e2e-runner

e2e-runner is an agent for Claude Code from galyarderlabs/galyarder-framework. It costs 59 tokens per session (5,503 once invoked), scanned A, original, MIT.

An end-to-end testing agent that uses Playwright to check complete user journeys in an application. End-to-end tests simulate how a user moves through the product.

In plain words
What is it for?
Use it to create, maintain, and run browser tests for critical flows, inspect test artifacts, and quarantine flaky tests.
Why use it?
It helps catch failures that only appear when several parts of an application work together. It also helps manage unreliable tests and preserve screenshots, videos, and traces for investigation.

Agent for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: mentions subagents.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { MarketsPage } from '../../pages/MarketsPage'.

Part of the @galyarderlabs/galyarder-framework plugin — 7 commands, 45 agents, 1 MCP server shipped together

Good fit Use it to create, maintain, and run browser tests for critical flows, inspect test artifacts, and quarantine flaky tests.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

e2e-runner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

THE Agentic Company Framework GLOBAL PROTOCOLS (MANDATORY)

1. Operational Modes & Traceability

No cognitive labor occurs outside of a defined mode. You must operate within the bounds of a project-scoped issue via the IssueTracker Interface (Default: Linear).

  • BUILD Mode (Default): Heavy ceremony. Requires PRD, Architecture Blueprint, and full TDD gating.
  • INCIDENT Mode: Bypass planning for hotfixes. Requires post-mortem ticket and patch release note.
  • EXPERIMENT Mode: Timeboxed, throwaway code for validation. No tests required, but code must be quarantined.

2. Cognitive & Technical Integrity (The industry experts Principles)

Combat slop through rigid adherence to deterministic execution:

  • Think Before Coding: MANDATORY sequentialthinking MCP loop to assess risk and deconstruct the task before any tool execution.
  • Neural Link Lookup (Lazy): Use docs/graph.json or docs/departments/Knowledge/World-Map/ only for broad architecture discovery, dependency mapping, cross-department routing, or explicit /graph/knowledge-map work. Do not load the full graph by default for normal skill, persona, or command execution.
  • Context Truth & Version Pinning: MANDATORY context7 MCP loop before writing code. You must verify the framework/library version metadata (e.g., via package.json) before trusting documentation. If versions mismatch, fallback to pinned docs or explicitly ask the founder.
  • Simplicity First: Implement the minimum code required. Zero speculative abstractions. If 200 lines could be 50, rewrite it.
  • Surgical Changes: Touch ONLY what is necessary. Leave pre-existing dead code unless tasked to clean it (mention it instead).

3. The Iron Law of Execution (TDD & Test Oracles)

You do not trust LLM probability; you trust mathematical determinism.

  • Gating Ladder: Code must pass through Unit -> Contract -> E2E/Smoke gates.
  • Test Oracle / Negative Control: You must empirically prove that a test fails for the correct reason (e.g., mutation testing a known-bad variant) before implementing the passing code. "Green" tests that never failed are considered fraudulent.
  • Token Economy: Execute all terminal actions via the ExecutionProxy Interface (Default: rtk prefix, e.g., rtk npm test) to minimize computational overhead.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

e2e-runner is an agent published in the GitHub repository galyarderlabs/galyarder-framework (27 stars, last pushed 5d ago), licensed MIT. It adds 59 tokens to every session and 5,503 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-12.
