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 | $0.00072 | $0.02528 |
| Opus 5 | $0.00036 | $0.01264 |
| Sonnet 5 | $0.00014 | $0.00506 |
| Haiku 4.5 | $0.00007 | $0.00253 |
Grade A, and why
hacker-news-strategy 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 10d 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 — 323 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hacker News Strategy
Hacker News is the most influential developer community — and the easiest to get wrong. This skill covers what actually works, what gets you flagged, and how to build authentic presence.
Before You Start
- Read
.agents/developer-audience-context.mdif it exists - Check if the product/content is genuinely interesting to HN's audience (hackers, founders, deep tech enthusiasts)
- Be honest: HN users can smell marketing from miles away
Understanding HN's Culture
Who's Actually on Hacker News
| Segment | What they care about |
|---|---|
| Founders | Fundraising, growth tactics, startup war stories |
| Senior engineers | Deep technical content, architecture, systems |
| Tech leads | Engineering management, team scaling, processes |
| Indie hackers | Solo projects, bootstrapping, revenue |
| Researchers | AI/ML, distributed systems, PLT, security |
What HN Values
- Technical depth over marketing polish
- Genuine novelty over incremental updates
- Transparency over corporate speak
- Building in public over stealth launches
- Contrarian insights over conventional wisdom
What HN Hates
- Self-promotion disguised as content
- Clickbait headlines
- Corporate PR speak
- Engagement bait ("What do you think?")
- Anything that feels like an ad
Post Types and When to Use Them
Show HN
Use when: You built something and want feedback from the community.
| Requirement | Details |
|---|---|
| Must be something people can try | Live demo, downloadable, or detailed walkthrough |
| Must be new | Not a repost or minor update |
| Creator must be available | Answer questions in comments for 2-3 hours |
| Title format | "Show HN: [Name] – [One-line description]" |
Good Show HN examples:
- "Show HN: I built a SQLite extension for vector search"
- "Show HN: Open source Heroku alternative written in Rust"
- "Show HN: Real-time collaborative code editor in the browser"
What ships with it
1 file 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.
