What it can do on your machine

Read from SKILL.md and the folder at commit 8925799. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • link.x402labs.dev
    • sepolia.base.org

    Also links to:

    • mainnet.base.org
    • rpc.sepolia.org
    • eth.llamarpc.com

    From URLs in SKILL.md, links to its own repository left out.

Context cost

Payment loads about 1.5k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 479 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
