Two skills are implemented in this repo as part of the **Command → Agent → Skill** architecture pattern, demonstrating two distinct skill invocation patterns: **agent skills** (preloaded) and **skills** (invoked directly).
|

|
|
## Weather SVG Creator (Skill)
|
|
|
|
**File**: [`.claude/skills/weather-svg-creator/SKILL.md`](../.claude/skills/weather-svg-creator/SKILL.md)
|
|
|
|
```yaml
|
|
---
|
|
name: weather-svg-creator
|
|
description: Creates an SVG weather card showing the current temperature for
|
|
Dubai. Writes the SVG to orchestration-workflow/weather.svg and updates
|
|
orchestration-workflow/output.md.

# Weather SVG Creator Skill
|
|
|
|
This skill creates a visual SVG weather card and writes the output files.
|
|
|
|
## Task
|
|
Create an SVG weather card displaying the temperature for Dubai, UAE,
|
|
and write it along with a summary to output files.
|
|
|
|
## Instructions
|
|
You will receive the temperature value and unit (Celsius or Fahrenheit)
|
|
from the calling context.
|
|
|
|
### 1. Create SVG Weather Card
|
|
Generate a clean SVG weather card...
|
|
|
|
### 2. Write SVG File
|
|
Write the SVG content to `orchestration-workflow/weather.svg`.
|
|
|
|
### 3. Write Output Summary
|
|
Write to `orchestration-workflow/output.md`...
|
|
|
|
...
|
|
```
|
|
|
|
This is a **skill** — invoked directly by the command via the Skill tool. It receives the temperature data from the conversation context and creates the SVG weather card and output summary.

## Weather Fetcher (Agent Skill)
|
|
|
|
**File**: [`.claude/skills/weather-fetcher/SKILL.md`](../.claude/skills/weather-fetcher/SKILL.md)
|
|
|
|
```yaml
|
|
---
|
|
name: weather-fetcher
|
|
description: Instructions for fetching current weather temperature data
|
|
for Dubai, UAE from wttr.in API
|
|
user-invocable: false

# Weather Fetcher Skill
|
|
|
|
This skill provides instructions for fetching current weather data.
|
|
|
|
## Task
|
|
Fetch the current temperature for Dubai, UAE in the requested unit
|
|
(Celsius or Fahrenheit).
|
|
|
|
## Instructions
|
|
1. Fetch Weather Data: Use the WebFetch tool to get current weather data
|
|
- URL: https://wttr.in/Dubai?format=j1
|
|
2. Extract Temperature: From the JSON response, extract temp_C or temp_F
|
|
3. Return Result: Return the temperature value and unit clearly.
|
|
|
|
...
|
|
```
|
|
|
|
This is an **agent skill** — preloaded into the `weather-agent` at startup via the `skills:` frontmatter field. It is not invoked directly; instead, it serves as domain knowledge injected into the agent's context. Note `user-invocable: false` which hides it from the `/` command menu.
|
|

|
|
## Two Skill Patterns
|
|
|
|
| Pattern | Invocation | Example | Key Difference |
|
|
|---------|-----------|---------|----------------|
|
|
| **Skill** | `Skill(skill: "name")` | `weather-svg-creator` | Invoked directly via Skill tool |
|
|
| **Agent Skill** | Preloaded via `skills:` field | `weather-fetcher` | Injected into agent context at startup |
|
|
|
|
---
|
|
|
|
## How to Use
|
|
|
|
**Skill** — invoke directly via slash command:
|
|
```bash
|
|
$ claude
|
|
> /weather-svg-creator
|
|
```
|
|
|
|
**Agent Skill** — not directly invocable (`user-invocable: false`). Preloaded into the agent via `skills:` frontmatter:
|
|
```yaml
|
|
# In .claude/agents/weather-agent.md
|
|
---
|
|
skills:
|
|
- weather-fetcher
|
|
---
|
|
```
|

|
|
|
|
The skills are the final components in the Command → Agent → Skill orchestration pattern. The `weather-fetcher` is preloaded into the `weather-agent` as domain knowledge for API interaction, while the `weather-svg-creator` is invoked directly by the command to transform the fetched data into visual output.
