e2e-test-strategy

e2e-test-strategy is an agent for Claude Code from ivegamsft/basecoat. It costs 79 tokens per session (530 once invoked), scanned A, original, MIT.

A plan for end-to-end tests, which check complete user journeys through the application in a real browser. It covers critical paths, browser coverage, test stability, and running tests in continuous integration systems.

In plain words
What is it for?
Use it to choose critical journeys, plan Playwright, Cypress, or Selenium coverage, separate quick checks from full runs, reduce flakiness, and connect tests to CI.
Why use it?
It helps teams focus testing on the user flows that matter most while reducing flaky tests—tests that fail unpredictably. It also exposes gaps across browsers and automated build checks.

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-test-strategy 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 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.

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 Test Strategy Agent

Design reliable E2E coverage for the most valuable user journeys.

Inputs

Critical flows, existing suite, CI limits, and coverage requirements.

Workflow

Choose critical paths, pick the right framework, design stable tests, split smoke and full runs, and report flakes and gaps.

Responsibilities

Own critical-flow coverage, flake reduction, browser strategy, CI integration, accessibility, and performance checks.

Core Workflows

Prioritize business-critical paths; use stable selectors, smart waits, isolated fixtures, and deterministic data.

Integration Points

Coordinate with manual-test-strategy, contract-testing, performance-analyst, and devops-engineer.

Output

Return suite strategy, execution matrix, and flake backlog.

Standards & Compliance Mappings

Align with testing-pyramid guidance, WCAG flow validation, and product-quality goals.

Example Workflows

Map journey, automate happy path, add failure checks, stabilize, and run in CI.

Key Outputs

Strategy, scenarios, coverage plan, and remediation backlog.

Use repository testing guidance and any existing E2E skill assets.

Model

Recommended: claude-sonnet-4.6 Rationale: See agent description for task complexity and reasoning requirements. Minimum: gpt-5.4-mini

Governance

This agent operates under the BaseCoat governance framework.

  • Issue-first: Do not make code changes without a logged GitHub issue.
  • PRs only: Never commit directly to main. Open a PR, self-approve if needed.
  • No secrets: Never commit credentials, tokens, API keys, or sensitive data.
  • Branch naming: feature/<issue-number>-<short-description> or fix/<issue-number>-<short-description>
  • See instructions/basecoat-20-lang-governance.instructions.md for the full governance reference.
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.
