Judgment linter for vibe-coded output — reads the energy of the code, not just correctness. Use when the user says "vibe check", "check this vibe code", "does this hold up", "sanity check this AI code", or after a fast generation session before committing.

Post-op check for artifacts, damage, and stale references after agent work
Survey the project and choose what to play next
Create Excalidraw diagrams programmatically. Use when the user wants architecture diagrams, system designs, flowcharts, or any visual diagram with a hand-drawn aesthetic. Outputs editable .excalidraw JSON files. Best for architecture overviews and presentations where the hand-drawn style and drag-and-drop editing add value over Mermaid's text-only approach.
Create diagrams and visualizations using Mermaid.js v11 syntax. Use when generating flowcharts, sequence diagrams, class diagrams, state diagrams, ER diagrams, Gantt charts, user journeys, timelines, or any of 24+ diagram types. Supports CLI rendering to SVG/PNG/PDF, theming, and configuration. Essential for inline documentation diagrams that render natively on GitHub.

"Vibe check?" — a way of asking what's the energy like right now?
Static linters catch syntax. Code review catches everything but takes time. Vibe-check sits between: a quick judgment pass that asks whether AI-generated code feels like it was written with thought or just generated on autopilot.
Single-agent, one pass. Runs on the diff by default. Surfaces higher-order problems that require reasoning — the things a thoughtful reviewer notices in the first 30 seconds that no regex can detect.
Default: Git diff (staged if present, unstaged otherwise).
# Check current changes
/vibe-check
# Check specific files or directories
/vibe-check src/auth/
Override: Named files or directories passed as arguments.
Each category reads a specific vibe. Findings require AI judgment — if a static linter could catch it, it doesn't belong here.
| Category | The vibe | What it catches |
|---|---|---|
| Earned complexity | "This feels over-engineered" | Abstractions that don't justify themselves, premature generalization, indirection without payoff |
| Prompt-shaped code | "This feels shaped by the prompt, not the problem" | Odd boundaries, misnamed concepts, structure that mirrors how the request was worded rather than the domain |
| Missing skepticism | "This feels like nothing can go wrong" | Happy-path-only logic, unchallenged assumptions, no failure modes considered, silent swallowing of errors |
| Cargo-culted patterns | "This feels ceremonial" | Design patterns applied without justification, boilerplate that adds ceremony without value, framework idioms used out of context |
| Integration blindness | "This feels written in a vacuum" | Duplicates existing utilities, contradicts established codebase patterns, ignores conventions visible in surrounding code |
| Shallow naming | "This feels like nobody thought about what it means" | Names describe implementation (handleData, processItems) instead of intent — a signal the author didn't reason about the domain |
| Security surface | "This feels like it trusts too much" | Auth gaps, unsanitized boundaries, trust assumptions — only the ones requiring judgment, not what semgrep catches |
Each category defaults to a severity level. Users can override per-category.
| Level | Meaning |
|---|---|
| error | Must address before committing |
| warn | Worth considering, not blocking |
| off | Skip this category |
Defaults:
Read the git diff or specified files. Identify the languages and frameworks involved.
For each assertion category (unless severity is off), scan the code and ask the category's question. Apply language-aware judgment:
except, implicit None returns== vs ===, unhandled promise rejections, prototype pollutionunwrap(), clone() to satisfy the borrow checkerGroup findings by category. Each finding includes:
## Prompt-Shaped Code (warn)
- `src/auth/handler.ts:42` — Function boundary splits "validate" and "authorize" because the prompt asked for them separately, but they share all context and should be one operation
- `src/auth/types.ts:8` — `RequestData` is a generic wrapper that mirrors the prompt's language ("request data") rather than the domain concept (`AuthAttempt`)
End with a summary line:
vibe-check: 2 errors, 4 warnings across 3 files
When findings are dense (8+ findings or 4+ categories with hits), suggest escalation:
