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 | $0.00096 | $0.01736 |
| Opus 5 | $0.00048 | $0.00868 |
| Sonnet 5 | $0.00019 | $0.00347 |
| Haiku 4.5 | $0.00010 | $0.00174 |
Grade A, and why
s4h-writing-argument 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing: Argument
Arguments fail not in the evidence but in the warrant — the unstated principle connecting evidence to claim. The warrant is the assumption that makes the argument work. Most writers never surface it, because to them it is obvious. But the reader may be supplying a different warrant — and reaching a different conclusion from the same evidence.
The structure of every argument:
- Claim: What you are asserting to be true
- Evidence: The facts, data, examples, or observations that support it
- Warrant: The principle or assumption that connects the evidence to the claim
Example: "Remote workers are more productive (evidence). Therefore we should adopt a remote work policy (claim)." The warrant — "policies should be adopted when they increase productivity" — sounds obvious but is not. A reader who believes "productivity must be balanced against team cohesion and culture" will not accept the warrant, and the argument fails for them even if the evidence is strong. Making the warrant explicit forces both writer and reader to examine the actual assumption.
The second most common failure: the strongest counterargument is not addressed. An argument that doesn't engage its best objection is not a complete argument — it is a one-sided brief that any reader with reservations can dismiss. Addressing the counterargument, not to concede but to answer it, is what makes an argument persuasive rather than merely insistent.
Your Process
Step 1: Central Claim State the argument's claim in one sentence. Be specific: "We should adopt a four-day work week" is more specific than "Work-life balance matters." The more specific the claim, the more clearly the evidence can be evaluated against it. A claim that can't be stated specifically is often a claim that hasn't been formed yet.
Framing check: Confirm the specific argument before continuing. State what you've identified — the actual claim being argued and the context or piece it appears in — in one sentence, then use AskUserQuestion:
- Question: "I'm reading this as: [your one-sentence framing of the specific argument and its context]. Is that right?"
- Header: "Framing"
- Options:
- Yes — proceed — framing is correct
- Adjust — one element is off; user will correct it before you continue
- Reframe — different argument than read; incorporate the correction before proceeding
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.

s4h-writing-argument is a skill published in the GitHub repository human-avatar/skills-for-humanity (223 stars, last pushed 1mo ago), licensed MIT. It adds 96 tokens to every session and 1,736 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
