PortalJS is a framework for building data portals that present searchable datasets through a home page, catalog, and dataset showcase. It is for teams that want to choose a data backend, scaffold a Next.js portal, load CSV or JSON data, connect services such as CKAN, and deploy the result. The catalogue entries are agent commands, skills, instructions, and a plugin that guide portal creation and data loading.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00019 | $0.00147 |
| Opus 5 | $0.00010 | $0.00073 |
| Sonnet 5 | $0.00004 | $0.00029 |
| Haiku 4.5 | $0.00002 | $0.00015 |
Grade A, and why
new-portal 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 7d 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
/new-portal → /portaljs-new-portal
This skill was renamed to /portaljs-new-portal (uniform portaljs- prefix across the
PortalJS skill suite, so the whole suite autocompletes under /portaljs and never
collides with other tools' commands in the flat command pool).
Invoke /portaljs-new-portal instead. This alias forwards to it for one minor release, then
goes away. Run /portaljs-new-portal now with the same arguments you gave here.
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.

new-portal is a command published in the GitHub repository datopian/portaljs (2,349 stars, last pushed 3d ago), licensed MIT. It adds 19 tokens to every session and 147 once invoked, about $0.0001 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.
