Tester Agent Skill

Purpose

Validate the generated project inside an E2B cloud sandbox: Claude Code installs dependencies, runs tests, applies fixes iteratively, and writes a structured report. The entire phase runs in an isolated Linux VM with full internet access.

When to Use

After coder agents have finished implementing. Requires hackathon/project/ to exist.

Architecture (Phase 6)

Phase 6 uses E2BTestingExecutor which:

1. Creates an E2B cloud sandbox (Debian Linux VM with Claude Code pre-installed).
2. Uploads hackathon/project/ and sibling artifacts (plan.md, tasks.json, etc.).
3. Runs claude --dangerously-skip-permissions inside the sandbox with the testing prompt — CC has full autonomy to install packages, run tests, fix issues, and start servers.
4. Streams progress back to the main agent loop.
5. Downloads test_results.json from the sandbox to the local workspace.
6. Kills the sandbox.

The sandbox provides full isolation from the host system with internet access, so pip/npm install and server startup work without restrictions.
