What are Skills?

Skills are reusable knowledge packages that AI coding agents can discover and use to perform tasks more accurately. Based on Claude Code skills and Agents skills specifications, they provide specialized capabilities that agents can trigger based on the task at hand. Unlike standards (which apply automatically) and commands (which require explicit invocation), skills are agent-discovered—the AI automatically loads relevant skills based on context and triggers defined in the skill.

​
Skill Structure

A skill is a folder containing at minimum a SKILL.md file, plus optional supporting files.

​
Required: SKILL.md

The SKILL.md file contains YAML frontmatter followed by Markdown instructions: 
---
name: 'skill-name'
description: 'Brief description of what this skill does'
---

# Skill Name

Instructions for when and how AI agents should use this skill.
Frontmatter fields:
FieldRequiredDescription
nameYesUnique identifier for the skill
descriptionYesBrief explanation of what the skill does
licenseNoLicense type (e.g., MIT, Apache-2.0)
compatibilityNoWhich AI agents support this skill
allowed-toolsNoList of tools the skill may use
metadataNoAdditional custom metadata

​
Optional Supporting Files

Skills can include additional files alongside SKILL.md:
  • Templates — Boilerplate code, configuration files, or scaffolding
  • Scripts — Automation scripts the skill may reference or execute
  • Resources — Documentation, examples, or reference materials
  • Subdirectories — Organize complex skills with multiple related files
All files in the skill directory are packaged together when you upload the skill.

​
Creating Skills

The easiest way to create a skill is using the /packmind-update-playbook skill in your AI coding assistant. Simply type: 
/packmind-update-playbook create a Packmind skill for <your use case>
The AI agent will guide you through creating a skill with proper structure and documentation. Alternatively, you can create skills manually through the CLI by uploading a skill directory: 
# Create your skill directory with SKILL.md
mkdir my-skill
# Add your SKILL.md and any supporting files
# ...

# Upload to Packmind
packmind-cli playbook add ./my-skill
packmind-cli playbook submit --no-review
Use --no-review to trigger a direct update. Omit --no-review to use the change proposals system and get validation of your changes.
For a complete walkthrough, see Create Your First Skill.

​
Updating Skills

When you upload a skill that already exists in your organization, Packmind automatically handles versioning:
  1. Content comparison — The CLI compares the uploaded content against the latest version
  2. New version created — If any content differs (changes to SKILL.md, new files, modified scripts, or updated assets), a new version is created
  3. No duplicate versions — If the content is identical to the current version, no new version is created
To update an existing skill, simply upload it again: 
packmind-cli playbook add ./my-skill
packmind-cli playbook submit --no-review
Use --no-review to trigger a direct update. Omit --no-review to use the change proposals system and get validation of your changes.

​
Viewing Version History

You can view all versions of a skill in the Packmind web app:
  1. Navigate to Skills in the main menu
  2. Click on the skill you want to inspect
  3. View the Version history section to see all versions
Each version includes a timestamp, allowing you to track when changes were made.

​
Deleting Skills

You can delete skills that are no longer needed through the Packmind web app.

​
Delete a Single Skill

  1. Navigate to Skills in the main menu
  2. Click on the skill you want to delete
  3. Click the Delete button
  4. Confirm the deletion in the dialog

​
Delete Multiple Skills

To delete multiple skills at once:
  1. Navigate to Skills in the main menu
  2. Select the skills you want to delete using the checkboxes
  3. Click Delete selected
  4. Confirm the batch deletion in the dialog
Impact on packages — When you delete a skill that’s included in one or more packages, those packages will be updated. You’ll need to redistribute the affected packages to remove the skill from your repositories.

​
Viewing Skills

Access your skills through the Packmind web app:
  1. Navigate to Skills in the main menu
  2. Browse the list of available skills
  3. Click a skill to view its details
The skill details view shows:
  • Description — What the skill does
  • Files — All files included in the skill
  • Version history — Track changes over time
  • Packages — Which packages include this skill

​
Skills in Packages

Skills can be added to packages alongside commands and standards. To add a skill to a package:
  1. Go to Packages in the web app
  2. Edit an existing package or create a new one
  3. Select skills to include
  4. Save the package
When you distribute a package, all included skills are deployed together with your other artifacts.
Default skills included — When packages are distributed (via the web app push strategy or CLI install), Packmind’s default skills are automatically included. This ensures the packmind-update-playbook skill is always available for creating and updating playbook artifacts with AI assistance.

​
Where Skills Appear After Distribution

After distributing a package containing skills, they appear in specific locations based on the AI assistant:
AI AssistantWhere Skills Appear
GitHub Copilot.github/skills/{skill-slug}/SKILL.md
Claude Code.claude/skills/{skill-slug}/SKILL.md
Cursor.cursor/skills/{skill-slug}/SKILL.md
GitLab Duo.gitlab/duo/skills/{skill-slug}/SKILL.md
OpenCode.opencode/skills/{skill-slug}/SKILL.md
Codex.agents/skills/{skill-slug}/SKILL.md
The source files are always stored in .packmind/skills/ regardless of which AI assistants are enabled.
Skills are currently available for Claude Code, Cursor, GitHub Copilot, Codex, OpenCode and GitLab Duo. Other AI assistants do not support skill rendering.
