What is e2e-testdino?

A follow-up tool for e2e, a test runner that drives software through user-like steps, after a test run finishes on another machine. It retrieves and compares CI results, traces, merged test shards, flaky-test history, quarantined tests, and verified fixes when supported by the run records.

It is for investigating failed e2e runs in CI, fetching remote traces, reviewing results across runs, combining sharded results, managing quarantined tests, and checking fixes.

It addresses the gap between a failed test in continuous integration and the evidence stored on the machine that ran it. It helps determine whether a failure is flaky and keeps follow-up work from depending on local trace files.

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	$0.00230	$0.02331
Opus 5.5	$0.00092	$0.00932
Sonnet 5.5	$0.00046	$0.00466
Haiku 4.5	$0.00023	$0.00233

Security

Grade B, and why

e2e-testdino scanned grade B 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 yesterday.

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.

Reads MCP configurationmediumAgent snooping

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

2. **Is the TestDino MCP server connected?** Call its `health` tool. It returns the `projectId` every other tool needs. Not connected: `claude mcp add testdino --env TESTDINO_PAT=<token> -- npx -y @testdino/mcp@latest` f

e2e With TestDino: After the Run

The e2e skill ends at the edge of the machine that ran the tests. This pack starts there.

8 guides for the part of an e2e suite that happens after npx e2e run exits: results from CI, evidence you can fetch from another machine, history across runs, merged shards, quarantine, verified fixes, and what agent steps cost over time.

Verified against e2e 0.23.0 and @testdino/e2e 1.1.0. Check the project with npm ls e2e @testdino/e2e.

Which Skill for Which Job

e2e ships its own skill, and it is the reference for everything the runner does. This pack never restates it.

The job	Read
Add e2e to a project, write or fix a test, `agent.*` steps, CLI flags, error codes, `e2e explore`, bug bash	The e2e skill: `npx e2e guide <topic>` prints the installed version. Topics: `setup`, `mcp`, `writing-tests`, `agent`, `running`, `debugging`, `explore`, `bug-bash`. Missing? `npx e2e init` or `npx skills add e2e-inc/e2e` installs it (docs of e2e 0.23.0 and older name the former org, `tester-army/e2e`)
The failing run is on this disk (`.e2e/results/<test>/trace.md` exists)	The e2e skill, topic `debugging`
The run happened somewhere else, or the answer needs more than one run	This pack
A Playwright suite (`playwright.config.ts`, `*.spec.ts`)	The other packs of this skill, starting at ../SKILL.md

Before You Start

Three checks decide which guides can work in this project:

Is the reporter in the config? Look for testdino() in the reporters of e2e.config.ts. If it is missing, start with results-and-artifacts.md.
Is the TestDino MCP server connected? Call its health tool. It returns the projectId every other tool needs. Not connected: claude mcp add testdino --env TESTDINO_PAT=<token> -- npx -y @testdino/mcp@latest for Claude Code, or the same command and env under mcpServers in .cursor/mcp.json. The token is a Personal Access Token from TestDino's User Settings. Ask the user before adding a server or a token.
Which versions? Live results, failure details, trace pages and re-runs need @testdino/e2e 1.1.0 or later. Trace pages, app logs and visual comparison need e2e 0.19.0 or later.

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
