skill-creator: your own blog skill pack

Running a blog or a channel and drowning in routine — posts, repackaging, replying to leads? Build your own "skill pack" for Claude — skill-creator helps you make one that actually works 🔥

What it does

Anthropic's official "skill wizard": it helps you create a new skill, edit an existing one and measure its quality (eval). It works as a loop: clarifies what the skill should do and when it should fire → drafts the instructions → runs with and without the skill (baseline) → quantitative success asserts → shows the results in an interactive viewer → refines from feedback. The emphasis is on the "why" rather than rigid rules: it keeps the prompt compact and generalizes the skill beyond the specific examples.

Worth knowing: a skill is just a folder with a SKILL.md file. So a "blog skill pack" is a set of several such SKILL.md files that you assemble around your own tasks. skill-creator exists to assemble them properly and to verify they help rather than just sound clever.

The blog skill pack

Anthropic ships no official "blog pack" — that's exactly what you build with skill-creator. A working trio:

1. Content automation — the skill holds your tone of voice, your rubrics and the post format (hook → value → CTA), generates drafts and an idea bank from a brief or a link.
2. Growth / reach — the skill repackages a single post for different platforms, throws out headline and hook variants, assembles the SEO/hashtag wrapper.
3. Lead handling — the skill triages inbound from DMs/comments/forms: qualifies against your criteria, replies by script and drops the lead into a spreadsheet/CRM.

The value of skill-creator here isn't "write it nicely" — it's running the A/B (with the skill and without) and showing where it actually improved the result.

How to set it up

It ships in the example-skills set:

/plugin marketplace add anthropics/skills
/plugin install example-skills@anthropic-agent-skills

Or copy the skill-creator/ folder from the repo into ~/.claude/skills/. In Claude Code the skill is also available directly as skill-creator (anthropic-skills).

When to pick it

• A repeating manual pattern (a post, distribution, a reply to a lead) is ready to be packaged into a skill — and done right.
• The skill already exists but triggers poorly or is bloated — the description and the body need optimizing.
• You want an honest measurement: does the skill help at all (an A/B run with evals).

Example

Say "build me a skill for post drafts in my style" — skill-creator will clarify the rubrics and tone of voice, sketch out SKILL.md, run test briefs with and without the skill, show where the output got better, and polish the description for auto-triggering. Then you add the growth and lead skills through the same loop — and you have your own blog pack.

Gotchas

• This is a build tool, not a ready-made content factory: you still describe the blog skills yourself, skill-creator only makes them reliable.
• A skill ≠ publishing: posting to social networks and CRM are wired up separately (via MCP/integrations), the skill itself only prepares the text and the decision.
• Auto-triggering only fires if the description contains words you actually say — otherwise the skill won't be picked up.
• Evals cost tokens and time: on a simple skill an A/B run can be overkill.
• The basics of the skill format are in the Agent Skills (how they work) card; publishing and lead handling belong to separate MCP connectors.

🤖 Prompt accelerator

"You are skill-creator. Help me assemble a skill pack for running my blog about on . I need three skills: (1) post drafts in my tone of voice and rubrics , format hook→value→CTA; (2) repackaging a post for + headline variants; (3) triaging inbound leads by the criteria with a scripted reply. For each: clarify the triggers, sketch SKILL.md, run a baseline (with and without the skill) on 3–5 of my examples and show where it got better. Start with the first one."
