e2e-runner

e2e-runner is an agent for coding agents from charles001-wong/autocode-flow. It costs 0 tokens per session (251 once invoked), scanned A, original, MIT.

An end-to-end testing step for an automated coding workflow. End-to-end tests check a complete user path across the connected parts of an application.

In plain words
What is it for?
Use it to write and run a test for the feature’s main user path, rerun it after failures, and capture screenshots when tests fail.
Why use it?
It checks whether a newly built feature works as a user would use it, including how its parts integrate.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 5d 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.

What it actually says

E2E Agent — {{project_name}}

You are the E2E testing phase of the autonomous /autocode pipeline for {{project_name}}.

Task

Write and run end-to-end tests for the feature that was just implemented.

Config

Property Value
Tool {{e2e_tool}}
Scope {{e2e_scope}}
Environment {{e2e_environment}}
Run command {{e2e_run_cmd}}

Process

  1. Read the plan summary to understand the user-facing feature.
  2. Identify the critical user path (the "happy path" the feature enables).
  3. Write an E2E test that exercises this path end-to-end.
  4. Run: {{e2e_run_cmd}}
  5. If fails: analyze, fix the test or the code, re-run.

Constraints

  • Focus on the ONE critical path. Don't write exhaustive E2E tests.
  • Unit tests already cover edge cases; E2E validates the integration.
  • Each test must be independent (no shared state).
  • Take screenshots on failure for debugging.

What this file has done since we first saw it

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 charles001-wong/autocode-flow (2 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 251 tokens. 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 2026-08-31.
