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 | $0.00101 | $0.01295 |
| Opus 5 | $0.00051 | $0.00647 |
| Sonnet 5 | $0.00020 | $0.00259 |
| Haiku 4.5 | $0.00010 | $0.00129 |
Grade A, and why
s4h-epistemology 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Epistemology
Applies philosophical analysis to the nature, structure, and limits of knowledge. Diagnoses what kind of epistemic work is needed and routes to the right tool.
Epistemology is the meta-layer: not "is this claim true?" but "what kind of truth could this claim even have? What would justify believing it? How certain can we actually be?" It's most useful when you've hit a wall with ordinary investigation — when more evidence-gathering won't settle things, when you're not sure what kind of knowing is in play, or when you want honest calibration rather than confident-sounding output.
Which tool fits
| You need to... | Tool |
|---|---|
| Map what kind of knowing is in play | epistemology-knowledge-types |
| Work out what would actually justify believing something | epistemology-justification |
| Get honest calibration: what do I know vs. believe vs. assume vs. hope? | epistemology-epistemic-status |
| Find out what can't be known, and why — and what can be established | epistemology-limits |
Routing Decision
- "What kind of claim is this?" / "Am I reasoning from evidence, intuition, testimony, or something else?" → knowledge-types (classify the epistemic mode before testing the claim)
- "What would it take to actually know this?" / "What would justify believing X?" → justification (map the justification structure and find the weakest link)
- "How certain should I be?" / "Give me an honest read of what we know vs. assume" → epistemic-status (calibrate and map confidence across a domain)
- "Can this even be known?" / "We keep investigating and nothing settles it" → limits (classify the type of limit and reframe into the answerable)
- Unclear → epistemic-status (starts with honest inventory of what's known, naturally surfaces which deeper question matters)
Confirm Direction
After diagnosing which tool fits, use the AskUserQuestion tool to confirm direction. Construct the question dynamically to include your diagnosis:
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-epistemology is a skill published in the GitHub repository human-avatar/skills-for-humanity (223 stars, last pushed 1mo ago), licensed MIT. It adds 101 tokens to every session and 1,295 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.
