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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00085 | $0.01784 |
| Opus 5 | $0.00043 | $0.00892 |
| Sonnet 5 | $0.00017 | $0.00357 |
| Haiku 4.5 | $0.00009 | $0.00178 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vercel CLI
Safety-first wrapper for the Vercel CLI (vercel, alias vc). Every command is classified by risk tier before execution — full project control, with anything irreversible gated behind explicit confirmation.
When to Use
- Deploy projects (preview/production), build locally, or run
vercel dev - Manage env vars, secrets, and pull project settings (
env,pull) - Manage domains, DNS records, certificates, and aliases
- Manage projects, teams/scopes, and Git connections
- Inspect deployments, read logs, roll back, promote, or redeploy
- Configure firewall, routes, redirects, cache, flags, rolling releases
- Make authenticated
vercel apicalls or manage blob storage & integrations
Prerequisites
- Install:
npm i -g vercel(or pnpm/yarn). Native binary (experimental):pnpm i -g @vercel/vc-native -f - Auth:
vercel login— or for CI/CD setVERCEL_TOKEN(preferred over the--tokenflag, which leaks into process lists). Tokens: https://vercel.com/account/tokens - Verify:
vercel --versionandvercel whoami - Link:
vercel linkin the project dir (creates.vercel/) - Scope: confirm the active team with
vercel teams ls; switch withvercel switch
Safety Model
| Tier | Action Required | Examples |
|---|---|---|
| Safe | Execute immediately | vercel ls, inspect, env ls, whoami |
| Write | Inform user, then execute | deploy (preview), env add, alias set, dns add, staged routes/firewall rules edits |
| Destructive | AskUserQuestion BEFORE executing |
deploy --prod, remove, rollback, promote, env rm, alias rm, domains rm, certs rm, cache purge, firewall publish |
| Forbidden | Multi-step typed confirmation, NEVER auto-confirm | project rm, domains buy/transfer-in, buy, cache dangerously-delete, firewall system-mitigations pause, git disconnect, bulk destructive loops |

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 georgekhananaev/claude-skills-vault (28 stars, last pushed 1mo ago), licensed MIT. It adds 85 tokens to every session and 1,784 once invoked, about $0.0004 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 2026-09-03.
