1# Skill Creator

3Create new skills and iteratively improve them inside this SkillPack. Determine where the user is in the create → draft → test → improve cycle and help them move forward.
4
5## Pack-specific rules
6
7All skills live under `{{SKILLS_PATH}}/<skill-name>/SKILL.md` and config is at `{{PACK_CONFIG_PATH}}`. These paths override any generic advice. Never create skills in the current workspace directory — always use `{{SKILLS_PATH}}`.
8
9## Creating a skill
10
11### Capture intent
12
13Extract answers from the current conversation first, then fill gaps with targeted questions. Confirm before writing the first draft:
14
151. What should this skill enable the model to do?
162. When should this skill trigger?
173. What output should it produce?
184. Does the user want a lightweight draft, or a tested and iterated skill?
19
20Clarify edge cases, input/output formats, success criteria, and dependencies as needed before writing test prompts.
21
22### Write the skill
23
24Create the skill at `{{SKILLS_PATH}}/<skill-name>/SKILL.md`. Example template:
25
26```yaml
27---
28name: example-skill
29description: "Analyze competitor pricing pages and generate a comparison matrix. Use when the user wants to benchmark pricing tiers, feature gaps, or positioning against specific competitors."
30---
31
32# Example Skill
33
34## Workflow
35
361. Collect the target URLs from the user.
372. Extract pricing tiers, features, and limits from each page.
383. Generate a comparison matrix as a markdown table.
