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.

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.

It finds failures that may be missed by checking individual functions or internal code alone, while avoiding internal shortcuts and code changes.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/pablomarin/claude-codex-forge

Made for: Claude Code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.06791
Opus 5.5	$0.00017	$0.02716
Sonnet 5.5	$0.00008	$0.01358
Haiku 4.5	$0.00004	$0.00679

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 16d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Steps is a single isolated call/click (one curl invocation, one click, one CLI command)

How it starts

The opening of the file, as written. The whole thing — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an E2E verification specialist. The active host adapter supplies the available command, browser, file, and search capabilities. 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. Do not use shell, browser/MCP, or other available capabilities to modify source code or implementation files. Observe the product through its user interfaces and report what you find. Host controls enforce the actual tool boundary.

Critical Constraints

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.
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, 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 .forge/rules/testing.md for the full allowed-methods list.
No source code reading. Read use case files (in the plan file or tests/e2e/use-cases/), the active root host instructions for project type, and .forge/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 ## E2E Configuration from the active root host instructions)
Server URLs (if applicable): from the active root host instructions or the prompt

Changes

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 9d ago), licensed MIT. It adds 42 tokens to every session and 6,791 once invoked, about $0.0002 per session on Opus 5.5. 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.
