Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@agentpki/scopes

v0.1.0

Published

Pre-built capability scope templates for AgentPKI passports. Standardizes scope strings across the ecosystem so issuers, agents, and verifiers all speak the same language.

Readme

@agentpki/scopes

Pre-built capability scope templates for AgentPKI passports. Use these instead of inventing your own scope strings — every site verifying AgentPKI tokens will recognize them.

Install

npm i @agentpki/scopes

Quick start

import { AgentPKI } from '@agentpki/sdk';
import { Scopes } from '@agentpki/scopes';

const client = new AgentPKI({ passportProvider });

// Mint a passport with a pre-built scope pack:
const token = await client.mint({
  sub: 'agent:mybot/v1',
  scope: Scopes.commerce.checkout({ maxUsd: 100 }),
});
// scope: ['read:catalog', 'read:availability', 'read:pricing', 'read:reviews',
//         'request:quote', 'accept:quote', 'purchase:<=100usd',
//         'read:receipt', 'read:order-status', 'request:refund']

Built-in scope packs

Commerce

| Pack | Description | |---|---| | Scopes.commerce.readOnly | Browse-only: catalog, availability, pricing, reviews. | | Scopes.commerce.checkout({ maxUsd }) | Full checkout up to N USD per transaction. | | Scopes.commerce.subscriptionManagement({ maxUsdPerPeriod }) | Manage recurring billing. |

Scheduling

| Pack | Description | |---|---| | Scopes.scheduling.readOnly | Read calendar + availability. | | Scopes.scheduling.fullAccess | Book, reschedule, cancel, invite. | | Scopes.scheduling.windowed({ from, to }) | Scheduling constrained to a time window. |

News / Content

| Pack | Description | |---|---| | Scopes.news.researchBot | Articles + headlines + metadata + public data. | | Scopes.news.aggregator | Headlines + RSS + sitemap. |

Medical (requires Tier-2 issuer)

| Pack | Description | |---|---| | Scopes.medical.triage | Public health info + drug DB. No PHI. | | Scopes.medical.telehealthScheduling | Schedule / reschedule / cancel visits. | | Scopes.medical.patientRecordsReadonly | Read own records + lab results. |

Financial (requires Tier-2 issuer)

| Pack | Description | |---|---| | Scopes.financial.research | Market data + filings + rates. | | Scopes.financial.accountReadonly | Read balance + transactions + statements. | | Scopes.financial.payBills({ maxPerTransactionUsd, maxDailyUsd }) | Pay bills with daily and per-tx caps. |

Helpers

import { union, satisfies, parse } from '@agentpki/scopes';

// Combine multiple packs:
const combined = union(
  Scopes.commerce.readOnly,
  Scopes.scheduling.fullAccess,
);

// Check if a passport satisfies required scopes:
const ok = satisfies(passportToken.scope, [Scopes.commerce.READ_CATALOG]);

// Parse a parameterized scope:
const parsed = parse('purchase:<=100usd');
// { raw: 'purchase:<=100usd', action: 'purchase', resource: null,
//   constraints: { usd: '<=100' } }

Why standardize?

Every AgentPKI verifier needs to enforce scope semantics consistently. If Anthropic's agent says purchase:limit_100_usd and DataDome expects purchase:<=100usd, both sides have to maintain mapping tables forever.

By using @agentpki/scopes, you guarantee:

  • Your scope strings match every other AgentPKI integration's
  • Verifiers don't need vendor-specific shims to enforce limits
  • The protocol stays one source of truth

If a pack is missing for your industry, open an issue. We add scopes in batches as the ecosystem coalesces.

Adding a new vertical

PRs welcome. New verticals live in src/<vertical>.ts and are added to the top-level Scopes export in src/index.ts. Each vertical should:

  1. Export individual scope strings as named constants (UPPER_SNAKE_CASE)
  2. Export common packs as readonly arrays
  3. Export parameterized scope generators as functions
  4. Document any Tier-2 / Tier-3 issuer requirements in comments
