What is the best agent skill stack for content and social posts?
Reviewed . Scores and counts come from the directory snapshot of .
Short answer: ghostwriter from mblode/agent-skills (87/100) drafts, rewrites and critiques posts, messages and docs in your voice with the machine tells stripped, and line-editing from danjdewhurst/story-skills (90/100) polishes the result at the sentence level. linkedin-profile-optimizer from sergebulaev/linkedin-skills (94/100) is the highest-scoring skill in the set and fixes the profile every post points back to. Add contagious for the angle, content-strategy for the plan, and co-marketing for distribution partners.

How to use it
- Plan with content-strategy. It decides what to create and which topics to cover, with topic clusters, content pillars and an editorial calendar. Decide the topics for the quarter before you write a line, or the posts will chase whatever happened that morning.
- Shape each piece with contagious. It works through the STEPPS framework: Social Currency, Triggers, Emotion, Public, Practical Value and Stories. Pick one or two per post. A post that tries all six has no point.
- Draft with ghostwriter. It writes, rewrites and critiques in your voice or the company's, with machine tells stripped. Ask it to critique your own draft before you ask it to write one; the critique is often the more useful output. Give it your best three posts as the voice sample, not your last three.
- Polish with line-editing: copyediting, proofreading, tightening sentences, and grammar and punctuation checks. This is the pass that separates a post that reads like a person from one that reads like a template.
- Fix the destination with linkedin-profile-optimizer. Every post sends people to a profile, and it audits and rewrites the whole thing: headline, About, Featured, banner, photo, Experience metrics, skills, custom URL and recommendations.
- Find reach with co-marketing. It finds partners, plans joint campaigns and brainstorms cross-promotion and integration marketing, which is the distribution most solo content plans forget.

What to check before you install
- Licenses: all six are MIT. Confirm the license file in each repository anyway; a directory field is a record, not a legal review.
- Services: none of the six summaries names an outside API. The LinkedIn changes are ones you apply yourself in your own account. The voice skills work on what you give them, so keep real samples of your writing on hand.
- Read each SKILL.md before you enable it. The directory has not security scanned any skill, and a writing skill is still instructions you are handing to an agent with access to your files.
FAQ
Will the posts sound like AI wrote them?
ghostwriter's summary says it strips machine tells, and line-editing tightens what remains. Neither replaces reading the post aloud before it goes out. If a sentence is one you would not say to a customer across a table, cut it. The machine tells are the easy part; the hard part is having something to say.
Do these skills work in Codex and Cursor?
Yes. All six use the Agent Skills format, so the same folder works in Claude Code, Codex, Cursor and any other agent that reads a SKILL.md. The skills CLI installs for each of them, and every skill page in the directory shows the commands.
Do any of these skills publish the posts?
No. None of the six summaries mentions scheduling or posting; they produce text. Publish through whatever tool you already use, and keep the drafts in your repository so you have a record of what went out and what it did. content-strategy, with about 169,000 installs recorded by skills.sh, is the most installed skill here, and co-marketing follows at about 84,000. That says something about where the hard part of content really is: not the writing, but deciding what to say and getting it seen.
