Interact with QR Coin auctions on Base. An agent skill from BankrBot/skills.

  • Works in 3 steps: Approve USDC (One-Time) → Create a New Bid → Contribute to Existing Bid
  • The user wants to participate in qrcoin.fun QR code auctions — check auction status
  • SKILL.md covers Contracts (Base Mainnet), How It Works, Auction Status Queries and Transactions via Bankr, plus 5 more sections
  • Calls curl and jq; reaches mainnet.base.org and grokipedia.com

What it does

Qrcoin is an agent skill from BankrBot/skills. Interact with QR Coin auctions on Base. Use when the user wants to participate in qrcoin.fun QR code auctions — check auction status, view current bids, create new bids, or contribute to existing bids. QR Coin lets you bid to display URLs on QR codes; the highest bidder's URL gets encoded.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `catalog.json`).

It works with Circle USDC. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.

When your agent uses it

  • The user wants to participate in qrcoin.fun QR code auctions — check auction status
  • View current bids
  • Create new bids
  • Contribute to existing bids

Example prompts

  • “/qrcoin”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Approve USDC (One-Time)
  2. Create a New Bid
  3. Contribute to Existing Bid

What it can do on your machine

Read from SKILL.md and the folder at commit dc47eed. 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

    Shell commands in SKILL.md call:

    • curl
    • jq

    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:

    • mainnet.base.org
    • grokipedia.com

    Also links to:

    • qrcoin.fun
    • basescan.org

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

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Qrcoin loads about 1.6k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 498 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 498 words (~1,637 tokens).

“Participate in QR Coin auctions on Base blockchain. QR Coin lets you bid to display URLs on QR codes — the highest bidder's URL gets encoded when the auction ends.”
