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

mobilewright AGENTS.md 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 4d 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.

AGENTS.md

Guidance for agents working in Mobilewright, from local investigation through pull requests. Read this file before making changes and any scoped AGENTS.md in the affected directories. CONTRIBUTING.md owns setup, issue reporting, approval requirements, and PR conventions.

Repository map

Mobilewright is a TypeScript ESM monorepo using npm workspaces and Node.js 22.12+.

Path Responsibility
packages/mobilewright-core Device, screen, page, locator, and assertion APIs
packages/protocol Shared driver interfaces and types
packages/driver-mobilecli Adapter to the local mobilecli device backend
packages/driver-mobilenext Adapter to the MobileNext service
packages/mobilewright Public package, configuration, launchers, and mobilewright CLI
packages/test Playwright test fixtures and test integration
packages/cli mobilewright-cli, the CLI for coding agents
packages/inspector Browser-based inspector and its server
docs User-facing documentation
tests/mobilewright.config.ts Configuration for colocated package tests

Keep device-backend details in the appropriate driver and shared contracts in packages/protocol. Follow existing package boundaries instead of importing another package's private implementation.

Working agreement

  • Inspect git status before editing. Preserve unrelated changes and untracked files; do not reset, stash, or switch branches underneath other work.
  • Read the affected implementation, callers, and tests before changing behavior. Fix the cause in the owning layer.
  • Keep the smallest coherent change that solves the problem. Do not reformat unrelated code or rename unrelated symbols or files.
  • Follow the approval rules. A direct maintainer request supplies approval for its stated scope; do not ask for the same approval again. Required tracking issues still apply.
  • Preserve existing macOS, Linux, and Windows host support. Do not remove or break Windows code paths because you cannot build or test them locally; say in the PR what you could not verify. Device capabilities remain platform-dependent; local iOS simulators require macOS.

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.
