What is create-port-plugin?

A toolkit for building Port plugins: small React and TypeScript widgets that run in an iframe and are uploaded to Port, a developer portal platform.

Creating new Port widgets, adapting existing plugins, finding a suitable plugin in a repository, and checking plugins before upload.

It guides plugin creation, reuse, checking, and adaptation so developers do not have to work out the structure and verification process alone.

Token cost

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	$0.00102	$0.00227
Opus 5.5	$0.00041	$0.00091
Sonnet 5.5	$0.00020	$0.00045
Haiku 4.5	$0.00010	$0.00023

Security

Grade A, and why

create-port-plugin 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 2mo 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.

Create a Port Plugin

This file is a stub. Follow the canonical skill only:

Read .cursor/skills/create-port-plugin/SKILL.md in full before any plugin work.
Use templates from .cursor/skills/create-port-plugin/assets/ and references from .cursor/skills/create-port-plugin/references/ — do not use .claude/skills/create-port-plugin/ for content.

Changes

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.
