name: harshjudge description: AI-native E2E testing orchestration for Claude Code. Use when creating, running, or managing end-to-end test scenarios with visual evidence capture. Activates for tasks involving E2E tests, browser automation testing, test scenario creation, test execution with screenshots, or checking test status.

HarshJudge E2E Testing

AI-native E2E testing with MCP tools and visual evidence capture.

Core Principles

1. Evidence First: Screenshot before and after every action
2. Fail Fast: Stop on error, report with context
3. Complete Runs: Always call completeRun, even on failure
4. Step Isolation: Each step executes in its own spawned agent for token efficiency
5. Knowledge Accumulation: Learnings go to prd.md, not scenarios

Step-Based Execution

HarshJudge uses a step-based agent pattern for token-efficient test execution:

CopyMain Agent                    Step Agents (spawned per step)
    │
    ├─ startRun(scenarioSlug)
    │      ↓
    │  Returns: runId, steps[]
    │
    ├─► Spawn Agent: Step 01 ──────────────────────► Execute actions
    │      │                                              │
    │      │ ◄─────────────────────────────────── Return: { status, evidencePaths }
    │      │
    │   completeStep(runId, "01", status)
    │      │
    ├─► Spawn Agent: Step 02 ──────────────────────► Execute actions
    │      │                                              │
    │      │ ◄─────────────────────────────────── Return: { status, evidencePaths }
    │      │
    │   completeStep(runId, "02", status)
    │      │
    │   ... (repeat for each step)
    │
    └─ completeRun(runId, finalStatus)

Benefits:

• Each step agent has isolated context (no token accumulation)
• Large outputs (screenshots, logs) saved to files, not returned
• Main agent only receives concise summaries
• Automatic token optimization without manual management

Quick Reference

HarshJudge MCP Tools

Playwright MCP Tools

Step Agent Prompt Template

When spawning an agent for each step:

CopyExecute step {stepId} of scenario {scenarioSlug}:

## Step Content
{content from steps/{stepId}-{slug}.md}

## Project Context
Base URL: {from config.yaml}
Auth: {from prd.md if needed}

## Previous Step
Status: {pass|fail|first step}

## Your Task
1. Execute the actions using Playwright MCP tools
2. Use browser_snapshot before clicking to get element refs
3. Capture before/after screenshots using browser_take_screenshot
4. Record evidence using recordEvidence with step={stepNumber}

Return ONLY a JSON object:
{
  "status": "pass" | "fail",
  "evidencePaths": ["path1.png", "path2.png"],
  "error": null | "error message"
}

DO NOT return full evidence content. DO NOT explain your work.

Error Handling

On ANY error:

1. STOP - Do not proceed
2. Report - Tool, params, error, resolution
3. Check prd.md - Is this a known pattern?
4. Do NOT retry - Unless user instructs
