LinkedIn Post Generator

Generate LinkedIn posts from shared source material, written in each user's personal style.

How It Works

1. Personal style profile — stored locally at ~/.config/casper/linkedin-style.md (never committed)
2. Source config — stored locally at ~/.config/casper/linkedin-sources.md (never committed)
3. Shared source material — meeting transcripts, Slack dumps, docs in source-material/
4. Prompt template — extraction rules, voice guidelines, few-shot examples in references/prompt-template.md

First Run: Style Setup

Check if ~/.config/casper/linkedin-style.md exists.

If it does NOT exist, run the style setup flow:

1. Say: "Welcome to the LinkedIn Post Generator! Before we start, I need to understand your writing style."
2. Say: "Share 3 LinkedIn posts that match the style you want. You can either paste the post links (e.g. https://linkedin.com/posts/...) or paste the text directly."
3. Wait for the user to provide 3 posts
4. If the user provides LinkedIn URLs, fetch the post content using the apify-scrapers skill:

   python ${CLAUDE_PLUGIN_ROOT}/skills/apify-scrapers/scripts/scrape_linkedin_posts.py search "{url}" --max-posts 1
   

   Extract the post text from the JSON output. If a URL fails to fetch, ask the user to paste that post's text instead.
5. Analyze the posts for: tone, sentence length, vocabulary, formatting habits, hook style, CTA style, use of questions, paragraph length, overall energy
6. Create ~/.config/casper/ directory if it doesn't exist
7. Save the analysis to ~/.config/casper/linkedin-style.md using this format:

# LinkedIn Style Profile
Generated: [date]

## Tone
[analysis]

## Structure Patterns
[paragraph length, line breaks, formatting habits]

## Hook Style
[how they open posts]

## CTA / Closing Style
[how they end posts — questions, challenges, etc.]

## Vocabulary & Phrases
[distinctive phrases, word choices, energy level]

## Sample Posts
[the 3 original posts, for reference]

8. Confirm: "Got it! Your style profile is saved. You can update it anytime with /casper:generate-linkedin-post --setup"

First Run: Source Material Check

After style setup completes (or if style exists but source-material/ is empty), check for source material:

1. Check if source-material/ contains any .md files besides README.md
2. If empty, guide the user:
   • Say: "You don't have any source material yet. I need content to generate posts from — meeting transcripts, notes, Slack conversations, etc."
   • Present options:
     • "Connect integrations" — run the --setup-sources flow to configure Fireflies, Slack, or Google Drive auto-pulling
     • "Paste something manually" — run the --add-source flow to let the user paste a transcript, notes, or other content
   • Wait for user choice and proceed with the selected flow
3. If source material exists, proceed with generation

Normal Run: Post Generation

If style config exists and source material is available, proceed with generation:

1. Read ~/.config/casper/linkedin-style.md
2. Read ALL files in ${CLAUDE_PLUGIN_ROOT}/skills/linkedin-post-generator/source-material/ (excluding README.md)
3. Read ${CLAUDE_PLUGIN_ROOT}/skills/linkedin-post-generator/references/prompt-template.md
4. Apply the confidentiality rules from the prompt template (no financials, no client names, no pipeline, no team member names)
5. Generate 2-4 post options based on the source material, written in the user's personal style
6. Present them in a clean, copy-paste-ready format

Flag Details

--setup-sources

Interactive setup for automatic source pulling. Read references/source-integrations.md for full details.

1. Ask: "What's your work email address? This is used to filter transcripts to only meetings you attended."
   • Save as user_email in the config
2. Ask: "Which sources do you want to connect?" Present options:
   • Fireflies.ai — pulls meeting transcripts (needs FIREFLIES_API_KEY env var)
   • Slack — pulls messages from channels (needs SLACK_BOT_TOKEN env var)
   • Google Drive — pulls docs and transcripts (needs OAuth setup via google-workspace skill)
3. For each selected source, check if the required env var / credentials exist. If missing, provide setup instructions:
   • Fireflies: "Set FIREFLIES_API_KEY in your environment. Get your API key from https://app.fireflies.ai/api"
   • Slack: "Set SLACK_BOT_TOKEN in your environment. Create a Slack app at https://api.slack.com/apps"
   • Google Drive: "Run the google-workspace skill setup to configure OAuth."
4. For each enabled source, gather configuration:
   • Fireflies: search terms (or leave empty for all recent) and days_back
   • Slack: which channels to pull from — list available channels if possible, otherwise ask the user
   • Google Drive: search terms, days_back
5. Save to ~/.config/casper/linkedin-sources.md
6. Confirm: "Source config saved. Run /casper:generate-linkedin-post --refresh to pull fresh content."

--refresh

Pull fresh source material from all configured integrations before generating posts. Read references/source-integrations.md for the full integration workflow.

Summary of the flow:

1. Read ~/.config/casper/linkedin-sources.md — if missing, run --setup-sources first
2. For each enabled source, call the existing Casper skill scripts:
   • Fireflies: python ${CLAUDE_PLUGIN_ROOT}/skills/transcript-search/scripts/fireflies_transcript_search.py "{term}" --days-back {N} --content --json
     • After fetching, filter results to only transcripts where user_email (from source config) appears in the transcript's participants array
   • Slack: python ${CLAUDE_PLUGIN_ROOT}/skills/slack-automation/scripts/slack_search.py read "{channel}" --days {N}
   • Google Drive: python ${CLAUDE_PLUGIN_ROOT}/skills/google-workspace/scripts/gdrive_search.py files "{term}" --modified-days {N} --json
3. Convert JSON output to clean markdown and save to source-material/:
   • Fireflies: fireflies-{YYYY-MM-DD}-{title-slug}.md
   • Slack: slack-{channel}-{YYYY-MM-DD}.md
   • Google Drive: gdrive-{title-slug}-{YYYY-MM-DD}.md
4. Proceed with normal generation

--view-style

Read ~/.config/casper/linkedin-style.md and display it. If it doesn't exist, say "No style profile found. Run /casper:generate-linkedin-post --setup to create one."

--view-sources

List all .md files in ${CLAUDE_PLUGIN_ROOT}/skills/linkedin-post-generator/source-material/ (excluding README.md). For each file, show the filename and a 1-line summary of its contents.

--add-source

1. Ask: "Paste the content you want to add as source material (meeting transcript, Slack dump, notes, etc.)"
2. Ask: "What should I name this source file? (e.g., team-standup-jan-2025)"
3. Save as ${CLAUDE_PLUGIN_ROOT}/skills/linkedin-post-generator/source-material/[name].md
4. Confirm: "Source material saved. It will be included in future post generation."
