git blame` or, for untracked files, the system clock at lint time.

```
VIB001 thursday energy detected: 'process_invoice_batch' is 34 lines of pure thursday hubris. we felt it. the diff felt it.
VIB001 thursday energy: 'parse_user_preferences' shouldn't exist, and yet here we are, on a thursday, making it longer.
```

### Technical Debt (`VIB002`) — todo-shame

A `TODO` is a dream with a comment attached. A `FIXME` is a bug with good self-awareness. Acknowledging a problem and solving it are not the same thing, and the diff doesn't care which one you did.

```
VIB002 todo shame: this TODO has survived more sprints than some of your teammates
VIB002 todo shame: FIXME: acknowledged, unaddressed, unforgiven, and now publicly humiliated
```

### Naming Crimes (`VIB013–VIB020`)

Eight rules covering the full taxonomy of names that describe shape instead of purpose. A variable named `data` is a box labelled "box." A class named `UserManager` manages something — the question is what.

| Rule | Pattern | Charge |
|------|---------|--------|
| VIB013 | `data`, `result`, `info`, `stuff`, `obj` | holds everything, describes nothing |
| VIB014 | single-letter names outside loops | zero semantic content |
| VIB015 | `tmp`, `temp` | temporary names for permanent residents |
| VIB016 | `new_` prefix | implies an `old_` that does not exist |
| VIB017 | `flag` variables | name what the boolean actually represents |
| VIB018 | `final_` prefix | nothing is final |
| VIB019 | `Abstract*` base classes | the abstraction is not the achievement |
| VIB020 | `*Manager`, `*Handler` classes | manages what, exactly |

```
VIB013 naming crime: `data` holds everything and describes absolutely nothing. a true void.
VIB016 naming crime: `new_user` implies there is an `old_user`. there isn't.
VIB018 naming crime: `final_result` — the hubris of `final` in a variable name that will be changed twice before lunch.
VIB020 naming crime: `UserManager` manages something. the question is what.
```

### Boolean Chaos (`VIB081–VIB084`)

Four patterns that are technically valid and spiritually wrong. Python has boolean literals, the `not` keyword, and `is None`. Using them is not optional.

- **VIB081** `== True` — you already have a boolean. what more do you need.
- **VIB082** `== False` — `not x` exists. it is right there.
- **VIB083** `== None` — `None` is a singleton. you compare singletons with `is`, not `==`.
- **VIB084** `not x == y` — this is `x != y` with extra steps and worse energy.

```
VIB081 boolean chaos: `== True` — you already have a boolean, what more do you need.
VIB083 boolean chaos: None is a singleton. you don't compare singletons with `==`. this is non-negotiable.
```

### Exception Handling (`VIB041–VIB043`)

Bare `except:` clauses, `pass` inside except blocks, and catching `Exception` as a base class. The exception system exists to give you information. Discarding it is not error handling — it's optimism with syntax.

```
VIB041 bare except: you caught everything. you handled nothing. bold move.
VIB042 silent except: `pass` in an except block is a lie you tell yourself and everyone who reads this code after you.
```

### Complexity (`VIB031–VIB032`)

Nesting beyond 4 levels and functions with more than 3 return statements. Code that requires spatial reasoning to navigate is code that is asking to be broken up.

```
VIB031 nesting crimes: this function has 5 levels of indentation. no one is having a good time in here.
VIB032 return chaos: 4 return statements in one function. pick a path.
```

### Hardcoding (`VIB033–VIB036`)

Magic numbers, hardcoded ports, localhost strings, and hardcoded file paths. Configuration belongs in configuration. The number `8080` means something — give it a name so the next person doesn't have to guess.

### Docstring Energy (`VIB051–VIB054`)

Docstrings that restate the function name, open with "this function", or end without punctuation. A docstring should explain *why*, not transcribe *what*. If the docstring and the function signature say the same thing, one of them is redundant.

## Demo

```
$ vibe-check ./src

Total violations: 7

Per-file breakdown:

Django is the only one that cleared 50. Ruff lints everything except, apparently, itself. Pandas has 56,653 violations, which tracks.
