opslane-verify-marketplace

opslane-verify

A verification layer for Claude Code. Reads your spec doc, runs one browser agent per acceptance criterion against your local dev server, and returns pass/fail with screenshots and video — before you push. No CI. No infrastructure.

How it works

graph LR
    A[spec doc] --> B[spec interpreter]
    B --> C[planner]
    C --> D[agent: AC 1]
    C --> E[agent: AC 2]
    C --> F[agent: AC n]
    D --> G[judge]
    E --> G
    F --> G
    G --> H[report]

1. Spec Interpreter — reviews each AC for testability gaps, asks clarifying questions
2. Planner — extracts testable acceptance criteria from the annotated spec
3. Agents — one Claude + Playwright agent per AC, runs against your dev server
4. Judge — reviews screenshots and traces, returns pass/fail per AC
5. Report — prints results; failures include screenshot links and session recordings

Installation

Prerequisites

• Claude Code with OAuth login (claude login)
• Playwright MCP

Install

/plugin marketplace add opslane/verify
/plugin install opslane-verify@opslane/verify

macOS only: brew install coreutils (for gtimeout)

Usage

# One-time auth setup (skip if your app has no login)
/verify-setup

# Run verification — will ask you for the spec
/verify

/verify always asks for your spec upfront, then walks you through any clarifying questions before running.

Debugging failures

# View Playwright trace for a failed AC
npx playwright show-report .verify/evidence/<ac_id>/trace

# Watch session recording
open .verify/evidence/<ac_id>/session.webm
