# Custom Skills in Breeze Assistant

> **Tip**
>
> TL;DR: HubSpot Breeze Assistant now supports custom skills, reusable sets of markdown instructions you create once and invoke by slash-command in any Breeze conversation. Available to all hubs and all tiers.

## What This Update Actually Is

Custom skills are reusable instruction sets you build inside the Breeze Assistant side panel. Each skill holds a set of markdown instructions that tell Breeze exactly how to handle a specific task or context unique to your organization.

Once you save a skill, you invoke it with a slash-command in your prompt. Type the skill name, and Breeze runs those instructions as part of its response. No copying and pasting. No re-typing context from scratch.

There are two ways to create a skill. You can describe what you want in conversation and let Breeze draft the skill for you. Or you can import an existing markdown file directly. Skills follow the Agent Skills spec, which means anything you've written for other HubSpot agents can be ported into Breeze without starting over.

Two limits worth knowing upfront: skills currently support markdown instructions only. Tools, scripts, and external data sources aren't supported yet. And Breeze won't select a skill automatically. You have to invoke it explicitly every time.

## Why HubSpot Shipped This

Here's the pattern we've seen across portals: a marketer opens Breeze, types three paragraphs of company background, lists the tone guidelines, explains the ICP, and then asks the actual question. The next session? They do it all again.

Breeze already pulls context from your portal data, your memories, and past conversations. But those sources are passive. They surface what Breeze infers. Custom skills add an active, explicit layer. You decide what gets captured and exactly how Breeze should use it.

The internal frustration this solves is real. Humans who use AI daily hit a wall when the tool keeps treating every session like a first conversation. Custom skills turn Breeze from a smart stranger into something much closer to a briefed collaborator.

## How to Use It Step by Step

1. Open the Breeze Assistant side panel in your HubSpot portal.
2. Navigate to the skills management section inside the panel.
3. Create a skill conversationally: describe the task or context you want to capture and let Breeze generate the skill draft for you. Review it, edit as needed, and save.
4. Or import a skill: upload a markdown file you've already written for another agent or use case. Breeze accepts any file built to the Agent Skills spec.
5. Name the skill clearly. Short, action-oriented names make slash-commands easier to remember. Think /icp-brief or /email-tone, not /skill1.
6. In any Breeze conversation, type the slash-command followed by your actual prompt. Breeze runs the skill instructions alongside your request and returns a response that reflects both.
7. Manage, edit, or delete skills in the same panel whenever your business context changes. Update the skill once; every future invocation picks up the new instructions.

## What It Touches in Your HubSpot Strategy

Custom skills live in the Breeze Assistant side panel, but the ripple goes further than one tool.

For marketing teams, skills mean consistent brand voice and ICP framing across every piece of Breeze-assisted content, without relying on each person to remember the guidelines. One skill, one source of truth.

For sales teams, a skill can hold your qualification framework, your common objection responses, or your deal memo format. Reps invoke it when drafting follow-up emails or prepping for calls, and every output reflects the process you've actually defined.

For RevOps and operations leaders, this connects directly to the broader push toward structured, repeatable AI use inside HubSpot. Skills are essentially SOPs that Breeze can execute. If you've been thinking about how to standardize AI-assisted work across your team, this is a concrete place to start.

Custom skills also pair well with the recent [custom agent plans HubSpot shipped based on real portal usage](https://www.sidekickstrategies.com/hubspot-updates/hubspot-custom-agent-plans-based-on-team-usage). Where agent plans map out what your agents should do, custom skills give the humans on your team a parallel layer of reusable, structured prompting.

> **Key takeaway:** Custom skills are portable. If your team or agency has already built skills for other HubSpot agents, those files transfer directly into Breeze. You don't rebuild from scratch for every tool.

The portability point matters more than it might seem at first. As HubSpot expands its agent ecosystem, skills authored once can move across agents. That means the investment you make today in writing good skills compounds over time.

That's the core idea behind human-centered AI use: humans set the trajectory, AI adds the speed. If you want to go deeper on that principle, our piece on [trajectory before speed in marketing and sales AI](https://www.sidekickstrategies.com/blog/trajectory-before-speed-human-centered-ai) lays it out in full.

> **Key takeaway:** Skills must be invoked explicitly with a slash-command. Breeze won't auto-select them. This is a feature, not a gap. Explicit invocation keeps humans in control of when and how business context shapes the AI's output.

## Who Should Care Most

This update is relevant across every hub and tier, but some roles will get outsized value right away.

- Content and marketing managers who use Breeze daily for copy, emails, or social content. Skills lock in brand voice and audience framing so every output starts from the same foundation.
- Sales enablement leads who want reps using a consistent framework for outreach, follow-up, or deal notes without writing a training doc nobody reads.
- RevOps and operations professionals building repeatable processes on top of HubSpot's AI layer. Skills let you encode process logic in a place where humans on your team will actually use it.
- HubSpot agencies and partners managing multiple portals. Because skills follow the Agent Skills spec, you can develop a library of reusable skills and deploy them across clients without rebuilding for each portal.
- Small and mid-sized business owners who are the primary Breeze user in their portal. Skills eliminate the overhead of re-explaining your business every session, which makes AI assistance actually sustainable at a small team's pace.

## George's Take

I've been watching teams lose hours to what I call the context tax: the time you spend re-explaining your business to an AI tool before it can help you. Custom skills are HubSpot's answer to that problem, and it's the right answer. When humans can capture their knowledge, their process, and their context in a reusable form that an AI can actually run, that's when AI starts feeling less like a novelty and more like infrastructure. Build your first three skills around the tasks you repeat most. Keep the instructions tight. Invoke them consistently. That's when this feature starts compounding.

> The context tax is real. Every time a human re-explains their business to an AI from scratch, that's time and energy that should have gone into the actual work. Custom skills are how you stop paying that tax.

## Frequently Asked Questions

### What are custom skills in HubSpot Breeze Assistant?

Custom skills are reusable sets of markdown instructions you create inside the Breeze Assistant side panel. You invoke them by name using a slash-command in any Breeze conversation. They let you capture business-specific context and repeated task instructions once and reuse them across every session without re-typing.

### How do I create a custom skill in Breeze Assistant?

There are two ways. First, describe what you want conversationally and let Breeze draft the skill for you. Second, import an existing markdown file built to the Agent Skills spec. Both options are accessible from the Breeze Assistant side panel inside your HubSpot portal.

### Do Breeze custom skills work across all HubSpot tiers?

Yes. Custom skills in Breeze Assistant are available to all hubs and all tiers, including Free and Starter. Any HubSpot portal can create, import, and manage skills in the Breeze Assistant side panel.

### Can custom skills run tools or pull in external data?

Not yet. As of October 2026, custom skills only support markdown instructions. Tools, scripts, and external data sources aren't supported in this release. HubSpot's release notes indicate this is a current limitation, not a permanent constraint.

### Will Breeze automatically select a custom skill during a conversation?

No. Breeze won't auto-select skills. You must invoke a skill explicitly by using its slash-command in your prompt. This keeps humans in control of when and how skill instructions shape the AI's output, which is by design.

### Can I use skills I built for other HubSpot agents inside Breeze Assistant?

Yes. Custom skills in Breeze follow the Agent Skills spec, the same standard used for other HubSpot agents. Any skill file you've already authored for another agent can be imported directly into Breeze without rewriting it.
