Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00070 | $0.01094 |
| Opus 5 | $0.00035 | $0.00547 |
| Sonnet 5 | $0.00014 | $0.00219 |
| Haiku 4.5 | $0.00007 | $0.00109 |
Grade A, and why
eve-web-ui-testing-agent-browser scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web UI Testing with agent-browser
Use agent-browser as the default CLI for deterministic UI checks in app repos. Inside the Eve Horizon repo itself, prefer the repo-pinned Playwright wrapper (see "Eve Horizon Repo Wrapper" below).
Install agent-browser
# macOS/Linux (recommended)
npm install -g agent-browser
agent-browser install
# Linux containers/VMs that need extra browser libs
agent-browser install --with-deps
Alternative install on macOS:
brew install agent-browser
agent-browser install
Configure for Reliable Runs
Use isolated state for each test target:
# one session per test flow
agent-browser --session login-flow open https://example.com
# persistent auth/session state per app
agent-browser --profile ~/.agent-browser/myapp open https://example.com
Set environment variables for CI:
export AGENT_BROWSER_SESSION=ci
export AGENT_BROWSER_PROFILE="$PWD/.tmp/agent-browser-profile"
export AGENT_BROWSER_PROVIDER=local
Optional cloud providers:
- Browserbase: set
AGENT_BROWSER_PROVIDER=browserbase,BROWSERBASE_API_KEY,BROWSERBASE_PROJECT_ID - Browser Use: set
AGENT_BROWSER_PROVIDER=browseruse,BROWSER_USE_API_KEY - Kernel: set
AGENT_BROWSER_PROVIDER=kernel,KERNEL_API_KEY
For proxy testing:
export AGENT_BROWSER_PROXY="http://user:pass@proxy-host:port"
Install the Upstream Skill (Optional)
If your runtime supports skill installation, add the upstream skill:
eve skill install https://github.com/vercel-labs/agent-browser
Core Workflow
Run every flow in this sequence:
- Navigate:
agent-browser open <url> - Snapshot interactive refs:
agent-browser snapshot -i - Interact with refs:
agent-browser click @e1,agent-browser fill @e2 "value" - Re-snapshot after page changes:
agent-browser snapshot -i - Assert output:
agent-browser get text <selector-or-ref> - Capture artifacts:
agent-browser screenshot <path>

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.
