ai-blueprint: Skill for Claude Code

.agents/skills/browser-tests/SKILL.md

browser-tests is a skill for Claude Code, Codex from aiblueprinthq/ai-blueprint. It costs 54 tokens per session (1,217 once invoked), scanned A, original, MIT.

A repository-owned setup for repeatable browser tests, using an existing test runner or Playwright, a tool for testing websites and browser extensions.

In plain words
What is it for?
Adding browser or end-to-end tests, installing Playwright, creating a browser test harness, and checking website or browser-extension flows repeatedly.
Why use it?
It gives browser behavior a consistent test path instead of relying only on manual checks. It also preserves existing project choices where possible.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is aiblueprinthq/ai-blueprint's own configuration. It tells Claude Code and Codex how to work on ai-blueprint itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-blueprint configures →

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

browser-tests 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 6d 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.

browser-tests - set up repeatable browser verification

Context reuse: Reuse any required file already loaded in project instructions or the current session. Read it again only if absent, changed, or exact current bytes or line references are needed.

First action: Before project inspection, preflight, or any other tool call, publish running to blueprint/.state/run.json using the dashboard activity contract in AGENTS.md.

This is an explicit optional setup command. It creates a project-owned browser test path that later Feature, Implement, Check, and Continuous runs can reuse. It does not replace live browser inspection, install during another workflow command, or make browser testing mandatory for every Blueprint project.

Input

No argument is required. A named runner, browser, application surface, or flow is a preference to verify against the real project.

Step 1 - inspect the project

Read enough files to identify the actual browser surface and existing setup:

  • AGENTS.md, especially Commands and any Verify command
  • package or language manifests, lockfiles, workspaces, and runtime versions
  • existing browser, integration, and end-to-end test configs and files
  • build, dev, preview, extension-build, and test commands
  • relevant CI workflows and ignore rules
  • blueprint/context/coding-standards.md
  • Git branch and worktree state

Do not assume Node.js, npm, a web server, or a blank test setup. Do not install dependencies or edit files during inspection.

Step 2 - choose the smallest useful harness

Reuse a working browser runner already established by the project. For a compatible JavaScript or TypeScript web app or browser extension with no runner, prefer Playwright Test. If the stack or executable surface is unclear, stop and ask instead of inventing a framework.

Choose one representative smoke path through a real project surface. It must prove the harness can launch the app and observe behavior, not merely assert that a static fixture exists. Keep authentication state, profiles, secrets, generated reports, traces, videos, and screenshots out of Git unless the project already has a deliberate safe convention.

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.
