What it does

E2E Test is an agent skill from liaohch3/claude-tap. Run claude-tap end-to-end tests with pytest

Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering End-to-end testing and Unit testing. It works with pytest. The repository describes itself as: Intercept and inspect Coding Agent API traffic from Claude Code, Codex CLI, Gemini CLI, Cursor CLI, OpenCode, Kimi/Kimi Code, Pi, and Hermes in a local trace viewer. The licence is MIT.

When your agent uses it

  • Tasks that involve End-to-end testing
  • Tasks that involve Unit testing

Example prompts

  • “/e2e-test”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Read the output. Each test prints PASSED or FAILED.
  2. If tests fail, check

What it can do on your machine

Read from SKILL.md and the folder at commit 4cc867d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

E2E Test loads about 369 tokens when it runs. Until then it costs about 13 tokens; SKILL.md has 116 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~13
When it runs · the whole SKILL.md, loaded when a task matches
~369

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

claude-tap E2E Test

Run this skill after modifying core logic in claude-tap, especially:

  • Proxy handler / SSE reassembly (__init__.py)
  • TraceWriter (JSONL writing, flush behavior)
  • HTML viewer generation (viewer.html, _generate_html_viewer)
  • LiveViewerServer (SSE streaming)
  • Signal handling / graceful shutdown
  • Manual update command / trace cleanup

Steps

  1. Run the full test suite:
bash
uv run pytest tests/test_e2e.py -v --timeout=120

Or run a single test:

bash
uv run pytest tests/test_e2e.py::test_e2e -v           # Full E2E pipeline
uv run pytest tests/test_e2e.py::test_trace_cleanup -v  # Trace cleanup
uv run pytest tests/test_e2e.py::test_startup_does_not_contact_pypi -v  # No startup update network

  1. Read the output. Each test prints PASSED or FAILED.

  2. If tests fail, check:

    • test_e2e fails: Core proxy pipeline issue. Check proxy_handler, _handle_streaming, TraceWriter.write.
    • test_trace_cleanup fails: Manifest logic issue. Check _load_manifest, _cleanup_traces, _register_trace.
    • test_startup_does_not_contact_pypi fails: Startup made an unexpected update-related network request.
    • test_live_viewer_ fails*: Viewer HTML issues. Check viewer.html for preserveDetail chain, updateNavButtons.
    • Timeout: May be a network/port issue, not a claude-tap bug.
