Install three free things first: Anthropic’s Marketing plugin (it ships a HubSpot MCP connector), Corey Haines’ marketingskills for ICP, case-study and sales-enablement work, and claude-ads if you own LinkedIn Ads. Pairing skills with a CRM connector matters more in B2B than anywhere else, because a buying committee sees every asset and generic AI drafts forget your ICP between sessions and invent customer quotes when they run out of facts.
This guide is for B2B marketers: demand gen, ABM leads, content and field marketing. It is research-based. We read each repo, pulled GitHub data with gh api on 2 November 2026 and checked prices on live pages. We did not run these tools against a live pipeline, so no performance results are claimed.
Two sibling guides cover nearby ground. If you run outbound or own quota, read Claude Code skills for sales teams. If you own positioning, launches and battlecards, read Claude Code skills for product marketers. This one sits between them: the marketing side of account-based, committee-driven selling.
Quick answer: which Claude Code skills should a B2B marketing team install?
Start with three free installs: Anthropic’s official Marketing plugin (which ships with a HubSpot MCP connector), Corey Haines’ marketingskills for ICP, case-study and sales-enablement work, and claude-ads if LinkedIn Ads is a channel you own. Add ZenABM’s open-source plugins only if you already pay for ZenABM. Everything else is optional depth.

How skills, plugins and MCP servers fit together for B2B
A skill is the instructions, a plugin is a bundle of skills and connectors you install in one step, and an MCP server is the live data pipe. B2B work needs all three, because your best inputs (deal stages, engaged accounts, closed-won reasons) live in a CRM, not in a prompt.
Here is how the layers split:
| Layer | What it is | B2B example |
|---|---|---|
| Skill | A SKILL.md with steps, rules and output format | ”Write a case study from an interview transcript, using only quoted facts” |
| Plugin | Skills plus MCP config plus slash commands | Anthropic marketing plugin with HubSpot, Ahrefs and Similarweb connectors |
| MCP server | A service Claude can query and update | HubSpot remote MCP at mcp.hubspot.com |
| Context files | Your ICP, messaging, approved claims | icp.md, proof-library.md in the project folder |
Why context files matter more in B2B
Consumer copy can survive on a brand voice file. B2B copy cannot. Each asset has to name the right persona, the right pain for that persona and a proof point you are allowed to use. Put three files in your project folder before you install anything:
icp.md: firmographics (industry, headcount, region, tech stack), the buying committee and disqualifiers.messaging.md: value props per persona, in your words.proof-library.md: every customer stat, quote and logo you have written permission to use, with the source and the date approved.
Skills that read these files stop guessing. Skills that cannot find them should be told to stop and ask. That one rule prevents most of the problems covered later in this guide.
Takeaway: install the data pipe and the context files before you judge any skill’s output.
The 10 best Claude Code skills and connectors for B2B marketing
Star counts and push dates come from the GitHub API on 2 November 2026. Stars measure attention, not quality. Read every SKILL.md before you roll a skill out to a team.
1. Anthropic Marketing plugin (free, official)
- Source: github.com/anthropics/knowledge-work-plugins, Apache-2.0, pushed 1 Nov 2026.
- Skills in the
marketingfolder:brand-review,campaign-plan,competitive-brief,content-creation,draft-content,email-sequence,performance-reportandseo-audit. - Connectors: the plugin’s
.mcp.jsonpre-configures HubSpot (https://mcp.hubspot.com/anthropic), Ahrefs, Similarweb, Amplitude, Notion, Canva, Figma, Slack, Klaviyo and Supermetrics. Each one needs your own account and OAuth. - Install:
claude plugin marketplace add anthropics/knowledge-work-plugins claude plugin install marketing@knowledge-work-plugins - B2B fit:
campaign-planandcompetitive-briefmap straight onto ABM programme planning.performance-reportwith HubSpot connected gives you a campaign readout drafted from real numbers.
Our full teardown is in Anthropic Marketing plugin review.
2. HubSpot remote MCP server (free with a HubSpot account)
This is the connector most B2B teams will care about, so we checked HubSpot’s own developer page rather than relying on third-party guides.
- Endpoint: HubSpot’s developer documentation gives the server as
https://mcp.hubspot.com. Anthropic’s Marketing and Sales plugins point athttps://mcp.hubspot.com/anthropic. - Read access, per HubSpot: CRM records, activities, content and marketing data, content analytics, conversations, marketing emails, user and account details, and AEO data. Revenue objects (carts, invoices, orders, line items, products, quotes, subscriptions) are labelled beta.
- Write access, per HubSpot: CRM records, activities, content (landing pages, website pages, blog posts), campaigns, marketing email drafts, pipelines, custom properties, quotes (beta), static segments, and AEO prompts and recommendations.
- Auth: OAuth with PKCE. For your own client you create an MCP connector in HubSpot (Development, then MCP Connectors) to get a client ID, secret and redirect URL. The Anthropic plugins handle this through their own connector.
- Permissions: actions follow the signed-in user’s HubSpot permissions. If Sensitive Data is on, HubSpot says activity and conversation data is blocked through the MCP server.
- Some tools need specific tiers, such as Marketing Hub Professional or Enterprise for AEO tools.
Do not confuse this with HubSpot’s developer MCP, which runs locally through the HubSpot CLI and helps you build HubSpot apps and CMS assets. Third-party guides mix the two up. For marketing work you want the remote server.
Practical advice: because the server can write campaigns, static segments and email drafts, start with a HubSpot user whose permissions match what you want Claude to touch. A read-mostly marketing user is a sensible first step.
3. marketingskills by Corey Haines (free, MIT)
- Source: github.com/coreyhaines31/marketingskills, 57,859 stars, pushed 31 Oct 2026.
- B2B-relevant skills in the
skillsfolder:customer-research,competitor-profiling,product-marketing,sales-enablement,revops,co-marketing,events,cold-email,prospecting,social,ad-creative,lead-magnets,attributionandcontent-strategy. - Install:
npx skills add coreyhaines31/marketingskills. - B2B fit: the strongest free library for the work between campaigns: ICP research from interviews, sales one-pagers, co-marketing plans with partners and event follow-up. See our marketingskills review.
4. claude-ads (free, MIT)
- Source: github.com/AgriciDaniel/claude-ads, 10,655 stars, pushed 1 Nov 2026.
- What it does: paid media audits across several ad platforms with a LinkedIn module. ZenABM’s write-up of the repo describes 27 LinkedIn checks covering setup, targeting, creative, lead gen forms and bidding.
- B2B fit: LinkedIn is where most ABM ad budgets go. An audit skill that checks matched-audience setup and lead gen form friction is more useful to a B2B team than another copy generator. More in Claude Code skills for PPC.
5. ZenABM LinkedIn ABM Reporter (free plugin, paid platform)
- Source: github.com/emikor/zenabm-linkedin-abm-reporting, 1 star, pushed 19 Apr 2026, no licence file detected by GitHub.
- What it does, per ZenABM’s guide: weekly, monthly or quarterly LinkedIn ABM reports from ZenABM data, with period-over-period comparison, deal attribution, top engaged accounts and optional PDF export. Trigger is
/abm-report. - Price: ZenABM’s pricing page lists Starter at $59, Growth at $159, Pro at $399 and Agency at $479 per month (checked 2 Nov 2026), with a discount for annual billing.
- Watch out: very new, tiny footprint and tied to one vendor’s API. Fine if you already use ZenABM.
6. ZenABM Outbound Agent (free plugin, paid platform)
- Source: github.com/emikor/zenabm-outbound-agent-plugin, 5 stars, MIT, pushed 12 Apr 2026.
- What it does, per ZenABM: reads engagement signals, finds ICP-matched contacts through Apollo, drafts emails and pushes contacts and copy to Smartlead.
- Watch out: this crosses from marketing into sending. Read the compliance section below before you let anything send automatically.
7. Explorium AgentSource plugin (free plugin, paid data)
- Source: github.com/explorium-ai/agentsource-plugin, 3 stars, pushed 18 Jun 2026.
- What it does: builds target account lists from Explorium’s company data. Vendor claims about speed were not tested here.
- Pricing for the underlying data: not checked for this guide; treat it as pricing not public until you confirm with the vendor.
8. Gingiris B2B growth playbook (free, MIT)
- Source: github.com/Gingiris/gingiris-b2b-growth, 105 stars, pushed 7 May 2026.
- What it is: a B2B SaaS growth playbook (PMF checks, product-led versus sales-led motion, partnerships, affiliates) packaged for AI agents. A related r/ClaudeAI thread titled “I condensed real B2B SaaS growth playbooks into a Claude Skill” describes the goal as behaving “more like a structured operator’s handbook instead of a loose brainstorm.”
- Watch out: the README promotes the author’s paid consulting, and its results claims are the author’s own. Use it for strategy prompts, not as evidence.
9. Salesforce DX MCP (free, Apache-2.0)
- Source: github.com/salesforcecli/mcp, 487 stars, pushed 5 Oct 2026.
- B2B fit: if your marketing data lives in Salesforce rather than HubSpot, this is the official route for Claude to query records and campaign members. It is built for developers first, so ask your Salesforce admin to scope the org and toolsets.
10. Partner plugins in Anthropic’s marketplace (free plugins, paid data)
The same marketplace that ships the Marketing plugin lists vendor plugins B2B teams already pay for, including hubspot-sales, apollo, common-room, leadfeeder, zoominfo, lusha, vibe-prospecting, monday-crm and activecampaign. Install with, for example, claude plugin install leadfeeder@knowledge-work-plugins. The plugins cost nothing; the data follows each vendor’s plan.
Takeaway: pick connectors to match the tools you already pay for, then pick skills.
Free vs paid: comparison table
| Option | Free or paid | Price (checked 2 Nov 2026) | Source | Who it suits |
|---|---|---|---|---|
| Anthropic Marketing plugin | Free | $0 | github.com/anthropics/knowledge-work-plugins | Every B2B team |
| HubSpot remote MCP | Free connector | Your HubSpot plan | developers.hubspot.com | HubSpot shops |
| marketingskills | Free | $0 | github.com/coreyhaines31/marketingskills | Content, PMM, demand gen |
| claude-ads | Free | $0 | github.com/AgriciDaniel/claude-ads | LinkedIn Ads owners |
| ZenABM plugins | Free plugins | ZenABM from $59/month | zenabm.com/pricing | Existing ZenABM users |
| Inflectual bundle | Paid | $167 one-time, 167 skills | inflectual.gumroad.com/l/master-marketing-claude-skills-bundle | Teams that want breadth fast |
| SuperSkills | Paid | $50 | superskills-one.vercel.app | Solo marketers |
| Contra Ultimate Claude SEO & AEO Skills Pack | Paid | $39 shown (vs $79) | Contra listing | B2B teams leaning on organic and AI search |
| Claude Pro | Paid | $20/month ($17/month billed yearly), includes Claude Code | claude.com/pricing | Required to run any of the above |
Is a paid pack worth it for B2B?
Mostly no, at least not first. None of the paid packs above is B2B-specific, and none ships a CRM connector. What you pay for is breadth: dozens of ready-made skills you would otherwise write. If your team has no one willing to edit Markdown files, the Inflectual bundle at $167 one-time is the clearest value of the three. If you do, the free stack plus three custom skills (covered below) will fit your ICP better than any pack written for everyone.
Takeaway: pay for Claude and your data; skills are the cheapest layer.
ABM account research: workflow and example prompt
ABM research with Claude Code works when the skill pulls firmographics and engagement from your CRM, adds public signals, and writes a brief in a fixed format with every claim sourced. Without the CRM layer you get a nicely written company summary that your SDR could have found on the About page.
The setup
Install the Marketing plugin with HubSpot connected, plus marketingskills for customer-research and competitor-profiling. Add your icp.md.
Example prompt
Use the competitive-brief and customer-research skills.
Account: [company domain]. Read the company and its contacts from HubSpot.
Write an account brief using icp.md. Include:
1. Fit score against icp.md, with each criterion marked met, unmet or unknown.
2. Buying committee: contacts we have, roles we are missing.
3. Engagement in the last 90 days from HubSpot (emails, page views, form fills).
4. Three public signals from the last six months (hiring, funding, launches), each with a URL.
5. One recommended angle per persona from messaging.md.
Mark anything you could not verify as UNVERIFIED. Do not guess revenue or headcount.What good output contains
| Section | Pass | Fail |
|---|---|---|
| Fit score | Criteria from your file, each with evidence | A single number with no reasoning |
| Committee map | Real HubSpot contacts plus named gaps | Invented names or titles |
| Signals | Dated, linked | ”Recently expanded” with no source |
| Angle | Tied to a persona’s pain in your messaging | Generic value props |
Scaling to a tier-one list
Run the same prompt across 20 to 50 tier-one accounts and write each brief to /accounts/<domain>.md. Then ask Claude to roll them into a single table sorted by fit and engagement. That table is your ABM planning input, and because each row links to a brief, sales can check the reasoning.
Takeaway: the brief is only as good as the fields your CRM actually holds.
ICP definition and scoring
Use Claude Code to turn closed-won and closed-lost data into an ICP draft, then into a scoring rubric a skill can apply the same way every time. The ICP is the file every other B2B skill reads, so it deserves the most care.
Step 1: pull the evidence
With HubSpot connected, ask Claude to export closed-won and closed-lost deals from the last 12 months with company industry, headcount, region, deal size, cycle length and lost reason. If your CRM fields are messy, say so in the prompt and ask Claude to report fill rates first. A field filled on 30% of deals is not a basis for an ICP.
Step 2: draft the ICP
Use the customer-research and product-marketing skills.
From the attached deal export and the interview notes in /research,
draft icp.md with: firmographic fit, technographic fit, trigger events,
buying committee roles, and disqualifiers.
For each criterion cite the deals or interviews that support it.
List criteria you suspect but cannot support as HYPOTHESES.Step 3: turn it into a scoring rubric
Ask Claude to write a skill, icp-score, that reads icp.md and scores an account on each criterion with a weight you set. Keep the weights in the file, not in Claude’s head, so marketing and sales can argue about the numbers in one place.
What not to do
Do not ask Claude to “define our ICP” from a website and nothing else. It will produce a plausible persona that matches a thousand other SaaS companies. Deeper ICP and persona work for PMMs is in the product marketers guide.
Takeaway: an ICP with citations to real deals beats a polished persona every time.
Case studies: from interview to approved draft
Claude Code is good at turning an interview transcript into a structured case study, and bad at knowing which facts you are allowed to publish. Build the second part into the skill.
A case study skill worth writing
---
name: b2b-case-study
description: Turn a customer interview transcript into a B2B case study draft.
---
## Inputs
- Transcript in /interviews. proof-library.md. messaging.md.
## Rules
- Use only facts and numbers that appear in the transcript or proof-library.md.
- Quote the customer verbatim. Never paraphrase inside quotation marks.
- Any number without a source line goes in a "Needs customer approval" list.
- Note any material connection (discount, free months, reseller deal) in the draft.
## Output
Headline, customer snapshot, challenge, why they chose us, rollout,
results (sourced only), pull quote, approval checklist.Example prompt
Use b2b-case-study on interviews/acme-call.txt.
Also draft a 150-word version for a sales one-pager and three LinkedIn post hooks.What good output contains
A full draft, a short version, social hooks and, most important, an approval checklist that lists every quote and number with the transcript timestamp. Your customer signs off on that list, not on a vague “looks good”.
The compliance limit
In the US, the FTC’s Endorsement Guides apply to customer testimonials in advertising, B2B included. Testimonials must reflect the customer’s honest experience, you cannot imply results that are not typical without support, and material connections need disclosing. The FTC’s rule on consumer reviews and testimonials (in force since October 2024) bans fake or AI-generated testimonials attributed to people who did not give them. Put “never invent a quote” in the skill, not in a style guide nobody opens.
Takeaway: the approval checklist is the most valuable part of the output.
LinkedIn: organic posts and ABM ads
For LinkedIn, split the work: skills write and review posts and ad variants, claude-ads audits the account, and nothing automates activity on LinkedIn itself. LinkedIn’s User Agreement bans scraping and automated activity, so a skill that browses or posts on your behalf puts the account at risk.
Organic: executive and company posts
Use marketingskills social or the Marketing plugin’s draft-content, fed with your messaging.md and a voice file for each executive. A useful prompt:
Turn the attached case study into 5 LinkedIn posts for our CEO.
Each: one idea, under 1,200 characters, no hashtags beyond two,
ends with a question for the comment section. Use only facts from the case study.The full playbook for posts is in Claude Code skills for LinkedIn posts.
Paid: ABM ads
Use ad-creative from marketingskills to draft variants per persona and per funnel stage, then run claude-ads on an export of your LinkedIn Campaign Manager data to check targeting and lead gen form setup. Ask for:
- Ad variants grouped by persona, each tied to one pain from
messaging.md. - A matched-audience plan: which account list feeds which campaign.
- A measurement note: which HubSpot fields will show influenced pipeline.
ZenABM also points to a downloadable LinkedIn Ad Designer skill from Advanced Client with 23 ad patterns; it installs as Claude Project knowledge, not as a Claude Code skill.
Takeaway: let Claude write and audit; keep humans on the LinkedIn buttons.
Sales enablement: one-pagers, talk tracks and follow-ups
Sales enablement is where B2B marketing output gets used or ignored, and Claude Code helps most by producing enablement in the formats reps actually open. The marketingskills sales-enablement skill is the natural starting point.
What to generate
| Asset | Inputs | Output check |
|---|---|---|
| Persona one-pager | icp.md, messaging.md, proof-library.md | One page, one proof point per pain |
| Talk track | Discovery call notes, objections list | Questions first, pitch second |
| Follow-up email kit | Case studies, event notes | Every claim in proof-library.md |
| Objection handling sheet | Lost reasons from HubSpot | Real objections, ranked by frequency |
| Event follow-up | Badge scan list, session topics | Segmented by persona and engagement |
Example prompt
Use sales-enablement. Read closed-lost deals from HubSpot for the last two quarters.
Group the lost reasons, then write an objection sheet for the top five:
the objection in the buyer's words, a reframe, a proof point from proof-library.md,
and a question the rep can ask. Flag objections we have no proof for.That last line is the useful one. The flagged list is your next case study brief.
Where marketing hands off to sales
Battlecards and positioning sit with PMM; sequencing and send tools sit with sales. If you are building cold outreach rather than enablement, the sales teams guide covers ColdIQ, Extruct, Clay and the rest.
Takeaway: generate enablement from lost-deal data, not from your own pitch deck.
CRM MCPs: HubSpot, Salesforce and the rest
Your CRM connector decides what B2B skills can see, so choose it by where your marketing data lives, then lock down permissions before anyone writes. Here is the comparison as of 2 November 2026.
| CRM | Connector | Who maintains it | Marketing data reachable | Notes |
|---|---|---|---|---|
| HubSpot | Remote MCP, mcp.hubspot.com | HubSpot | CRM, campaigns, marketing emails, content, segments | OAuth with PKCE; some tools tier-gated |
| HubSpot | hubspot-sales partner plugin | Listed in Anthropic marketplace | Sales-side CRM | Install via knowledge-work-plugins |
| Salesforce | Salesforce DX MCP | Salesforce | Records, metadata via toolsets | Developer-first; admin should scope it |
| monday CRM | monday-crm partner plugin | Listed in Anthropic marketplace | CRM boards | Check plan limits |
| ActiveCampaign | activecampaign partner plugin | Listed in Anthropic marketplace | Contacts, automations | Check plan limits |
A safe rollout for a marketing team
- Connect with a user that has read access only to marketing objects.
- Run a week of reports and briefs. Check the numbers against HubSpot’s own reports.
- Allow writes to drafts only: marketing email drafts and static segments.
- Never let a skill publish pages or send email without a person approving it.
Data protection
Account briefs pull personal data about named contacts. Under GDPR and UK GDPR you need a lawful basis to process it, and the ICO’s guidance on legitimate interests is the place to start for B2B marketing. Keep briefs in a shared folder your DPO knows about, not in personal laptops. This guide is not legal advice.
Takeaway: start read-only and earn write access.
How to build three custom B2B skills in an afternoon
The highest-value B2B skills are the ones only you can write, because they encode your ICP, your proof and your approval rules. Each one is a short Markdown file.
account-brief: the ABM prompt above, saved as a skill with your output format and the “UNVERIFIED” rule.b2b-case-study: the case study skill above, with your proof library path.claims-check: reads any draft, lists every number, quote and customer name, and checks each againstproof-library.md. Anything missing gets flagged, not removed silently.
Put them in .claude/skills/ inside a shared project repo so the whole team gets the same rules. The walk-through is in how to build a Claude Code skill, and installation help is in how to install Claude Code skills. Not a terminal person? Start with Claude Code skills for non-developers.
Run claims-check on everything before it leaves the building. It is the one skill that protects all the others.
Takeaway: three custom skills beat thirty generic ones for B2B.
Common mistakes B2B teams make with Claude Code skills
Most failures come from missing inputs, not weak skills. Seven to avoid:
- No ICP file. Every skill falls back to generic SaaS personas. Write
icp.mdfirst. - Treating web research as account intelligence. Without CRM engagement data, an account brief is a company summary.
- Letting Claude fill gaps in case studies. If a number is not in the transcript, it is not in the draft.
- Write access on day one. A connector that can edit campaigns and segments should earn that permission.
- Automating LinkedIn activity. It breaks LinkedIn’s terms. Draft with Claude; post by hand or with an approved scheduler.
- Installing every marketplace plugin. Overlapping skills fight over the same trigger words. Keep only what matches your stack.
- Skipping the sales and PMM handoff. Marketing skills that ignore the sales team’s tools produce assets nobody uses. Agree on file formats and where briefs live.
Takeaway: fix inputs and permissions before blaming the model.
What practitioners are saying
We could not fetch reddit.com directly, so the threads below were read through a public subreddit snapshot mirror and are quoted only where we read the text.
- In r/ClaudeAI, a post titled “Built a GTM plugin with 166 marketing skills for Claude Code + /bootstrap command for brand onboarding” (thread) describes a skill set that “interviews you about your brand, audience, and voice” before writing. That onboarding step is the same idea as the context files in this guide.
- The B2B SaaS playbook thread linked in pick 8 drew a sceptical top reply: “Did I just stumble onto LinkedIn?” Fair warning that self-promotional skill launches are common, so judge the files, not the post.
No Quora discussions on this topic turned up in our searches. Treat any time-saving figures you see in vendor blogs about Claude for ABM as vendor claims; we did not find independent tests.
FAQ
What are Claude Code skills for B2B marketing?
Folders with a SKILL.md file that teach Claude a B2B task, such as an account brief, a case study or an objection sheet. Claude loads the skill when your request matches its description.
Is there an official HubSpot MCP server?
Yes. HubSpot documents a remote MCP server at https://mcp.hubspot.com with OAuth and PKCE. It reads and writes CRM records, campaigns, marketing email drafts, content and static segments, subject to the user’s permissions.
How do I connect HubSpot to Claude Code?
The simplest route is installing Anthropic’s Marketing or Sales plugin, which pre-configures https://mcp.hubspot.com/anthropic, and completing OAuth. For your own setup, create an MCP connector in HubSpot to get credentials.
Can Claude Code do account-based marketing?
It can research accounts, score fit, map buying committees and draft per-persona assets. It cannot replace intent data or an ad platform; it reads those through connectors.
What is the best free skill for B2B marketers?
Anthropic’s Marketing plugin plus marketingskills. Both are free and cover planning, research, content and enablement.
Are paid skill packs worth it for B2B?
Rarely as a first purchase. None we checked is B2B-specific. The Inflectual bundle ($167 one-time) is the best breadth buy if no one on your team will write skills.
Can Claude write case studies?
Yes, from transcripts. Build in rules: verbatim quotes only, sourced numbers only and an approval checklist for the customer.
Do FTC rules apply to B2B testimonials?
Yes. The FTC Endorsement Guides cover testimonials in advertising regardless of audience, and the 2024 reviews and testimonials rule bans fake testimonials, including AI-generated ones.
Can Claude Code post to LinkedIn for me?
Do not set it up to. LinkedIn’s User Agreement bans automated activity. Use Claude to draft and review, then post manually or via an approved tool.
How is this different from the sales teams guide?
The sales guide covers prospecting, enrichment, sequencing and call prep. This guide covers the marketing side: ABM programmes, ICP, case studies, LinkedIn, enablement and campaign data in the CRM.
How is this different from the product marketers guide?
The PMM guide goes deep on positioning, launches, pricing and battlecards. Here, PMM output is an input: the ICP and messaging files B2B campaigns read from.
Does Claude Code work with Salesforce?
Yes, through Salesforce’s official DX MCP server. It is developer-oriented, so involve your admin to scope access.
What does Claude Code cost?
It is included with Claude Pro at $20 a month, or $17 a month billed yearly. Higher plans add usage.
Is my CRM data safe with Claude?
The connector acts with your HubSpot user’s permissions. Limit that user, keep Sensitive Data settings on where needed and check your company’s AI and data policies.
Do I need to code?
No. You need to be comfortable typing commands and editing Markdown. Plugins install with two commands.
Can these skills run in Claude Cowork too?
Anthropic’s knowledge-work plugins were built for Cowork and Claude Code alike. Community skills vary, so check each README.
How many skills should a B2B team start with?
One plugin, one library, one CRM connector and three custom skills. Add more only when a real task needs it.

Your first-week plan
Day one: install the Marketing plugin and connect HubSpot with a read-only user. Day two: write icp.md, messaging.md and proof-library.md. Day three: run the account brief prompt on five tier-one accounts and have a rep grade them. Day four: turn the best prompt into an account-brief skill. Day five: add claims-check and run it on everything you shipped that week. By Friday you will know whether skills earn a place in your B2B stack, from your own data rather than from a list.
