SkillSpector: 1 finding, up to high
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 →
- high System Prompt Leakage · line 217 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
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 | $0.00297 | $0.03837 |
| Opus 5 | $0.00148 | $0.01919 |
| Sonnet 5 | $0.00059 | $0.00767 |
| Haiku 4.5 | $0.00030 | $0.00384 |
Grade A, and why
okx-dex-swap 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 8d 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 — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Onchain OS DEX Swap
6 commands for multi-chain swap aggregation — quote, approve, one-shot execute, and calldata-only swap.
Stack arbitration. three.ws has two swap stacks. This OKX
onchainosstack is for OKX-routed swaps the user opted into — by naming OKX/OnchainOS, a specific DEX/DApp venue, or an OKX-specific chain (X Layer, BSC, Arbitrum, etc.). For a plain three.ws-native Base/Polygon swap the user did not route through OKX, defer to thetradeskill (the awal / three.ws-native default).

Command Index
| # | Command | Description |
|---|---|---|
| 1 | onchainos swap chains |
Get supported chains for DEX aggregator |
| 2 | onchainos swap liquidity --chain <chain> |
Get available liquidity sources on a chain |
| 3 | onchainos swap approve --token ... --amount ... --chain ... |
Get ERC-20 approval transaction data (advanced/manual use) |
| 4 | onchainos swap quote --from ... --to ... --readable-amount ... --chain ... |
Get swap quote (read-only price estimate). No --slippage param. |
| 5 | onchainos swap execute --from ... --to ... --readable-amount ... --chain ... --wallet ... [--slippage <pct>] [--gas-level <level>] [--mev-protection] [--force] |
One-shot swap: quote → approve (if needed) → swap → sign & broadcast → txHash. --force bypasses backend risk warning 81362 only after explicit user confirmation. |
| 6 | onchainos swap swap --from ... --to ... --readable-amount ... --chain ... --wallet ... [--slippage <pct>] |
Calldata only: returns unsigned tx data. Does NOT sign or broadcast. |
What ships with it
4 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-dex-swap is a skill published in the GitHub repository nirholas/three.ws (111 stars, last pushed today), licensed Apache-2.0. It adds 297 tokens to every session and 3,837 once invoked, about $0.0015 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.
