From sharpen
This skill should be used when the user asks to "sharpen", "sharpen this tweet", "sharpen my post", "review my tweet", "pressure test this", "simulate reactions", "how will people react to this", "make this tweet better", "improve this post", "tighten this up", or pastes a draft tweet, thread, or social post for feedback. Simulates realistic Twitter, Hacker News, and Reddit reactions, synthesises the feedback into pointed questions, refines the draft, and copies the final version to the clipboard.

Simulate the classic HN thread:
Format: username (N points, Mh ago): comment text
Pick the most relevant subreddit and simulate:
Format: u/username [±N]: comment text
After presenting all simulated reactions:
Questions should probe:
Based on the answers, produce a refined version. Respect platform constraints — keep X/Twitter rewrites within 280 characters unless the draft is explicitly a thread. Briefly note what changed and why.
Copy the final text to the clipboard:
printf '%s' 'FINAL TEXT HERE' | pbcopy
Note: pbcopy is macOS. On Linux, substitute xclip -selection clipboard.
Use printf '%s' with single quotes to prevent shell interpretation. If the text contains single quotes, escape with '\''.
Confirm: "Copied to clipboard. Ready to paste."
If further iteration is requested, repeat from Step 2 with the new version.
npx claudepluginhub withqwerty/plugins --plugin sharpenCritiques complete or near-complete essays with severity-ranked feedback capped at 600 words. Opens with top fix, weaves in strengths, closes with simulated social media reactions.
Scores X/Twitter posts for viral potential using a 19-element heuristic system based on X's published recommendation architecture. Rewrites drafts to improve algorithmic reach and debugs underperforming tweets.
Analyzes and rewrites tweets using Twitter's algorithm insights (Real-graph, SimClusters, TwHIN) to boost engagement signals like likes, replies, and retweets for maximum reach.
