SkillSeed

Build Agent Skills that work across Claude Code, Codex, Cursor, and more — SkillSeed scaffolds them, validates they trigger, and learns from every one.

SkillSeed is a meta-skill (skillseed) that scaffolds Agent Skills end-to-end. It’s more than a file generator — it’s a skill-writing coach that checks whether your skill will actually trigger, validates it against the format spec, and learns from every skill you create via a built-in experience log. Generated skills follow the open standard, so the same skill works in Claude Code, Codex, Cursor, Gemini CLI, and any compatible tool.

Why SkillSeed?

Most agents can already write a SKILL.md on their own. So SkillSeed earns its place by doing what raw generation doesn’t:

• Trigger validation — the #1 skill failure mode is “written fine, but the agent never auto-triggers it”. SkillSeed forces 6 boundary cases (3 should-trigger + 3 should-not-trigger) and tightens the description until they pass.
• Conformance self-check — no silent failures from name casing, oversized descriptions, references that chain-load each other, or 500+ line SKILL.md.
• Self-improving experience log — every skill you create appends a lesson to lessons.md; next time, SkillSeed reads it first. The rules never drift; only the memory grows.
• Cross-tool by default — one skill, many agents. Install the same skill to Claude Code, Codex, or Cursor with a single flag.
• Living examples — skillseed itself is a spec-compliant skill; processing-pdfs is one it generated. Read them to learn the craft.

What you can do with it

• Scaffold a new skill in minutes — /skillseed ""
• Learn skill best practices — read skill-anatomy.md + study the two example skills
• Use as your skill repo starting point — fork, drop your skills into skills/, install with the script
• Target any agent — install the same skill to Claude Code, Codex, or Cursor (or all of them)

Quick start

git clone https://github.com/ht426/skillseed.git SkillSeed && cd SkillSeed

# Install skillseed into a tool (default: claude)
bash scripts/install-skill.sh skillseed --tool claude --project
# same skill, other tools:
bash scripts/install-skill.sh skillseed --tool codex --user
bash scripts/install-skill.sh skillseed --tool cursor --project

# restart the target tool once (first time creates its skills dir), then:
/skillseed processing-pdfs "extract tables and text from PDF invoices"

SkillSeed（中文文档）

一个 Agent Skills 仓库: 基于 Agent Skills 开放标准, 生成的 skill 兼容 Claude Code、Codex、Cursor、Gemini CLI 等工具。内置 skillseed —— 一个帮你创建其他 skill 的 meta-skill。

为什么用 SkillSeed（核心优势）

多数 agent 原生就能生成 SKILL.md。所以 SkillSeed 不靠"生成文件"取胜, 而靠这些原生做不到的增值:
