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 | $0.00038 | $0.01166 |
| Opus 5 | $0.00019 | $0.00583 |
| Sonnet 5 | $0.00008 | $0.00233 |
| Haiku 4.5 | $0.00004 | $0.00117 |
Grade A, and why
vercel-cli 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.
How it starts
The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vercel CLI
You can deploy web applications to Vercel using the vercel CLI.
HARD RULE: You MUST NOT write HTML, CSS, or JavaScript yourself. When asked to build a website or web app, you MUST delegate to a Frontend Engineer subagent (see "Building Websites" section below). This is not optional. Violation wastes your context window on code that belongs in a separate agent.
Auth
Auth is handled by OneCLI — the HTTPS_PROXY injects the real token into API requests automatically. The Vercel CLI requires a token to be present to skip its local credential check, so always pass --token placeholder on every command. OneCLI replaces this with the real token at the proxy level.
Before any Vercel operation, verify auth:
vercel whoami --token placeholder
If this fails with an auth error, ask the user to add a Vercel token to OneCLI. They can create one at https://vercel.com/account/tokens and register it via onecli secrets create on the host. Once added, retry vercel whoami.
Deploying
Always use --yes to skip interactive prompts and --token placeholder for auth (OneCLI replaces with real token).
# Deploy to production
vercel deploy --yes --prod --token placeholder
# Deploy from a specific directory
vercel deploy --yes --prod --token placeholder --cwd /path/to/project
# Preview deployment (not production)
vercel deploy --yes --token placeholder
After deploying, verify the live URL:
# Check deployment status
vercel inspect <deployment-url> --token placeholder
If you have agent-browser available, open the deployed URL and take a screenshot to visually verify.
Project Management
# Link to an existing Vercel project (non-interactive)
vercel link --yes --token placeholder
# List recent deployments
vercel ls --token placeholder
# List all projects
vercel project ls --token placeholder
Domains
# List domains
vercel domains ls --token placeholder
# Add a domain to the current project
vercel domains add example.com --token placeholder
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.

vercel-cli is a skill published in the GitHub repository suyoumo/ClawProBench (823 stars, last pushed 7d ago), licensed Apache-2.0. It adds 38 tokens to every session and 1,166 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
