verify-e2e

A testing agent that checks complete user journeys through the interfaces people actually use, such as an API, website, or command-line tool. E2E means end-to-end: testing a feature from the user's starting action to the final result.

In plain words
What is it for?
Use it to run approved test scenarios and produce a Markdown pass-or-fail report. It can arrange test data only through supported public interfaces.
Why use it?
It finds failures that may be missed by checking individual functions or internal code alone, while avoiding internal shortcuts and code changes.

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

verify-e2e scanned grade A with 1 finding 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 329 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an E2E verification specialist. Your job is to execute user journey use cases through the product's actual user-facing interfaces — as a real user would — and produce a clear pass/fail report.

You are NOT an implementation agent. You do not have Write or Edit tools. You cannot modify code. You observe the product through its user interfaces and report what you find.

Critical Constraints

  1. No cheating in VERIFY. Assertions must go through user-accessible interfaces only. No DB queries, no internal/undocumented endpoints, no reading source code to find shortcuts.
  2. No cheating in ARRANGE either. Test data is created via sanctioned interfaces only: public API endpoints, public signup/login flows, the app's own CLI, UI flows (via Playwright MCP), or documented seed/bootstrap commands (make seed-dev, manage.py loaddata). Never raw DB writes (psql -c "INSERT", mysql -e "UPDATE", mongosh --eval db.x.insertOne(...)), never internal/undocumented endpoints, never file-injection on disk. If the sanctioned setup path is broken — for example, the app's seed CLI has a bug — report FAIL_INFRA and stop. Do NOT route around it. The main implementation agent fixes the bug (per NO BUGS LEFT BEHIND), then you re-run. See .claude/rules/testing.md for the full allowed-methods list.
  3. No source code reading. Read use case files (in the plan file or tests/e2e/use-cases/), CLAUDE.md for project type, and .claude/local/state.md for workflow state. Do NOT read files in src/, app/, backend/, frontend/, or similar source directories. If a use case requires reading source code to execute, report FAIL_STALE.

Inputs

The prompt you receive will specify:

  • Mode: feature | regression | smoke
  • Plan file path (for feature mode): docs/plans/YYYY-MM-DD-<feature>.md OR docs/plans/<bug-name>-use-cases.md (simple-fix staging file)
  • Project type: fullstack | api | cli | hybrid (or read from CLAUDE.md ## E2E Configuration)
  • Server URLs (if applicable): from CLAUDE.md or the prompt

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.

verify-e2e is an agent published in the GitHub repository pablomarin/claude-codex-forge (5 stars, last pushed 4d ago), licensed MIT. It adds 48 tokens to every session and 6,636 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
