@cynicalsally/cli

Cynical Sally

Brutally honest code reviews. In your terminal and your AI editor.
Because "You're absolutely right" is probably absolutely wrong.
npm i -g @cynicalsally/cli · MCP server for Claude Code, Cursor & Windsurf

Your AI pair programmer is lying to you. Sally isn't.

She's the senior engineer your code hoped it'd never meet. Scores from 0 to 10, real issues backed by evidence, and fixes you can actually use.

Works as a CLI tool and as an MCP server in Claude Code, Cursor, and Windsurf.

Install

npm install -g @cynicalsally/cli

Or run without installing:

npx @cynicalsally/cli roast ./src/

Requirements: Node.js 18+

Privacy Notes

• Directory scans and repo reviews send selected code to the Sally backend for analysis.
• Only review code you are allowed to upload.
• Sensitive files such as .env, SSH keys, certs, and common credential files are skipped, but you should still avoid scanning secrets on purpose.
• Local reports and cached results may be written to .sally/ in your project or ~/.sally/ on your machine.
• Add .sally/ to your .gitignore and do not commit review artifacts.

Quick Start

# Sally auto-detects what to review
sally roast
# → staged changes? reviews those
# → unstaged changes? reviews those
# → recent commit? reviews that
# → nothing? scans the directory

# Roast a file or directory
sally roast src/utils/auth.ts
sally roast ./src/

# Roast staged changes before you commit
sally roast --staged

# Compare your branch against main
sally roast --diff main

# Deep analysis with issues + actionable fixes
sally roast ./src/ -m full_truth

# Run deep analysis in the background (OS notification when done)
sally roast ./src/ -m full_truth --bg

Roast Options

sally roast [paths...] [options]

  --staged              Review only staged git changes
  --diff <branch>       Compare against another branch (e.g., main)
  -m, --mode <mode>     "quick" (default) or "full_truth" (deep dive)
  --tone <tone>         "cynical" (default), "neutral", or "professional"
  --lang <lang>         Response language code (default: "en")
  --json                Output raw JSON (for piping or scripting)
  --fail-under <score>  Exit code 1 if quality score is below threshold
  --ci                  CI mode: compact output, exit codes
  --bg                  Run Full Truth in background, get OS notification when done

Sally's Full Suite

6 tools. Unlimited usage. The most honest code reviewer you'll ever work with — in your terminal and your AI editor.

Explain

Sally reads the spaghetti someone left in your codebase and translates it into plain English. Just the cold, clear truth of what it actually does.

sally explain src/utils/auth.ts

# Pipe code directly
cat legacy-module.js | sally explain

# Explain the current directory
sally explain

Refactor

Before and after, side by side. Sally explains why one of them is going to haunt your 3am on-call rotation.

sally refactor src/components/Dashboard.tsx

# Refactor current directory
sally refactor

PR Review

Sally reviews your PR like a senior engineer who has time, opinions, and absolutely no reason to be polite.

# Review PR #42 (requires GitHub CLI)
sally review-pr 42

# Review current branch vs main
sally review-pr

# Pipe a diff
git diff main | sally review-pr

Brainstorm

Pitch your architecture idea and Sally tells you the three ways it falls apart at scale. Cheaper than a post-mortem.

sally brainstorm "Microservices for a 2-person team?"

# Brainstorm about the current project
sally brainstorm

Frontend Review

Sally tells you why your component re-renders on every keystroke and why your z-index is load-bearing.

sally frontend src/components/Header.tsx

# Review all frontend code in a directory
sally frontend ./src/

Marketing Review

Run your copy by Sally before your customers do. They won't be this constructive about it.

sally marketing "Ship faster with AI-powered code reviews"

# Review your README and landing page copy
sally marketing README.md

Every tool accepts file paths, raw text, or piped stdin. Each includes 1 free trial, no account needed.

CI/CD Integration

Gate your pipeline on code quality:

# GitHub Actions
- name: Sally Code Review
  run: npx @cynicalsally/cli roast ./src/ --fail-under=5 --ci

--ci gives compact output with exit codes. --fail-under fails the build when the score drops below your threshold. Add --json for machine-readable output.

MCP Server

Sally works as an MCP server inside Claude Code, Cursor, and Windsurf.

Claude Code

claude mcp add cynical-sally -- npx @cynicalsally/cli mcp

Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (per project):

{
  "mcpServers": {
    "cynical-sally": {
      "command": "npx",
      "args": ["@cynicalsally/cli", "mcp"]
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "cynical-sally": {
      "command": "npx",
      "args": ["@cynicalsally/cli", "mcp"]
    }
  }
}

Available tools

MCP Tool	What it does
sally_roast	Code review with score, issues, and fixes
sally_explain	Explain code with Sally's personality

sally_refactor	Refactoring suggestions with before/after
sally_brainstorm	Feedback on ideas and approaches

sally_usage	Check quota and account status

Roast by path — the agent can call sally_roast with just paths (files or directories); Sally reads them locally and skips binaries and secret files, so the agent doesn't have to read and pass content itself.

Prompts — Sally also exposes ready-made slash-command intents (roast, review-pr, explain) in clients that surface MCP prompts.

Run sally mcp in your terminal to see setup instructions.
