trend-hackernews — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited trend-hackernews (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

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 Hacker News — current ranking signals (point velocity × comment depth × flag-tax × age-decay), harvest URLs, title rules from HN guidelines, Show HN / Ask HN / link-submission patterns, anchor commenters, dead patterns. The agent owns the shared DNA loop; this skill plugs the HN parameters in.
HN is one audience with one strict culture: skeptical, technical, anti-marketing, anti-listicle. The ranker is point velocity × comment depth × flag-tax × age-decay. Point velocity in the first 90 minutes is the entire game — a post is either on the front page or dead after that. Comments boost ranking sub-linearly but heavily — a post with 50 points and 80 comments often outranks one with 100 points and 5 comments. Flags are anonymous and powerful — 3–5 flags can sink a climbing post. A title that wins on Reddit dies on HN in 4 minutes if it editorializes or sounds like marketing.
| Signal | Effect |
|---|---|
| Points per hour, first 90 min | Primary signal. >30/h = front-page-bound, >60/h = breakout |
| Comment-to-point ratio | Discussion signal. >30% high, >50% contested |
| Survival past 90 min | Most posts die in new. Still on front page at 4h = winner |
| Flag tax | Visible [flagged] or sudden rank drop despite point accumulation |
| Domain authority bias | github.com / arxiv.org / personal blogs get small lift; SaaS company blogs get tax |
| Submitter karma band | Visible on profile; low-karma submitters get more flag-prone |

DO:
DO NOT:
Show HN pattern: Show HN: <noun phrase, what it is> — <one-clause clarifier if needed> Ask HN pattern: Ask HN: <direct question, no preamble>
Show HN — first author comment with:
Ask HN — body sets up the question with 3–6 lines of concrete context (specific situation, what you tried, where you're stuck). Vague Ask HN dies.
Link submissions — no body needed. First-comment from submitter sometimes worth it if the article is dense.
Specific high-karma users reliably comment on niche threads. Identify them during harvest — their participation often signals the post will survive the front-page filter. Do not @-mention them in the post (HN doesn't support that culturally) but note them for the user's awareness.
HN's tech-niche saturation cycles fast. Run Algolia "pastWeek" search on the user's topic terms. If 5+ front-page posts hit the same angle in the last 7 days, mark saturated. Common 2026 saturated angles in agents / LLM space: "Why we moved off OpenAI / off Anthropic," "Why we built our own RAG," "GPT-X benchmark results," generic "agent failure" post-mortems without specifics.
Bad — count without context:
Show HN post got 400 points yesterday.Good — velocity, flag-state, domain, anchor commenters labeled:
"Show HN: {{tool name}} – local agent eval harness"
412 pts / 187 comments / 5h on front page / 82% upvote-implied / not flagged
Submitter: {{handle}} (karma 3,400 — credible)
Domain: github.com — domain trust bonus
Front-page entry: 14 minutes after submission (very fast climb)
Points/hour first 4h: ~75/h (breakout band)
Anchor commenters participating: {{handle1}}, {{handle2}} — high-karma niche regulars
Title type: Show HN, noun phrase + one-clause clarifier
First-comment author post: 5 lines — what it is, problem it solves, stack, free / paid, known limits

Submitter karma: 120 (new account)
Domain: marketing-domain.com
Inferred flag reason: SaaS-launch tone + marketing domain + new-account submitter + non-Show-HN format
