e2e-analyze

e2e-analyze is a skill for Claude Code from parisgroup-ai/imersao-ia-setup. It costs 46 tokens per session (1,236 once invoked), scanned A, original, MIT.

A skill for investigating end-to-end test failures by rebuilding the failure timeline, connecting errors to code, and checking relevant history.

In plain words
What is it for?
Use it after an end-to-end test run to analyze the last run or a named test, including its actions, page state, expected route, and related code.
Why use it?
It turns scattered test logs, screenshots, and errors into a structured explanation of what failed and why.

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-analyze 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 11d 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.

e2e-analyze - Failure Analysis

Analyze E2E failures with rich context: timeline, code correlation, and history.

Usage

/e2e-analyze                # Analyze last run (from e2e-run-result.yaml)
/e2e-analyze <test>         # Analyze specific test

Analysis Steps

Step 1: Load Last Run

cat apps/web/e2e-run-result.yaml

Step 2: For Each Failure, Build Timeline

Read the error-context.md file and reconstruct:

failure_timeline:
  test: "creator-detail.spec.ts:29"
  title: "should display creators list page"
  steps:
    - ts: "00:00.000"
      action: "goto('/admin/creators')"
      status: "ok"
    - ts: "00:00.850"
      action: "waitForLoadState('networkidle')"
      status: "ok"
    - ts: "00:01.200"
      action: "locator('h1').filter({hasText: /criadores/})"
      status: "timeout"
      error: "Timeout 5000ms exceeded"

  page_state:
    url: "/admin/creators"
    status_code: 404
    screenshot: "test-results/.../test-failed-1.png"

Step 3: Code Correlation

For each failure, find related code:

code_correlation:
  expected_route: "/admin/creators"

  search_results:
    - query: "glob: apps/web/src/app/**/admin/creators/**/page.tsx"
      found: false
    - query: "glob: apps/web/src/app/**/admin/**/creators/**/page.tsx"
      found: true
      path: "apps/web/src/app/(app)/admin/moderation/creators/page.tsx"

  suggestion:
    action: "test-update"
    description: "Route /admin/creators doesn't exist. Use /admin/moderation/creators instead."
    confidence: 0.95

Step 4: History Lookup

Check .e2e-history/failures.jsonl:

grep "creator-detail.spec.ts:29" .e2e-history/failures.jsonl | tail -5
grep "creator-detail.spec.ts:29" .e2e-history/resolutions.jsonl | tail -1
history:
  previous_failures: 2
  last_failure: "2026-01-15T10:30:00Z"
  last_resolution:
    date: "2026-01-15T11:00:00Z"
    type: "test-update"
    description: "Changed route from /admin/creators to /admin/moderation/creators"

  pattern_detected: "Recurring route mismatch - may indicate unstable route structure"

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.
