Overview

Wolffish searches for today’s top AI news, writes a LinkedIn post in your voice, and publishes it to LinkedIn using your existing Chrome session. No LinkedIn API. No OAuth. Just web search + computer use.

Video Walkthrough

​
Setup

​
Required

  • Wolffish installed and running
  • Claude Opus API key — configured in Settings > Models. This workflow chains research, curation, writing, and multi-step computer-use. Opus handles the judgment calls significantly better than smaller models. Sonnet works but expect lower-quality curation. Haiku and local models are not suitable.
  • Chrome — installed with a profile already logged into LinkedIn. The agent uses your existing browser session directly — no LinkedIn API, no OAuth tokens.
  • macOS permissions — Screen Recording, Accessibility, and Automation. All three in System Settings > Privacy & Security.
What it does: Lets Wolffish take screenshots of your desktop.What happens without it: computer_screenshot silently fails — the agent retries up to 10 times, burning ~300 seconds per attempt before giving up. No error message, just a blank result.How to grant it:
  1. Open System Settings > Privacy & Security > Screen Recording
  2. Click the + button, find and add Wolffish
  3. Restart Wolffish — this permission doesn’t take effect until the app restarts
What it does: Lets Wolffish control the mouse and keyboard.What happens without it: computer_mouse_click and computer_keyboard_type fail immediately with “not permitted.”How to grant it:
  1. Open System Settings > Privacy & Security > Accessibility
  2. Click the + button, find and add Wolffish
  3. Takes effect immediately — no restart needed
What it does: Lets Wolffish send commands to other apps (Chrome, Finder, etc.) via AppleScript.What happens without it: Any osascript call fails with “Not authorized to send Apple events.” The agent retries — in one test run it burned ~264 seconds on 6 retries before succeeding after the prompt appeared.How to grant it:
  1. Open System Settings > Privacy & Security > Automation
  2. Find Wolffish in the list
  3. Toggle on each target app the agent needs — at minimum, Google Chrome
  4. macOS may also prompt you on first use — click “OK” when it does
Grant all three before your first run. If any permission is missing, the agent will burn through its token budget retrying failed tool calls. Screen Recording is the worst — it fails silently, so the agent doesn’t even know it can’t see the screen.

​
Optional

  • Brave Search API key — configured in Settings > Services > Brave Search. Improves search quality.

​
Before You Start

Leave Chrome open with your LinkedIn session active. The agent uses your existing window — it does not spin up a new browser.

​
The Prompt

Send this to Wolffish. It researches, writes, and posts — one conversation. 
Research today's top AI and tech news. Run multiple searches:
"AI news today", "LLM breakthroughs this week", "artificial
intelligence announcements", "AI funding rounds", "AI policy
regulation". Read the full content of the top articles using
web_fetch.

ONLY use free, open sources that web_fetch can read without
hitting a paywall. Good sources: The Verge, Ars Technica,
TechCrunch, arXiv, Papers With Code, Anthropic Blog, OpenAI
Blog, Google AI Blog, Hacker News, r/MachineLearning,
VentureBeat, The Register, CNBC Technology.

DO NOT fetch from paywalled sites — Bloomberg, WSJ, NYT,
Financial Times, The Information. They return HTTP 403 and
waste time. If a search result points to a paywalled domain,
skip it and pick the next one. Also skip SEO spam, listicles,
AI-generated summaries of summaries, and aggregator sites that
rewrite other outlets with no original reporting.

Write a LinkedIn post in my voice (match soul.md tone). Under
3000 characters. Use this exact format — every line break matters:

🤖 AI News Roundup — N Things You Need to Know Today
(blank line)
1. [topic emoji] [One-sentence headline with full context]
(blank line)
2. [topic emoji] [One-sentence headline with full context]
(blank line)
3. [topic emoji] [One-sentence headline with full context]
(blank line)
... continue for 5-10 stories ...
(blank line)

Rules:
- 5 to 10 stories depending on what's newsworthy today
- Each story is exactly one numbered item with a topic emoji
  that matches its domain: 🏦 finance, 🏥 health, 🔬 research,
  💰 funding, 🛡️ policy, 🛒 retail, ☁️ cloud, 🔐 security,
  🎵 consumer, etc.
- Each item is one self-contained sentence — the reader must
  understand the story without clicking through
- One blank line between EVERY item — no exceptions — without
  them LinkedIn renders it as a wall of text
- No hashtags. No closing hot take. No personal reflection.
  The value is the curation.
- End with: Generated with Wolffish 🐟

After writing the post, publish it to LinkedIn using
computer-use. My Chrome browser is already open on display 0
(primary display) with my LinkedIn session logged in and ready
to use. Do NOT spin up a new browser instance. Do NOT use a
headless browser. Do NOT launch Playwright or any automation
framework. Use my existing Chrome window — it's already there.

Begin by taking a screenshot to see the current screen state.

Then save the post with correct encoding:
Generate a timestamped filename using the current date and
time: files/linkedin-post-YYYY-MM-DD-HHMMSS.txt (e.g.
files/linkedin-post-2026-05-22-143052.txt). Write the post
content to that file so emojis are saved with proper UTF-8
encoding. Then copy it to the clipboard using this exact
shell command (with your actual filename):
LANG=en_US.UTF-8 pbcopy < files/linkedin-post-YYYY-MM-DD-HHMMSS.txt
This forces pbcopy to read the file as UTF-8 regardless of
the terminal's locale — it prevents emoji corruption (e.g.
🤖 turning into ü§ñ) that happens with raw copy-paste.

Then post it:
Navigate to: https://www.linkedin.com/feed/?shareActive=true
This opens the post composer directly AND the text area is
already focused with the cursor blinking — ready for input
immediately. Do NOT click the composer text area. Just run
the paste command (Cmd+V) right away to paste from the
clipboard.

After pasting, take ONE screenshot of the composer. Verify
the emojis and formatting look correct — numbered items,
topic emojis, blank lines between stories. If it looks right,
click the "Post" button immediately. Do not scroll through
the post. Do not take additional screenshots to verify. Do
not try to get the post URL after posting.

Four actions total: save file, clipboard-paste, verify, post.
Done.

​
How It Works

  1. Prefrontal loads soul.md + web-search SKILL.md + computer-use SKILL.md into context.
  2. The LLM calls web_search across multiple queries — news, breakthroughs, funding, policy.
  3. The LLM calls web_fetch on the top articles to read full content.
  4. The LLM curates 5-10 stories and writes the formatted post.
  5. The LLM saves the post to a timestamped file and copies it to clipboard via pbcopy.
  6. The LLM takes a screenshot of the existing Chrome window to orient itself.
  7. The LLM opens linkedin.com/feed/?shareActive=true — composer opens focused — and pastes with Cmd+V.
  8. One screenshot to verify formatting, then clicks “Post”.

​
Limits

  • First-time computer-use may trigger macOS Automation prompts — pre-grant them in Setup
  • If LinkedIn’s UI changes layout, the LLM adapts on the next screenshot — no hardcoded selectors

Automating with Heartbeat

Once you trust the output, schedule it to run automatically. Open Settings > Heartbeat to launch the built-in heartbeat editor — paste the block below and save. See the Heartbeat docs for all schedule formats (Daily, Weekday, Weekly, Cron).
