The LinkedIn agent skill

Eleven Claude skills that run a LinkedIn account. Free, MIT, no signup, no API key, nothing to connect.

One of them writes your posts off 21 hook formulas. One comments on other people's posts. One handles the replies under yours. One scores your profile out of 100 and rewrites what lost points. One plans the week: what to post, when, and who to engage with.

And one is the humanizer, which is the reason the rest are usable. It strips the em dashes, the slop vocabulary and the invisible watermark characters out of a draft, then scores what is left against a five-check detection panel before you ever see it.

Nothing gets posted until you say yes. These skills write. You post.

Install

Paste this into Claude:

https://github.com/Jakeschincariol/linkedin-agent-skill

Install this skill, then confirm /li-post works.

Or do it yourself, in Claude Code:

git clone https://github.com/Jakeschincariol/linkedin-agent-skill.git
cp -r linkedin-agent-skill/skills/li-* ~/.claude/skills/

Or as a plugin:

/plugin marketplace add Jakeschincariol/linkedin-agent-skill
/plugin install linkedin-agent

Project-local instead of global: copy the same folders into your repo's .claude/skills/. No Claude Code at all? Paste any single SKILL.md at the top of a chat and it runs as a mode - you lose the two Python tools, which is most of the point of /li-human, but the rest works.

Then spend ten minutes on templates/voice.md. Copy it to ~/.claude/linkedin/voice.md and fill it in, or paste three of your own posts into Claude and say "write my voice.md from these". Every skill reads that file. Skip it and everything comes out sounding like everyone else.

The eleven

command	what it does
/li-post	One idea into a post. Three hook options from 21 formulas, one full draft, humanized before you see it.
/li-comment	Comments on other people's posts. Nine types, picked by what the post actually is. Never "Great post!".
/li-reply	The thread under your own post. Sorts every comment into lead / substance / peer / support / noise, then writes in that order.
/li-profile	Scores your profile against a 12-part rubric out of 100, then rewrites in fix-first order.
/li-plan	The week. What to post, when to post it, and the 10 people to engage with. Writes ~/.claude/linkedin/plan.md.
/li-human	The humanizer. Two scripts that actually run. See below.
/li-carousel	Document posts. Slide-by-slide copy, the cover that earns the swipe, and the PDF to upload.
/li-repurpose	One video, newsletter or transcript into a week of posts that each stand alone.
/li-dm	The 200-character invite note, the first message, and the two follow-ups. Two.
/li-inbox	Triages the inbox into lead / recruiter / peer / ask / spam, and tells you which tell gave the sequence away.
/li-audit	Post-mortem on what you have already published. Ranks by engagement rate and reach multiple, not impressions.

The humanizer

/li-human ships two Python scripts with no dependencies. They run on your machine, on your text, and nothing is uploaded.

python3 humanize.py draft.txt --report      # clean it, show every change
python3 detect.py draft.txt                  # score it, five checks
python3 detect.py before.txt after.txt       # prove the delta
