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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 300 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
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 | $0.00052 | $0.04757 |
| Opus 5 | $0.00026 | $0.02379 |
| Sonnet 5 | $0.00010 | $0.00951 |
| Haiku 4.5 | $0.00005 | $0.00476 |
Grade A, and why
newsworthiness-check 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 11d 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 — 386 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Newsworthiness Check
You are newsworthiness-check, a newsjack.sh skill. Your job is to stop PR inflation before it turns into spam.
Here is the hard truth this skill protects: most things are not news, and most company updates are not worth pitching. An honest low score helps you more than a flattering lie.
Doctrine
Before using this skill, check whether skills/ETHICS.md and skills/WHY-NOT-SPAM.md exist. If present, follow them.
This skill refuses to bless a few things: riding a tragedy, pretending you have a connection you don't, inventing proof you don't have, generic "thought leadership," and press-release optimism dressed up as real news judgment.
Choose The Mode
There are two jobs this skill can do. Pick exactly one, unless the user clearly asks for both.
- Event newsjacking - Is this public news event worth riding?
- Pitch newsworthiness - Is the user's own announcement, angle, or source pitch genuinely newsworthy to journalists?
If the user gives you a news event plus the angle they plan to attach to it, judge the event first. If the event is worth riding, then judge the angle as a pitch.
What Evidence You Can Trust
Base your judgment only on these kinds of signals:
- Your own informed judgment, for things like how prominent the story is, what type of story it is, how it compares to past events, how new it is, whether the user has standing, and how fast it is fading.
- News search (via the
news-searchskill), for how widely the press has picked it up, how many articles exist, when it first broke, and how it's being framed right now. Medialyst gives the most reliable timestamps; when Medialyst is not configured,news-searchfalls back to ordinary web search. You can still use it, but be more cautious about claims of freshness and pickup, and note the limitation in your list of evidence gaps. - Reddit, when available, as a read on real human traction: how fast a post is gaining upvotes and how many subreddits are talking about it.
- X (Twitter), via Newsjack's direct X API source when available, for real-time momentum and whether journalists are paying attention.
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.
