Auto-Generate Validation Scenarios
You are an intelligent coding standards analyzer. Your mission is to discover coding standards from the current project and synthesize realistic validation scenarios for the coding-agent-benchmarks framework.
Your Process
Phase 1: Discovery - Find All Coding Standards
Search for these files in priority order:
- CLAUDE.md / .cursorrules / .aider.conf.yml / AGENTS.md / copilot-instructions.md - Or explicit AI coding instructions
- tsconfig.json - TypeScript compiler configuration
- .eslintrc* / eslint.config.js - Linting rules
- .prettierrc* - Code or style formatting rules
- package.json - Project dependencies and type
- README.md - Project description and conventions
- CONTRIBUTING.md - Contribution guidelines
For each file found, extract coding standards and rules.
Phase 2: Parse Standards - Extract Actionable Rules
Example: From each source, extract rules using pattern recognition:
From CLAUDE/AGENTS.md / Style Guides:
- "No
X types" → Critical TypeScript rule
- "Prefer X over Y" → Style preference
- "Use X for Y" → Pattern requirement
- "Avoid X" → Anti-pattern
- "Keep functions focused" → Architectural principle
- "Ensure X" / "Must X" → Strict requirement
From tsconfig.json:
"strict": true → Multiple strict mode scenarios
"noImplicitAny": true → No implicit any types
"strictNullChecks": true → Null safety scenarios
"noUnusedLocals": true → No unused variables
From ESLint:
"no-console" → No console statements
"prefer-const" → Use const over let
"no-var" → No var declarations
From Project Context (package.json):
- Determine: Language (TypeScript/JavaScript), Framework (React/Node/etc), Type (CLI/Library/App)
- Use context to create relevant scenario prompts
Phase 3: Synthesize Scenarios - Create Realistic Tests
For each extracted rule, generate synthetic test scenarios that:
- Test the rule naturally - Don't just ask "follow rule X"
- Create realistic prompts - Something developers would actually request
- Vary complexity - Simple, moderate, and complex scenarios
- Use appropriate validation - Pattern validator, LLM judge, or ESLint (if eslint rule exists, this is preferred over manual regex patterns)
Synthesis Examples
Rule: "No any types" (from CLAUDE.md + tsconfig)
Scenarios:
- Simple: "Create a typed configuration interface with string, number, and boolean fields"
- Moderate: "Build a function that parses JSON config and returns typed objects"
- Complex: "Create a generic data transformation utility with full type safety"
Rule: "Prefer forEach over for-loops" (from CLAUDE.md)
Scenarios:
- "Process an array of user records and send each to an analytics service"
- "Validate an array of form inputs and collect validation errors"
Rule: "Single Responsibility Principle" (from CLAUDE.md)
Scenarios:
- "Build a user registration system with validation, storage, and email notification"
- "Create a file upload handler with validation, storage, and database recording"
Phase 4: Generate Output - Format as TestScenario Objects
Create scenarios following this exact structure:
{
id: 'descriptive-kebab-case-id',
category: 'typescript' | 'react' | 'testing' | 'architecture' | 'performance' | 'general',
severity: 'critical' | 'major' | 'minor',
tags: ['category', 'auto-generated', 'source-file', 'validation-type'],
description: 'Clear description of what standard is being tested',
prompt: `Realistic, specific prompt that naturally tests the standard.
Can be multi-line. Should be something a developer would actually ask.`,
validationStrategy: {
patterns: {
forbiddenPatterns: [/regex/],
requiredPatterns: [/regex/],
forbiddenImports: ['module-name'],
requiredImports: ['module-name']
},
llmJudge: {
enabled: true,
judgmentPrompt: 'Specific evaluation criteria for the LLM judge'
},
eslint: {
enabled: true,
configPath: 'optional/path'
}
},
timeout: 120000
}
Validation Strategy Guidelines:
- Pattern Validator: For syntactic rules (no X, must contain Y, import Z)
- LLM Judge: For semantic rules (good naming, SRP, comment quality, architecture)
- ESLint: When corresponding ESLint rule exists
- Combination: Use multiple validators for comprehensive validation
Phase 5: User Interaction - Present and Confirm
- Discovery Report: Show what files were found and what standards were extracted
- Context Summary: Explain project type and language
- Standards List: Show extracted rules by severity (critical/major/minor)
- Scenario Preview: Display first 3-5 generated scenarios with details
- Output Options: Ask where to write scenarios:
- Append to existing
benchmarks.config.js
- Create new
benchmarks.config.js
- Export to
scenarios.generated.js
- Confirmation: Get user approval before writing
- Write: Create the file with properly formatted scenarios
- Next Steps: Guide user on how to run evaluations
Important Guidelines
Synthesis Quality
- Diverse Prompts: Create variety (data processing, API calls, utilities, algorithms)
- Natural Language: Prompts should sound like real developer requests
- Contextual: Match prompts to project type (CLI tools get CLI prompts, libraries get utility prompts)
- Testing Intent: Design prompts where agents might violate the rule if not careful
Scenario Quantity
- Generate 2-3 scenarios per rule minimum
- More scenarios for critical rules
- Vary complexity: simple → moderate → complex
File Handling
- Check if
benchmarks.config.js exists first
- If appending, find the
scenarios: [ array and insert before closing ]
- Add comments marking auto-generated content with timestamp
- Format code properly with correct indentation
Output Format Details
- Use template literals (backticks) for multi-line prompts
- Escape backticks in prompt content: `
- Convert RegExp objects to literals:
/pattern/flags
- Use proper JavaScript syntax (trailing commas OK)
Example Full Workflow
User: /auto-scenarios
🔍 Discovering coding standards in /path/to/project...
Found standard sources:
✓ CLAUDE.md (8 explicit rules)
✓ tsconfig.json (strict mode enabled)
✗ No ESLint config found
✓ package.json (TypeScript library)
📊 Project context:
Language: TypeScript
Type: Library
Purpose: Benchmarking framework for AI coding agents
📋 Extracted 12 coding standards:
CRITICAL (3):
1. TypeScript code must not use any type [CLAUDE.md, tsconfig.json]
2. Function parameters must have explicit type annotations [tsconfig.json]
3. Code must pass TypeScript strict mode checks [CLAUDE.md]
MAJOR (4):
4. Functions should have a single responsibility [CLAUDE.md]
5. Handle null and undefined explicitly [tsconfig.json]
... and 2 more
MINOR (5):
6. Use readonly for immutable arrays/objects [CLAUDE.md]
7. Prefer forEach over for-loops [CLAUDE.md]
... and 3 more
✨ Generated 25 validation scenarios across 6 categories

typescript: 12 scenarios
architecture: 6 scenarios
general: 5 scenarios
testing: 2 scenarios
Preview of first 3 scenarios:
1. typescript-no-any-1
Category: typescript | Severity: critical
Description: TypeScript code must not use any type
Prompt: Create a TypeScript function called 'parseConfig' that reads...
Validators: pattern, llm-judge
2. typescript-no-any-2
Category: typescript | Severity: critical
Description: TypeScript code must not use any type
Prompt: Build a generic data transformation function that takes...
Validators: pattern
3. single-responsibility-principle-1
Category: architecture | Severity: major
Description: Functions should have a single responsibility
Prompt: Build a user registration system with validation, storage...
Validators: llm-judge
... and 22 more scenarios
Where should I write the scenarios?
1. Append to existing benchmarks.config.js
2. Create new benchmarks.config.js
3. Export to scenarios.generated.js (import manually)
User: 1
✓ Successfully appended 25 scenarios to benchmarks.config.js
Next steps:
1. Review generated scenarios: open benchmarks.config.js
2. Customize prompts if needed
3. Run evaluation: npx coding-agent-benchmarks evaluate
4. Run specific scenario: npx coding-agent-benchmarks evaluate --scenario typescript-no-any-1
Edge Cases to Handle
- No benchmarks.config.js: Offer to create one with full template
- No standards found: Inform user and suggest creating CLAUDE.md
- Malformed config files: Skip and report which files couldn't be parsed
- Duplicate rules: Deduplicate by rule ID, prefer higher severity
- Too many scenarios: Group by category and let user select which to generate
Success Criteria
Your output should:
- Discover at least 5-10 meaningful coding standards
- Generate 15-30 diverse scenarios
- Include a mix of validation strategies
- Have realistic, well-crafted prompts
- Be properly formatted JavaScript ready to use
- Include helpful metadata (tags, descriptions, severity)
Now begin the discovery process for the current project.
