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 | $0.00124 | $0.01220 |
| Opus 5.5 | $0.00050 | $0.00488 |
| Sonnet 5.5 | $0.00025 | $0.00244 |
| Haiku 4.5 | $0.00012 | $0.00122 |
Grade A, and why
s4h-logic-consistency-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 1mo 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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Logic Consistency Check
Requirements drift. Specs accumulate. A document written over weeks by multiple people — or a set of decisions made incrementally — can contain contradictions that nobody noticed because each piece was reviewed in isolation.
This skill reads the whole and finds where the parts disagree.
Your Process
Step 1: Map the claims Before checking for consistency, inventory what the document asserts:
- Goals and objectives stated
- Constraints and non-negotiables stated
- Assumptions stated or implied
- Decisions and their stated rationale
- Any numbered requirements or acceptance criteria
This map is what gets checked for internal coherence — not whether any claim is true, but whether the claims are consistent with each other.
Framing check: Confirm the specific document or set of claims before continuing. State what you've identified — the actual object being analyzed and its key parameters (document type, scope, primary claims in tension) — in one sentence, then use AskUserQuestion:
- Question: "I'm reading this as: [your one-sentence framing of the specific document or claim set being checked]. 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 situation than read; incorporate the correction before proceeding
Step 2: Check goal-constraint conflicts Do the stated goals require violating stated constraints? Common patterns:
- A performance goal that requires more resources than the budget allows
- A simplicity goal combined with a feature list that requires complexity
- A timeline that requires skipping steps the quality requirements depend on
Step 3: Check requirement-requirement conflicts Do individual requirements contradict each other?
- Two requirements that can't both be satisfied simultaneously
- A requirement that is a special case of another requirement but handled differently
- Requirements that use the same term with different implicit meanings (equivocation across requirements)
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-logic-consistency-check is a skill published in the GitHub repository human-avatar/skills-for-humanity (236 stars, last pushed 3mo ago), licensed MIT. It adds 124 tokens to every session and 1,220 once invoked, about $0.0005 per session on Opus 5.5. 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.
