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.

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 | $0.00079 | $0.01175 |
| Opus 5 | $0.00039 | $0.00588 |
| Sonnet 5 | $0.00016 | $0.00235 |
| Haiku 4.5 | $0.00008 | $0.00118 |
Grade A, and why
x-article-writer 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 12d 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
X Article Writer
Write like a founder with a point of view, not a content marketer filling a page.
What Good Looks Like
A strong X article does three jobs fast:
- Stop the scroll: the title or first line creates a gap.
- Create tension: the reader sees what most people misunderstand.
- Pay it off: the body gives a mechanism, example, teardown, or playbook worth saving.
It should feel like a smart person on X making a sharp case in public, not a blog post pasted into X.
Pick The Spine
Choose one structure before drafting:
| Spine | Use When | Shape |
|---|---|---|
| I changed my mind | The piece has a lesson or reversal | I believed X -> reality showed Y -> now I do Z |
| Everyone is looking at the wrong thing | The obvious take is lazy | People blame X -> the real lever is Y -> here is why |
| Teardown | There is a product, launch, funnel, ad, or channel to analyze | What happened -> why it worked/failed -> what to copy |
| Field note | There is a call, customer, metric, launch, or experiment | Scene -> observation -> broader lesson |
| Playbook | The reader should leave with steps | Outcome -> constraints -> exact moves -> failure modes |
| Market shift | Something has changed in a category | Old rule -> new behavior -> what founders should do now |
Do not mix three spines. One article gets one main argument.
Build The Hook
Write 8-12 title or opening-line options before the body. Use one of these patterns:
- Result with friction: "We got [result]. The weird part was [unexpected cause]."
- Wrong belief: "Most founders think [X]. That's why they miss [Y]."
- Specific scene: "I was looking at [dashboard/call/page] and one thing made no sense."
- Named teardown: "[Company/product/channel] is a masterclass in [specific mechanism]."
- Useful promise: "How to get [outcome] without [common painful tradeoff]."
- Category fight: "[Category] is moving from [old rule] to [new rule]."
- Confession: "I used to think [X]. I was wrong."
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.
