Upgrade Gamma SDK versions and migrate between API versions.

  • Works in 7 steps: Check Current Version → Review Changelog → Upgrade SDK → …
  • Upgrading SDK packages
  • SKILL.md covers Output, Error Handling, Examples and Current State, plus 7 more sections
  • Calls npm, pip and git; reaches gamma.app; needs GAMMA_API_KEY

What it does

Gamma Upgrade Migration is an agent skill from jeremylongshore/tons-of-skills-marketplace. Upgrade Gamma SDK versions and migrate between API versions. Use when upgrading SDK packages, handling deprecations, or migrating to new API versions. Trigger with phrases like "gamma upgrade", "gamma migration", "gamma new version", "gamma deprecated", "gamma SDK update".

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code

It sits in Development. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Upgrading SDK packages
  • Handling deprecations
  • Migrating to new API versions
  • With phrases like gamma upgrade

Example prompts

  • “gamma upgrade”
  • “gamma migration”
  • “gamma new version”
  • “/gamma-upgrade-migration”

Requirements

  • Python 3
  • Node.js
  • A credential in GAMMA_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(npm:*), Bash(pip:*), Grep

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Check Current Version
  2. Review Changelog
  3. Upgrade SDK
  4. Handle Breaking Changes
  5. Update Type Definitions
  6. Test Thoroughly
  7. Deprecation Handling

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash(npm:*)
    • Bash(pip:*)
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • pip
    • git
    • node

    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:

    • gamma.app

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • GAMMA_API_KEY

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

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Gamma Upgrade Migration loads about 1.2k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 194 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

Gamma Upgrade & Migration

Output

Maintain an upgrade receipt with versions reviewed, affected integrations, compatibility/canary outcome, owner approval, and rollback state. Exclude content, viewer data, and credentials.

Error Handling

Stop promotion on schema, publishing, sharing, access, or destination mismatches; restore the prior configuration and quarantine opaque failures for review.

Examples

Test an upgrade with a fictional staging deck, verify a protected sharing setting remains intact, and roll back on a synthetic integration failure.

Current State

!npm list 2>/dev/null | head -20 !pip freeze 2>/dev/null | head -20

Overview

Guide for upgrading Gamma SDK versions and migrating between API versions safely.

Prerequisites

  • Existing Gamma integration
  • Version control (git)
  • Test environment available

Instructions

Step 1: Check Current Version
bash
set -euo pipefail
# Node.js
npm list @gamma/sdk

# Python
pip show gamma-sdk

# Check for available updates
npm outdated @gamma/sdk
Step 2: Review Changelog
bash
set -euo pipefail
# View changelog
npm info @gamma/sdk changelog

# Or visit
# https://gamma.app/docs/changelog
Step 3: Upgrade SDK
bash
set -euo pipefail
# Create upgrade branch
git checkout -b feat/gamma-sdk-upgrade

# Node.js - upgrade to latest
npm install @gamma/sdk@latest

# Python - upgrade to latest
pip install --upgrade gamma-sdk

# Or specific version
npm install @gamma/sdk@2.0.0
Step 4: Handle Breaking Changes

Common Migration Patterns:

typescript
// v1.x -> v2.x: Client initialization change
// Before (v1)
import Gamma from '@gamma/sdk';
const gamma = new Gamma(apiKey);

// After (v2)
import { GammaClient } from '@gamma/sdk';
const gamma = new GammaClient({ apiKey });
typescript
// v1.x -> v2.x: Response format change
// Before (v1)
const result = await gamma.createPresentation({ title: 'Test' });
console.log(result.id);

// After (v2)
const result = await gamma.presentations.create({ title: 'Test' });
console.log(result.data.id);
typescript
// v1.x -> v2.x: Error handling change
// Before (v1)
try {
  await gamma.create({ ... });
} catch (e) {
  if (e.code === 'RATE_LIMIT') { ... }
}

// After (v2)
import { RateLimitError } from '@gamma/sdk';
try {
  await gamma.presentations.create({ ... });
} catch (e) {
  if (e instanceof RateLimitError) { ... }
}
Step 5: Update Type Definitions
typescript
// Check for type changes
// tsconfig.json - ensure strict mode catches issues
{
  "compilerOptions": {
    "strict": true,
    "noImplicitAny": true
  }
}

// Run type check
npx tsc --noEmit
Step 6: Test Thoroughly
bash
set -euo pipefail
# Run unit tests
npm test

# Run integration tests
npm run test:integration

# Manual smoke test
node -e "
const { GammaClient } = require('@gamma/sdk');
const g = new GammaClient({ apiKey: process.env.GAMMA_API_KEY });
g.ping().then(() => console.log('OK')).catch(console.error);
"
Step 7: Deprecation Handling
typescript
// Enable deprecation warnings
const gamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY,
  showDeprecationWarnings: true,
});

// Migrate deprecated methods
// Deprecated
await gamma.getPresentations();

// New
await gamma.presentations.list();
