meta-creator

A Kiro agent skill for creating and iteratively improving agent skills and custom agents.

Architecture

Workflow

What It Does

• Creates new SKILL.md files with proper frontmatter and instructions
• Creates evals/evals.json with at least 3 eval cases
• Creates or updates Kiro custom agent configs (.kiro/agents/<name>.json)
• Runs eval-driven iteration: analyzes failures and improves skills

When to Use

Trigger phrases: "create a skill", "make a skill", "new skill", "update skill", "improve skill", "create an agent", "new agent", "update agent", "创建skill", "创建技能", "新建skill", "更新skill", "优化skill", "创建agent", "新建agent", "更新agent"

Workflow Steps

1. Gather requirements — what the skill does, example tasks, environment needs
2. Create SKILL.md — frontmatter (name, description) + step-by-step instructions
3. Create evals/evals.json — happy path, variation, and edge case
4. Iterate — if eval results are provided, fix instruction gaps and update assertions
5. Create agent (optional) — .kiro/agents/<name>.json with prompt, tools, and skill references

Outputs

skills/<name>/SKILL.md	Skill instructions
skills/<name>/evals/evals.json	Eval cases
.kiro/agents/<name>.json	Agent config (only if requested)
