Install it

View source on GitHub ↗

git clone --depth 1 --filter=blob:none --sparse https://github.com/edupegoretti/fluidz-skills.git /tmp/fluidz-skills
git -C /tmp/fluidz-skills sparse-checkout set "skills/capabilities/linkedin-commenter-extractor"

Picked up without a restart. A project skill of the same name is shadowed by your personal one. For one repository only, swap ~/.claude/skills for .claude/skills. Claude Code docs ↗

The folder is the same in every client that implements the format — 46 of them — so if yours is not above, only the destination changes.

Before you install: this skill will not complete its job on a bare agent. It needs APIFY_API_TOKEN, which you have to obtain separately.

Quick Start

Requires requests and APIFY_API_TOKEN environment variable.

# Extract commenters from a single post
python3 skills/linkedin-commenter-extractor/scripts/extract_commenters.py \
  --post-url "https://www.linkedin.com/posts/someone_topic-activity-123456789"

# Multiple posts

How It Works

Takes one or more LinkedIn post URLs
Calls the harvestapi~linkedin-post-comments Apify actor (no cookies needed)
Extracts commenter name, headline (title + company), LinkedIn profile URL, and comment text
Parses headline into separate title and company fields where possible
Optionally deduplicates across multiple posts by LinkedIn profile URL
