Skills

Create reusable instruction packs that AI Agents load on demand.

Skills are reusable, versioned instruction packs for AI Agents. A skill contains instructions and optional supporting files, such as references, templates, and scripts.

Attach skills to an AI Agent Node. The agent sees each skill's name and description first. It loads the full instructions only when a task matches. This keeps the agent focused while making specialized playbooks available when needed.

Skills are shared across your organization. Everyone can use a skill. Its creator and organization admins can edit it.

Browse skills

Open Skills from the dashboard sidebar. The page lists every skill available to your organization.

From the Skills page, you can:

Control	What it does
New skill	Create a skill in the editor.
Import → Upload folder or Upload .zip	Import a bundle containing SKILL.md.
StackAI or Custom filters	Show built-in skills or organization skills.
All authors	Filter skills by creator.
Card menu → View, Edit, or Delete	Open, update, or remove a skill.

Each skill card shows its author and last-updated date.

Create a skill

1

Open the editor

On the Skills page, select New skill.

2

Define the skill

Complete the required fields:

Field	Requirements
Name	Use 1–64 characters. The agent sees this name in its skill list.
Description	Describe what it does and when to use it. The agent uses this text to decide whether to load the skill.
Instructions	Add the full playbook. Markdown is supported.

Use concrete trigger phrases in the description. For example:

Draft a release announcement from merged PRs. Use when asked to announce a release.

3

Add supporting files and integrations

Under Supporting files, select New file to author a Markdown file. Select Upload files to add references, templates, or scripts.

You can organize files into folders. Select Add integrations to attach required apps and tools.

Skills with supporting files need the Terminal tool. Accept Add tool when prompted. The agent uses Terminal to read bundled files in its code sandbox.

4

Save the skill

Select Save. StackAI publishes version 1 immediately.

Attach a skill to an agent

Skills are available from an AI Agent (LLM) node in the workflow builder.

1. Open the node settings and select the Skills dropdown.

2. Select one or more skills.

3. Complete the setup flow for skills that include tools.

The dropdown also lets you:

• Select Add new skill to create a skill inline.

• Select Explore skills to open the Skills page.

• Select Manage AI agent's skills to review or remove attached skills.

At runtime, StackAI adds an available-skills list and a Get Skill tool. The agent loads matching instructions on demand. Supporting files are mounted in its code sandbox.

Import and export

Export a skill from the editor as an Agent Skills-compatible .zip. The archive contains {skill-name}/SKILL.md and any supporting files.

Import a skill from the Skills page using Upload folder or Upload .zip. The open format supports clean round trips with Claude and compatible tools.

Built-in skills

StackAI provides these read-only skills for every organization:

Skill	What it does
Deep Researcher	Runs multi-source research and produces a cited answer.
Meeting Summarizer	Turns a meeting transcript into a structured summary with action items.

To customize a built-in skill, export it and import your own copy.

Limits

Limit	Value
Total bundle size	30 MB
Single file size	10 MB
Files per skill	500
Name	1–64 characters
Description	Up to 1,024 characters

Best practices

• Write descriptions as what it does + when to use it. This determines whether the agent loads the skill.

• Expect every edit to republish. Use Version history to restore a prior version.

• Add Terminal whenever a skill includes supporting files.
