Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.01591 |
| Opus 5 | $0.00022 | $0.00796 |
| Sonnet 5 | $0.00009 | $0.00318 |
| Haiku 4.5 | $0.00004 | $0.00159 |
Grade A, and why
content-hackernews scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hacker News Content Generation
Before You Start
-
Understand HN culture: Hacker News (news.ycombinator.com) is a community driven by intellectual curiosity and technical depth. It is run by Y Combinator and attracts founders, engineers, researchers, and technically sophisticated readers. The community is allergic to marketing, superlatives, and hype.
-
Determine post type:
- Show HN: Sharing something you have built for community feedback
- Ask HN: Asking the community a question
- Standard submission: Sharing a link to content (your own or someone else's)
-
Check for brand voice: Read
brand/VOICE.mdif it exists, then heavily adapt it usinghn-voice.md. HN has the strictest voice requirements of any platform. Marketing language of any kind will get the post flagged, downvoted, or ignored.
HN Culture
What HN Values
- Intellectual curiosity and genuine interest in ideas
- Technical depth and rigorous thinking
- Honesty, especially about limitations and trade-offs
- Novel insights and original thinking
- Clear, direct writing without embellishment
- Substance over polish
What HN Rejects
- Marketing language of any kind ("revolutionary," "game-changing," "disruptive")
- Superlatives ("the best," "the fastest," "the most powerful")
- Emotional manipulation or engagement bait
- Clickbait titles
- Self-congratulation
- Hype without substance
- Excessive self-promotion without proportional community contribution
The HN Audience
- Technically sophisticated: assume your reader can evaluate technical claims
- Detail-oriented: vague claims will be challenged in comments
- Skeptical of hype: extraordinary claims need extraordinary evidence
- Global: readers span every timezone and many industries
- Time-constrained: they scan titles and click selectively

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

content-hackernews is a skill published in the GitHub repository vstorm-co/content-skills (22 stars, last pushed 4mo ago), licensed MIT.
