SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 42 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Excessive Agency · line 133 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00178 | $0.02329 |
| Opus 5 | $0.00089 | $0.01164 |
| Sonnet 5 | $0.00036 | $0.00466 |
| Haiku 4.5 | $0.00018 | $0.00233 |
Grade A, and why
okx-how-to-play 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 — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Onchain OS — How to Play (Entry Router)
The first-time / "I don't know what to do" entry point. Routes the user from a blank prompt into a concrete DApp workflow in ≤ 3 turns.
Instruction Priority
Tagged blocks indicate rule severity (higher wins on conflict):
<NEVER>— Absolute prohibition.<MUST>— Mandatory step. Skipping breaks the flow.<SHOULD>— Best practice.
Pre-flight Checks
Authoring Pattern — Free Zone vs Fixed Zone
Most user-facing copy in this flow is split into two parts:
- Free zone — the agent answers the user's actual question or acknowledgement first, in 1–5 sentences, contextually woven. No fixed copy. The user shouldn't feel like they hit a script.
- Fixed zone — the canonical English template block (welcome banner, login options, API Key heads-up). At runtime:
- Render all natural-language prose in the user's language.
- Quoted reply words inside prose (e.g.
"login") MUST translate with their sentence. Leaving an English quoted word inside otherwise-translated Chinese / Japanese / etc. prose is a translation bug — the quotes do NOT make the word a literal trigger. - Keep literal: emojis,
{placeholders},1–N, code identifiers / commands / URLs, markdown structure.
This applies to: Welcome Banner, Login Method Choice, and API Key Login Step 1 heads-up.
Status Check
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.

okx-how-to-play is a skill published in the GitHub repository nirholas/three.ws (113 stars, last pushed today), licensed Apache-2.0. It adds 178 tokens to every session and 2,329 once invoked, about $0.0009 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 2026-08-30.
