Best AI Skills for Enterprise in 2026: 15 Compared
Top 15 enterprise-integration skills for Claude Code, ranked. GitHub leads, but two AI-makes-phone-calls skills crack the top 5 — a 2026 trend nobody saw coming.
"Enterprise" in the Claude Code catalog means integration with the SaaS tools your team already uses. The catalog has 499 skills here — the deepest pool of any category — and the top 15 ranks GitHub at #1 (145K signal, biggest in this article) with predictable suspects following: Notion, Slack, Trello, Gmail. The non-obvious data point: two of the top 5 are AI-makes-phone-calls skills (PollyReach at #2, Agent Phone Call at #4). Twelve months ago, "give your agent a phone number" was a curiosity. In 2026 it's a top-5 enterprise pattern, mostly because agents that can complete tasks over the phone unlock workflows (vendor calls, appointment booking, customer follow-up) that no other integration covers.
Quick Pick
Github — The single most-installed enterprise skill (145K signal). It wraps the gh CLI so Claude can do gh issue, gh pr, gh run, and gh api without you re-explaining the flags each time. Quick to install, near-zero learning curve, immediate value for any team doing pull-request-driven development.
What These Skills Actually Do
Enterprise skills fall into five patterns: (1) Direct SaaS integrations (GitHub #1, Notion #5, Trello #10, Slack #7, Gmail #11, Discord #13, Xiaohongshu #12) — one skill, one product. Easy to evaluate: do you use the tool, and does the skill cover the operations you care about? (2) Multi-API gateways (API Gateway #6) — single skill, 100+ services with managed OAuth. Trades depth for breadth. (3) Communication channels (PollyReach #2, Agent Phone Call #4) — agents that complete tasks over the phone. New in 2026, real demand. (4) Email primitives (Himalaya #8, imap-smtp-email #9, AgentMail #14) — the inbox is a sync point for half of business workflows, and four of the top 15 are email-related. AgentMail is the standout because it's the only one built specifically for agents (dedicated inbox + webhooks) rather than repurposing human email tooling. (5) Calendar & devices (CalDAV #15, Sonos #3) — long-tail, but they appear here because agents-do-physical-world tasks are increasing. What separates a great enterprise skill from a mediocre one: whether it handles authentication cleanly (most users will not configure 12 OAuth flows), and whether the skill's intent triggers match how humans phrase requests.
How We Ranked
We sorted 15 candidate skills by a composite score:
- Popularity signal — the highest of GitHub stars, install count, or ClawHub download count. Log-scaled so a 100-star skill doesn't get buried under a 100,000-star one if the smaller one is meaningfully better.
- Quality score — when set, a 0–5 rubric that breaks ties within popularity tiers. Roughly 15% of catalog skills carry a quality score today; we surface it in the comparison table when available.
The formula is identical across the entire Best-Of 2026 series, so you can compare apples to apples between categories.
The Top 15
1. Github
Skill · clawhub/github · 145.0K signal · quality unrated
Interact with GitHub using the gh CLI. gh issue, gh pr, gh run, gh api for issues, PRs, CI runs, advanced queries.
The take: The highest-signal skill in any enterprise-adjacent category. It wins on simplicity: wrap a CLI that exists, expose its verbs to Claude, done. The CLI being battle-tested by GitHub itself means there's no auth or rate-limit logic to reinvent. The 145K signal reflects that almost everyone using Claude Code is shipping code, and almost everyone shipping code uses GitHub.
2. PollyReach
Skill · pollyreach/pollyreach · 95.9K signal · quality unrated Give every AI agent a phone number — find contacts, make calls, complete tasks.
The take: First of two phone-call skills in the top 5 (see #4 — same product category, different vendor). The 95.9K signal is the genuinely surprising data point of this whole article: a year ago "AI agents that call vendors for you" was speculative; in 2026 it's installed nearly as often as Notion. Use cases that justify the install: appointment booking, vendor price-checks, callback scheduling, anything that requires a phone but doesn't require a human voice.
3. Sonoscli
Skill · steipete/sonoscli · 72.4K signal · quality unrated Control Sonos speakers — discover, status, play, volume, group.
The take: Edge of the category — more "smart home" than enterprise, but enterprise here is loosely defined and the install signal is too high to ignore. Useful for office-environment automation (boardroom music, all-hands announcement systems) and for developers who just want Claude to manage their home speaker system from the IDE. Niche, but the install volume tells you it's a niche people care about.
4. Agent Phone Call
Skill · mrsz/agent-phone-call · 71.9K signal · quality unrated Same category as #2 — agent-makes-phone-calls — different implementation.
The take: Functional twin of #2 PollyReach. The fact that the catalog has two near-identical skills both ranking top 5 reflects how new the "agent phone call" category is — no winner-take-all leader yet. Install one, not both. Differences are minor: PollyReach has a more polished onboarding flow; Agent Phone Call has slightly broader country coverage at the time of writing.
5. Notion
Skill · clawhub/notion · 71.4K signal · quality unrated Notion API for creating and managing pages, databases, and blocks.
The take: Solid Notion wrapper. The pages-and-databases coverage is what matters — Notion's value is in its database/blocks model, and the skill exposes that cleanly. Pair with #1 GitHub for "issue-to-Notion-page" workflows or with #7 Slack for "summarize this thread into a Notion doc" pipelines.
6. API Gateway
Skill · clawhub/api-gateway · 61.7K signal · quality unrated Connect to 100+ APIs (Google Workspace, Microsoft 365, GitHub, Notion, Slack, Airtable, HubSpot, etc.) with managed OAuth.
The take: The "one skill to rule them all" pattern. Trades depth for breadth — for any single integration, the dedicated skill is going to be better. But the managed OAuth alone is worth the install: 100+ services, one auth dance, every API at Claude's fingertips. Use as a fallback for tools that don't have dedicated skills yet.
7. SlackHighlighted
Skill · clawhub/slack · 35.6K signal · quality unrated Control Slack from Claude — react, pin, send messages, manage channels/DMs.
The take: Standard Slack integration. The reactions / pinning features beyond just "send message" are the differentiator — most agents-and-Slack integrations are write-only, this one supports curation. Pair with the Discord skill (#13) if your team uses both.
8. Himalaya
Skill · lamelas/himalaya · 34.8K signal · quality unrated CLI for IMAP/SMTP — list, read, write, reply, forward, search, organize from the terminal. Multi-account, MIME composition.
The take: Best of the IMAP-based email skills. Himalaya the CLI is mature and tested by long-time Linux email users; this skill wraps it for Claude. Use when you want full email control (not just send/receive) — search, multi-account, folder management, MIME attachments. Stronger than #9 on advanced operations; weaker than #11 Gmail if you only use Gmail (no OAuth needed there).
9. imap-smtp-email
Skill · gzlicanyi/imap-smtp-email · 34.1K signal · quality unrated IMAP/SMTP email — check new/unread, fetch, search, mark read, send with attachments.
The take: Lighter alternative to #8 Himalaya. Same fundamentals (IMAP/SMTP) but a simpler API surface. Install if you want basic send/receive without learning Himalaya's idioms. The 34K signal nearly-ties with #8 — they're functional competitors.
10. TrelloHighlighted
Skill · steipete/trello · 32.0K signal · quality unrated Manage Trello boards, lists, and cards via REST API.
The take: Trello's API is older and simpler than Notion's, which is reflected in this skill's small scope (just boards/lists/cards, no fancy automation). If your team still uses Trello in 2026, this works. If you're on Notion or Linear, install those instead.
11. Gmail
Skill · clawhub/gmail · 28.3K signal · quality unrated Gmail API with managed OAuth. Read, send, manage emails, threads, labels, drafts.
The take: Dedicated Gmail integration — beats the generic IMAP skills (#8, #9) for Gmail users because it uses Gmail's native API (labels, threads, search operators) instead of generic IMAP commands. Managed OAuth means no app-password setup. If you're a Gmail-only team, install this instead of Himalaya.
12. Xiaohongshu (小红书) Automation
Skill · borye/xiaohongshu-mcp · 28.1K signal · quality unrated Xiaohongshu (RedNote) automation via Python client + MCP server. Publishing image/text/video, search, trends.
The take: Sister skill to the RedNote skill in the marketing list but with broader automation scope (this one includes search-for-trends). For brands targeting China-market consumers, RedNote is the discovery platform — this is the API-level access.
13. Discord
Skill · steipete/discord · 27.2K signal · quality unrated Control Discord — send, react, stickers, emojis, polls, threads, pins, search, permissions, members.
The take: The most feature-complete community-platform skill in the top 15. Polls and thread management put it above generic "send a message" wrappers. If your community lives on Discord, install this. If on Slack, install #7. Many teams have both — install both.
14. AgentMail
Skill · adboio/agentmail · 24.2K signal · quality unrated API-first email platform designed for AI agents — dedicated inboxes, programmatic send/receive, webhooks, real-time events.
The take: The only email skill on the list purpose-built for agents. The dedicated-inbox-per-agent pattern (rather than sharing your human inbox) is the real value — your agent's email doesn't pollute your own, webhooks fire on incoming messages, and the rate limits are tuned for automated workflows. If you're building any agent that needs an email address, this beats the IMAP-based options.
15. Caldav CalendarHighlighted
Skill · asleep123/caldav-calendar · 23.8K signal · quality unrated CalDAV sync — iCloud, Google, Fastmail, Nextcloud calendars via vdirsyncer + khal. Linux.
The take: Specifically CalDAV (the open standard), not vendor APIs. Useful if your calendar lives across multiple providers and you need a unified query layer; less useful if you only use Google Calendar (in which case dedicated Google integration would be cleaner). Linux-only.

FAQ
How is this list different from the category page on aiskill.market?
The category page is a directory: every skill in the category, sortable and filterable. This list is editorial — opinionated, time-stamped (2026-05-18), and ranked. Use the directory when you know what you want; use this when you don't.
Why does the #1 pick have fewer stars than #5?
Stars are one signal among several. The composite score above also includes install counts (which reflect actual usage on aiskill.market) and the optional quality score. A skill with a smaller star count can rank higher if its installs or quality score are strong enough to offset.
Are these all free?
The skills themselves are open source. Most of the underlying services are paid at any non-trivial usage: PollyReach (#2) and Agent Phone Call (#4) charge per-call (telephony costs are real); Notion (#5), Trello (#10), Slack (#7) all have free tiers but enterprise features require paid plans; AgentMail (#14) is a paid hosted service. GitHub (#1), Gmail (#11), and the IMAP skills (#8, #9) are free for personal/small-team use.
How do I install one?
Each linked skill page has install instructions. The fastest path is the one-line install via the aiskill.market CLI or by adding the source repo as a Claude Code plugin marketplace.
How often does this list update?
Quarterly. Enterprise tooling is the most stable category — SaaS APIs change slowly, OAuth flows are settled. Expect ranking shifts within the top 15 but few new entrants displacing the leaders.
Should I use API Gateway or a dedicated skill?
Use the dedicated skill when the integration is core to your workflow (GitHub, Slack, your CRM) — dedicated skills have richer feature coverage and better intent triggers. Use API Gateway (#6) for one-off integrations or for prototyping before committing to a dedicated skill. Running both costs almost nothing — they don't conflict.
What's the right starter pack for a 5-person team?
Four skills covers most workflows: #1 GitHub (code), #5 Notion (docs/wiki) or #10 Trello (projects), #7 Slack (chat), and one email skill (#11 Gmail if you're on Google Workspace, #8 Himalaya if mixed/self-hosted). Add #14 AgentMail if you're building agents that need their own inbox; add #2 or #4 if any workflow involves making phone calls.
