What it does

Upgrade Stripe is an agent skill from kanchengw/cnllm. Guide for upgrading Stripe API versions and SDKs

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Building AI agents. It works with Stripe, Python, LangChain and LlamaIndex. The repository describes itself as: Python toolkit for Chinese LLMs, with flexible batch capacity, structured real-time visulization and automated accumulation for streaming, and explicit feedback on vendor-native… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Building AI agents

Example prompts

  • “/upgrade-stripe”

Requirements

  • Python 3
  • Node.js

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Identify your current API version in code
  2. Review the changelog for relevant changes
  3. Consider gradually updating your API version before switching Stripe.js versions
  4. Stripe continues supporting v3 indefinitely

What it can do on your machine

Read from SKILL.md and the folder at commit 7fadd83. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • curl
    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • js.stripe.com
    • api.stripe.com

    Also links to:

    • docs.stripe.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Upgrade Stripe loads about 1.4k tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 571 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~16
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Guide for upgrading Stripe API versions and SDKs

The latest Stripe API version is 2026-05-27.dahlia - use this version when upgrading unless the user specifies a different target version.

Upgrading Stripe Versions

This guide covers upgrading Stripe API versions, server-side SDKs, Stripe.js, and mobile SDKs.

Understanding Stripe API Versioning

Stripe uses date-based API versions (e.g., 2026-05-27.dahlia, 2025-08-27.basil, 2024-12-18.acacia). Your account’s API version determines request/response behavior.

Types of Changes

Backward-Compatible Changes (don’t require code updates):

  • New API resources
  • New optional request parameters
  • New properties in existing responses
  • Changes to opaque string lengths (e.g., object IDs)
  • New webhook event types

Breaking Changes (require code updates):

  • Field renames or removals
  • Behavioral modifications
  • Removed endpoints or parameters

Review the API Changelog for all changes between versions.

Server-Side SDK Versioning

See SDK Version Management for details.

Dynamically-Typed Languages (Ruby, Python, PHP, Node.js)

These SDKs offer flexible version control:

Global Configuration:

python
import stripe
stripe.api_version = '2026-05-27.dahlia'
ruby
Stripe.api_version = '2026-05-27.dahlia'
javascript
const stripe = require('stripe')('sk_test_xxx', {
  apiVersion: '2026-05-27.dahlia'
});

Per-Request Override:

python
stripe.Customer.create(
  email="customer@example.com",
  stripe_version='2026-05-27.dahlia'
)
Strongly-Typed Languages (Java, Go, .NET)

These use a fixed API version matching the SDK release date. Don’t set a different API version for strongly-typed languages because response objects might not match the strong types in the SDK. Instead, update the SDK to target a new API version.

Best Practice

Always specify the API version you’re integrating against in your code instead of relying on your account’s default API version:

javascript
// Good: Explicit version
const stripe = require('stripe')('sk_test_xxx', {
  apiVersion: '2026-05-27.dahlia'
});

// Avoid: Relying on account default
const stripe = require('stripe')('sk_test_xxx');

Stripe.js Versioning

See Stripe.js Versioning for details.

Stripe.js uses an evergreen model with major releases (Acacia, Basil, Clover, Dahlia) on a biannual basis.

Loading Versioned Stripe.js

Via Script Tag:

html
<script src="https://js.stripe.com/dahlia/stripe.js"></script>

Via npm:

bash
npm install @stripe/stripe-js

Major npm versions correspond to specific Stripe.js versions.

API Version Pairing

Each Stripe.js version automatically pairs with its corresponding API version. For instance:

  • Dahlia Stripe.js uses 2026-05-27.dahlia API
  • Acacia Stripe.js uses 2024-12-18.acacia API

You can’t override this association.

Migrating from v3
  1. Identify your current API version in code
  2. Review the changelog for relevant changes
  3. Consider gradually updating your API version before switching Stripe.js versions
  4. Stripe continues supporting v3 indefinitely

Mobile SDK Versioning

See Mobile SDK Versioning for details.

iOS and Android SDKs

Both platforms follow semantic versioning (MAJOR.MINOR.PATCH):

  • MAJOR: Breaking API changes
  • MINOR: New functionality (backward-compatible)
  • PATCH: Bug fixes (backward-compatible)

New features and fixes release only on the latest major version. Upgrade regularly to access improvements.

Show full SKILL.md (213 more words)Show less
React Native SDK

Uses a different model (0.x.y schema):

  • Minor version changes (x): Breaking changes AND new features
  • Patch updates (y): Critical bug fixes only
Backend Compatibility

All mobile SDKs work with any Stripe API version you use on your backend unless documentation specifies otherwise.

Upgrade Checklist

  1. Review the API Changelog for changes between your current and target versions
  2. Check Upgrades Guide for migration guidance
  3. Update server-side SDK package version (e.g., npm update stripe, pip install --upgrade stripe)
  4. Update the apiVersion parameter in your Stripe client initialization
  5. Test your integration against the new API version using the Stripe-Version header
  6. Update webhook handlers to handle new event structures
  7. Update Stripe.js script tag or npm package version if needed
  8. Update mobile SDK versions in your package manager if needed
  9. Store Stripe object IDs in databases that accommodate up to 255 characters (case-sensitive collation)

Testing API Version Changes

Use the Stripe-Version header to test your code against a new version without changing your default:

bash
curl https://api.stripe.com/v1/customers \
  -u sk_test_xxx: \
  -H "Stripe-Version: 2026-05-27.dahlia"

Or in code:

javascript
const stripe = require('stripe')('sk_test_xxx', {
  apiVersion: '2026-05-27.dahlia'  // Test with new version
});

Important Notes

  • Your webhook listener should handle unfamiliar event types gracefully
  • Test webhooks with the new version structure before upgrading
  • Breaking changes are tagged by affected product areas (Payments, Billing, Connect, etc.)
  • Multiple API versions coexist simultaneously, enabling staged adoption
