## Skills vs Agents vs Instructions
- Skills are reusable workflows you load for specific tasks.
- Agents are full modes/personas that control behavior end-to-end.
- Instructions are always-on repo rules that auto-apply by file pattern.

## What Skills Are
Skills are reusable instructions and workflows that guide the assistant through specialized tasks.

## When To Use A Skill
- The task has a repeatable workflow.
- You want consistent structure and outputs.
- The task spans multiple files or steps.

## Skills Directory
Store skills in the team-approved skills directory for your environment. If you do not know the location, ask your team lead or check your internal setup docs.

### Example Question To Ask
Example prompt:
```text
Where is the approved skills directory for our team, and how do I add a new skill?
```

## Skills Governance And Sync
To keep skills consistent across teams, use a central skills registry plus a per-project manifest. Avoid copying skills into every repo unless the skill is tightly coupled to the project.

### Recommended Pattern
- Central skills registry repo (single source of truth)
- Project-level manifest that pins required skills and versions
- Sync script that pulls the approved set to each developer's laptop
- Agents.md points to the manifest and sync command

### Project Manifest Example
Use a small manifest to declare the approved skills and versions for the project:

```yaml
version: 1
registry: git@<host>:org/mobile-ai-skills.git
skills:
	- name: swiftui-expert-skill
		version: 1.2.0
	- name: onboarding-cro
		version: 1.0.0
```

### Sync Workflow
1. Run the sync script.
2. The script pulls the registry and copies required skills to your local skills directory.
3. Restart your editor if required.

### Example Sync Command
```bash
./scripts/sync-skills.sh
```

## How to Download Existing Skills
1. Locate the skill in the team or org repository.
2. Add the skill to your local skills directory following team guidance.
3. Restart the editor or chat if required so the skill is recognized.

## How to Enable or Configure Skills
- Follow the instructions provided in each skill's README or SKILL file.
- Some skills require additional setup, such as environment variables or tools.

## How To Connect Skills
1. State the primary skill you want to use.
2. Provide the inputs that skill expects.
3. If needed, add a secondary skill and explain the handoff.

### Example Skill Request
Example prompt:
```text
Use swiftui-expert-skill to review this view for best practices. Then use webapp-testing to validate the web flow.
```

## Central Assets Repo (Recommended)
Do not list every skill in this guide. Instead, point readers to a single repo that contains the approved agents, skills, and instructions they can download.

### What To Include In The Assets Repo
- Agents (agent prompt files)
- Skills (SKILL files and any required setup)
- Instructions (repo-level and editor-level guidance)
- A short README with install and update steps

### Link To The Assets Repo
- Repo: (link)
