What Instantly Pack is

Instantly Pack is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. 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.”

A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.

Installing Instantly Pack adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.

This pack contains 24 source-grounded Claude Code skills. It treats outreach mutations, account connections, cross-workspace delegation, data handling, commercial changes, and external disclosures as explicit approval boundaries.

Current platform contract

Base URL: https://api.instantly.ai/api/v2
Authentication: scoped API v2 bearer keys
General rate limits: 100 requests/second and 6,000 requests/minute, shared across API v1/v2 and all keys in a workspace
Official SDK: @instantlyai/sdk beta, Node.js 22+
Official CLI: @instantlyai/cli, Node.js 18+
API v1: deprecated on January 19, 2026; v2 requires new, incompatible keys
Webhooks: documented event schema and management APIs; no unpublished signature or fixed retry contract is assumed

Recheck the linked first-party references before production changes because endpoint schemas, package releases, limits, plans, and commercial terms can change.

Installation

/plugin install instantly-pack@claude-code-plugins-plus

Skills

instantly-migration-deep-dive owns the one-time API v1-to-v2 cutover. instantly-upgrade-migration owns ongoing SDK, CLI, OpenAPI-type, and API v2 contract upgrades.

Safety model

Every skill is inspection-first. Live requests use bounded synthetic or approved data, least-privilege scopes, redacted evidence, and explicit workspace identity. Campaign activation, account connection, lead import/deletion, webhook changes, key/member changes, plan changes, and diagnostic sharing require accountable-owner approval.

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
