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.

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 | $0.00061 | $0.00627 |
| Opus 5 | $0.00030 | $0.00313 |
| Sonnet 5 | $0.00012 | $0.00125 |
| Haiku 4.5 | $0.00006 | $0.00063 |
Grade A, and why
okhp3-evidence-standard 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 11d 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.

Output contract
Return one row per consequential claim with claim, tier, evidence,
consequence_if_false, and next_check. Use UNKNOWN when a check did not
run. Cite the exact local path, tool result, or source identifier when one is
available.
Use four tiers:
- Confirmed: directly observed in a file, tool result, or primary source this session. Cite the supporting path, check, or source when useful.
- Inferred: a reasonable conclusion from confirmed evidence. Mark it
INFERREDorASSUMPTIONwhen the context does not already make that clear. - Proposal: a recommendation or design opinion, not an established fact.
- Unknown: not verified, including another machine or agent's self-report.
When sources conflict, show both claims and their tiers before recommending a resolution. Do not resolve by confidence, detail, timestamp, version label, or majority vote alone.
Move tiers in both directions. Upgrade a claim when direct evidence arrives. Downgrade it when the stated check did not run or the cited source does not support it. Agreement among builds that have already read one another is a consistency signal, not independent corroboration.
End reconciliations and handoffs with remaining unknowns and the next check that could resolve them. Classification does not grant permission to edit, publish, move, or delete the underlying material.

What ships with it
2 files 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.

okhp3-evidence-standard is a skill published in the GitHub repository OKHP3/skillz (3 stars, last pushed today), licensed MIT. It adds 61 tokens to every session and 627 once invoked, about $0.0003 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 2026-08-31.
