OpenClaw Master Skills is a curated, regularly updated collection of skills that extends an AI personal assistant platform with capabilities such as research, browser automation, presentation creation, and prompt work. It is intended for people using OpenClaw or MyClaw.ai to give their agents additional tasks and workflows. The catalogue contains many skills and agents from this collection.
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.

SkillSpector: 1 finding, 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 Excessive Agency · line 9 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
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 | $0.00080 | $0.03754 |
| Opus 5 | $0.00040 | $0.01877 |
| Sonnet 5 | $0.00016 | $0.00751 |
| Haiku 4.5 | $0.00008 | $0.00375 |
Grade A, and why
agent-otc-trade 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 — 335 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent OTC Trade
Overview
Facilitates over-the-counter trades between agents using Uniswap as the trustless settlement layer. Instead of agents manually coordinating trades through ad-hoc channels, verifying each other's identity, agreeing on prices, and handling settlement independently, this skill provides a structured pipeline: verify counterparty identity via ERC-8004, agree on terms using Uniswap pool prices as the reference rate, and settle atomically through Uniswap pools.
Why this is 10x better than manual agent-to-agent trading:
- Counterparty verification: Before any trade, the counterparty agent's identity is verified via ERC-8004 on-chain registries. Without this, agents trade blindly -- trusting addresses they've never interacted with. The skill checks identity, reputation score, and trust tier, refusing to trade with unverified agents.
- Fair pricing via Uniswap oracle: OTC trades use Uniswap pool prices as the reference rate, preventing either party from proposing unfair terms. The skill shows the current pool price, the proposed OTC price, and the premium/discount so both parties have full transparency.
- Atomic settlement: Trades settle through Uniswap pools in a single transaction. No escrow risk, no counterparty default risk, no partial fills. The pool provides guaranteed liquidity at the agreed price.
- Cross-chain support: For agents on different chains, settlement uses ERC-7683 cross-chain intents. Without this skill, cross-chain OTC trades require manual bridge coordination -- a multi-step process prone to stuck transactions and timing mismatches.
- Audit trail: Every OTC trade is recorded with counterparty identity, agreed terms, settlement transaction, and fees. This creates a verifiable history for reputation building and dispute resolution.
When to Use
Activate when the user says anything like:
- "Trade tokens directly with another agent"
- "Settle an agent-to-agent trade through Uniswap"
- "Execute an OTC swap with agent 0x..."
- "Buy tokens from agent 0x... using Uniswap"
- "Set up a direct trade with a counterparty agent"
- "OTC trade 1000 USDC for UNI with agent 0x..."
- "Settle a service payment with another agent via Uniswap"
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.
