Documentation Overview

Judges Panel

An MCP (Model Context Protocol) server that provides a panel of 45 specialized judges to evaluate AI-generated code — acting as an independent quality gate regardless of which project is being reviewed. Combines deterministic pattern matching & AST analysis (instant, offline, zero LLM calls) with LLM-powered deep-review prompts that let your AI assistant perform expert-persona analysis across all 45 domains.

Highlights:

Includes an App Builder Workflow (3-step) demo for release decisions, plain-language risk summaries, and prioritized fixes — see Try the Demo.
Includes V2 context-aware evaluation with policy profiles, evidence calibration, specialty feedback, confidence scoring, and uncertainty reporting.
Includes public repository URL reporting to clone a repo, run the full tribunal, and output a consolidated markdown report.
200+ deterministic auto-fix patches (see src/patches/index.ts) plus LLM-powered deep review.

🧪 Many commands in printHelp are experimental/roadmap. By default, we show GA commands only. Set JUDGES_SHOW_EXPERIMENTAL=1 to reveal stubs; these may not be wired yet.

🔰 Packages

CLI: @kevinrabun/judges-cli → binary judges (use npx @kevinrabun/judges-cli eval --file app.ts).

MCP/API: @kevinrabun/judges → programmatic API + MCP server (npm install @kevinrabun/judges).

VS Code extension: see vscode-extension/.

GitHub Action: uses: KevinRabun/judges@main (see CI quickstart).

Quickstart

CLI (one-off)

bash

# Using the CLI package (recommended)
npx @kevinrabun/judges-cli eval --file src/app.ts

# Show GA commands only (default)
npx @kevinrabun/judges-cli --help

# Show experimental/roadmap commands
echo "JUDGES_SHOW_EXPERIMENTAL=1" >> $GITHUB_ENV
npx @kevinrabun/judges-cli --help

# License scan (supply-chain & license compliance)
npx @kevinrabun/judges-cli license-scan --dir .

CLI vs API: If you want to embed Judges in your app (MCP/API), install @kevinrabun/judges. For the command-line, use @kevinrabun/judges-cli (binary judges).

GitHub Action

yaml

name: Judges
on: [pull_request, push]
jobs:
  judges:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: KevinRabun/judges@main
        with:
          path: .
          diff-only: true           # evaluate only changed lines in PRs (default true)
          fail-on-findings: true    # fail on critical/high findings
          upload-sarif: true        # upload SARIF to GitHub Code Scanning

Programmatic API (MCP server included)

Terminal

npm install @kevinrabun/judges

server.ts

import { evaluateCode } from "@kevinrabun/judges/api";
const verdict = evaluateCode("const password = 'ProdSecret';", "typescript");
console.log(verdict.overallVerdict, verdict.overallScore);

MCP server

The MCP server runs on stdio and is started by your MCP client (VS Code, Claude Desktop, etc.). Configure it in your MCP settings (e.g. mcp.json):

config.json

{
  "servers": {
    "judges": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@kevinrabun/judges"]
    }
  }
}

Or run the server directly:

Terminal

npx @kevinrabun/judges
# Starts the MCP server on stdio

Config file: .judgesrc.json (supports ${ENV_VAR} substitution via expandEnvPlaceholders). See Configuration.

Why Judges?

AI code generators (Copilot, Cursor, Claude, ChatGPT, etc.) write code fast — but they routinely produce insecure defaults, missing auth, hardcoded secrets, and poor error handling. Human reviewers catch some of this, but nobody reviews 45 dimensions consistently.

	ESLint / Biome	SonarQube	Semgrep / CodeQL	Judges
Scope	Style + some bugs	Bugs + code smells	Security patterns	45 domains: security, cost, compliance, a11y, API design, cloud, UX, …
AI-generated code focus	No	No	Partial	Purpose-built for AI output failure modes
Setup	Config per project	Server + scanner	Cloud or local	One command: `npx @kevinrabun/judges-cli eval file.ts`
Auto-fix patches	Some	No	No	200+ deterministic patches — instant, offline
Non-technical output	No	Dashboard	No	Plain-language findings with What/Why/Next
MCP native	No	No	No	Yes — works inside Copilot, Claude, Cursor
SARIF output	No	Yes	Yes	Yes — upload to GitHub Code Scanning
Cost	Free	$$$$	Free/paid	Free / MIT

Judges doesn't replace linters — it covers the dimensions linters don't: authentication strategy, data sovereignty, cost patterns, accessibility, framework-specific anti-patterns, and architectural issues across multiple files.

Judges — Terminal Output

Quick Start

Prereqs: Node.js >=18 (>=20 recommended), npx available. The judges CLI binary ships with @kevinrabun/judges-cli (preferred) and also works via npx @kevinrabun/judges.

Packages:

CLI: npm install -g @kevinrabun/judges-cli (or npx @kevinrabun/judges-cli ...)

MCP/API: npm install @kevinrabun/judges

Use @kevinrabun/judges for the MCP server and programmatic API. Use @kevinrabun/judges-cli when you want the judges terminal command.

GitHub App (self-hosted webhook)

Run a zero-config PR reviewer as a GitHub App:

bash

# Run the webhook server locally
judges app serve --port 4567

Required env vars:

JUDGES_APP_ID – GitHub App ID
JUDGES_PRIVATE_KEY or JUDGES_PRIVATE_KEY_PATH – PEM private key
JUDGES_WEBHOOK_SECRET – signature verification secret

Optional:

JUDGES_MIN_SEVERITY (default: medium)
JUDGES_MAX_COMMENTS (default: 25)
JUDGES_TEST_DRY_RUN=1 to avoid live network calls during tests

For local testing, you can expose http://localhost:4567/webhook via ngrok http 4567 and configure the GitHub App webhook URL accordingly.

Use in GitHub Actions

Add Judges to your CI pipeline with zero configuration:

yaml

# .github/workflows/judges.yml
name: Judges Code Review
on: [pull_request]

jobs:
  judges:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      security-events: write  # only if using upload-sarif
    steps:
      - uses: actions/checkout@v4
      - uses: KevinRabun/judges@main
        with:
          path: src/api.ts        # file or directory
          format: text             # text | json | sarif | markdown
          upload-sarif: true       # upload to GitHub Code Scanning
          fail-on-findings: true   # fail CI on critical/high findings

Outputs available for downstream steps: verdict, score, findings, critical, high, sarif-file.

Use with Docker (no Node.js required)

bash

# Build the image
docker build -t judges .

# Evaluate a local file
docker run --rm -v $(pwd):/code judges eval --file /code/app.ts

# Pipe from stdin
cat api.py | docker run --rm -i judges eval --language python

# List judges
docker run --rm judges list

Or use as an MCP server

1. Install and Build

bash

git clone https://github.com/KevinRabun/judges.git
cd judges
npm install
npm run build

2. Try the Demo

Run the included demo to see all 45 judges evaluate a purposely flawed API server:

Terminal

npm run demo

This evaluates examples/sample-vulnerable-api.ts — a file intentionally packed with security holes, performance anti-patterns, and code quality issues — and prints a full verdict with per-judge scores and findings.

The demo now also includes an App Builder Workflow (3-step) section. In a single run, you get both tribunal output and workflow output:

Release decision (Ship now / Ship with caution / Do not ship)
Plain-language summaries of top risks
Prioritized remediation tasks and AI-fixable P0/P1 items

3. Run the Tests

Terminal

npm test

Runs automated tests covering all judges, AST parsers, markdown formatters, and edge cases.

4. Connect to Your Editor

VS Code (recommended — zero config)

Install the Judges Panel extension from the Marketplace. It provides:

Inline diagnostics & quick-fixes on every file save
@judges chat participant — type @judges in Copilot Chat, or just ask for a "judges panel review" and Copilot routes automatically
Auto-configured MCP server — all 45 expert-persona prompts available to Copilot with zero setup

bash

code --install-extension kevinrabun.judges-panel

VS Code — manual MCP config

If you prefer explicit workspace config (or want teammates without the extension to benefit), create .vscode/mcp.json:

config.json

{
  "servers": {
    "judges": {
      "command": "npx",
      "args": ["-y", "@kevinrabun/judges"]
    }
  }
}

Claude Desktop

Add to claude_desktop_config.json:

config.json

{
  "mcpServers": {
    "judges": {
      "command": "npx",
      "args": ["-y", "@kevinrabun/judges"]
    }
  }
}

Cursor / other MCP clients

Use the same npx command for any MCP-compatible client:

config.json

{
  "command": "npx",
  "args": ["-y", "@kevinrabun/judges"]
}

5. Use Judges in GitHub Copilot PR Reviews

Yes — users can include Judges as part of GitHub-based review workflows, with one important caveat:

The hosted copilot-pull-request-reviewer on GitHub does not currently let you directly attach arbitrary local MCP servers the same way VS Code does.
The practical pattern is to run Judges in CI on each PR, publish a report/check, and have Copilot + human reviewers use that output during review.

Option A (recommended): PR workflow check + report artifact

Create .github/workflows/judges-pr-review.yml:

server.ts

name: Judges PR Review

on:
  pull_request:
    types: [opened, synchronize, reopened]

jobs:
  judges:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      pull-requests: write

    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Setup Node
        uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: npm

      - name: Install
        run: npm ci

      - name: Generate Judges report
        run: |
          npx tsx -e "import { generateRepoReportFromLocalPath } from './src/reports/public-repo-report.ts';
          const result = generateRepoReportFromLocalPath({
            repoPath: process.cwd(),
            outputPath: 'judges-pr-report.md',
            maxFiles: 600,
            maxFindingsInReport: 150,
          });
          console.log('Overall:', result.overallVerdict, result.averageScore);"

      - name: Upload report artifact
        uses: actions/upload-artifact@v4
        with:
          name: judges-pr-report
          path: judges-pr-report.md

This gives every PR a reproducible Judges output your team (and Copilot) can reference.

Option B: Add Copilot custom instructions in-repo

Add .github/instructions/judges.instructions.md with guidance such as:

markdown

When reviewing pull requests:
1. Read the latest Judges report artifact/check output first.
2. Prioritize CRITICAL and HIGH findings in remediation guidance.
3. If findings conflict, defer to security/compliance-related Judges.
4. Include rule IDs (e.g., DATA-001, CYBER-004) in suggested fixes.

This helps keep Copilot feedback aligned with Judges findings.

How It Works

The tribunal operates in three layers:

Pattern-Based Analysis — All tools (evaluate_code, evaluate_code_single_judge, evaluate_project, evaluate_diff) perform heuristic analysis using regex pattern matching to catch common anti-patterns. This layer is instant, deterministic, and runs entirely offline with zero external API calls.
AST-Based Structural Analysis — The Code Structure judge (STRUCT-* rules) uses real Abstract Syntax Tree parsing to measure cyclomatic complexity, nesting depth, function length, parameter count, dead code, and type safety with precision that regex cannot achieve. All supported languages — TypeScript, JavaScript, Python, Rust, Go, Java, C#, and C++ — are parsed via tree-sitter WASM grammars (real syntax trees compiled to WebAssembly, in-process, zero native dependencies). A scope-tracking structural parser is kept as a fallback when WASM grammars are unavailable. No external AST server required.
LLM-Powered Deep Analysis (Prompts) — The server exposes MCP prompts (e.g., judge-data-security, judge-cybersecurity) that provide each judge's expert persona as a system prompt. When used by an LLM-based client (Copilot, Claude, Cursor, etc.), the host LLM performs deeper, context-aware probabilistic analysis beyond what static patterns can detect. This is where the systemPrompt on each judge comes alive — Judges itself makes no LLM calls, but it provides the expert criteria so your AI assistant can act as 45 specialized reviewers.

Composable by Design

Judges Panel is a dual-layer review system: instant deterministic tools (offline, no API keys) for pattern and AST analysis, plus 45 expert-persona MCP prompts that unlock LLM-powered deep analysis when connected to an AI client. It does not try to be a CVE scanner or a linter. Those capabilities belong in dedicated MCP servers that an AI agent can orchestrate alongside Judges.

Built-in AST Analysis

Unlike earlier versions that recommended a separate AST MCP server, Judges Panel now includes real AST-based structural analysis out of the box:

TypeScript, JavaScript, Python, Rust, Go, Java, C#, C++ — All parsed with a unified tree-sitter WASM engine for full syntax-tree analysis (functions, complexity, nesting, dead code, type safety). Falls back to a scope-tracking structural parser when WASM grammars are unavailable

The Code Structure judge (STRUCT-*) uses these parsers to accurately measure:

Rule	Metric	Threshold
`STRUCT-001`	Cyclomatic complexity	> 10 per function (high)
`STRUCT-002`	Nesting depth	> 4 levels (medium)
`STRUCT-003`	Function length	> 50 lines (medium)
`STRUCT-004`	Parameter count	> 5 parameters (medium)
`STRUCT-005`	Dead code	Unreachable statements (low)
`STRUCT-006`	Weak types	`any`, `dynamic`, `Object`, `interface{}`, `unsafe` (medium)
`STRUCT-007`	File complexity	> 40 total cyclomatic complexity (high)
`STRUCT-008`	Extreme complexity	> 20 per function (critical)
`STRUCT-009`	Extreme parameters	> 8 parameters (high)
`STRUCT-010`	Extreme function length	> 150 lines (high)

Layer	What It Does	Example Servers
Judges Panel	45-judge quality gate — security patterns, AST analysis, cost, scalability, a11y, compliance, sovereignty, ethics, dependency health, agent instruction governance, AI code safety, framework safety	This server
CVE / SBOM	Vulnerability scanning against live databases — known CVEs, license risks, supply chain	OSV, Snyk, Trivy, Grype MCP servers
Linting	Language-specific style and correctness rules	ESLint, Ruff, Clippy MCP servers
Runtime Profiling	Memory, CPU, latency measurement on running code	Custom profiling MCP servers

What This Means in Practice

When you ask your AI assistant "Is this code production-ready?", the agent can:

Judges Panel → Scan for hardcoded secrets, missing error handling, N+1 queries, accessibility gaps, compliance issues, plus analyze cyclomatic complexity, detect dead code, and flag deeply nested functions via AST
CVE Server → Check every dependency in package.json against known vulnerabilities
Linter Server → Enforce team style rules, catch language-specific gotchas

Each server returns structured findings. The AI synthesizes everything into a single, actionable review — no single server needs to do it all.

`plugins`	`string[]`	`[]`	Plugin module specifiers (npm packages or relative paths) that export custom judges
`judgeWeights`	`object`	`{}`	Weighted importance per judge for aggregated scoring (e.g. `{ "cybersecurity": 2.0 }`)
`failOnScoreBelow`	`number`	—	Minimum score (0–100) for the run to pass; complements `failOnFindings`
`regulatoryScope`	`string[]`	—	Regulatory frameworks in scope (e.g. `["GDPR", "PCI-DSS"]`). Findings citing ONLY out-of-scope frameworks are suppressed. Run `judges list --frameworks` for supported values.
`consensusThreshold`	`number`	—	Consensus suppression (0–1). If this fraction of judges report zero findings, minority findings are suppressed. Recommended: `0.7` for CI.
`escalationThreshold`	`number`	—	Confidence threshold (0–1) below which findings are flagged for human review
`overrides`	`array`	`[]`	Path-scoped config overrides (e.g. `[{ "files": "*/.test.ts", "disabledJudges": ["documentation"] }]`)
`customRules`	`array`	`[]`	User-defined regex-based rules for business logic validation

All evaluation tools (CLI and MCP) accept the same configuration fields via --config <path> or inline config parameter.

Advanced Features

Inline Suppressions

Suppress specific findings directly in source code using comment directives:

server.ts

const x = eval(input); // judges-ignore SEC-001
// judges-ignore-next-line CYBER-002
const y = dangerousOperation();
// judges-file-ignore DOC-*    ← suppress globally for this file

Supported comment styles: //, #, /* */. Supports comma-separated rule IDs and wildcards (*, SEC-*).

Auto-Fix Patches

Certain findings include machine-applicable patches in the patch field:

Pattern	Auto-Fix
`new Buffer(x)`	→ `Buffer.from(x)`
`http://` URLs (non-localhost)	→ `https://`
`Math.random()`	→ `crypto.randomUUID()`

Patches include oldText, newText, startLine, and endLine for automated application.

Cross-Evaluator Deduplication

When multiple judges flag the same issue (e.g., both Data Security and Cybersecurity detect SQL injection on line 15), findings are automatically deduplicated. The highest-severity finding wins, and the description is annotated with cross-references (e.g., "Also identified by: CYBER-003").

Human Focus Guide

Every tribunal evaluation includes a humanFocusGuide that categorizes findings into three buckets for human reviewers:

Bucket	Description	When to use
✅ Trust	High-confidence (≥80%), evidence-backed findings with AST/taint confirmation	Act directly — these have strong automated evidence
🔍 Verify	Lower-confidence or absence-based findings	Use your judgment — the issue may exist elsewhere in the project
🔦 Blind Spots	Areas automated analysis cannot evaluate	Focus your manual review time here

Blind spots are detected from code characteristics: complex branching logic, external service calls, financial calculations, PII handling, state machines, and complex regex. The guide appears in CLI text/markdown output, JSON/SARIF output, and GitHub Action step summaries.

Regulatory Scope

Configure which regulatory frameworks apply to your project in .judgesrc:

config.json

{ "regulatoryScope": ["GDPR", "PCI-DSS", "SOC2"] }

Findings that cite ONLY out-of-scope frameworks are suppressed. Findings with no regulatory reference (general code quality) are always kept. Run judges list --frameworks to see all 17 supported frameworks (GDPR, CCPA, HIPAA, PCI-DSS, SOC2, SOX, COPPA, FedRAMP, NIST, ISO27001, ePrivacy, DORA, NIS2, EU-AI-Act, and more).

Self-Teaching Amendments

The LLM benchmark system auto-generates precision amendments for judges with high false-positive rates. Amendments are data-driven corrections injected into prompts that improve accuracy over successive benchmark runs.

The self-teaching loop:

Run benchmark → analyzer identifies judges below 70% precision
Generates targeted amendments (e.g., "Judge ERR: do not flag clean Express code with framework error middleware")
Next benchmark run loads amendments → precision improves
Run judges codify-amendments to bake amendments permanently into the distributed package

Taint Flow Analysis

The engine performs inter-procedural taint tracking to trace data from user-controlled sources (e.g., req.body, process.env) through transformations to security-sensitive sinks (e.g., eval(), exec(), SQL queries). Taint flows are used to boost confidence on true-positive findings and suppress false positives where sanitization is detected.

Positive Signal Detection

Code that demonstrates good practices receives score bonuses (capped at +15):

Signal	Bonus
Parameterized queries	+3
Security headers (helmet)	+3
Auth middleware (passport, etc.)	+3
Proper error handling	+2
Input validation libs (zod, joi, etc.)	+2
Rate limiting	+2
Structured logging (pino, winston)	+2
CORS configuration	+1
Strict mode / strictNullChecks	+1
Test patterns (describe/it/expect)	+1

Framework-Aware Rules

Judges include framework-specific detection for Express, Django, Flask, FastAPI, Spring, ASP.NET, Rails, and more. Framework middleware (e.g., helmet(), express-rate-limit, passport.authenticate()) is recognized as mitigation, reducing false positives.

Cross-File Import Resolution

In project-level analysis, imports are resolved across files. If one file imports a security middleware module from another file in the project, findings about missing security controls are automatically adjusted with reduced confidence.

Scoring

Each judge scores the code from 0 to 100:

Severity	Score Deduction
Critical	−30 points
High	−18 points
Medium	−10 points
Low	−5 points
Info	−2 points

Verdict logic:

FAIL — Any critical finding, or score < 60
WARNING — Any high finding, any medium finding, or score < 80
PASS — Score ≥ 80 with no critical, high, or medium findings

The overall tribunal score is the average of all 45 judges. The overall verdict fails if any judge fails.

Daily Popular Repo Automation

This repo includes a scheduled workflow at .github/workflows/daily-popular-repo-autofix.yml that:

selects up to 10 repositories per day from a default pool of 100+ popular repos (or a manually supplied target),
runs the full Judges evaluation across supported source languages,
applies only conservative, single-line remediations that reduce matching finding counts,
opens up to 5 PRs per repository with attribution to both Judges and the target repository,
skips repositories unless they are public and PR creation is possible with existing GitHub auth (no additional auth flow).
enforces hard runtime caps of 10 repositories/day and 5 PRs/repository.

Each run writes daily-autofix-summary.json (or SUMMARY_PATH) with per-repository telemetry, including:

runAggregate — compact run-level totals and cross-repo top prioritized rules,
runAggregate.totalCandidatesDiscovered and runAggregate.totalCandidatesAfterLocationDedupe — signal how much overlap was removed before attempting fixes,
runAggregate.totalCandidatesAfterPriorityThreshold — candidates that remain after applying minimum priority score,
runAggregate.dedupeReductionPercent — percent reduction from location dedupe for quick runtime-efficiency tracking,
runAggregate.priorityThresholdReductionPercent — percent reduction from minimum-priority filtering after dedupe,
priorityRulePrefixesUsed — dangerous rule prefixes used during prioritization,
minPriorityScoreUsed — minimum candidatePriorityScore applied for candidate inclusion,
candidatesDiscovered, candidatesAfterLocationDedupe, and candidatesAfterPriorityThreshold — per-repo candidate counts after each filter stage,
topPrioritizedRuleCounts — most common rule IDs among ranked candidates,
topPrioritizedCandidates — top ranked candidate samples (rule, severity, confidence, file, line, priority score).

Optional runtime control:

AUTOFIX_MIN_PRIORITY_SCORE — minimum candidate priority score required after dedupe (default: 0, disabled).

Required secret:

JUDGES_AUTOFIX_GH_TOKEN — GitHub token with permission to fork/push/create PRs for target repositories.

Manual run:

bash

gh workflow run "Judges Daily Full-Run Autofix PRs" -f targetRepoUrl=https://github.com/owner/repo

Programmatic API

server.ts

import {
  evaluateCode,
  evaluateProject,
  evaluateCodeSingleJudge,
  getJudge,
  JUDGES,
  findingsToSarif,
} from "@kevinrabun/judges/api";

// Full tribunal evaluation
const verdict = evaluateCode("const x = eval(input);", "typescript");
console.log(verdict.overallScore, verdict.overallVerdict);

// Single judge
const result = evaluateCodeSingleJudge("cybersecurity", code, "typescript");

// SARIF output for CI integration
const sarif = findingsToSarif(verdict.evaluations.flatMap(e => e.findings));

SARIF Output

Convert findings to SARIF 2.1.0 for GitHub Code Scanning, Azure DevOps, and other CI/CD tools:

server.ts

import { findingsToSarif, evaluationToSarif, verdictToSarif } from "@kevinrabun/judges/sarif";

const sarif = verdictToSarif(verdict, "src/app.ts");
fs.writeFileSync("results.sarif", JSON.stringify(sarif, null, 2));

Custom Error Types

All thrown errors extend JudgesError with a machine-readable code property:

Error Class	Code	When

const verdict = evaluateCode("const password = 'ProdSecret';", "typescript");
console.log(verdict.overallVerdict, verdict.overallScore);

MCP server

The MCP server runs on stdio and is started by your MCP client (VS Code, Claude Desktop, etc.). Configure it in your MCP settings (e.g. mcp.json):

config.json

{
  "servers": {
    "judges": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@kevinrabun/judges"]
    }
  }
}

Or run the server directly:

Terminal

npx @kevinrabun/judges
# Starts the MCP server on stdio

Config file: .judgesrc.json (supports ${ENV_VAR} substitution via expandEnvPlaceholders). See Configuration.

GitHub App (self-hosted webhook)

Run a zero-config PR reviewer as a GitHub App:

bash

# Run the webhook server locally
judges app serve --port 4567

Required env vars:

JUDGES_APP_ID – GitHub App ID
JUDGES_PRIVATE_KEY or JUDGES_PRIVATE_KEY_PATH – PEM private key
JUDGES_WEBHOOK_SECRET – signature verification secret

Optional:

JUDGES_MIN_SEVERITY (default: medium)
JUDGES_MAX_COMMENTS (default: 25)
JUDGES_TEST_DRY_RUN=1 to avoid live network calls during tests

For local testing, you can expose http://localhost:4567/webhook via ngrok http 4567 and configure the GitHub App webhook URL accordingly.

Use in GitHub Actions

Add Judges to your CI pipeline with zero configuration:

yaml

# .github/workflows/judges.yml
name: Judges Code Review
on: [pull_request]

jobs:
  judges:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      security-events: write  # only if using upload-sarif
    steps:
      - uses: actions/checkout@v4
      - uses: KevinRabun/judges@main
        with:
          path: src/api.ts        # file or directory
          format: text             # text | json | sarif | markdown
          upload-sarif: true       # upload to GitHub Code Scanning
          fail-on-findings: true   # fail CI on critical/high findings

Outputs available for downstream steps: verdict, score, findings, critical, high, sarif-file.

Use with Docker (no Node.js required)

bash

# Build the image
docker build -t judges .

# Evaluate a local file
docker run --rm -v $(pwd):/code judges eval --file /code/app.ts

# Pipe from stdin
cat api.py | docker run --rm -i judges eval --language python

# List judges
docker run --rm judges list

Or use as an MCP server

1. Install and Build

bash

git clone https://github.com/KevinRabun/judges.git
cd judges
npm install
npm run build

2. Try the Demo

Run the included demo to see all 45 judges evaluate a purposely flawed API server:

Terminal

npm run demo

The demo now also includes an App Builder Workflow (3-step) section. In a single run, you get both tribunal output and workflow output:

3. Run the Tests

Terminal

npm test

Runs automated tests covering all judges, AST parsers, markdown formatters, and edge cases.

4. Connect to Your Editor

VS Code (recommended — zero config)

Install the Judges Panel extension from the Marketplace. It provides:

Inline diagnostics & quick-fixes on every file save
@judges chat participant — type @judges in Copilot Chat, or just ask for a "judges panel review" and Copilot routes automatically
Auto-configured MCP server — all 45 expert-persona prompts available to Copilot with zero setup

bash

code --install-extension kevinrabun.judges-panel

VS Code — manual MCP config

If you prefer explicit workspace config (or want teammates without the extension to benefit), create .vscode/mcp.json:

config.json

{
  "servers": {
    "judges": {
      "command": "npx",
      "args": ["-y", "@kevinrabun/judges"]
    }
  }
}

Claude Desktop

Add to claude_desktop_config.json:

config.json

{
  "mcpServers": {
    "judges": {
      "command": "npx",
      "args": ["-y", "@kevinrabun/judges"]
    }
  }
}

Cursor / other MCP clients

Use the same npx command for any MCP-compatible client:

config.json

{
  "command": "npx",
  "args": ["-y", "@kevinrabun/judges"]
}

5. Use Judges in GitHub Copilot PR Reviews

Yes — users can include Judges as part of GitHub-based review workflows, with one important caveat:

The hosted copilot-pull-request-reviewer on GitHub does not currently let you directly attach arbitrary local MCP servers the same way VS Code does.
The practical pattern is to run Judges in CI on each PR, publish a report/check, and have Copilot + human reviewers use that output during review.

Option A (recommended): PR workflow check + report artifact

Create .github/workflows/judges-pr-review.yml:

server.ts

name: Judges PR Review

on:
  pull_request:
    types: [opened, synchronize, reopened]

jobs:
  judges:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      pull-requests: write

    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Setup Node
        uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: npm

      - name: Install
        run: npm ci

      - name: Generate Judges report
        run: |
          npx tsx -e "import { generateRepoReportFromLocalPath } from './src/reports/public-repo-report.ts';
          const result = generateRepoReportFromLocalPath({
            repoPath: process.cwd(),
            outputPath: 'judges-pr-report.md',
            maxFiles: 600,
            maxFindingsInReport: 150,
          });
          console.log('Overall:', result.overallVerdict, result.averageScore);"

      - name: Upload report artifact
        uses: actions/upload-artifact@v4
        with:
          name: judges-pr-report
          path: judges-pr-report.md

This gives every PR a reproducible Judges output your team (and Copilot) can reference.

Option B: Add Copilot custom instructions in-repo

Add .github/instructions/judges.instructions.md with guidance such as:

markdown

When reviewing pull requests:
1. Read the latest Judges report artifact/check output first.
2. Prioritize CRITICAL and HIGH findings in remediation guidance.
3. If findings conflict, defer to security/compliance-related Judges.
4. Include rule IDs (e.g., DATA-001, CYBER-004) in suggested fixes.

This helps keep Copilot feedback aligned with Judges findings.

CLI Reference

All commands support --help for usage details.

How It Works

The tribunal operates in three layers:

Pattern-Based Analysis — All tools (evaluate_code, evaluate_code_single_judge, evaluate_project, evaluate_diff) perform heuristic analysis using regex pattern matching to catch common anti-patterns. This layer is instant, deterministic, and runs entirely offline with zero external API calls.
AST-Based Structural Analysis — The Code Structure judge (STRUCT-* rules) uses real Abstract Syntax Tree parsing to measure cyclomatic complexity, nesting depth, function length, parameter count, dead code, and type safety with precision that regex cannot achieve. All supported languages — TypeScript, JavaScript, Python, Rust, Go, Java, C#, and C++ — are parsed via tree-sitter WASM grammars (real syntax trees compiled to WebAssembly, in-process, zero native dependencies). A scope-tracking structural parser is kept as a fallback when WASM grammars are unavailable. No external AST server required.
LLM-Powered Deep Analysis (Prompts) — The server exposes MCP prompts (e.g., judge-data-security, judge-cybersecurity) that provide each judge's expert persona as a system prompt. When used by an LLM-based client (Copilot, Claude, Cursor, etc.), the host LLM performs deeper, context-aware probabilistic analysis beyond what static patterns can detect. This is where the systemPrompt on each judge comes alive — Judges itself makes no LLM calls, but it provides the expert criteria so your AI assistant can act as 45 specialized reviewers.

Composable by Design

Built-in AST Analysis

Unlike earlier versions that recommended a separate AST MCP server, Judges Panel now includes real AST-based structural analysis out of the box:

TypeScript, JavaScript, Python, Rust, Go, Java, C#, C++ — All parsed with a unified tree-sitter WASM engine for full syntax-tree analysis (functions, complexity, nesting, dead code, type safety). Falls back to a scope-tracking structural parser when WASM grammars are unavailable

The Code Structure judge (STRUCT-*) uses these parsers to accurately measure:

Rule	Metric	Threshold
`STRUCT-001`	Cyclomatic complexity	> 10 per function (high)
`STRUCT-002`	Nesting depth	> 4 levels (medium)
`STRUCT-003`	Function length	> 50 lines (medium)
`STRUCT-004`	Parameter count	> 5 parameters (medium)
`STRUCT-005`	Dead code	Unreachable statements (low)
`STRUCT-006`	Weak types	`any`, `dynamic`, `Object`, `interface{}`, `unsafe` (medium)
`STRUCT-007`	File complexity	> 40 total cyclomatic complexity (high)
`STRUCT-008`	Extreme complexity	> 20 per function (critical)
`STRUCT-009`	Extreme parameters	> 8 parameters (high)
`STRUCT-010`	Extreme function length	> 150 lines (high)

Layer	What It Does	Example Servers
Judges Panel	45-judge quality gate — security patterns, AST analysis, cost, scalability, a11y, compliance, sovereignty, ethics, dependency health, agent instruction governance, AI code safety, framework safety	This server
CVE / SBOM	Vulnerability scanning against live databases — known CVEs, license risks, supply chain	OSV, Snyk, Trivy, Grype MCP servers
Linting	Language-specific style and correctness rules	ESLint, Ruff, Clippy MCP servers
Runtime Profiling	Memory, CPU, latency measurement on running code	Custom profiling MCP servers

What This Means in Practice

When you ask your AI assistant "Is this code production-ready?", the agent can:

Judges Panel → Scan for hardcoded secrets, missing error handling, N+1 queries, accessibility gaps, compliance issues, plus analyze cyclomatic complexity, detect dead code, and flag deeply nested functions via AST
CVE Server → Check every dependency in package.json against known vulnerabilities
Linter Server → Enforce team style rules, catch language-specific gotchas

Each server returns structured findings. The AI synthesizes everything into a single, actionable review — no single server needs to do it all.

Advanced Features

Inline Suppressions

Suppress specific findings directly in source code using comment directives:

server.ts

const x = eval(input); // judges-ignore SEC-001
// judges-ignore-next-line CYBER-002
const y = dangerousOperation();
// judges-file-ignore DOC-*    ← suppress globally for this file

Supported comment styles: //, #, /* */. Supports comma-separated rule IDs and wildcards (*, SEC-*).

Auto-Fix Patches

Certain findings include machine-applicable patches in the patch field:

Pattern	Auto-Fix
`new Buffer(x)`	→ `Buffer.from(x)`
`http://` URLs (non-localhost)	→ `https://`
`Math.random()`	→ `crypto.randomUUID()`

Patches include oldText, newText, startLine, and endLine for automated application.

Cross-Evaluator Deduplication

Human Focus Guide

Every tribunal evaluation includes a humanFocusGuide that categorizes findings into three buckets for human reviewers:

Bucket	Description	When to use
✅ Trust	High-confidence (≥80%), evidence-backed findings with AST/taint confirmation	Act directly — these have strong automated evidence
🔍 Verify	Lower-confidence or absence-based findings	Use your judgment — the issue may exist elsewhere in the project
🔦 Blind Spots	Areas automated analysis cannot evaluate	Focus your manual review time here

Regulatory Scope

Configure which regulatory frameworks apply to your project in .judgesrc:

config.json

{ "regulatoryScope": ["GDPR", "PCI-DSS", "SOC2"] }

Self-Teaching Amendments

The self-teaching loop:

Run benchmark → analyzer identifies judges below 70% precision
Generates targeted amendments (e.g., "Judge ERR: do not flag clean Express code with framework error middleware")
Next benchmark run loads amendments → precision improves
Run judges codify-amendments to bake amendments permanently into the distributed package

Taint Flow Analysis

Positive Signal Detection

Code that demonstrates good practices receives score bonuses (capped at +15):

Signal	Bonus
Parameterized queries	+3
Security headers (helmet)	+3
Auth middleware (passport, etc.)	+3
Proper error handling	+2
Input validation libs (zod, joi, etc.)	+2
Rate limiting	+2
Structured logging (pino, winston)	+2
CORS configuration	+1
Strict mode / strictNullChecks	+1
Test patterns (describe/it/expect)	+1

Framework-Aware Rules

Cross-File Import Resolution

Scoring

Each judge scores the code from 0 to 100:

Severity	Score Deduction
Critical	−30 points
High	−18 points
Medium	−10 points
Low	−5 points
Info	−2 points

Verdict logic:

FAIL — Any critical finding, or score < 60
WARNING — Any high finding, any medium finding, or score < 80
PASS — Score ≥ 80 with no critical, high, or medium findings

The overall tribunal score is the average of all 45 judges. The overall verdict fails if any judge fails.

Daily Popular Repo Automation

This repo includes a scheduled workflow at .github/workflows/daily-popular-repo-autofix.yml that:

selects up to 10 repositories per day from a default pool of 100+ popular repos (or a manually supplied target),
runs the full Judges evaluation across supported source languages,
applies only conservative, single-line remediations that reduce matching finding counts,
opens up to 5 PRs per repository with attribution to both Judges and the target repository,
skips repositories unless they are public and PR creation is possible with existing GitHub auth (no additional auth flow).
enforces hard runtime caps of 10 repositories/day and 5 PRs/repository.

Each run writes daily-autofix-summary.json (or SUMMARY_PATH) with per-repository telemetry, including:

runAggregate — compact run-level totals and cross-repo top prioritized rules,
runAggregate.totalCandidatesDiscovered and runAggregate.totalCandidatesAfterLocationDedupe — signal how much overlap was removed before attempting fixes,
runAggregate.totalCandidatesAfterPriorityThreshold — candidates that remain after applying minimum priority score,
runAggregate.dedupeReductionPercent — percent reduction from location dedupe for quick runtime-efficiency tracking,
runAggregate.priorityThresholdReductionPercent — percent reduction from minimum-priority filtering after dedupe,
priorityRulePrefixesUsed — dangerous rule prefixes used during prioritization,
minPriorityScoreUsed — minimum candidatePriorityScore applied for candidate inclusion,
candidatesDiscovered, candidatesAfterLocationDedupe, and candidatesAfterPriorityThreshold — per-repo candidate counts after each filter stage,
topPrioritizedRuleCounts — most common rule IDs among ranked candidates,
topPrioritizedCandidates — top ranked candidate samples (rule, severity, confidence, file, line, priority score).

Optional runtime control:

AUTOFIX_MIN_PRIORITY_SCORE — minimum candidate priority score required after dedupe (default: 0, disabled).

Required secret:

JUDGES_AUTOFIX_GH_TOKEN — GitHub token with permission to fork/push/create PRs for target repositories.

Manual run:

bash

gh workflow run "Judges Daily Full-Run Autofix PRs" -f targetRepoUrl=https://github.com/owner/repo

Programmatic API

Judges can be consumed as a library (not just via MCP). Import from @kevinrabun/judges/api:

server.ts

import {
  evaluateCode,
  evaluateProject,
  evaluateCodeSingleJudge,
  getJudge,
  JUDGES,
  findingsToSarif,
} from "@kevinrabun/judges/api";

// Full tribunal evaluation
const verdict = evaluateCode("const x = eval(input);", "typescript");
console.log(verdict.overallScore, verdict.overallVerdict);

// Single judge
const result = evaluateCodeSingleJudge("cybersecurity", code, "typescript");

// SARIF output for CI integration
const sarif = findingsToSarif(verdict.evaluations.flatMap(e => e.findings));

SARIF Output

Convert findings to SARIF 2.1.0 for GitHub Code Scanning, Azure DevOps, and other CI/CD tools:

server.ts

import { findingsToSarif, evaluationToSarif, verdictToSarif } from "@kevinrabun/judges/sarif";

const sarif = verdictToSarif(verdict, "src/app.ts");
fs.writeFileSync("results.sarif", JSON.stringify(sarif, null, 2));

Custom Error Types

All thrown errors extend JudgesError with a machine-readable code property:

Error Class	Code	When
`ConfigError`	`JUDGES_CONFIG_INVALID`	Malformed `.judgesrc` or invalid inline config
`EvaluationError`	`JUDGES_EVALUATION_FAILED`	Unknown judge, analyzer crash
`ParseError`	`JUDGES_PARSE_FAILED`	Unparseable source code or input data
