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 | $0.00090 | $0.01420 |
| Opus 5 | $0.00045 | $0.00710 |
| Sonnet 5 | $0.00018 | $0.00284 |
| Haiku 4.5 | $0.00009 | $0.00142 |
Grade A, and why
s4h-strategy-deception 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Strategy: Deception
Sun Tzu's most provocative statement: "All warfare is based on deception." Its operational meaning is not that lying is the path to victory. It is that controlling what your opponent believes about you is as important as controlling what you do. A general who moves in predictable, transparent ways gives the opponent full information and eliminates the element of surprise. A general who manages information deliberately — signaling strength where they are strong, concealing weakness, appearing where unexpected — compounds their effective advantage at no additional resource cost.
In legitimate competitive contexts — negotiation, market positioning, competitive product strategy, organizational politics — managing information asymmetry is standard practice. Revealing your walk-away point in a negotiation, publishing your roadmap before it's locked, announcing your strategy before executing it: each of these transfers advantage to the other side. The discipline is not dishonesty; it is choosing what to make visible and what to protect.
One structural constraint governs everything: whatever you conceal must be consistently concealed. A single inconsistency destroys the deception more efficiently than disclosure. Inconsistency broadcasts that you are managing information — which is worse than transparency. The cost of a deception that collapses mid-contest is higher than the cost of not deploying it at all.
Important: This skill applies to legitimate competitive contexts where information management is appropriate — commercial negotiation, competitive strategy, organizational positioning, market timing. It does not apply to fraud, manipulation of parties in positions of vulnerability, or deception that causes disproportionate harm to people who cannot protect themselves.
Your Process
Step 1: Information to protect What knowledge of your position or intentions, if known by the opponent, would disadvantage you? Be specific. Not "our strategy" (too vague) but "the fact that we have no alternative vendor and our current contract expires in 60 days." List each piece of protective information separately.
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-strategy-deception is a skill published in the GitHub repository human-avatar/skills-for-humanity (223 stars, last pushed 1mo ago), licensed MIT. It adds 90 tokens to every session and 1,420 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.
