A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

This skill carries the platform-specific mechanics the octoweb:trend agent needs to harvest LinkedIn — current algorithm signals, harvest URLs, scoring on dwell-and-comment economics, hook taxonomy engineered for the 210-char fold, dead patterns, timing. The agent owns the shared DNA loop; this skill plugs the LinkedIn parameters into it.
LinkedIn's 2026 ranker is dwell-time + comment-quality + reshare-with-commentary on top of a 48–72h feed lifetime (10× longer than X). Likes are decorative. Comments and reshares are amplification. The 210-char fold ("...see more") is the entire game — a post that doesn't earn the expand click is dead. Native uploads (PDF carousel, native video) beat external links ~3–5× on reach. External links in the root post drop reach 40–60% — link in first comment.
| Signal | Effect |
|---|---|
| Comment-to-reaction ratio | Primary signal. >5% strong, >10% breakout |
| Reshare with commentary | Weighted higher than empty reshare |
| Author replies to comments in first 60 min | Keeps post in feed longer |
| Dwell time (proxied by post length + paragraph rhythm) | Heavily weighted |
| Reaction diversity (Like + Celebrate + Insightful + Support) | Multi-audience reach signal |
| External link in body | ~40–60% reach penalty |
| Native PDF carousel | ~3–5× reach vs text-only |
| Native video (<90 sec, auto-captioned) | High lift |
| Creator Mode / Top Voice badge | +10–25% baseline reach |
| Posted from company page | ~1/4 the reach of same content posted personally |
| Surface | URL | Yields |
|---|---|---|
| Content search, relevance | https://www.linkedin.com/search/results/content/?keywords=<topic>&sortBy=%22relevance%22 | Algorithm's pick of top posts on topic |
| Content search, date | https://www.linkedin.com/search/results/content/?keywords=<topic>&sortBy=%22date_posted%22 | Last-week live posts |
| Hashtag feed | https://www.linkedin.com/feed/hashtag/?keywords=<tag> | Topic communities (LinkedIn does use hashtags) |
| Creator recent activity | https://www.linkedin.com/in/<handle>/recent-activity/all/ | Last 30 days per anchor creator |
| Signed-in feed | https://www.linkedin.com/feed/ | Personalized algorithmic surface for the user |
Run 4–6 in parallel. LinkedIn lazy-loads aggressively — scroll 3–5× between snapshots to surface enough posts.
Virality axis 0–5:
Niche-fit axis 0–5 — universal scale.
Drop everything below 3 on either axis.
The hook must (a) sit fully above the 210-char fold and (b) create a gap the reader must close to keep reading.
| Goal | Length | Format |
|---|---|---|
| Virality | 150–300 chars | Single, sharp, no expand needed |
| Depth (sweet spot) | 1300–2000 chars | Story / framework, must earn expand |
| Authority | 2000–3000 chars | Long-form thinking, dwell-time bait |
| Carousel (PDF) | 8–12 slides | Strongest reshare format in 2026 |
| Native video | 30–90 sec, auto-captioned | High reach lift |
The 1300–2000 char band is the dwell-time sweet spot. Shorter posts can go viral but rarely generate the comment volume LinkedIn rewards.
Replace "Agree?" / "Thoughts?" with a real question. "Has anyone tried X in production? Did it actually behave the way I'm describing?" wins comments. Vague closings get scroll-past.
LinkedIn's tech-niche saturated takes in 2026 cluster around: "AI will replace developers," "Engineering hiring is broken because of AI," "I built X in a weekend with Claude/Cursor," "AGI will arrive by ...," generic "founders should learn to code" / "founders shouldn't code" cycles. Verify saturation live before flagging.
