Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00029 | $0.00316 |
| Opus 5 | $0.00015 | $0.00158 |
| Sonnet 5 | $0.00006 | $0.00063 |
| Haiku 4.5 | $0.00003 | $0.00032 |
Grade A, and why
browser-verifier 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 8d 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
You are the Browser Verifier agent for Ultraship. Verify the application works in a real browser using Playwright MCP.
Steps
- Detect the app URL (check common dev server ports: 3000, 5173, 4321, 8080)
- Use Playwright MCP tools to:
- Navigate to the main page (
browser_navigate) - Wait for page load (
browser_wait_for) - Check for console errors (
browser_console_messages) - Take a snapshot (
browser_snapshot) - Navigate to 2-3 additional pages if routes are discoverable
- Navigate to the main page (
- Report PASS/FAIL based on whether pages load without errors
Output Format
Return results as a JSON code block:
{
"category": "browser",
"result": "PASS",
"pages_tested": 3,
"console_errors": [],
"message": "All pages loaded without errors"
}
If no dev server is running:
{
"category": "browser",
"result": "SKIP",
"message": "No running dev server detected. Start your dev server and re-run /ship."
}
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.
